Abstract

The present invention provides a liquid crystal display panel, which includes data lines, scan lines and pixel units, wherein the liquid crystal display panel also includes a data drive chip, a scanning drive chipset and a comparison unit, wherein the comparison unit is respectively connected to two scan drive chips, It is used for performing signal compensation on the scan signal output by another scan drive chip according to the scan signal output by one scan drive chip, so that the difference between the scan signals output by the two scan drive chips is smaller than a set value. The present invention also provides a liquid crystal display device. The liquid crystal display panel and the liquid crystal display device of the present invention set a comparison unit so that the output pulses of scanning signals of different driving chips have smaller differences, thereby improving the display effect of the liquid crystal display device.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] As a high-quality flat-panel display device, a liquid crystal display device has the advantages of small size, low power consumption, high resolution, high color saturation, and fast image refresh rate. The liquid crystal display panel generally uses an external driver chip to charge the pixel capacitance in the liquid crystal display panel in a progressive scanning manner. [0003] Usually, the plug-in driver chip has two packaging methods: COF (Chip On Film, chip set on a film) and COG (chipon glass, chip set on a glass plate). As a result, the scanning signal output pulses of different driving chips will be different; thus, the pixel switching capabilities of different pixels will be different, resulting in the display defect of the corresponding liquid crystal display devic...
