液晶显示装置及其驱动方法
Abstract:
在进行中止驱动的液晶显示装置中既抑制功耗的增大又有效地抑制闪烁的发生。在从上次的刷新帧到产生规定次数的中止帧为止图像变化判别部(11)检测到图像变化的情况下，反转驱动控制部(13)将检测到图像变化的帧的下一帧定为以列反转驱动为反转驱动方式的刷新帧。在从上次的刷新帧到产生规定次数的中止帧为止图像变化判别部(11)未检测到图像变化的情况下，反转驱动控制部(13)将最后的中止帧的下一帧定为以点反转驱动为反转驱动方式的刷新帧。
Abstract(English):

When an image change determination portion (11) detects an image change in a period from the previous refresh frame until generation of a predetermined number of times of pause frames, a reversal driving control portion (13) sets the next frame after a frame where an image change has been detected to a refresh frame where a reversal driving technique is a column-reversal driving. When the image change determination portion (11) does not detect an image change in the period from the previous refresh frame until generation of the predetermined number of times of pause frames, the reversal driving control portion (13) sets the next frame after the final pause frame to a refresh frame where a reversal driving technique is a dot-reversal driving.
