Abstract

The invention discloses a liquid crystal display device, which charges a pixel through a high voltage in advance before writing each data signal for displaying an image in the pixel, namely, performs overdrive before writing the data signal for displaying the image in the pixel. The invention further discloses a signal drive method of the liquid crystal display device. Compared with the prior art, the invention has the advantages that firstly, a frame buffer is unnecessarily used so that the cost is saved; secondly, the overdrive is carried out without a complex timing function; and thirdly, if the method is used with the traditional method for comparing pre-signals and post-signals by searching a table, an incorrect torsion angle resulted from liquid crystals subjected to the instantaneous drive can be greatly avoided in the event of performing the overdrive.

Description

【Technical field】 [0001] The present invention relates to a display device, in particular to a liquid crystal display device; [0002] The invention also relates to a driving method, in particular to a driving method of a liquid crystal display device. 【Background technique】 [0003] Overdriving (Over Driving) technology is a technology used to improve the display effect of a liquid crystal display panel. The traditional overdrive technology generally compares the front and back image signals with a look-up table to find a predefined inter-difference voltage value to improve the response speed. This method requires the use of a frame buffer (Frame Buffer) to store the previous image, and then compares it with the previous image. For comparison with the current image, the above-mentioned pre-defined interpolation voltage value also needs to be stored in the memory, and also requires the cooperation of a timing control register (Time Control Register, TCON). [0004] The gen...
