Description

  The present invention relates to signboards, signs, and information boards, and more specifically, signboards in facilities used by many people such as station buildings, underground malls, hotels, shopping malls, movie theaters, amusement facilities, public facilities, school buildings, and the like. , Visual indicators installed as signs, information boards, etc., instantly switch the visual display upon reception of a radio signal or electrical line signal, and alternately display different visual displays, thereby 1). A disaster prevention display structure capable of transmitting information such as guidance information and messages in the event of a disaster in real time, and 2). The present invention relates to an advertisement display structure capable of effectively expressing a sales promotion display and an image, and more particularly to a visual display structure capable of three types of display by one unit.

  Recently, evacuation guide plates using materials that store phosphorescent light in the dark have been installed everywhere on the floors of underground stations, communication passages, concourses, stairs, and other corners of walls. Such evacuation guide plates and signs are mainly displayed as an arrow mark or a symbol mark of an evacuation exit. In particular, the underground station building concourse and the walls of the underground street are used as effective advertising spaces, and large advertising signs are installed, but if these large advertising signs can serve as an evacuation guide during power outages, It will be possible to construct facilities with enhanced disaster prevention measures. For example, Japanese Patent Application Laid-Open No. 2009-186526 (Patent Document 1) discloses a display body in which a visual control layer is laminated on a light-transmitting flat base material as a display body that serves both as an advertising signboard and an evacuation guidance sign. In the sex control body, the visual display layer (A) is provided on the surface of the visual control layer, the visual display layer (B) is provided on the entire back surface, and the visual display layer (B) is the phosphorescent material containing part. And a multi-visual display structure composed of a phosphorescent material-free portion has been proposed. Japanese Patent Application Laid-Open No. 2008-170520 (Patent Document 2) includes a main sheet having a main design on the front surface, and a sub display unit having a sub design formed using a phosphorescent layer on the back side thereof. Is provided, and a small hole group is provided in a portion of the main sheet that overlaps the phosphorescent layer, so that only the main symbol of the main sheet is visible in a bright environment, and the sub symbol is visually recognized through the small hole group in a dark environment. A display has been proposed.

  These display bodies can display two types, and can store and switch to a hidden symbol such as a visual display layer (B) or a sub-symbol by emitting phosphorescent light at night or during a power failure. However, there are many places that are bright even at night due to car lights and store lighting in the city, and in underground shopping areas, emergency lights with battery lights are installed in the event of a power failure. Therefore, the environment that brings about the darkness where the original phosphorescent light emission effect is exhibited is limited to places where people do not enter much, such as in the basement of buildings, etc. In such places, installation effects as signboards, signs, and guide boards are effective. Since it was not obtained, there was not much need for installation of a display body that used both an advertising billboard and an evacuation guide sign. Therefore, under a light source, it is recognized as a signboard, a sign, a guide board, etc., but is a heterogeneous visual display structure that can display a guidance guidance display and a message in the dark. In a busy place, the visual display can be switched instantly, and different visual displays can be displayed alternately, thereby 1). A disaster prevention display structure capable of transmitting information such as guidance information and messages in the event of a disaster in real time, and 2). There has not yet been a visual display structure that can display three types of displays, such as an advertisement display structure that can effectively express sales promotion displays and images.

It is formed on the transparent sheet or the back side of the transparent sheet by any one of silk screen printing, transfer printing, and marking film sticking, and this transparent sheet with the second printed display layer is placed on the third printed display layer. Thus, replacement with other second print display layers can be freely performed. Further, the second printed display layer has a total light transmittance (JIS K7375) of 35 to 75%, so that the third printed display layer disposed on the electroluminescent element layer due to the high-luminance emission of the electroluminescent element layer. Is transmitted through the second print display layer (light transmissive print portion), and the third print display layer can be highlighted regardless of the presence of the second print display layer. Therefore, the light emission luminance of the electroluminescence element layer must be larger than the light emission luminance of the second print display layer. Specific examples of the transparent sheet include polyester sheets such as polyethylene terephthalate, boribylene terephthalate, and polynaphthalene terephthalate, acrylic sheets, polycarbonate sheets, polystyrene sheets, polyethylene sheets, polypropylene sheets, and semi-rigid polyvinyl chloride sheets. In the case where replacement with another second print display layer is not required, the second print display layer may be provided directly on the third print display layer. The second print display layer may be constituted only by a printing unit containing phosphorescent phosphor particles, but preferably a printing unit A containing phosphorescent phosphor particles and a printing unit not containing phosphorescent phosphor particles. B, and the color difference ΔE (JIS Z8729) between the printing part A and the printing part B is 10 or less, particularly 6 or less. When the color difference ΔE exceeds 10, the outline of the second print display layer may be raised by visual observation from the first print display layer, interfere with the appearance, and may overlap the first print display layer. In order to make the color difference ΔE 10 or less, for example, if the color of the printing unit A is a bluish green color, the printing unit B is also toned and adjusted as a bluish green color. The phosphorescent phosphor particles are preferably light translucent particles such as green phosphorescent light emitting particles and blue phosphorescent light emitting particles. If the light-impermeable luminescent particles are used, the phosphorescent light emission luminance is inferior, and the display of the third printed display layer may be disabled. As blue-based phosphorescent phosphor particles, 0.001 to 10 mol% of a divalent metal aluminate (for example, strontium aluminate) base crystal was added to a divalent metal using a rare earth element as an activator.

These phosphorescent phosphor particles preferably have an average particle size of 10 μm to 100 μm, particularly those having an average particle size of 10 μm to 35 μm for silk screen printing. The second printed display layer is a light-transmitting printed layer having a total light transmittance (JIS K7375) of 35 to 75%, and the phosphorescent phosphor particles occupying the printing part containing the phosphorescent phosphor particles are 25 to 75 mass%. Thus, it is necessary that the phosphorescent phosphor particles themselves having an average particle diameter of 10 μm to 100 μm themselves are semi-transparent. In addition, in order to make the total light transmittance (JIS K7375) of the second printed display layer 35 to 75%, the silk screen printing ink uses phosphor as a transparent to emulsion-based synthetic resin and stores light in the solution. A paint in which phosphor particles are uniformly dispersed is used. The synthetic resin used for the binder can be UV cured by using an ultraviolet curable resin. In addition, as a marking film form, a liquid in which phosphorescent material particles are uniformly dispersed in a non-colored thermoplastic resin composition such as a pasty polyvinyl chloride resin is formed in a sheet form having a thickness of 0.1 mm to 0.5 mm. These are formed with a colorless and transparent adhesive applied, or without adhesive, and these can be used as a part of the cut and cut letters by a computer cutting machine to form the second printed display layer.

The ink used for printing and the marking film are preferable from the aesthetic viewpoint of the multi-purpose visual display structure from which light-transmitting ones can be obtained, but when using the printing part or marking film attachment as a silhouette part, the ink, and The marking film may be light impermeable. A combination of a light-transmitting ink and a light-impermeable marking film may also be used. Such a third printed display layer is 1) provided directly on the electroluminescence element layer and obtained by integrating with the electroluminescence element layer, 2) on a transparent sheet having a thickness of 0.05 mm to 1.0 mm, Alternatively, it is provided on the back surface of the transparent sheet and is disposed on the electroluminescence element layer with the transparent sheet interposed therebetween, and the transparent sheet and the electroluminescence element layer are not bonded.

An organic transparent conductive film is particularly preferable in the multi-visual display structure of the present invention because the function as a surface light emitting element may be impaired due to micro cracks caused by bending or bending. By using an organic transparent conductive film as the transparent electrode, it is possible to prevent the transparent electrode from cracking due to stress deformation of the multi-visual display structure of the present invention. Examples of such an organic transparent conductive film include polythiophene derivatives such as polythiophene, poly3,4-ethylenedioxythiophene (PEDOT), poly3,4-ethylenedioxythiophene / polystyrene sulfonic acid (PEDOT / PSS), A conductive polymer film such as polyaniline and polyacetylene is formed to a thickness of about 1 μm to 3 μm.

  Hereinafter, the multi-visual display structure of the present invention will be specifically described. FIG. 1 is a diagram showing an example of the appearance of the multi-visual display structure (1) of the present invention in a normal state (electroluminescence element OFF). The first printed display layer (4) is formed on the surface of the visual control layer (3). The character “STAR” is provided by means such as gravure printing, screen printing, ink jet printing, transfer printing. Normally, the first print display layer (4) displays a guide map of a park or public facility, and a corporate advertisement, but for the sake of illustration, it is simplified to only “STAR”. The visual control layer (3) is composed of a substantial part (3aa) and a perforated part (3ab). These punched portions (3ab) are partially lacked in printing for displaying a part of the character structure of “STAR” in the first print display layer (4), and the punched portion (3ab) has a second portion. A part of the printed display layer (5) (a printing part containing phosphorescent phosphor particles and a printing part not containing phosphorescent phosphor particles) is exposed and observed. Alternatively, when the multi-visual display structure of the present invention has the contrast adjusting layer (8) between the light-transmitting planar base material (2) and the second printed display layer (5), the perforated part (3ab) Is in a state in which the contrast adjusting layer (8) is exposed and observed. The multi-visual display structure (1) has four edges fixed by a frame (11).

  FIG. 2 is a diagram showing an example of the appearance of the multi-visual display structure (1) of the present invention shown in FIG. 1 when operated in the dark (electroluminescence element OFF). It represents a dark place observation state at the time. On the surface of the visual control layer (3), “hexagonal star shape” of the second printed display layer (5) is displayed as dots by phosphorescent emission, and the characters “STAR” of the first printed display layer (4) are not observed. . Usually, an evacuation guidance symbol mark or a corporate advertisement is displayed on the second print display layer (5), but for simplification of the drawing, only a “hexagonal star” figure is simplified. What is displayed on the perforated part (3ab) of the visual control layer (3) and observed in the form of dots is a part of the second printed display layer (5) (printing part containing phosphorescent phosphor particles and phosphorescent phosphor particles) (Printing part not including). The “hexagonal star shape” of the second print display layer (5) is configured by light emission and / or light-shielding of a printing part containing phosphorescent phosphor particles and / or light transmission or light shielding of a printing part not containing phosphorescent phosphor particles. Is done. The second printed display layer (5) is a “hexagonal star” formed by silk screen printing, transfer printing, and marking film sticking, and a portion that does not contain phosphorescent phosphor particles and has a light shielding property. Emphasizes “hexagonal” shadows as dark or low-luminance light emitting parts. It is not always necessary to add a shading. For example, a “hexagonal star” having a blue-green color with high-luminance phosphorescent light emission and a background margin colored in yellow is usually used for the entire surface of the second printed display layer (5). Utilized light emission display is preferable.

  FIG. 3 is a diagram showing an example of the appearance of the multi-visual display structure (1) of the present invention shown in FIG. 1 when operated in the dark (electroluminescence element ON). Due to the light emission of the luminescence element layer (7), only the Chinese character of “star” in the third printed display layer (6) is observed in the aggregate of light emitting dots. Normally, an evacuation guidance symbol mark or a corporate advertisement is displayed on the third printed display layer (6), but for the sake of illustration, it is simplified to only the Chinese character “star”. It is a part of the third print display layer (6) that is displayed on the perforated part (3ab) of the visual control layer (3) and observed in the form of dots. The “STAR” characters on the first print display layer (4) are difficult to recognize in the dark, and the “hexagonal star” on the second print display layer (5) is also difficult to recognize. This is because the second printed display layer (5) has a light transmittance of 35 to 75% of the total light transmittance (JIS K7375), and the emission brightness of the third printed display layer (6) is the second printed display layer ( This is because it is larger than the light emission luminance of 5). Therefore, since the multi-visual display structure (1) of the present invention has a particularly high emission luminance of the electroluminescence element layer (7), the third printed display layer ( 6) It is excellent in the eye-catching effect because it is displayed vividly, and the second printed display can be achieved by repeating the “ON / OFF” operation for a short time to emit light from the electroluminescence element layer (7) in the dark. Not only the flash lighting of the layer (5) and the third print display layer (6) is produced, but the light emission of the electroluminescence element layer (7) that transmits the second print display layer (5) is the second print display. By acting on the light storage of the layer (5), it is possible to store light for a long time in the dark. Such a crowd effect is extremely effective for evacuation guidance, alerting, and message transmission in the event of a disaster. The power supply (power ON) to the inorganic electroluminescence element layer (7), that is, the means for displaying the third print display layer (6) is a remote operation such as a radio signal or an Internet line signal, or a multi-visual display structure. By self-lighting (flash lighting program) by specific shaking detection by seismic intensity sensor attached to (1).

(Red) "was clearly recognized, the presence of the star mark (hexagonal double star) in the second printed display layer, and the letter" star "in the third printed display layer were not fully recognized. Next, when the room light was turned off, the letters “STAR” on the first print display layer disappeared, and suddenly the phosphorescent light emission in the form of a star mark (hexagonal double star) on the second print display layer appeared in the visual control layer. Appeared through. This second printed display layer is composed of a “star mark” (hexagonal star double) made of phosphorescent phosphor particles-containing ink and a star mark margin made of ink containing no phosphorescent emitter particles. Only the perforated sheet, which is the visual control layer, is displayed as an aggregate of dot light emission through the perforated sheet (circular hole with a diameter of 2 mmφ). It was displayed in a clear star shape by becoming a dark part that does not. Furthermore, when the inorganic electroluminescence element layer was made to emit light at 350 cd with an AC 200 V, inverter and a frequency of 1000 Hz, the “star mark” (hexagonal double star) of the second printed display layer disappeared. The light emission of the letter “star”, which is the printed display layer, appeared through the visual control layer. This third printed display layer is displayed as a dot-like aggregate by transmission light emission from the aperture portion (circular hole with a diameter of 2 mmφ) of the perforated sheet, and the hidden print portion of the third print display layer is an aperture portion (with a diameter of 2 mmφ) A clear “star” character shape was displayed because the circular hole was a dark part where no dots were emitted. When observed closely, the first printed display layer was recognized by the high-intensity light emission of the inorganic electroluminescent element layer, but the presence of the first printed display layer was not noticed when observed several meters away. Met. Furthermore, when the room lighting is turned on in this state, the third print display layer appears on top of the first print display layer, but the first impression is the first impression because the emission brightness of the third print display layer is high.

When the display structures obtained in Examples 2 to 23 were hung on indoor walls and observed under illumination, the letters “S (blue)”, “T (yellow)”, “A” of “STAR” of the first print display layer were observed. (Green) and "R (red)" are clearly recognized, the presence of the star mark (hexagonal double star) in the second printed display layer, and the letter "star" in the third printed display layer are completely Not recognized. Next, when the room light was turned off, the letters “STAR” on the first print display layer disappeared, and suddenly the phosphorescent light emission in the form of a star mark (hexagonal double star) on the second print display layer appeared in the visual control layer. Appeared through. This second printed display layer is composed of a “star mark” (hexagonal star double) made of phosphorescent phosphor particles-containing ink and a star mark margin made of ink containing no phosphorescent emitter particles. Only through the perforated sheet (circular hole with a diameter of 2 mmφ), which is the visual control layer, is displayed as an aggregate of dot emission (striped in Examples 3 and 16), and the star mark margin is open. The hole portion (circular hole with a diameter of 2 mmφ) became a dark portion where no dots were emitted, thereby displaying a clear star shape. Furthermore, when the inorganic electroluminescence element layer was made to emit light at 350 cd with an AC 200 V, inverter and a frequency of 1000 Hz, the “star mark” (hexagonal double star) of the second printed display layer disappeared. The light emission of the letter “star”, which is the printed display layer, appeared through the visual control layer. This third printed display layer is displayed as a dot-like aggregate by transmission light emission from the aperture portion (circular hole with a diameter of 2 mmφ) of the perforated sheet, and the hidden print portion of the third print display layer is an aperture portion (with a diameter of 2 mmφ). A clear “star” character shape was displayed because the circular hole was a dark part where no dots were emitted. In Example 13 and Example 14, by changing the third print display layer, the light transmissive printed portion emitted colored dots through the apertures of the visual control layer, thereby displaying a colorful “star” character. When observed closely, the first printed display layer was recognized by the high-intensity light emission of the inorganic electroluminescent element layer, but the presence of the first printed display layer was not noticed when observed several meters away. Met. Furthermore, when the room lighting is turned on in this state, the third print display layer appears on top of the first print display layer, but the first impression is the first impression because the emission brightness of the third print display layer is high. Three print display layers became the main, and after a few seconds, the first print display layer became the second impression. A similar test was conducted on the street. Inorganic electroluminescence element layers even in bright places with many street lamps, places with heavy traffic, crowded places in stores, neon signs and electric signs, etc. Because of its high light emission brightness, it is excellent in the effect of appealing the third print display layer while displaying the first print display layer. In particular, the light emission of the inorganic electroluminescence element layer is alternately turned ON / OFF every few seconds. Furthermore, the message of the third printed display layer was impressed vividly. Even more surprisingly, the multi-visual display structure of the present invention was vivid in the message of the third printed display layer even when used on a clear day. In particular, in the display structures of Examples 11 to 23, the second printed display layer and the third printed display layer are provided on the transparent PET film and arranged non-adheringly, thereby disassembling the frame of the multi-visual display structure. The second printed display layer-forming PET transparent film and / or the third printed display layer-formed PET transparent film is removed, and the other second printed display layer-formed PET transparent film and / or the other third printed display layer-formed PET transparent film is removed. Since the display can be changed easily and quickly by exchanging with the film, it is possible to effectively appeal a daily change service, a POP display, etc. for commercial use.
