Abstract

The present invention provides a liquid crystal panel driving circuit, including: an array substrate with m rows*n rows of TFT pixel units distributed, a gate controller, a source controller, and m scanning arrays distributed between the rows and columns of the TFT pixel units line and n data lines; each row of TFT pixel units is connected to a scan line, with three adjacent rows of TFT pixel units as a row cycle, each row cycle includes the first scan line, the second scan line and the third scan line , and are respectively connected to the same gate driver chip pin in the gate controller through the first gate control switch, the second gate control switch and the third gate control switch, and each column of TFT pixel units is connected to a data line to correspond to The adjacent three columns of TFT pixel units are a column period, and each column period includes a first data line, a second data line, and a third data line, and is controlled by the first source control switch, the second source control switch, and the third source respectively. The switch is connected to the same source driver chip pin in the source controller.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a driving circuit of a liquid crystal panel. Background technique [0002] Liquid crystal display is a flat and ultra-thin display device, which is composed of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays have low power consumption, high image quality, small size, and light weight, so they are favored by everyone and become the mainstream of displays. With the increasing demand of users for large-screen TVs and high display quality, LCD TVs are being developed towards large sizes and ultra-high resolutions. The resolution is expanded from Full HD (Full HD) 1920×1080 to 4K×2K, and even 8K×4K ultra-high resolution. The improvement of image display quality is increasingly challenging panel power consumption and production costs. How to reduce panel power consumption and produ...
