Abstract

PURPOSE:To freely display a picture and a pattern on window glass by constituting a transmissive type liquid crystal display device which can displays an image with one or plural windows and providing a computer which controls the image. CONSTITUTION:One or plural transmissive type liquid crystal display devices 61-63 are used instead of the glass of a window, and frame memories 51-56 for storing images to be displayed by the display devices 61-63 and the computer 1 which generates images to be displayed or reads the images out of a memory device 2 and sets them in the frame memories 61-63 are provided. The computer 1 segments parts corresponding to the display ranges of the liquid crystal display devices 61-63 to which image information is to be sent from the images which are generated or read out and then sends them to the frame memories 51-56, and this operation is repeated in order. Consequently, the picture or image can be displayed on the window freely.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to electronic stained glass that can freely display pictures on window glass used in homes and the like.

[Conventional technology]

Conventionally, as described in Japanese Utility Model Application Publication No. 61-171029, a liquid crystal layer was provided between two glass plates in household window glass, so that it was possible to change the area to which voltage was applied. Transparent electrodes were provided on two pieces of glass, and the amount of light transmitted could be controlled by adjusting the area of the electrodes to which voltage was applied. Furthermore, as described in Japanese Utility Model Application Publication No. 60-6092, a device has been devised in which a liquid crystal layer is provided on the window glass of an automobile in the same manner as in the conventional example, and the device is used as a blind device. In this example, it is not considered that the area of the electrode to which voltage is applied is variable.

[Problem to be solved by the invention]

Although the above-mentioned conventional technology takes into account the control of the amount of light blocked by the window glass, it does not take into account the pictorial use of drawing pictures and patterns on the window glass to change the atmosphere in the room. An object of the present invention is to freely draw pictures and patterns on window glass.

[Means to solve the problem]

In order to achieve the above object, a window is constructed of one or more transmission type liquid crystal display devices capable of displaying an image, and one or two sets of transmissive liquid crystal display devices capable of displaying an image are arranged to record an image on each liquid crystal display device.
A set of frame memories, a display driver that drives the liquid crystal display device from the image information from this frame memory, creates an image or takes it out from the storage device, cuts out an image in the range of each liquid crystal display device, and sequentially stores it in the corresponding frame memory. This is achieved by providing a computer that manages images to be transmitted.

[Effect]

The computer cuts out a portion corresponding to the display range of the liquid crystal display device to which the image information is to be transmitted from an image generated from geometric information, an image captured by a scanner, or an image from an optical disk, etc., and transmits it to the corresponding frame memory. do. By sequentially repeating this operation, the image will be drawn on the entire window. In this case, since the image corresponding to the part of the crosspiece between the liquid crystal display device and the adjacent liquid crystal display device is removed and displayed, the part of the crosspiece is not displayed, but the displayed image does not become discontinuous between the liquid crystal display devices. .

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 shows the overall hardware configuration of the present invention. 1 is a computer, and 2 is an optical disk device that stores images to be displayed. 3 is an image bus 51 to 56 that sends image information and control information from the computer to control circuits 41 to 43;
is a frame memory that stores images. Two frame memories are provided on each side, and by writing to the frame memory that is being displayed and the frame memory on another side, it is possible to prevent the image from being distorted when updating one image. Generally, a method called a double buffer method is adopted.

Reference numerals 61 to 63 are transmissive liquid crystal display devices, which include a display device main body and a driving device. The liquid crystal display devices 61 to 63 are
It is placed in the window 7 as shown in the figure.

The image will be displayed on window 7. Here, regarding the liquid crystal display device 61, image information in the range handled by the liquid crystal display device 61 is stored in the frame memory 51 or the frame memory 52 and displayed. The control circuits 41 to 43 receive and store image information in the 5 frame memories 51 to 56, control the planes of the frame memories 51 to 56 for displaying one image, and the plane of the frame memory to write image information, according to instructions from a computer.

The operation of the present invention will be explained with reference to a flowchart 8 of the processing performed by the computer 1 shown in FIG. In block 81, the computer 1 writes the frame memories 51 to 56 into which images are to be written.
via the image bus.

Instructs each control circuit. In block 82, one of the liquid crystal display devices w61 to w64 to which the image is to be sent is selected.

The selection method is performed in the order in which the liquid crystal display devices 61 to 64 are lined up, but any order may be used. In block 6 83, which connects the selected liquid crystal display device, for example 61, to the control circuit 41 through the image bus 3, the image shared by one selected liquid crystal display device is generated from graphic information or taken in from the optical disk 2. When the size and position of one selected liquid crystal display device are cut out from the entire image and this information is placed on the image bus 3, the selected control circuit, currently the control circuit 41, takes in the information and stores it in the frame memory 51.
Alternatively, it is written to the frame memory 52.

In block 84, it is determined whether the image information has been sent to all liquid crystal display devices, and if the image information remains, the process returns to block 82 and repeats the process. At block 85.

The image sent through the above processing is displayed.

According to this embodiment, since the computer 1 and the liquid crystal display devices 61 to 63 are connected using the image bus, the computer 1
Compared to the case where the liquid crystal display devices 61 to 63 are individually connected to each other, fewer cables are required for connection.

On the other hand, the computer 1 and the liquid crystal display devices 61 to 63 may be connected in a similar manner.

〔Effect of the invention〕

According to the present invention, pictures and images can be freely displayed on the window. Furthermore, since the images in the gaps created when the liquid crystal display devices are combined are removed and displayed, the quality of pictures and images on the entire screen does not deteriorate.
