Liquid crystal display panel and adjustment method thereof

Abstract

The embodiment of the invention provides a liquid crystal display panel and an adjustment method of the liquid crystal display panel, and relates to the technical field of display. The changes of the capacitance ratios in pixel units can be monitored in real time, the reference voltage value of a public electrode can be adjusted in real time according to the conditions of environment changes, and therefore the image flicking phenomenon on the liquid crystal display panel can be kept at the lowest degree. The liquid crystal display panel comprises an array substrate, wherein the array substrate comprises a plurality of pixel units which are arranged in a matrix mode, each pixel unit comprises a first transistor, a second transistor, a first data line, a second data line, a first data line connection line, a first gate line, a second gate line, a second gate line connection line and a pixel electrode. The liquid crystal display panel further comprises the public electrode. The liquid crystal display panel which can keep the image flicking display at the lowest degree can be manufactured.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and an adjustment method thereof. Background technique [0002] Currently, if figure 1 As shown, the pixel unit 100 in a Thin Film Transistor-Liquid Crystal Display (TFT-LCD for short) is usually composed of a thin film transistor (TFT), a storage capacitor (Cst), and a device for applying to liquid crystal molecules. voltage constitutes the pixel electrode. [0003] figure 2 It is the signal waveform diagram of the above pixel unit. Among them, when the pixel unit structure of the prior art is used for display, the voltage (Vp) in the voltage node P of the pixel electrode, that is, the voltage related to the storage capacitor on the gate line transitions from a high level voltage to a low level At the moment of the voltage, only ΔVp (jump voltage) drops, that is, the voltage of the pixel electrode fluctuates by ΔV, which leads to the flicker ...

AI Technical Summary

Problems solved by technology

[0011] In the structure of the pixel unit, it is difficult to directly measure the change of the capacitance value of the capacitance Cgs, the capacitance Clc, and the capacitance Cst, that is, the capacitance ratio Cgs / (Cgs+Clc+Cst) in the pixel unit is difficult to determine, so that the TFT-LCD leaves the factory The amount of change of ΔVp set at the time cannot be determined, and it is difficult to adjust the original reference voltage Vcom of the common electrode in real time according to the change of the environmental conditions, so the reference voltage Vcom of the common electrode cannot keep the flickering degree of the TFT-LCD screen at a minimum degree, seriously affecting the viewing effect
