Abstract

The invention provides a display drive circuit and a display device. The display drive circuit comprises a plurality of driving groups. Each driving group is electrically connected with all scanning lines of the display device; wherein the scanning lines are electrically connected with a display unit of the display device, each driving group controls the display function of the display device through the scanning lines, each driving group is electrically connected with a trigger signal line, and the trigger signal lines control the multiple driving groups to alternately drive the display device to display; the display device comprises the display drive circuit. The multiple driving sets are arranged to work alternately, so that the working time of the single driving set is shortened, the working stability of the driving sets is maintained, and the failure risk is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display driving circuit and a display device. Background technique [0002] With the development of flat panel display technology, high resolution, high contrast, high refresh rate, narrow frame, and thinning have become the development trend of flat panel display. GOA (Gate Driver on Array, array substrate row drive) technology is to use the array substrate manufacturing process in the existing display to manufacture the gate row scanning drive signal circuit on the array substrate to realize the drive method of progressive scanning of the gate. It is beneficial to realize narrow bezel or even bezel-less design of the display device, so it is favored. [0003] The GOA circuit contains multiple driving thin film transistors and switching thin film transistors. These thin film transistors will experience unstable performance under long-term working conditions, which ...
