Problems solved by technology

[0004] However, as in Patent Document 1 figure 1 As shown, the light point display requires different substrates with multiple light sources arranged side by side
Therefore, the number of parts is large and the assembly process is complicated
In addition, in the dot-type display, it is necessary to arrange the light source with high precision with respect to the end surface of the light guide plate on the narrow side, but there is a problem that it is difficult to assemble with high positional accuracy, and the positioning operation is time-consuming, resulting in low productivity.

Embodiment Construction

[0070] based on Figure 1 to Figure 29 Embodiments of the present invention will be described.

[0071] The first embodiment is applicable to the case of a display device with conversion function, such as Figure 1 to Figure 7 As shown, the display device is composed of a first display panel 10 , an electrode panel 20 , a second display panel 30 and a cover 40 which function as a substrate.

[0072] The first display panel 10 may be a molded product made of transparent acrylic resin or polycarbonate resin, and may be a flexible elastic body. The first display panel 10 is provided with a storage recess 12 and a storage recess 13 one step lower than the storage recess 12 in an annular rib 11 formed on the outer peripheral portion of one surface thereof. The first display panel 10 uses the bottom surface of the storage recess 12 as a first display portion 14 . Additionally, if Figure 5 As shown, a plurality of minute dimples 99 that are difficult to be recognized by human ey...

Abstract

A display unit which can be simply assembled with a high assembling precision, is high in productivity, and requires fewer components and assembling man-hours. A transparent electrode sheet (20) is held between two transparent display sheets (10, 30). Lights from first and second LEDs (25, 26) respectively disposed on the front and rear surfaces of the electrode sheet (20) are allowed to enter the side edge surfaces of the transparent display sheets (10, 30), and are reflected off many fine dimples provided on one surface of each of the transparent display sheets (10, 30) to enable uniform displaying or displaying for us to be able to visually recognize patterns such as characters, symbols and graphics.

Description

technical field [0001] The invention relates to a display device, in particular to a display device with conversion function. Background technique [0002] Conventionally, as a display device, for example, there is a dot-type display in which a plurality of light-transmitting light guide plates are arranged side by side, and a plurality of reflection points composed of microscopic recesses are formed, and a light source is arranged on one side surface. A plurality of displays are displayed simultaneously or alternately (see Patent Document 1). [0003] Patent Document 1: (Japanese) Patent No. 3503608 [0004] However, as in Patent Document 1 figure 1 As shown, the dot-type display requires different substrates with multiple light sources arranged side by side. Therefore, the number of parts is large and the assembly process is complicated. In addition, in the dot-type display, it is necessary to arrange the light source with high precision on the narrow side end surface ...
