Description

Technical field

The present invention relates to a liquid crystal display device including a plurality of back electrodes and a plurality of surface electrodes arranged in a direction perpendicular to the back electrodes, and performing a display using a combination of the back electrodes and the surface electrodes, and using the same. Liquid crystal chessboard of a liquid crystal display device. current technology

As is known to all, the graphics displayed by a liquid crystal display device are determined by the shape of the electrodes inside them. According to the shape of the electrodes, they can be divided into two types: segment display and matrix display. The internal electrodes of the liquid crystal display device of the matrix display type are vertical strip electrodes. The liquid crystal is placed between the vertical strip electrodes, and is displayed as a combination of the intersections of the strip electrodes, so that arbitrary graphics can be displayed. However, its disadvantage is that, especially when the contours of the displayed graphics are large, a sufficient number of dot matrixes are necessary to clearly display the graphics, and thus cannot meet the requirements of low cost such as a portable liquid crystal display device.

For example, the inventor of the present invention has tried to display a checkerboard pattern such as Go or Backgammon with a matrix display method. The results show that the dot matrix required to display a display unit is at least 7x7, and the dots required to obtain better display quality The number of arrays must be increased, which greatly increases the hardware cost of the LCD checkerboard. The electrodes of a segment display type liquid crystal display device include a back electrode and several segment electrodes. Different figures (such as numbers) are displayed through different combinations of segment electrodes, so the display content is limited. Summary of the Invention

In order to achieve the above first object, the solution of the present invention is: a combination of a plurality of back electrodes and a plurality of surface electrodes whose arrangement direction is perpendicular to the back electrodes is formed by a combination of the back electrodes and the surface electrodes. In a liquid crystal display device performing display, the back electrode and the surface electrode are separated It is divided into at least two sub-electrodes having a given shape to display a plurality of different patterns at the intersections of the electrodes through different combinations of the back sub-electrode and the face sub-electrode.

In order to achieve the above-mentioned second object, the solution of the present invention is: In a liquid crystal chessboard composed of a disk body, a disk surface, and an electronic circuit provided in the disk body, the disk surface is composed of such a liquid crystal display device, and the liquid crystal display device Comprising a plurality of back electrodes and a plurality of surface electrodes arranged in a direction perpendicular to the back electrode, the back electrode and the surface electrode being respectively divided into at least two sub-electrodes having a given shape to pass through the back sub-electrodes and Different combinations of the surface electrodes display various graphics.

According to an aspect of the present invention, the back electrode and the surface electrode are respectively divided into a first sub-electrode and a second sub-electrode each having a given shape.

Thus, according to the present invention, the number of electrode units to be controlled per display unit is only 2

X 2, Obviously, the required hardware cost is greatly reduced compared with the matrix method. Brief description of the drawings
