Crosstalk control method for a liquid crystal display device

Abstract

The invention discloses a crosstalk control method of liquid crystal display equipment. The crosstalk control method comprises the following steps: firstly, calculating so as to obtain a polarity sum of light-proof sub-pixels, checking a list to obtain polarity and a corresponding pixel reference voltage deviation value, so as to obtain a first adjustment value of a reference voltage; meanwhile, when the deviation value is detected, transmitting a control signal to a feedback adjustment unit so as to obtain a second adjustment value of the reference voltage, and performing weighting summation on the two adjustment values, thereby achieving dynamic compensation of the reference voltage. As the reference voltage of the pixel is dynamically adjusted in a mode of adjustment value weighting summation, display crosstalk of the liquid crystal display equipment can be effectively reduced, and display stability of the liquid crystal display equipment can be ensured.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, in particular to a method for controlling crosstalk of liquid crystal display equipment. Background technique [0002] In recent years, liquid crystal display devices have been widely used in many fields, and continue to show a rapid growth trend. At present, liquid crystal display devices are developing in the direction of large size, high resolution, wide viewing angle, and high aperture ratio. Generally, a liquid crystal display device is mainly composed of two glass substrates and an anisotropic liquid crystal layer located between the two glass substrates. The liquid crystal display panel is mainly that the data signal of the pixel is added to the pixel electrode under the control of the gate drive signal to the switch unit, and the reference voltage signal is added to the reference electrode, so as to realize the progressive scanning and display of the image signal on the liquid cryst...

Problems solved by technology

[0003] Liquid crystal display devices usually have such a problem: the gate and drain of each switching element of the switching unit in the liquid crystal display are coupled with the reference voltage and the data signal of the pixel due to the existence of parasitic capacitance, so that the reference voltage is different from the expected The standard value is inconsistent, that is, the actual reference voltage will be higher or lower than the expected standard value

Therefore, when the difference between the pixel voltage signal and the reference voltage is large, it will cause crosstalk in the process of displaying the image on the LCD screen.
