Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] A method for driving and controlling pixels of a liquid crystal panel. In the method, the time required for switching one frame of a liquid crystal panel picture is a charging cycle, and at least one charging cycle includes a high-voltage charging stage and a voltage correction stage. The voltage amplitude in the high-voltage charging stage is greater than the preset voltage amplitude, so that the liquid crystal pixels can quickly accumulate electricity in a relatively short period of time. The voltage in the voltage correction stage is equal to the preset voltage, so that the voltage is accurately positioned at the preset voltage value.

[0032] Different from the prior art, the present invention divides a charging cycle into a high-voltage charging stage and a voltage correction stage. Since the preset voltage is amplified, the volta...

Abstract

The invention discloses a drive control method of liquid crystal display panel pixels and a liquid crystal display panel. In the drive control method, the demanded time of switching one liquid crystal display panel picture is a charging period, wherein at least one charging period includes a high-voltage charging stage and a voltage correcting stage; the voltage amplitude of the high-voltage charging stage is more than a preset voltage amplitude so that liquid crystal pixels can quickly accumulate electric quantities in a shorter time; the voltage value of the voltage correcting stage is equal to a preset voltage value so that the voltage can be precisely defined in the preset voltage value. According to the drive control method, the liquid crystal pixels can reach the preset voltage value in the short time, and the display quality of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for driving and controlling pixels of a liquid crystal panel and a liquid crystal display panel. Background technique [0002] With the development of liquid crystal displays (LCDs), people have higher and higher requirements for the definition of LCDs, higher resolution requirements for displays with the same size, and larger requirements for panel sizes. [0003] The structure of the existing liquid crystal display panel generally includes: an array substrate and a color filter substrate placed opposite to each other; wherein, the array substrate includes a group of data lines extending along the first direction and a group of gate lines extending along the second direction A plurality of pixel units are defined and distributed in an array, each pixel unit includes a TFT (Thin Film Transistor, thin film field effect transistor, TFT for short), and the color filter sub...
