Liquid crystal display device and its driving method

Abstract

The present invention relates to one kind of LCD device and its driving method. A polar distribution controlling signal generating unit is used to generate polar distribution controlling signal output to the polar distribution data driver, and one aperiodic polar array is output to the display panel according to the polar distribution control signal to make pixel unit polarity in the panel in aperiodic distribution. Inside several frames, one half of the frames are complementary with the other half of the frame, that is to say, the polarity of all the pixel units in one half of the frames is opposite to that of all the pixel units in the other half of the frames.

Description

technical field [0001] The present invention relates to a flat display, in particular to a liquid crystal display device and a driving method thereof, which can be applied to a source driver integrated circuit (Source IC) or timing controller of a low temperature polysilicon (LTPS) thin film transistor liquid crystal display, and a thin film In the source drive integrated circuit or timing controller of transistor liquid crystal display and other drive circuits. Background technique [0002] With the development of the optoelectronic industry, flat panel displays have successfully replaced cathode ray tube (CRT) screens. The current flat panel display can be completed by a variety of different technologies, such as: liquid crystal display (LCD), thin film transistor liquid crystal display (TFT-LCD), or organic electroluminescence display (OLED), wherein, liquid crystal display and thin film transistor liquid crystal display The bias voltage is mainly used to control the ali...

Problems solved by technology

Since this approach is based on the picture blocks 110, 120, 130, 140, when the vertical (Column) signal of the display panel 100 is driven by time division multiplexing, if a certain picture (Pattern) makes a certain picture in the display panel 100 If the sum of effective voltages for driving liquid crystals of one polarity is much greater than that of the other polarity, crosstalk (Crosstalk) effect is prone to occur, that is, the image in a certain area of ​​the display panel 100 affects the brightness of adjacent areas, resulting in poor image quality.

[0004] figure 2 It shows the practice of arranging the polarity of the panel 200 in the vertical direction (Data Line direction) to change irregularly, and the polarities of two adjacent picture blocks are opposite, because the horizontal direction (Row Line direction) is positive and negative Neighboring arrangement, so when the panel 200 longitudinal signal is time-division multiplexing drive, a specific picture will also appear. sound effect, making the image quality deteriorate
