Problems solved by technology

[0009] However, one of the functions of the storage capacitor is to reduce the influence of the leakage current on the voltage of the liquid crystal unit, that is, to assist the liquid crystal unit to store charges. The smaller the capacitance of the storage capacitor is, the lower its ability to assist the liquid crystal unit to store charges
Therefore, by changing the capacitance of the storage capacitor so that each pixel maintains the same V FD , one of its disadvantages is that the smaller the storage capacitor is, the lower its ability to assist the liquid crystal cell to store charge

Abstract

The low-flicker liquid crystal display panel includes several signal lines, several scanning lines and several pixels. Each of the pixels includes one liquid crystal unit with pixel electrode and memory unit and one switching transistor. The switching transistor includes one grid connected electrically to one the scanning lines, one drain and one source. Between the grid and the source, there is one superposed region, and the area of the superposed region increases with the increased distance between the input of the scanning line corresponding the superposed region and the pixel corresponding to the superposed region.

Description

technical field [0001] The present invention relates to a liquid crystal display panel (liquid crystal display, LCD), in particular to a low-flicker liquid crystal display panel. Background technique [0002] Thin film transistor flat panel displays, especially thin film transistor liquid crystal displays (hereinafter referred to as TFT-LCD), mainly use thin film transistors arranged in a matrix to drive liquid crystal pixels with appropriate electronic components to produce rich and bright graphics. Because TFT-LCD has the characteristics of light and thin appearance, low power consumption and no radiation pollution, it is widely used in portable information products such as notebook computers (notebood), personal digital assistants (PDA), and even gradually The trend of CRT monitors replacing traditional desktop computers. [0003] Please refer to figure 1 and figure 2 , figure 1 It is a schematic diagram of a general TFT-LCD, figure 2 Then it is a schematic diagram...
