[0003] However, in the prior art, there is often a parasitic capacitance between the data (data) line and the common electrode. When the voltage of the data line changes, the parasitic capacitance will contact the common electrode Coupling occurs between them, thereby affecting the voltage of the common electrode, causing the display screen on the TFT-LCD to easily appear horizontal crosstalk, thereby reducing the display effect and quality of the display screen, and affecting the display reliability of the display panel

The invention relates to a horizontal crosstalk elimination method, a common electrode voltage adjustment system and a display device. The horizontal crosstalk elimination method comprises the following steps: respectively acquiring a first brightness value, a second brightness value and a flicker value corresponding to a first test pattern, a second test pattern and a third test pattern under different common electrode voltages; calculating a brightness difference value between the corresponding first brightness value and the second brightness value, and obtaining a first difference value common electrode voltage corresponding to the minimum difference value; acquiring a second difference value common electrode voltage corresponding to the minimum flicker value; the average value of the first difference value common electrode voltage and the second difference value common electrode voltage serves as the target common electrode voltage. According to the horizontal crosstalk elimination method, the common electrode voltage is determined according to the two factors of horizontal crosstalk and picture flicker, the phenomenon that when the data line voltage changes, stray capacitance is coupled with the common electrode, the common electrode voltage is affected, and horizontal crosstalk occurs to a display picture is effectively avoided, and the display effect and reliability of the display device are improved.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a horizontal crosstalk elimination method, a common electrode voltage adjustment system and a display device processed by the method. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has many advantages such as thin body, power saving, no radiation, etc., so it is widely used in LCD TV, mobile phone, Personal Digital Assistant (Personal Digital Assistant, Electronic devices such as PDA), digital cameras, computer screens, projectors or notebook computer screens are dominant in the display field. A common electrode and a pixel electrode are usually arranged in a TFT-LCD. By adjusting the electric field change between the common electrode and the pixel electrode, the liquid crystal molecules can be controlled to deflect to different degrees, so that the display panel can display different grayscale images. [0003] However, in the p...
