摘要:
A DSD display driving method and driving device thereof are provided. Each of the pixels of the display is selectively driven by a pair of select lines, and the polarities of the select signals can be alternately changed in accordance with different frame times. The driving method and the driving device thereof is adapted for balancing the asymmetric positive and negative polarities of conventional pixel voltages and efficiently preventing the flicker phenomenon in a conventional driving method.

A liquid crystal display (LCD) panel and driving circuit having a high response speed is provided. The LC panel at least includes a first group of gate lines, a second group of gate lines, and a first group of source lines, in which gate pulse signals can be fed to the LCD panel through the two groups of gate lines. Preferably, the LC panel further includes a second group of source lines, in which one of the two groups of source lines can be fed with the image data, and the other one is fed with a black image data. Accordingly, the LCD panel can only use the twisted nematic LC or the vertical alignment LC (VA-LC), without need of optically compensated birefringent LC (OCB-LC). Thus, the problems of a fast response speed LC panel using an OCB-LC can be avoided.

A reference voltage selection device suitable for a display device comprising a digital to analog converter is provided. The digital to analog converter may include a plurality of input terminals and may be adopted for providing a displaying voltage to the display device. The selection device may include a reference voltage selector for receiving a plurality of basic reference voltages, wherein the reference voltage selector is suitable for selecting a relationship between the basic reference voltages and the input terminals to reduce an error between the displaying voltage and a predetermined standard voltage.
