Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a light emitting display device capable of displaying planar light emission.

[Background Art] Conventionally, there have been light-emitting display devices that utilize the edge light effect, but the display expression is only monotonous.

[Purpose of the invention] The object of the invention is to provide a light-emitting display device that allows light-emitting displays to be confirmed from both sides and that can perform different expressions of light-emitting displays on the same plane.

[Disclosure of the invention] Fig. 1 shows an embodiment of the invention, in which the device of this embodiment is formed by stacking two flat plates 1A and 1B made of transparent acrylic or glass.
As shown in FIG. 2, A and 1B have light emitting surfaces 2A and 2B with uneven surfaces formed by sandblasting.
The light emitting surfaces 2A and 2B are formed in a negative and positive relationship with each other. In other words, in the embodiment, the light emitting surface 2A and the plane plate 1 are symmetrical with respect to the center line formed on the plane plate 1A.
B has the same shape as the non-light emitting surface, and conversely, the flat plate 1B
The left-right symmetrical light-emitting surface 2B formed in is the same shape as the non-light-emitting surface of the flat plate 1A. The two flat plates 1A and 1B are then bonded together, and light from the light sources 3 separately provided corresponding to the flat plates 1A and 1B is introduced from the respective end faces to illuminate the respective light emitting surfaces 2A and 2B. The effect makes it shine.

Figures 3a to 3c show the state of the light emitting display,
Figure a shows a case in which light is introduced only into the flat plate 1A, and in this case, a luminescent display of a human pattern by the light emitting surface 2A can be seen from both sides of the device.

The figure also shows a case where light is introduced only into the flat plate 1B, and in this case, a silhouette of a human figure can be seen from both sides of the device due to the light emitting surface 2B.

Furthermore, FIG.
Since both of them emit light, the entire device is in a state of emitting light, and the pattern display becomes invisible.

Incidentally, by changing the color of the light introduced into each of the flat plates 1A and 1B, a change can be obtained by a combination of colors. The light emitting surface may be formed by sandblasting as follows. In other words, an uneven surface is formed on the entire surface of a flat plate by sandblasting, and then transparent ink is applied to unnecessary surfaces using a method such as silk screening to obtain the desired light-emitting surface pattern.

[Effects of the invention] The present invention stacks a plurality of light-transmitting flat plates to form an arbitrarily shaped light-emitting surface consisting of an uneven surface that produces an edgelight effect on each plane, and allows light to be emitted separately from the end face of each flat plate. Since each light emitting surface is made to emit light arbitrarily, a variable light emitting display can be performed on the same plane.Moreover, with the above-mentioned configuration, the display can be confirmed from both sides. By stacking two flat plates with negative and positive patterns on the light emitting surfaces,
By using one or both of the flat plates that introduce light, the pattern can become a silhouette or a glowing pattern.
Furthermore, a variable display effect can be obtained in which the entire surface is illuminated and the pattern is no longer visible.
