Description

[Detailed description of the invention] This invention is an inexpensive and colorful composite display device! Regarding ic.

Conventionally, as shown in Fig. 1, by laminating a self-luminous light-emitting diode α3C13 and a light-receiving liquid crystal display aS, a composite display fim has been created that can display a clear C2 display in both bright and dark places. It had been proposed, but still.

As shown in Figure 2, the font αI is displayed on the liquid crystal display.
11'j... similar to the shape d 2 L nail bar-shaped light emitting diodes + 13... Because of the structure in which 1 light emitting diode o3tta... is arranged, the font is a liquid crystal display -
Not only is it unnatural because it is too different from the font of 1 light emitting diode d'; Therefore, it was only a technical proposal, and in reality it was used instead of light emitting diodes.
It wasn't too much, but in this - case, the +4 circle is bright at night (the display is dark, so-called cut-out characters, which is not preferable).

Also, the color was the same.

This invention was made taking these (/J points into consideration).

The present invention will be described in detail below based on embodiments.

The reflective frame (3) has a shape in which the upper If1 open row is equal to the picture elements (9), (9), etc. of the liquid crystal display +5), and the arrangement is also similar. However, the picture elements of the reflective frame (31) and those of the liquid crystal display (5) do not necessarily have to match.
2.It depends on 1. As before, the LCD display is used in bright places, and the light emitting diode is used in dark places. This is because only the display on the liquid crystal display 1151 is intensified because the outline of the display on the display (5) becomes brighter.One light emitting diode f2+121... is approximately a cube with a side of -0.5. Diode+
When 21f2+... is turned on, the light is directed upward by the reflective frame (3) and the light diffusion sheet (4) is illuminated.

As described above, the present invention includes a substrate, a minute light emitting diode placed on the same line on the substrate, and an upward opening edge that surrounds the light emitting diode and imitates a display picture element. A reflective frame, a light diffusion note covering the upper part of the reflective frame, and a light diffusion sheet 62 are provided above the reflective frame.

The display pixels are approximately the same as the display pixels of the reflective frame, and because it is a composite display device equipped with a field-effect liquid sealed in a transparent container and a display device, the font can be freely selected and the colors are rich. Moreover, even if the display power is increased by 1, the price is low.

Name Composite Display Device 2, Claims 1) A substrate, a minute light emitting diode placed and fixed on the substrate, and a top opening edge surrounding the light emitting diode and imitating a display pixel, and placed on the substrate. a reflective frame arranged, a light diffusing sheet extending above the reflective frame, and an electric field effect device provided on the light diffusing sheet, with display picture elements substantially equal to display picture elements of the reflective frame, and sealed in a transparent container. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inexpensive and colorful composite display device characterized by having a liquid crystal display of the type shown in FIG. A composite display device has been proposed in which a light-emitting diode a'a and a light-receiving liquid crystal display Q51 are stacked to provide clear display in both bright and dark places. However, as shown in FIG. 2, because of the structure in which the bar-shaped light emitting diodes 0303... are arranged in a shape similar to the font Qlαl... on the liquid crystal display a9, the light emitting diodes a'aa' Not only is the font of a... so different from the font of liquid crystal display a9 that it is unnatural, but the light emitting diode 03Q3... requires a large crystal, and the liquid crystal display O! 9 and the light emitting diode and the light emitting diode 2... Since half mirror I was used in the darkness, it became extremely expensive, so it was just a technical proposal.
In reality, instead of light-emitting diodes, light pipes or surface light emitters such as electroluminescent materials were used to illuminate the liquid crystal display, but in this case, at night, the display was bright and the display was dark, with so-called cut-out characters. This was not desirable, and the colors were monotonous. The present invention has been made in consideration of these points, and the present invention will be explained in detail below based on an embodiment. Fig. 6 is a sectional view of a composite display device showing an embodiment of the present invention. is a substrate based on paper epoxy resin, paper phenolic resin, etc. f2+ (21... is a light emitting diode such as GaP, which is mounted and fixed on the substrate (1). (3) is a reflective frame made of a white resin molded product, etc., surrounding the light emitting diode +21f21... (4) is the light diffusion sheet that covers the surface of the reflective frame (3), and (5) is the liquid crystal display, and the conductive rubber (6) is placed on the substrate (1).
(6) is wired to the board (11) and fixed frame (fixed to the board (11) by force so that it is positioned directly above the reflective frame (3).
It is. (8) (8) are light emitting diodes (2
This is an integrated circuit that drives +(2+...) and the liquid crystal display (5), which operate alternately or simultaneously as necessary.The above-mentioned components will be explained in detail first. The container (5) is a twisted nematic type field effect liquid crystal (51) and two transparent electrode plates (52) (
52), and polarizing plates (56) and (55) are attached to the front and back sides, and the display font is, for example, a picture element (9
) 191... is combined into a mouth shape. - The tip of force ameliorating sheet (4) is a thin film of polyester resin coated with or kneaded with lucium carbonate, etc., but it may also be a thin layer of silver foil coated with vapor deposition or the like to form a thin layer of 10 to 10 amps. The upper opening edge of the frame (3) has a shape that is approximately the same as the picture elements 19, (9), etc. of the liquid crystal display (5), and the arrangement is also similar. However, the picture elements of the reflective frame (3) and those of the liquid crystal display (5) do not necessarily have to completely match those of the liquid crystal display (5). When driving exclusively with light-emitting diodes, slight differences in position and shape do not matter,
This is because when driving both under certain conditions, the outline of the display on the liquid crystal display (5) becomes brighter, so only the display on the liquid crystal display (5) is emphasized.
When the light emitting diodes +21+21... are turned on, the light is directed upward by the reflective frame (3) and the light diffusion sheet (4) is illuminated. As described above, the present invention includes a substrate, a minute light emitting diode placed and fixed on the substrate, and a reflective frame placed on the substrate by surrounding the light emitting diode and forming a top opening edge resembling a display pixel. and a light diffusion sheet that runs across the top of the reflective frame.
Since this is a composite display device that is provided on a light diffusion sheet, the display pixels are approximately equal to the display pixels of the reflective frame, and is equipped with a field-effect liquid crystal display sealed in a transparent container, the fonts etc. It is flexible, has rich colors, and is inexpensive even if the display is large. 4.
