Conventionally, in such a configuration, the size of the display electrode (3) is
250x300μ, the voltage of the signal applied to the train (D) K is 7.5V, the voltage of the signal applied to the gate (G) is 15V, and the number of information signal lines shared by the drain (D) is 2.
When time-division driving is performed with 40 lines and 220 timing signal lines, it is possible to create a display panel that is practical and has no noticeable delay in display response. However, when the display electrode (3) is made larger than the above-mentioned dimensions, the current flowing out from the FF1T source (S) becomes insufficient to drive the large display electrode f31, resulting in poor display response and display contrast. The disadvantage of decline appears. In this case, it may be possible to increase the voltage H- applied to the signal line +61 (71), but with this type of drive circuit that is highly engineered, it is difficult to obtain high voltage. Also, adjusting the voltage is not easy.Also, when increasing the number of display electrodes (3), timing signal lines (6
) The same mJ problem as mentioned above occurs because the opening time when driving a single cylinder is shortened.

In order to expand the display area, the display area is self-sealed! The Omachi FB+ front panel can achieve high response speed and display contrast without increasing the display contrast, which cannot be achieved with the conventional method of increasing the image quality. It is still composed of one pixel or multiple display percentage frames and FETs, so even if the FKT were to become obstructed and become inoperable, the FET would cover it, so the contrast would deteriorate somewhat. Even so, the influence it has on the whole story is careless.
