Embodiment
For making those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
As shown in Figures 1 to 4, the present embodiment provides a kind of backlight assembly, and it comprises the first blooming piece 11, flexible adhesive tape 2, light guide plate 3.
Fig. 1 is the backlight assembly structural representation after being provided with the first blooming piece and flexible adhesive tape; Wherein, the first blooming piece 11 has towards the first surface of light guide plate 3.Preferably, this first blooming piece 11 is reflector plate.
Flexible adhesive tape 2 is attached to the edge of the first surface of the first blooming piece 11, and each lateral edges of first surface has flexible adhesive tape 2; And flexible adhesive tape 2 is preferably formed closed annular.
That is, as shown in Figure 1, in the edge of the first blooming piece 11 near light guide plate 3 one side, the flexible adhesive tape 2 of a circle is bonded with, to play the effect supporting light guide plate 3.Obviously, for playing better supporting role, therefore the flexible adhesive tape 2 of its each side edge preferably connects into an entirety, forms the annular closed.
Wherein, flexible adhesive tape 2 has body and adhesive layer, and its body is made up of the flexible material such as rubber, plastics, and its concrete material can be and comprises polyethylene terephthalate (PET), teflon, PVC etc.
The one-tenth-value thickness 1/10 of flexible adhesive tape 2 then should be greater than the thickness of other structures in backlight assembly except the first blooming piece 11 and value, it is usually preferred between 0.4mm to 0.6mm, such as, can select at 0.5mm.
As shown in Figure 2, light guide plate 3 is located on the first surface of the first blooming piece 11, and by flexible adhesive tape 2 around.
That is, as shown in Figure 2, light guide plate 3 is placed on the centre of the first blooming piece 11, and is arranged in the region irised out by flexible adhesive tape 2.Wherein, " light guide plate 3 by flexible adhesive tape 2 around " refers to that the position of light guide plate 3 is between the flexible adhesive tape 2 of each side, and it is not overlapping with flexible adhesive tape 2, simultaneously, also the thickness of tabula rasa 3 is instructed to be less than the thickness of flexible adhesive tape 2, namely the upper surface of light guide plate 3 lower than the upper surface of flexible adhesive tape 2, to ensure that display panel 9 contacts with flexible adhesive tape 2, but not should contact with light guide plate 3.
The backlight assembly of the present embodiment comprises flexible adhesive tape 2, and it can replace glue frame and play the effect supporting display panel 9, therefore no longer needs glue frame in its display device; Because flexible adhesive tape 2 thickness can be very thin, therefore it can be used in ultra-thin display showing device, and flexible adhesive tape 2 can be easy to be attached in advance on the first blooming piece 11, therefore installs easy and simple to handle.
Preferably, above backlight assembly also comprises: the lamp bar 4 being located at light guide plate 3 at least side, it is positioned at inside flexible adhesive tape 2, and is connected with flexible circuit board (FPC) 41, and flexible circuit board 41 is located at above flexible adhesive tape 2 at least partly.
Illustrate to be provided with a lamp bar, as shown in Figure 2 and Figure 4, light guide plate 3 side need be provided with lamp bar 4 using as its light source, and this lamp bar 4 also should be positioned at inside flexible adhesive tape 2; And lamp bar 4 is powered by flexible circuit board 41, therefore flexible circuit board 41 needs to pass above flexible adhesive tape 2, to connect extraneous power supply.
Certainly, the application's light guide plate is not limited to arrange a lamp bar and corresponding flexible PCB.Such as, two can be arranged.When two lamp bars are set, can need be provided with lamp bar 4 in light guide plate 3 side as the first lamp bar, at the offside arranging the first lamp bar, lamp bar be set as the second lamp bar, and flexible PCB corresponding to the second lamp bar is set.Wherein the second lamp bar and corresponding flexible PCB and the first lamp bar and corresponding flexible PCB 41 set-up mode similar, repeat no more here.
Preferred further, above backlight assembly also comprises: shading adhesive tape 5 as shown in Figure 3, it is located at above light guide plate 3 edge and flexible adhesive tape 2, and is at least bonded in flexible adhesive tape 2, and flexible circuit board 41 is at least partly between flexible adhesive tape 2 and shading adhesive tape 5.
That is, as shown in Figure 3, because light guide plate 3 marginal portion bright dipping is uneven, therefore need to be covered by shading adhesive tape 5, and shading adhesive tape 5 now is also bonded in flexible adhesive tape 2, thus flexible circuit board 41 is fixed between flexible adhesive tape 2 and shading adhesive tape 5, accurately to locate it.
Preferably, see Fig. 4, above backlight assembly also comprises: be located at the double faced adhesive tape 411 between flexible circuit board 41 and flexible adhesive tape 2.
That is, in order to better positioning flexible wiring board 41, therefore also double faced adhesive tape 411 can be set between itself and flexible adhesive tape 2, thus be bonded in flexible adhesive tape 2.
Preferably, above backlight assembly also comprises: at least one second blooming piece 12, and it is located at the side of light guide plate 3 away from the first blooming piece 11, and by flexible adhesive tape 2 around.
Preferred, the second blooming piece 12 comprises at least one in prismatic lens, lower prismatic lens, diffusion sheet.
That is, in light guide plate 3, also can be provided with other blooming pieces (the second blooming piece 12) such as prismatic lens, lower prismatic lens, diffusion sheet successively, and these second blooming pieces 12 are also all located at inside flexible adhesive tape 2, and upper surface is lower than the upper surface of flexible adhesive tape 2, so that flexible adhesive tape 2 contacts with display panel 9.
Concrete, as shown in Figure 4, when having the second blooming piece 12, but also some is bonded in the edge of the second blooming piece 12 to shading adhesive tape 5.
As shown in Figure 4, the present embodiment also provides a kind of display device, comprising:
Above-mentioned backlight assembly; And display panel 9, it contacts with the flexible adhesive tape 2 of backlight assembly.
That is, this display device comprises above backlight assembly, and display panel 9 is located at the side that backlight assembly is provided with flexible adhesive tape 2, it contacts with flexible adhesive tape 2 thus, thus flexible adhesive tape 2 can play the effect of similar glue frame, do not have glue frame in display device thus, it is convenient to realize ultrathin design, easy for installation.
Obviously, owing to having backlight assembly, therefore this display device is liquid crystal indicator, and display panel 9 should be display panels.Concrete, this display device can be any product or parts with Presentation Function such as mobile phone, panel computer, televisor, display, notebook computer, digital album (digital photo frame), navigating instrument, wearable device (as intelligent watch, watch etc.).
Be understandable that, the illustrative embodiments that above embodiment is only used to principle of the present utility model is described and adopts, but the utility model is not limited thereto.For those skilled in the art, when not departing from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement are also considered as protection domain of the present utility model.
