Abstract

The invention provides a driving circuit, a driving method and a display device, and relates to the technical field of display. The driving circuit is used for the display panel. The display panel comprises a plurality of sub-pixels; the driving circuit comprises a GOA driving circuit. The GOA driving circuit comprises a first GOA unit which is configured to output a first scanning signal of the first GOA unit of the current stage according to a first clock signal and a first scanning signal of the first GOA unit of the previous stage; a control module, wherein the output end of the first GOA unit is electrically connected with the same-level control module, and the control module is configured to control the output of the first scanning signal according to the refresh control signal; a second GOA unit of which the input end is electrically connected with the same-level control module, wherein the second GOA unit is configured to output a second scanning signal according to a second clock signal and the output signal of the control module, and the second scanning signal is configured to control the refreshing of the sub-pixels in the same row. According to the driving circuit, partial picture updating in the display device is achieved by refreshing partial pixel voltage, and the driving circuit has low power consumption.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a driving circuit, a driving method, and a display device. Background technique [0002] With the rapid development of display technology, people have higher and higher requirements for the battery life of display products. In some special screens (such as static screens or partially updated screens), most of the pixel voltages in the display screen do not need to be refreshed. However, the current pixel driving technology still needs to refresh all the pixel voltages in one frame when updating the picture content. This repeated refreshing causes waste and increases the power consumption of display products. [0003] At present, there is an urgent need to provide a new driving circuit to solve the above problems. Contents of the invention [0004] Embodiments of the present application provide a driving circuit, a driving method, and a display device. The drivi...
