Problems solved by technology

[0006] Existing gate drive circuits usually include cascaded multi-level gate drive units. The scanning method is that one level of gate drive units scans a row of scan lines. In each frame scan time, all gate drive units need to participate in Scanning, the power consumption of the gate drive circuit in this scanning mode is relatively large, the working time of each level of gate drive unit is long, the loss is large, and it cannot meet the product standards of green energy saving

Abstract

Provided are a display driving circuit and a display device. The display driving circuit comprises a gate driving circuit 1 and a plurality of rows of parallel spaced scanning lines 2 electrically connected to the gate driving circuit 1; the gate driving circuit 1 comprises multiple stages of gate driving units 21, wherein odd-numbered stages of gate driving units 21 are cascaded and even-numbered stages of gate driving units 21 are cascaded; by enabling each stage of GOA unit 21 to correspond to two rows of scanning lines 2, odd-numbered stages of GOA units 21 and even-numbered stages of GOA units 21 are alternately scanned, so that the working time of each stage of GOA unit 21 is halved, thereby reducing product power consumption, prolonging product service life, and improving the energy-saving level of the product.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving circuit and a display device. Background technique [0002] A Liquid Crystal Display (LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc., occupy a dominant position in the field of flat panel display. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter substrate (ColorFilter, CF), and apply a driving voltage on the two substrates to Cont...
