Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure of a panel of a liquid crystal display device and a method of dividing electrodes.

An object of the present invention is to simplify the structure of a panel by making the counter electrode substrates of a liquid crystal display device that displays characters or pixels have the same pattern, and to make it possible to manufacture a panel at low cost by using a common counter substrate.

Another object of the present invention is not only to simplify the structure of the panel, but also to standardize the switching elements for drive control of the panel.

The present invention is particularly applicable to large panels with bidirectional input terminals such as CPU terminal display devices such as character displays, panel games, and educational equipment panels, as well as small panels for calculators and watches, in which input terminals are bidirectionally separated. For those using the same technology, it is possible to simplify the structure and use common substrates and elements.

FIG. 1a is a front view of a conventional liquid crystal display device, and FIG. 1b is a side view, 1 is a lower transparent substrate (shown in FIG. The substrates face each other, and the lower transparent substrate 1 is treated with transparent electrodes 3-1 and 3-2.

The transparent electrodes 3-1, 3-2 are control terminals in the vertical direction of the panel, and are divided into upper and lower sections.

Reference numeral 4 denotes a transparent electrode on the upper transparent substrate 2, which serves as a horizontal control terminal.

If the panel in this state is a TN type panel, polarizers, filters, reflectors, etc. are added to the top and bottom of the panel.

In the conventional panel of FIG. 1, transparent electrodes 3-1 and 3
-2 terminal, the input order of pixel numbers and characters is that when you look at the panel from the front, the transparent electrode 3-1 turns counterclockwise, and the transparent electrode 3-2 turns clockwise. When electrically mounting a switching element, the order of coupling is reversed.

Also, the size of the substrate is different. The present invention eliminates such drawbacks, and embodiments thereof will be described with reference to FIGS. 2, 3, and 4.

In addition, a shows a front view, and b shows a side view.

In FIG. 2, 5 is an upper substrate, and 6 is a lower substrate, which can be shared by the substrate in FIG. 3.

7 is a polarizing plate or a combination of a polarizing plate and a reflecting plate.

8 is a polarizing plate or a combination of a polarizing plate and a filter.

Reference numeral 9 indicates electrodes on the upper substrate 5 and the lower substrate 6, which are horizontal electrode pattern lines.

(Illustrated in FIG. 3) 10 is also a vertical electrode pattern line.

(Illustrated in Figure 3) 9-1 and 9-2 are horizontal electrode terminals of the electrode pattern line 9, 10-1 and 10-2 are vertical electrode terminals of the electrode pattern 10, and 9-1 and 9-2 are horizontal electrode terminals of the electrode pattern line 9. -1,
Similar to 9-2, they are installed facing each other.

In other words, the control input order of the input terminals is clockwise for both boards.

Therefore, the control element can be shared.

FIG. 4 shows a control element 13 on an upper substrate 11 and a lower substrate 12.
The control elements are a liquid crystal drive drive circuit or a drive circuit, a control circuit, a CPU, etc., and may also be a shift register and a drive circuit.

Further, the elements are composed of low power type elements such as CMOS and SOS.

Furthermore, as explained in the panel description of FIG. 2, the terminal order of the input terminals is the same in the panel shown in FIG.
3 can be shared.

As described above, according to the present invention, all types of liquid crystal panels, such as field effect type, dynamic scattering type, and guest host type, can be manufactured using common electrodes on opposing substrates, and the order of input terminals can also be made the same.

Therefore, the elements attached to the substrate can be shared, making it possible to standardize and simplify device parts, making manufacturing easier, increasing reliability as a liquid crystal display device, and having great industrial value.
