Embodiment Construction

[0015] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0016] see figure 1 , this picture is commonly used in display screen performance testing. In the case of normal display, it includes 127 gray parts on the periphery and 255 white parts in the middle. For Demux (de-interleaved) LCD, due to the manufacturing process of Demux TFT, the opening current of Demux TFT will be different, which will cause some abnormal phenomena in the display of Demux LCD. In the case of abnormal display, we call it horizontal crosstalk.

[0017] figure 2 In the shown embodiment, the NMOS type TFT source / drain judgment is introduced. The current flows from high voltage to low voltage. The carriers of NMOS are electrons, and the electron flow is opposite to the current direction. Simply put, the end with h...

Abstract

A pixel driving method comprises the following steps: detecting a data signal change condition of a panel Data line, and when the data signal is detected to be changed, if the data signal is changed from a low absolute value signal to a high absolute value signal, improving the voltage value of a high absolute value gray-scale signal of a negative sub-pixel; and if the data signal is changed fromthe high absolute value signal to the low absolute value signal, reducing the voltage value of a low absolute value gray-scale signal of the negative sub-pixel. Different from the prior art, the Dataline is a data signal line, according to the technical scheme, by adjusting the gamma values of the RGB sub-pixels, the coupling phenomenon of positive and negative Data to the VCOM is improved, the horizontal crosstalk phenomenon is improved, and the display effect of a Demux liquid crystal display screen is better.

Description

technical field [0001] The present invention relates to the field of pixel driving, in particular to a design of a pixel driving method. Background technique [0002] For the Demux LCD, due to the manufacturing process of the Demux TFT, the opening current of the Demux TFT will be different, and the existing LCD will cause some abnormal phenomena in the display of the Demux LCD. Here put as figure 1 The abnormal display shown is a phenomenon called horizontal crosstalk. Contents of the invention [0003] Therefore, it is necessary to provide a new pixel driving method to achieve the technical effect of solving the horizontal crosstalk problem. [0004] In order to achieve the above object, the inventor provides a pixel driving method, including the following steps, detecting the change of the data signal of the Data line of the panel, and when the change of the data signal is detected, the data signal is changed from a low absolute value signal to a high absolute value s...
