Method for driving LCD faceplate in active matrix

Abstract

The invention discloses an active matrix liquid crystal display (LCD) panel driving method, and the LCD panel comprises a backlight module, plural pixels and plural pixel electrodes, and the method comprises the steps of: firstly dividing each frame period into display period and black insertion period; generating a grey scale voltage which makes the integration of light transmission quantity of a pixel in the display period correspond to image data; successively, supplying the grey scale voltage to the pixel electrodes in the display period; and finally supplying a reset voltage to the pixel electrodes to make the pixels return to a specific initial black state in the black insertion period and simultaneously switching off the backlight module to eliminate the brightness integration produced by response delay of the pixels in the black insertion period. The invention can effectively improve dynamic display effect of a LCD panel.

Description

【Technical field】 [0001] The invention relates to a driving method of a matrix liquid crystal display panel, in particular to a driving method of an active matrix liquid crystal display panel capable of displaying images clearly. 【Background technique】 [0002] Liquid crystal display panels have the advantages of lightness, thinness, and low power consumption, and are widely used in modern information equipment such as televisions, notebooks, computers, mobile phones, and personal digital assistants. At present, the application of liquid crystal display panels in the TV market is becoming more and more important. However, liquid crystal itself is a viscous substance, so its response speed cannot compete with cathode ray tube displays. In the active matrix liquid crystal display panel, taking the display with a frequency of 60 Hz as an example, except for the on and off time of the switch component, the response time required for the liquid crystal panel to switch between gra...

Problems solved by technology

As the number of gray scales increases, the data in the lookup table determined by the gray scale voltages of the two frames before and after increases in series. For example, when the number of gray scales is 8 bits, the capacity of the lookup table needs to be 8×8=64 bits, that is, more The number of gray levels requires a large lookup table capacity, and increasing the capacity of the lookup table will increase the cost. Although it can also be used with a smaller lookup table and some hardware calculations to approach the real lookup table, the effect is not ideal.
