LCD faceplate of active matrix, and driving method

Abstract

The invention discloses an active matrix LCD panel and the driving method thereof. And the LCD panel comprises plural rows of scanning lines, plural columns of data lines, plural liquid crystal pixels at the intersects of the scanning and data lines, plural scanning signal chips, plural data signal chips, and plural black inserting signal chips, where the scanning signal chips continuously generate plural scanning signal groups within a frame period, including a data display-scan signal and a black insert-scan signal and in turn provide them for the scanning lines, the data signal chips provide data signals for the data lines to make the pixels display image data, as the scanning signal chips provide the data display-scan signal for the scanning lines, and the black inserting signal chips provide a black inserting signal for the data lines to make pixels display black states, as the scanning signal chips provide the insert-scan signal for the scanning lines.

Description

【Technical field】 [0001] The invention relates to a matrix liquid crystal display panel and a driving method thereof, in particular to an active matrix liquid crystal display panel capable of displaying images without smear and a driving method thereof. 【Background technique】 [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal display panels are widely used in modern information equipment such as televisions, notebooks, computers, mobile phones, and personal digital assistants. At present, the application of liquid crystal display panels in the TV market is becoming more and more important, but liquid crystal itself is a viscous substance, so its response speed cannot compete with CRT. [0003] Please refer to figure 1 , is an active matrix liquid crystal display panel in the prior art. The active matrix liquid crystal display panel 100 includes multiple rows of scan lines 13 that are parallel to each other, multiple columns of d...

AI Technical Summary

Problems solved by technology

[0006] Due to the liquid crystal's viscous effect, the twisting speed of the liquid crystal is relatively slow. Taking a frame time of 16.7ms as an example, the liquid crystal molecules of the pixel cannot immediately reach the required grayscale brightness within a frame time under the drive of the data signal voltage. In addition, The image display of the previous frame will remain in human vision, causing the image display of the previous frame to affect the image display of the next frame. Therefore, the liquid crystal display panel of the prior art has a smear phenomenon when displaying a dynamic image.
