Problems solved by technology

In the existing liquid crystal display, the Vcom value input by the IC is always constant, but during use, the temperature of the liquid crystal display changes, and the flicker value of the liquid crystal display also changes all the time. Therefore, the Vcom value input by the IC The flicker value cannot be adjusted effectively all the time, resulting in poor display quality of the LCD

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a driving circuit and a driving method thereof. Background technique [0002] Liquid crystal displays have different flicker (flicker) values ​​at different temperatures, and the flicker value is determined by the characteristics of the liquid crystal material itself and TFT (thin film transistor). At different temperatures, the dielectric constant of the liquid crystal material is different, which leads to different CLC (capacity) of the liquid crystal material at different temperatures, and the leakage current of the TFT at different temperatures is also different. The flicker value of the liquid crystal display is different at different temperatures. [0003] Adjusting the Vcom (common voltage) value of the liquid crystal display can reduce the flicker value of the liquid crystal display to a certain extent, but for different flicker values, the adj...
