发明名称 Liquid Crystal Display Device and Liquid Crystal Display Driving Circuit
摘要 A gradation voltage adjustment section for increasing a positive gradation voltage VHX of an X-th gradation and a negative gradation voltage of the X-th gradation so that the increment corresponds to a charge pull-in amount DeltaV is provided in a gradation voltage generation circuit of each source driver. In at least one embodiment, a center value between the positive and negative gradation voltages is adjusted for each driver in accordance with a slant of the charge pull-in amount DeltaV in a direction of a gate signal line, thereby suppressing a flicker without varying a gradation characteristic. Further, a center value between the positive and negative gradation voltages is adjusted for each horizontal line or for every plural lines in a single frame in accordance with a horizontal direction deviation and a vertical direction deviation of the charge pull-in amount DeltaV in a transfer block, thereby suppressing a flicker without varying a gradation characteristic.
