Display device for displaying an image if a positive voltage or a negative pole voltage is applied as an image voltage to a pixel electrode

摘要

In a display device of the present invention, a positive pole voltage and a negative pole voltage at which flicker is less likely to occur are calculated in advance. In memory tables, as voltages to be applied to liquid crystal, data of the positive pole voltage is stored, and, instead of the negative pole voltage, a correction value that allows for calculating the negative pole voltage when used in combination with the positive pole voltage is stored. In this way, it is possible to make appearance of the flicker less likely. In addition, it is possible to reduce memory size (specifically, by (A-B)x2⁷ bits) and thereby reduce packaging area and attain lower cost.
