Description

  The present invention provides a window frame for displaying an indicator such as a day of the week or a date on a display panel of a device such as a display panel for a clock, a desk calculator, an automobile instrument panel, a mobile instrument such as a mobile phone, etc. The present invention relates to a window frame member disposed in an opening, a display plate, a method for manufacturing the display plate, and a fixing jig therefor.

  2. Description of the Related Art In recent years, solar cell devices, particularly watches, have a solar power generation device including a solar cell (solar cell), and solar watches driven by the power generated by the solar power generation device have become a major market. .

Such a display plate (dial plate) for a solar timepiece is configured to transmit received light and cause a power generation function to occur in a solar power generation device disposed on the lower surface side thereof.
Therefore, a display panel for a solar watch is required to have a certain degree of light transmittance because it transmits light outside the wavelength range that contributes to power generation of the solar power generation device and gives an electromotive force to the solar power generation device. Need to be translucent.

  For this reason, a substrate constituting a display panel for a solar watch is manufactured as a transparent or translucent part by using a soft material such as synthetic resin, paper, cloth, or a brittle material represented by ceramic such as glass. ing.

  On the other hand, a window frame member is arranged on the display panel for the solar timepiece so as to surround the outer periphery of the window frame opening so that a calendar display unit for displaying an indicator such as a day of the week or a date can be seen from above. ing.

  In this case, the window frame member is desired to be made of metal for the reason of giving the user who looks at the display board an aesthetic appearance and a high-class feeling, and such a metal window frame member is preferably made of a soft material or a brittle material. Various means have been conventionally proposed for securely fixing to the display panel. For example, a metal window frame member may be fixed to a display panel made of a soft material or a brittle material by a method such as press fitting or caulking. Adhesive fixing is performed using an adhesive.

  However, since the metal window frame member cannot be firmly fixed to the display board by a method such as press fitting or caulking, for example, when a large impact is applied to the display board, the window frame member is not attached to the display board. There was a risk of falling off.

  In addition, if the metal window frame member is fixed to the display plate by caulking at a high pressure so as not to drop off as much as possible, the window frame member and the display plate are distorted and cracked, resulting in the beauty of the display plate. Has been severely damaged.

  For this reason, conventionally, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2001-42055), as shown in FIGS. 17 to 19, the window frame opening of the substrate 102 made of a soft material or a brittle material constituting the display panel 100. A structure in which a metal window frame member 108 bites and fixes to the inner wall 106 of 104 is proposed.

In other words, the window frame member 108 includes a frame main body 110 inserted into the window frame opening 104 and a decorative edge 101 continuous above the frame main body 110. On the outer periphery of the frame main body 110, a protrusion 112 protruding outward is formed. The decorative edge 101 extends in a flange shape along the planar direction from the frame main body 110 and is formed in a size that cannot pass through the window frame opening 104. The frame main body 110 and the decorative edge 101 are both cut in the vertical direction, and a through window 103 penetrating vertically through the frame main body 110 and the decorative edge 101 is formed.

The window frame member 108 is fixed to the substrate 102 as follows.
The frame main body 110 of the window frame member 108 is inserted into the window frame opening 104 of the substrate 102. Then, the projection 112 of the frame main body 110 is immersed in the inner wall 106 of the window frame opening 104, and the frame main body 110 is fixed in the window frame opening 104. The decorative edge 101 is in contact with the upper surface of the substrate 102 and is located above the substrate 102.

  An observer who watches the clock reads, for example, the date and day of the week on the calendar display unit operating under the substrate 102 through the through window 103 of the window frame member 108. Here, the portions touched by the observer are the upper surface of the decorative edge 101 surrounding the date and day of the calendar display section, and the inner wall of the through window 103. In this case, since the upper surface of the decorative edge 101 and the inner wall of the through window 103 are made of metal, a high-class aesthetic appearance is given to the observer.

A protrusion 112 projecting outward is formed on the outer periphery of the through-hole 110 penetrating the window frame opening 104, and the protrusion 112 is immersed in the inner wall 106 of the window frame opening 104. ), And the window frame member 108 is configured to be fixed to the window frame opening 104.
JP 2001-42055 A

  However, in the display panel 100 of Patent Document 1, when the substrate 102 is made of a soft material, if the projection 112 of the window frame member 108 is immersed in the inner wall 106 of the window frame opening 104, the window frame opening 104 is surrounded by the periphery of the window frame opening 104. When distortion occurs and the periphery of the window frame opening 104 is distorted, discolored, or severely, plastic deformation may occur, and as a result, the aesthetic appearance of the display panel 100 is significantly impaired.

  Further, when a large impact force is applied to the display panel 100 from the outside, the substrate 102 itself is elastically deformed, so that the projection 112 of the window frame member 108 falls off the inner wall 106 of the window frame opening 104. Will end up. As a result, the window frame member 108 often dropped from the substrate 102 due to an impact.

  On the other hand, when the substrate 102 is made of a brittle material, if the protrusion 112 of the window frame member 108 is immersed in the inner wall 106 of the window frame opening 104, the display panel made of the brittle material has cracks around the window frame opening 104. If the window frame opening 104 is severely damaged, the periphery of the window frame opening 104 may be damaged or chipped. As a result, the aesthetic appearance of the display panel 100 is significantly impaired.

In addition, when the window frame opening and the window frame member are bonded and fixed using an adhesive, it is difficult for the adhesive to enter the contact surface between the window frame opening and the window frame member, resulting in a decrease in yield. .
Furthermore, when a diffusion layer is provided on the back surface of the display panel for the purpose of diffusing the reflected light from the back surface side of the display plate, the adhesive enters the diffusion layer and adheres from the display plate surface. The agent was visible, and the aesthetic appearance of the display board was significantly impaired.

In view of such a current situation, the present invention does not drop the window frame member from the display panel even when the display panel itself is elastically deformed by an impact load, and does not apply a large mechanical load to the display panel.

  Even if the substrate constituting the display panel is made of a brittle material, no load is applied to the substrate, so that there is no cracking or breakage around the window frame member of the substrate, and the substrate is missing. In addition, the appearance of the display board is not impaired.

  Therefore, even if the substrate itself is elastically deformed by an impact load, the window frame member does not fall off the substrate, and the window frame member can be firmly fixed to the display board without applying a large mechanical load to the substrate. In addition, it is possible to provide a display panel that is excellent in appearance, good in appearance, and high-quality.

Furthermore, even if a diffusion layer is provided on the back surface of the display plate for the purpose of diffusing reflected light from the back surface side of the display plate, adhesion can be achieved by applying an adhesive to the notch. Since the agent does not flow into the diffusion layer, the adhesive is not visible from the surface of the display panel, and the appearance of the display panel is not impaired.

Hereinafter, embodiments (examples) of the present invention will be described in more detail with reference to the drawings.

Note that the window frame member is also displayed as shown in FIG. 2 when expressed as “3 o'clock direction”, “6 o'clock direction”, “9 o'clock direction”, and “12 o'clock direction” with respect to the window frame member. In the state of being incorporated in the board, it means the right direction, the downward direction, the left direction, and the upward direction, respectively.

  The “vertical direction” means the vertical direction in FIG. Therefore, the upper surface is a surface exposed outward when the wristwatch is worn on the wrist, and the lower surface is a surface facing the wrist in the same state.

  Further, the “planar direction” is a direction orthogonal to the vertical direction, and in FIG. 1, means the front side of the paper surface and the back side of the paper surface, and the planar direction is the longitudinal direction of the band, or It may overlap with the width direction of the band.

As shown in FIG. 1, the solar timepiece 10 with a wireless function includes a housing 12.
The housing 12 is mounted in a sealed state so as to cover, for example, a watch case 14 constituting a substantially cylindrical frame made of metal, synthetic resin, or ceramic, and a lower surface opening of the watch case 14. A back cover 16 made of metal, synthetic resin, or ceramic, and a windshield (glass) 18 mounted in a sealed state so as to cover the upper surface opening of the watch case.

  In addition to the case where the housing 12 has the back cover 16 as described above, there are various cases such as a case where the back cover 16 and the watch case 14 are integrated, and a case where the back cover 16 is also glass. Including cases.

  The housing 12 includes a movement 20 that constitutes a timepiece driving unit, and a solar power generation device 22 that is disposed on the upper surface of the movement 20 and that drives the movement 20 by electromotive force of light.

  Further, on the upper surface of the solar power generation device 22, there is provided a display plate 24 having a light transmitting function that transmits external light having a wavelength contributing to power generation of the solar cell 23 at least enough to drive the movement 20.

Further, an antenna 26 for receiving standard radio waves is attached to the small diameter portion 20a below the side portion of the movement 20.
In this embodiment, the antenna 26 is illustrated as a bar antenna including a rod-shaped magnetic core member serving as a core and a coil wound around the outer periphery of the magnetic core member. Of course, it is also possible to comprise.

  Further, the watch case 14 includes two sets of band attaching portions 28 protruding outward, and these band attaching portions 28 are arranged so as to be opposed to each other and spaced apart from each other. 14 is provided with a leg portion 30 extending from 14.

A wristwatch band (not shown) is connected between each of the leg portions 30.
An hour hand and a minute hand (not shown) are arranged on a needle shaft 31 that protrudes from the movement 20 and penetrates the solar power generation device 22 and the display plate 24. These hour hand and minute hand are located between the display plate 24 and the windshield 18 and display time.

  As shown in FIGS. 1 and 2, the display plate 24 includes a light-transmitting substrate 32 that can transmit light from the outside. In this embodiment, the translucent substrate 32 has a substantially rectangular shape that functions as a mounting through hole so that a calendar display 34 for displaying an indicator such as a day of the week or a date can be seen from above. A window frame opening 36 is formed.

  Further, a metal window frame member 38 having a substantially rectangular frame shape constituting the additional member is attached to the window frame opening 36 of the translucent substrate 32. As shown in FIG. 3, the window frame member 38 includes a flange frame portion 38a having a substantially rectangular frame shape, and a hollow rectangular window frame extending downward with a dimension smaller than the flange frame portion 38a. And a support portion 38b. The outer dimension of the window frame insertion support portion 38b is set to have a dimension that is substantially the same as or slightly smaller than the inner dimension of the window frame opening 36 of the translucent substrate 32.

  Moreover, the dimension of the flange frame part 38a is larger than the internal dimension of the window frame opening part 36 of the translucent board | substrate 32, and, thereby, the window frame insertion support part 38b of the window frame member 38 is translucent. When passing through the window frame opening 36 of the substrate 32, the flange frame 38 a is locked to the upper surface of the outer periphery of the window frame opening 36 of the translucent substrate 32, and the window frame member 38 falls down downward. Is to be prevented.

  As will be described later, for example, a window frame fixing agent such as an adhesive is applied to the outer peripheral 3 o'clock direction and the 9 o'clock direction of the front end portion 38c (back side) of the window frame insertion support portion 38b of the window frame member 38. A notch 38d is provided for installation.

And the window frame insertion support part 38b of this window frame member 38 penetrates the window frame opening part 36 of the translucent board | substrate 32, and becomes fixed with window frame fixing agents, such as an adhesive agent, for example. ing.
In addition, since the window frame member 38 is not disposed on the upper portion of the antenna 26, the antenna 26 can receive radio waves without being affected by the metal window frame member 38, and this causes a decrease in radio wave reception characteristics. Must not.

Further, as shown in FIG. 3, the window frame member 38 is spaced apart from the front end portion 38c of the window frame insertion support portion 38b of the window frame member 38 by two fixed intervals in the 6 o'clock direction and the 12 o'clock direction. A locking piece 42 protruding from the rear surface side of 38 is formed.

In this embodiment, the locking piece 42 is formed in a portion 38e that is in contact with the window frame opening 36 of the distal end portion 38c of the window frame insertion support portion 38b of the window frame member 38.
However, although not illustrated, as will be described later, when the locking piece 42 of the window frame insertion support portion 38b is bent, the locking portion 42a of the bent locking piece 42 is not attached to the translucent substrate 32. In order to prevent the load from being applied to the transparent substrate 32 without contacting the window frame opening 36, the locking piece 42 is inserted into the window frame as shown by the arrow in FIG. It is desirable that it is formed inside a portion 38e that contacts the window frame opening 36 on the back side of the wearing support portion 38b.

  As a result, there is no distortion around the window frame member 38 of the translucent substrate 32, no discoloration, no plastic deformation, no cracks, no breakage, and no aesthetic appearance of the display board. Will not be damaged.

Further, the locking piece 42 is formed with a groove 42b at the base end portion of the locking piece 42, whereby the thickness of the base end portion of the locking piece 42 is made thin.
Further, as shown in FIG. 4, instead of forming the groove 42b in the base end portion of the locking piece 42 as described above, the thickness of the entire locking piece 42 is reduced, although not shown, The thickness of the base end portion of the locking piece 42 can also be reduced.

  In this case, as shown in FIG. 4, a tapered surface 45 inclined inward is formed at the tip of the locking piece 42, as shown in FIGS. When the locking piece 42 of the support portion 38 b is bent and the locking portion 42 a is received in the locking recess or step 44 of the translucent substrate 32, the taper pressing surface 54 of the fixing jig 48. The latching piece 42 of the window frame insertion support portion 38b of the window frame member 38 is bent along with the latching portion 42a of the latching piece 42 so that the latching recess 42 of the translucent substrate 32 is locked. Alternatively, it is desirable to facilitate accommodation in the stepped portion 44.

  As described above, the thickness of the base end portion of the locking piece is formed thin by, for example, forming the groove 42b or the like, so that the locking piece 42 of the window frame insertion support portion 38b is bent. It is easy and the locking piece itself is not easily distorted and the mechanical strength is not lowered. Therefore, the window frame member 38 can be firmly fixed to the window frame opening 36 of the translucent substrate 32. It is possible to prevent the light-transmitting substrate 32 from falling off the window frame opening 36.

  On the other hand, as shown in FIG. 5 and FIG. 6, on the back side of the transparent substrate 32 constituting the display panel, around the back surface of the window frame opening 36, at a position corresponding to the locking piece 42. A recess or step 44 is formed.

  Thus, as will be described later, the window frame member 38 is translucent by bending the locking piece 42 of the window frame insertion support portion 38b and accommodating it in the locking recess or step 44 of the display panel. It is comprised so that it can fix to the window frame opening part 36 of the property board | substrate 32. FIG.

  Further, as shown in FIG. 6A, the inner wall 36 f of the window frame opening 36 of the translucent substrate 32, corresponding to the position of the locking recess or step 44 of the translucent substrate 32, A bulging portion accommodating recess 46 is formed in the vertical direction of the translucent substrate 32.

Further, as shown in FIG. 6B, the locking recess or step 44 of the translucent substrate 32 is
It can also be formed on the entire periphery of the window frame opening 36 on the back surface of the translucent substrate 32.
Furthermore, as shown in FIG. 6C, it is of course possible to provide only the locking recess or step 44 and omit the bulging portion accommodating recess 46.

  Thus, as will be described later, as shown in FIG. 12, the locking piece 42 of the window frame insertion support portion 38b is bent, and the locking portion 42a is turned into the locking recess of the translucent substrate 32. Or when accommodated in the step part 44, it is comprised so that the window frame insertion support part 38b and the bulging part 56 of at least one of the base end part of a latching piece may be accommodated.

  As shown in FIG. 1, the solar power generation device 22 includes a ring-shaped outer edge that is a non-power generation region and a ring-shaped center that is a small-diameter non-power generation region formed so as to surround the needle shaft 31 of the movement 20. Department. Moreover, it has four division parts which comprise the non-electric power generation area | region which forms the cross line formed so that these outer edge parts and a center part may be connected.

And four fan-shaped solar cells are formed in the part enclosed by these division parts.
Of these divided portions, a window frame opening 22a is formed at a position corresponding to the window frame opening 36 of the translucent substrate 32, and a movement below the window frame opening 22a. 20, a calendar display unit 34 is rotatably incorporated.

  In this case, the display panel 24 including the translucent substrate 32 having the window frame opening 36 is made of a translucent substrate made of a soft material or a brittle material, for example, a solar cell (solar cell). When used as a display panel placed above the solar power generation device, it is used in solar cell equipment such as a solar watch equipped with a solar power generation device and a desktop computer using the solar power generation device. In order to cause the power generation function of the solar power generation device disposed on the lower surface side thereof.

  Further, the thickness of the translucent substrate 32 constituting the display plate 24 is desirably 30 μm to 1000 μm. If the thickness is within such a range, for example, when used as a display plate for a wristwatch. In order to reduce the thickness of the timepiece, even if the thickness of the light-transmitting substrate 32 is reduced, it can be processed without lowering the mechanical strength. Further, since the thickness of the translucent substrate 32 is too thick, it is possible to indicate an accurate time without the timepiece of the timepiece swinging, and the thickness of the timepiece itself can be made compact.

  Furthermore, if the thickness of the translucent substrate 32 is in such a range, for example, when used as a display plate of solar equipment such as a solar watch display plate, the light transmittance does not decrease, Light of a wavelength that contributes to power generation can be transmitted, the driving power of the devices can be secured, and a cross line or a deep purple color that is a boundary line of the solar cell disposed below the display panel 24 Can be removed so that the color of the solar cell is not visible.

The translucent substrate 32 may be formed by combining the above-described soft material and brittle material in a planar manner or in multiple layers.
Further, the soft material constituting the translucent substrate 32 is not particularly limited, and for example, synthetic resin, paper, cloth, or the like can be used. Further, the brittle material constituting the translucent substrate 32 is not particularly limited. For example, cloisonne, ceramics such as glass, shells such as white butterfly shells, and the like can be used.

  On the other hand, as a material constituting the window frame member 38, for example, a metal material such as gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or an alloy thereof is employed. For example, alloys such as titanium alloy, stainless steel, and tantalum carbide may be employed.

Below, the process of assembling the display board 24 comprised in this way is demonstrated based on FIGS.
5 is a perspective view of the translucent substrate 32 viewed from the back surface, FIG. 6 is a partially enlarged perspective view of FIG. 5 viewed from the back surface of the translucent substrate 32, and FIG. 7A is a window frame member 38. FIG. 7B is a partially enlarged view seen from the direction A of FIG. 7A, and FIG. 8 is a translucent view of the window frame member 38. FIG. 9 is a partially enlarged cross-sectional view illustrating a state in which the window frame member 38 is inserted into the window frame opening 36 of the translucent substrate 32, and FIG. 10 is a window frame. FIG. 11 is a perspective view of the fixing jig 48, and FIG. 12 illustrates a state in which the window frame member 38 is attached to the translucent substrate 32. 13 is a partially enlarged cross-sectional view of FIG. 12, and FIG. FIG. 15 is a partially enlarged view when viewed from the rear surface side of FIG. 15, in which the window frame fixing agent 40 is applied to the notch 38 d in a state where the window frame member 38 is inserted into the window frame opening 36 of the translucent substrate 32. It is a partial expanded sectional view explaining the state provided.

  First, as shown in FIG. 7 (a), the corners of the outer peripheral 3 o'clock direction and the 9 o'clock direction of the distal end portion 38c of the window frame insertion support portion 38b of the window frame member 38 are chamfered at an angle of approximately 45 degrees. A portion 38d is formed.

  Further, as shown in FIG. 7 (b), the window frame member 38 is spaced apart from the tip end portion 38c of the window frame insertion support portion 38b by two regular intervals in the 6 o'clock direction and the 12 o'clock direction. A locking piece 42 protruding from the rear surface side of the frame member 38 is formed.

  On the other hand, as shown in FIG. 5 and FIG. 6, on the back side of the transparent substrate 32 constituting the display panel, around the back surface of the window frame opening 36, at a position corresponding to the locking piece 42. A concave portion or step 44 is formed on the inner wall 36f of the window frame opening 36 of the transparent substrate 32 corresponding to the position of the locking concave portion or step 44 of the transparent substrate 32. A bulging portion accommodating recess 46 is formed in the vertical direction of the conductive substrate 32.

  By providing the bulging portion accommodating recess 46 in this manner, when the window frame member 38 is fixed to the display panel, the translucent substrate 32 can be fixed without causing distortion. For this reason, there are no restrictions on the material and specifications of the display board, and the design variations are expanded.

Then, as indicated by the arrows in FIG. 8, the window frame insertion support portion 38b of the window frame member 38 is inserted so as to pass through the window frame opening portion 36 of the translucent substrate 32 constituting the mounting through hole. To do.
In this state, as shown in FIG. 9, the flange frame portion 38 a of the window frame member 38 is locked to the upper surface of the outer periphery of the window frame opening 36 of the translucent substrate 32, and the window frame member 38 is moved downward. It is designed to prevent falling out.

  In the case of this embodiment, the locking pieces 42 that protrude from the rear surface side of the window frame member 38 are formed in the 6 o'clock direction and the 12 o'clock direction so as to be spaced apart from each other by two regular intervals. The formation position, the number, and the like of the stop pieces 42 are not particularly limited. For example, the stop pieces 42 are provided at 3 o'clock direction and 9 o'clock direction, for example, formed over the entire outer periphery of the front end portion 38c of the window frame insertion support portion 38b. It is also possible to do.

Therefore, it is only necessary to form the locking recess or step 44 and the bulging portion receiving recess 46 of the translucent substrate 32 in accordance with the arrangement of the locking pieces 42.
Further, in this embodiment, the cutout portion 38d is formed by chamfering the corners of the outer peripheral 3 o'clock direction and the 9 o'clock direction of the distal end portion 38c of the window frame insertion support portion 38b, but the present invention is not limited to this. However, although not shown, for example, a notch may be formed by chamfering the corners of the entire outer periphery of the distal end portion 38c of the window frame insertion support portion 38b, and only in the 6 o'clock direction and the 12 o'clock direction. It is also possible to form them partially or even partially in these directions.

  Next, as shown in FIG. 10, the projecting portion 50 formed on the fixing jig 48 from the lower surface (back surface) side of the translucent substrate 32 using the fixing jig 48. The member 38 is fitted into the window opening 38g.

  In this state, as shown in FIG. 11, the positioning member 52 formed so as to protrude from the central portion of the fixing jig 48 is inserted into the needle shaft 31 formed at the center of the translucent substrate 32. The translucent substrate 32 is positioned by fitting in the shaft hole 32a.

  Therefore, in this state, the window frame member 38 is fixed by the projecting portion 50 formed on the fixing jig 48 and the translucent substrate 32 is positioned and the translucent substrate 32 is positioned. The substrate 32 is held in a slightly movable state.

  Further, a taper pressing surface 54 is formed on the fixing jig 48 at a position corresponding to the locking piece 42 protruding from the rear surface side of the window frame member 38. As shown in FIGS. 10 to 13, the taper pressing surface 54 is formed so as to incline downward toward the outside, and the angle α formed with the horizontal plane is the bending of the locking piece 42. Considering the effect, an angle of 5 ° to 15 ° is desirable, and an angle of 10 ° is desirable.

In this state, as shown by the arrow in FIG. 10, the fixing jig 48 is pressed toward the window frame member 38 inserted and arranged in the window frame opening 36 of the translucent substrate 32.
As a result, as shown in FIGS. 12 and 13, the locking piece 42 of the window frame insertion support portion 38 b of the window frame member 38 is bent along the tapered pressing surface 54 of the fixing jig 48. Thus, the locking portion 42 a of the locking piece 42 is accommodated in the locking recess or step 44 of the translucent substrate 32.

Accordingly, the window frame member 38 can be fixed to the window frame opening 36 of the translucent substrate 32.
At this time, as shown in FIG. 13, light is transmitted to the inner wall 36 f of the window frame opening 36 of the translucent substrate 32 corresponding to the position of the locking recess or step 44 of the translucent substrate 32. Since the bulging portion accommodating concave portion 46 is formed in the vertical direction of the conductive substrate 32, the locking piece 42 of the window frame insertion support portion 38b is bent as shown in FIG. When being accommodated in the locking recess or step 44, the window frame insertion support 38b and the bulging portion 56 of at least one of the proximal end portions of the locking pieces are accommodated.

In FIG. 13, for the sake of convenience, a case where the bulging portion 56 is formed in the window frame insertion support portion 38b is shown.
With this configuration, the window frame insertion support portion 38b of the window frame member 38 is inserted into the window frame opening 36 of the translucent substrate 32, and the locking piece of the window frame insertion support portion 38b is inserted. The window frame member 38 is easily and firmly fixed to the window frame opening 36 of the display panel by bending the 42 and accommodating it in the locking recess or step 44 of the translucent substrate 32. Can do.

  Therefore, even when the substrate constituting the display panel is made of a soft material, no load is applied to the substrate, so that distortion occurs around the window frame member of the substrate, or plastic deformation does not occur. In addition, the appearance of the display board is not impaired.

Further, even when the substrate constituting the display panel is made of a brittle material, no load is applied to the substrate, so that cracks are not generated or damaged around the window frame member 38 of the substrate, There is no chipping, and the aesthetic appearance of the display board is not impaired.

  Therefore, even if the substrate itself is elastically deformed by an impact load, the window frame member 38 does not fall off the substrate, and the window frame member 38 can be firmly fixed to the display plate without applying a large mechanical load to the substrate. It is possible to provide a display panel which is excellent in strength, has a beautiful appearance, and has a high-class feeling.

  Further, when the locking piece 42 of the window frame insertion support portion 38b is bent and accommodated in the locking recess or step 44 of the display panel, the window frame insertion support portion 38b and the locking piece 42 Since at least one of the bulging portions 56 of the base end portion is accommodated, no load is applied to the substrate, so that distortion does not occur around the window frame member 38 of the substrate, and the plasticity does not change. There is no case of deformation, no cracks occur, no damage is caused, and the appearance of the display panel is not impaired.

  Further, while fixing the window frame member 38 in this manner and holding the display panel in a movable state, the locking piece 42 of the window frame insertion support portion 38b is bent so that the window frame member 38 is By fixing to the window frame opening 36 of the display panel, the window frame member 38 does not move when being fixed, so that the window frame member 38 is obliquely distorted to the window frame opening 36 of the display panel. The window frame member 38 can be fixed at a predetermined position without being fixed, and it is possible to provide a display panel that is excellent in strength, good in appearance, and has a high-class feeling.

  Further, by using the fixing jig 48 having the protruding portion 50 fitted in the window opening 38g of the window frame member 38 in this way, the protruding portion 50 is placed in the window opening 38g of the window frame member 38. By fitting into the window frame member 38, the window frame member 38 can be reliably fixed at a predetermined position.

  Accordingly, since the window frame member 38 does not move when the window frame member 38 is fixed, the window frame member 38 is not fixed to the window frame opening 36 of the display panel in a state where the window frame member 38 is obliquely distorted. It is possible to provide a display panel that is excellent in strength, good in aesthetics, and has a high-class feeling.

  Furthermore, the taper pressing surface 54 formed on the fixing jig 48 is pressed by pressing the fixing jig 48 toward the window frame member 38 inserted through the window frame opening 36 of the display board. Thus, the locking piece 42 of the window frame insertion support portion 38b is securely bent and accommodated in the locking recess or step 44 of the display panel, and the window frame member 38 is securely fixed at a predetermined position. can do.

  Further, since the display panel is positioned by the positioning member 52 formed on the fixing jig 48 as described above, the window frame member 38 can be fixed at a predetermined position of the window frame opening 36 of the display panel. In addition, it is possible to provide a display panel that is excellent in strength, good in appearance, and has a high-class feeling.

  Thus, after fixing the window frame member 38 to a predetermined position of the window frame opening 36 of the display panel, the window frame insertion support portion of the window frame member 38 is then used as shown in FIGS. For example, a window frame fixing agent 40 such as an adhesive is applied to the notch 38d formed in 38b by screen printing. The window frame fixing agent 40 is cured by heating to the curing temperature of the window frame fixing agent 40, and the window frame member 38 and the translucent substrate 32 are bonded and fixed.

In this embodiment, an adhesive that is cured by heating is used as the window frame fixing agent 40. However, the present invention is not limited to this. For example, an adhesive or laser that cures by evaporating moisture is used. An adhesive that cures when irradiated, an anaerobic adhesive that cures when air is blocked, an ultraviolet curable adhesive that cures when irradiated with ultraviolet rays, and the like can be used.

  As described above, when the window frame fixing agent 40 such as an adhesive is applied to the notch portion 38d, the window frame fixing agent 40 easily enters the contact surface between the window frame member 38 and the window frame opening 36, and is strong and simple. The window frame member 38 and the translucent substrate 32 can be bonded and fixed to each other.

  With this configuration, the translucent substrate 32 and the window can be obtained simply by applying the window frame fixing agent 40 to the cutout portion 38d formed in the window frame insertion support portion 38b of the window frame member 38 and heating it. The frame member 38 can be easily and firmly fixed.

In this embodiment, as shown in FIG. 14, when the window frame fixing agent 40 such as an adhesive is applied, the window frame fixing agent 40 is applied to the four corners of the window frame member 38. A portion 38f where the notch 38d is not formed is also applied. This makes it easier for the window frame fixing agent 40 to enter the contact surfaces of the window frame fixing agent 40 and the window frame opening 36 at the four corners of the window frame member 38, and more firmly the window frame member. 38 and the translucent substrate 32 can be bonded and fixed.
(Example 2)
FIG. 16 is a partially enlarged cross-sectional view similar to FIG. 15 in a state where the window frame member is fixed and assembled to the display board of another embodiment of the present invention.

The display board 24 of this embodiment has basically the same configuration as that of the display board 24 shown in FIGS. 1 to 10, and the same reference numerals are given to the same members, and a detailed description thereof is given. Is omitted.
In the display panel 24 of this embodiment, as shown in FIG. 16, a diffusion layer 33 is formed on the back surface of the translucent substrate 32 constituting the display panel 24. Thus, by providing the diffusion layer 33, light diffusion occurs when the reflected light from the solar cell 23 passes through the diffusion layer 33, so that the deep purple color of the solar cell 23 is almost erased and is not visually recognized. Further, when the reflected light of the solar cell 23 is diffused by the diffusion layer 33, a part of the diffused light is emitted toward the solar cell 23 and is incident on the solar cell 23 again. For this reason, the utilization efficiency of light increases and can contribute to power generation effectively.

  Also in this embodiment, the window frame fixing agent 40 such as an adhesive is applied to the notch 38d formed in the window frame insertion support portion 38b of the window frame member 38. The fixing agent 40 does not flow. For this reason, since the window frame fixing agent 40 does not flow into the diffusion layer 33 and the window frame fixing agent 40 is not visible from the surface of the display plate 24, a display panel with a good aesthetic appearance can be provided.

  In the above embodiment, the window frame member 38 has two window openings 38g. However, the number, shape, size, and arrangement position of the window openings 38g are particularly limited.
