Grid integrated drive circuit, display panel and display device

Abstract

The invention discloses a grid integrated drive circuit, a display panel and a display device. The grid integrated drive circuit comprises a plurality of shifting register units which are in cascade connection and at least one signal line used for inputting control signals to the grid integrated drive circuit. The signal line is provided with signal output branches with the number being smaller than the number of the shifting register units. At least one signal output branch is connected with control signal input ends corresponding to at least two shifting register units, and thus it can be guaranteed that the obtained signal intensity attenuation phenomenon of at least some shifting register units is retarded. Compared with the mode that all control signals are input from one end of the display panel and sequentially pass through all the shifting register units in the grid integrated drive circuit in the prior art, the grid integrated drive circuit can effectively retard the output intensity attenuation of all the control signals, the output strength uniformity of all the control signals can be effectively improved, and the quality of displayed images and the working performance of the display panel are guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate integrated driving circuit, a display panel and a display device. Background technique [0002] At present, display technology is widely used in the display of TV, mobile phone and public information. Flat-panel displays used for displaying images are being vigorously promoted because of their ultra-thin and energy-saving advantages. Most flat-panel displays require gate integrated drivers. The circuit is used to output gate scanning signals to control the display panel to realize the functions of progressive scanning and frame-by-frame refresh, so that the image data input to the display panel can be refreshed in real time, thereby realizing dynamic display. The gate integrated drive circuit includes multiple cascaded shift register units, and the gate drive function is realized through the shift register unit, which can save the need to make a gate drive chip se...
