Abstract

PURPOSE:To enable the display of the exterior and interior wall surfaces of a building electrically variably in colors and patterns by forming ECDs as tiles of a specified size and individually providing the ECDs with electrodes. CONSTITUTION:A screen 1 formed by a personal computer 1 is sent to the ECD (electrochromic display) tile 3 or ECD films stuck on the wall surface of the building. The individual ECD elements 5 are selectively energized in correspondence to the screen 2 of the personal computer, by which the screen formed of the personal computer is displayed on the ECD tiles 3 or the ECDs. The ECD tiles 3 or the ECDs are slowly uniformly colored over the entire part and the color of the wall surface is inverted if the personal computer is not used. The panels are stuck in the form of the tiles or films to the back surface and large-sized screens of the stage of a theater where the backgrounds are frequently replaced according to scenes. The panels are stuck in the form of the tiles or films are stuck to the walls and large-sized screens of the rear surface of a lobby, etc., of a hotel, etc., where the interiors are preferably changed according to seasons.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique and an apparatus for electrically variably displaying colors and patterns on exterior and interior wall surfaces of a building.

[Prior art]

(1) Various ECD (Electro Chromic Display) devices are known in publications as substances that reversibly develop color when an electric current is applied (for example, “Electrochromic Display” Industrial Book, P
Four). (2) Tungsten oxide (WO3) is used as the ECD element, both sides are made of glass and the inner surface is molded into an encapsulating tile, and the other is a transparent synthetic resin whose inner surface is molded into an ECD enclosing film. Are known. (Ibid., P152, 125). (3) Currently, prototypes of ECD panels are available, but their use is limited to the following. 1) Information display panel (Tokuyama Soda Co., Ltd.'s pamphlet) 2) Leakage detector, ground fault detector (“Electrochromic chip display”)
Industrial books, P153-157) 3) Light control glass, light control glasses (Ibid P161, P168) Reference number = P5083-004

These have the following drawbacks. (1) Since the electrolyte is enclosed and the electrodes are individually attached, the shape of one element cannot be made as small as a dot of a normal liquid crystal.
Therefore, the arrangement density of the elements cannot be increased, and when displaying Chinese characters, it is difficult to eliminate the jaggedness of the shaded portion. (2) Since it uses an electrochemical reaction, it takes time for the color to appear and then disappear. (3) At present, the prototype WO3 is blue on a white background, but the contrast is weak as a display. (4) Since it is a light-receiving type that does not emit light, it is not suitable for displaying advertisements, which requires attention.

The problems described above can be utilized by conversely utilizing the peculiar characteristic of ECD, which has been a drawback of conventional ECD, by selecting the location and time zone in which ECD is used. . (1) ECD is molded as a large tile, and an electrode is provided on each element. (2) Alternatively, the ECD is molded as a large film, and electrodes are provided on each element. (3) Attach the ECD tile or film to the wall as the interior and exterior of the building. (4) Connect the power of the ECD element electrode to the personal computer.

[Action]

(1) Send the screen 2 created by the personal computer 1 to the ECD tile 3 or ECD film 4 attached to the wall surface of the building. (2) Each ECD element 5 is selectively energized according to the screen 2 of the personal computer, and the screen created by the personal computer is E
It is displayed on the CD tile 3 or the ECD 4. (3) When a personal computer is not used, the entire ECD tile 3 or ECD 4 develops color slowly and uniformly, and the color of the wall surface is reversed. Reference number = P5083-004

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. (1) The present invention is applied in the form of a tile or a film on a large wall or wall on the back of a theater stage where the background is frequently changed depending on the scene. (2) The present invention is attached in the form of a tile or a film on a lobby of a hotel or the like whose interior is preferably changed depending on the season, a wall surface on the back of an entrance of an inn or the like, or a large screen. (3) The present invention is applied in the form of a tile or film to a restaurant, a wall surface on the back of a bedroom or the like, or a large screen where it is better to change the atmosphere of the room between the daytime zone and the nighttime zone. (4) When it is desired to make an impression of the entire building, the present invention is applied to the entire outer wall or a characteristic portion in the form of tile or film. (5) In either case, the electrodes of the ECD element are connected to the power source via a personal computer or directly.

The following effects can be obtained by implementing the present invention. (1) Effects in places of use 1) When the present invention is attached to a large wall or wall on the back of a theater stage, the background of the stage can be electrically displayed on a personal computer screen, which is a work that was conventionally replaced as a large tool. It disappears and continuous performances are possible. 2) When the present invention is installed on a large wall or wall on the back of a lobby of a hotel or the entrance of an inn, it is possible to produce a sense of the season by sending a screen in accordance with the season on a personal computer. The number of decoration tools can be reduced. 3) When the present invention is attached to a wall surface on the back of a restaurant, bedroom, etc., or a large screen, the atmosphere of the room can be changed between the daytime zone and the nighttime zone by sending a screen according to the time with a personal computer. 4) When the present invention is attached to the entire outer wall or a characteristic part, the impression of the entire building can be given to the customer by turning on / off the power supply of a personal computer or directly. Reference number = P5083-004

───────────────────── (2) Appropriate effect of ECD element In the above cases, the characteristics of the conventional ECD element, which have been regarded as defects, can be used to the contrary. . 1) If one element shape cannot be made small, it will be one of the expressions by considering it as a tile or mosaic pattern on the wall surface, and the problem will be solved. 2) The cases where it takes time for the color to appear and then to disappear further and the cases where the contrast is weak are the children whose atmosphere changes without being noticed quietly, and are suitable as a building interior that values dignity. 3) The light-receiving type that does not emit light is that conventional indirect lighting can be used as it is, and it is suitable as a building interior that emphasizes the atmosphere. 4) The ECD element has a memory effect, and once it reacts and develops color, it is retained even when the current is cut off, and the ECD element has a power saving effect.
