Abstract

The present application is applicable to the field of display technology, and provides a control circuit of a display panel and a display device. The control circuit of the display panel in the embodiment of the present application is used to receive the first clock signal, the first level signal and the second level signal, and according to the first level signal and the second level signal, control the The first clock signal is phase-shifted to obtain the second clock signal and output to the gate drive circuit to realize the phase shift of the clock signal to reduce the load of a single clock signal, and can reduce the number of clock generators in the display panel and reduce the display Panel production costs.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a control circuit of a display panel and a display device. Background technique [0002] With the rapid development of display technology, display panels are widely used in various fields such as entertainment, education, and security. GDL (Gate Driver Less, Array Substrate Row Drive) technology means that the gate driver IC (Gate driver IC) is directly fabricated on the array (Array) substrate, and the gate is scanned row by row by outputting row drive signals. The GDL technology can simplify the manufacturing process of the display panel, save the chip bonding process in the direction of the horizontal scanning line, and reduce the production cost. At the same time, it can improve the integration of the display panel and make the display panel lighter and thinner. [0003] Display panels using GDL technology need to use multiple clock signals to control ...
