Abstract

PURPOSE:To reduce the size of a device and to enable effective shielding of light by providing a pair of electrodes in the position facing the support of a light transmittable material having a space for filling and housing a liquid crystal. CONSTITUTION:A support 1 has parallel plates 3, 4 and a blocking plate 5 for regulating the space for filling and hermetically housing a liquid crystal 2. A pair of electrodes 6, 7 are provided to the plates 3, 4 and the liquid crystal 2 is activated to a light shieldable state when a voltage is impressed thereon. The light in the direction 8 is thus blocked and the device is usable as a blind, etc. The adjustment of the quantity of the transmitted light is accomplished by filling the liquid crystals 2a-2d into the discrete spaces for hermetic housing of plural layers consisting of plate bodies 3a, 4a, 9, 10, 11 and impressing a voltage to the electrodes 6a, 7a, 6b, 7b, 6c, 7c, 6d, 7d for the respective electrodes, thereby activating selectively the liquid crystals 2a-2d and making the same semi-light transmittable.

Description

[Detailed description of the invention] The present invention relates to a device using liquid crystal.

Typical prior art is so-called blinds or curtains. Such blinds and curtains are used, for example, to block direct sunlight. Blinds and curtains are relatively large, and it is desired that they be made more compact.

Particularly, when blinds and curtains are to be mounted on passenger vehicles such as heavy railway vehicles, automatic tombs, and airplanes, miniaturization is strongly desired.

Therefore, it is an object of the present invention to provide a device using a Y{{ product, which can achieve small I arsenic and can perform light shielding and the like.

Figure XifJIl is a partially cutaway perspective view of one embodiment of the water valve 4. The support l is liquid crystal 2f: full; J l,
The plate body 3 includes a pair of parallel plates 3.4 defining an airtight storage space, and a closing plate 5 for closing the storage space.
4 is made of a translucent material such as glass.

A pair of electrodes 6.7 are provided on the body 3.4 in contact with the liquid crystal in the storage space. By applying tar pressure to the electrodes 6 and 7, the liquid crystal 2 (1) is activated and enters a light-blocking state.Therefore, light in the direction of arrow 8 is blocked.
The function is achieved as a blind or curtain to block the incidence of direct sunlight. Moreover, it has quick response and can be operated remotely. This arrangement is compact compared to conventional blinds and curtains and can be advantageously used as windows in passenger vehicles such as automobiles, railroad vehicles, and airplanes.

K, which adjusts the amount of light transmitted, is a plate 3a made of a translucent material, as in the embodiment shown in FIG.

4a, 9, 10.11 (in this example, 4
) The liquid crystals 2a to 2d are filled between individually airtight storage chambers of the layers, and a voltage is applied to the pair of electrodes 6a, 7a; 6b, 7b; 6c, 7c; 6d, 7d in contact with each liquid crystal 2a to 2d. is applied to selectively activate the liquid crystals 23 to 2d.

The liquid crystals 23 to 2d become semi-transparent when activated, and therefore the number of liquid crystals 2a to 2d to be activated simultaneously may be selected in accordance with the desired amount of light transmission.

FIG. 3 is a perspective view of still another embodiment of the present invention,
Figures 4 and 5 are t7I + fold line IV-I in Figure 3.
They are sectional views seen from V and v-■, respectively. A plurality of storage spaces are formed side by side in one plane on the flat plate 13 made of a translucent material, and the storage space is formed by another flat plate made of a translucent material. 14 hermetically closed. Each storage space Ki is individually filled with LCD 15"1
I'm being turned away. A pair of opposing electrodes 16 are provided in contact with this liquid crystal 15 . Each electrode 16 is shaped like a strip and has a plane parallel to the direction in which the light travels. Paired electricity 4i 16
The Tjl pressure is applied to all of the 11 or 11 selectively for each pair, and f'LV is thereby completely blocked or transmitted 11
1 can be changed. According to this example, if i”L,
The total distance between the pair of electrodes 16 can be made softer. Therefore, it is possible to stably activate the liquid crystal, and the trap driving air pressure can be low.

FIG. 6 is a partially cutaway perspective view of an embodiment of the pond of the present invention, and FIG. 7 is a sectional view of the embodiment.

This embodiment can be used as an image display device such as a color television receiver.

From the front to the back, a flat liquid crystal means 18, a color member J 9
, a diffuser plate 20, and a fluorescent tube 21, which is energized by DC power and serves as a white light emitting means, are sequentially arranged.

In the liquid crystal means 18, parallel transparent FJI:1 electrodes 22, 23 are orthogonally spaced apart, as shown in FIG.

The liquid crystal 24 and the N poles 22 and 23 are hermetically housed in a tight storage space formed by a plate-shaped body made of a transparent material, such as glass. 'N, a single picture element 25 is constructed in a storage space area located at the intersection of three adjacent poles 22 and 23. A large number of such picture elements 25 are formed within the space between -.

The color member 19 is made of a light-transmitting material such as a synthetic resin, is formed into a thin film shape, and has red, green, and blue regions 26 indicated by reference symbols R, G, and B extending in a straight line. This area 26 is in contact with 1 vinegar and Ci! , fixed. The three famous intersection areas of the electrodes 22 and 23 in the famous picture element 25 individually correspond to each color portion R, G, and H of the area 26.

The light scattering plate 20 is made of frosted glass, for example, and converts the light from the fluorescent tube 21 into uniform light (i eliminates unevenness of light,
It leads to the colored member 19.

By selectively applying pressure to the electrodes 22 and 23 of the large number of picture elements 2°5, the liquid crystal in the storage space in the intersection area of the electrodes 22 and 23 becomes light-shielding, and a residual electric field is generated. There is even a transparent 1 in the part that is not covered. For example, in picture element 25, one of the three south poles 22 is selected.
A voltage is applied to both electrodes 23 and 23. In this way, a color image can be displayed. ' to electrode 22.23
This can be done by applying a voltage to, for example, a microcomputer. ! Iv'l < 1I
The lj image requires an activation time of the liquid crystal that lasts longer than the afterimage opening l/30 seconds of the human eye;
3-way capacitor? May be connected.

As described above, according to the present invention, the structure for light shielding etc. can be miniaturized.
