Example Embodiment

[0018] Please refer to FIG. 1, which is a schematic diagram of a liquid crystal display panel of the present invention. The liquid crystal display panel 100 includes a plurality of scan lines 1, a plurality of data lines 2, a scan driver 3, a data driver 4, and a controller 6 connected to the scan driver 3 and the data driver 4. The scan lines 1 and the data lines 2 are arranged in rows and columns. The matrix arrangement forms a plurality of pixels 5. The scan driver 3 and the data driver 4 are respectively connected to the scan line 1 and the data line 2 for driving the pixels 5 to display images. Each pixel 5 includes a light sensing element (not shown), the light sensing element is embedded in the pixel 5 using a semiconductor process, and the light sensing element can be a photodiode (Photonic Diode) or a phototransistor ( Photonic Transistor). The liquid crystal display panel 100 is divided into five detection areas, the central area is the first detection area E, and four d...

Abstract

A liquid crystal display face plate consists of multiple scan line, multiple data line, scan actuator, data actuator and controller, setting scan lines and data lines to be line-column arrangement to form multiple pixel, connecting two said actuators separately to said scan line and data line for driving pixel to display image, dividing said face plate to be five detection regions for regulating voltage of common electrode at different time and fixing voltage of common electrode at the same time according to detection result of these five detection regions.

Description

【Technical Field】 [0001] The present invention relates to a liquid crystal display panel and a voltage adjustment method thereof, in particular to a liquid crystal display panel and a voltage adjustment method thereof that can reduce the degree of flicker. 【Background technique】 [0002] At present, it is generally believed that the cathode ray tube display has a flicker problem, while the liquid crystal display (LCD) does not have the flicker problem. In fact, both cathode ray tube displays and liquid crystal displays have certain flicker. Therefore, we must use different correction methods to reduce the degree of flicker. [0003] Give an example of the cause of flickering on the LCD. It is assumed that the factory voltage of the common electrode Vcom of the liquid crystal display is 5.5V, and the amplitude of the video signal is between 0V and 10V, so the segment voltage is between -5.5V and 4.5V. During the dot inversion process of a liquid crystal display, if the voltage of ...
