Abstract

PURPOSE:To easily make a liquid crystal display screen large in size without impairing the portability of the device by consecutively connecting plural liquid crystal display panels in a plane thereby forming one display plane as a whole direction, and connecting between the adjacent liquid crystal display panels by flexible cables, thereby making it foldable. CONSTITUTION:The display screen whose area is four times as large as each liquid crystal panel as a whole is provided by allowing four sheets of liquid crystal display panels 11-14 to respectively share one display screen 1/4 by 1/4 when it is used under a state that it is unfolded. When it is not used, it can be folded and housed by bending the flat flexible cables 21-23 which connect the respective panels 11-14. In such a way, the display screen of the large area is obtained with the panels 11-14 of the small area which can be comparatively easily obtained. Simultaneously, the display screen can be housed by being folded a small.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique effective when applied to a liquid crystal display device, and further to an image display device, for example, to a technique effective when applied to a large-screen color liquid crystal television. is there.

[0002]

2. Description of the Related Art Recently, liquid crystal display panels have come to be widely used as display devices for miniaturized television receivers and video reproducing devices (for example, Nikkei BP, "Nikkei Electronics, May 29, 1989"). No. 474 "
151-156).

[0003]

However, the present inventors have clarified that the above-mentioned technique has the following problems. That is, in the liquid crystal display device, especially in the color liquid crystal display device, it is very difficult to increase the area of the liquid crystal display panel, so that only a small screen can be obtained. Further, even if a liquid crystal display device using a large-sized liquid crystal display panel is provided, another problem arises in that the device becomes large and portability is impaired. An object of the present invention is to provide a technique for easily increasing the size of a liquid crystal display screen without impairing the portability of the device. The above and other objects and features of the present invention will be apparent from the description of the present specification and the accompanying drawings.

[0004]

Among the inventions disclosed in the present application, a brief description will be given to the outline of typical ones.
It is as follows. That is, a plurality of liquid crystal display panels are connected in a plane direction to form one display surface as a whole, and adjacent liquid crystal display panels are connected by a flexible cable to be foldable. .

[0005]

According to the above-mentioned means, it is possible to obtain a large-area display screen with a small-area liquid crystal display panel that is relatively easy to obtain, and to fold and store the display screen in a small size. This achieves the purpose of easily increasing the size of the liquid crystal display screen without impairing the portability of the device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding parts. 1 to 4 show an embodiment of a liquid crystal display device to which the technique of the present invention is applied, in which 11, 12, 13, and 14 are liquid crystal display panels, and 21, 22, and 23 are liquid crystal displays. A flat flexible cable 3 for connecting the panels is a display driving unit. The four liquid crystal display panels 11, 12, 13, 14 are
As shown in FIG. 1, one display surface is formed as a whole by connecting in the surface direction. Along with this, as shown in FIGS. 2 to 4 showing the cross-sectional state of each part (AA, BB, CC), adjacent liquid crystal display panels (11-12, 12-
13, 13-14) are connected to each other by flexible cables 21, 22, and 23 so that they can be bent 90 degrees in the direction of the arrow.

The above-described liquid crystal display device is used in the developed state shown in FIG. In this usage state, each of the four liquid crystal display panels 11, 12, 13, and 14 shares one display screen with a quarter, thereby providing a display screen having an area four times as large as that of each liquid crystal display panel as a whole. provide. When not in use, each liquid crystal display panel 11, 12, 13, 14
By bending the flexible cables 21, 22, and 2 connecting to each other, as shown in FIG. 5, they can be folded and stored.

As described above, it is possible to obtain a large-area display screen with the small-area liquid crystal display panels 11 to 14 which are relatively easy to obtain, and to fold and store the large-area display screen. As a result, it is possible to easily increase the size of the liquid crystal display screen without impairing the portability of the device.

Although the invention made by the present inventor has been specifically described based on the embodiments, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say. For example, the liquid crystal display panel may be connected as shown in FIG. In the above description, the case where the invention made by the present inventor is mainly applied to the display device of the television receiver or the video reproducing device, which is the field of application which is the background of the invention, is not limited thereto. For example, it can be applied to a display device of a personal computer.

[0010]

The outline of the typical inventions among the inventions disclosed in the present application will be briefly described as follows. That is, the effect that the liquid crystal display screen can be easily enlarged without impairing the portability of the device is obtained.
