本发明公开了一种既能够提高画质，又能够减少耗电量的显示装置及其驱动方法。在使用n行点反转驱动来控制显示装置时，以n帧为周期，每帧使副像素的极性模式移位1行。并且，在源极驱动器的输出端的极性进行转换的每n水平扫描期间，使输出端之间短路，进行电荷回收。通过这些方法，能够实现在提高画质的同时，减少耗电量。 If a display is subjected to n line dot inversion drive control, the polarity pattern of sub-pixels is shifted line by line in a cycle of n frames. Furthermore, in every n horizontal scanning periods in which the polarities of output terminals of a source driver are switched, at least two of the output terminals are short-circuited to carry out electrical charge recovery. By using these methods, it is possible to achieve a reduction in power consumption while improving image quality.
