The application relates to a display panel driving method, a display driving circuit and a display panel. The shown method includes when it is detected that the display panel has completed the current display, respectively writing reset voltages to the respective reset lines corresponding to the scan driving circuit in the driving circuit, so as to reset the source of the driving TFT in the driving circuit; the reset voltage As the distance between the reset line and the corresponding scanning drive circuit increases, it decreases accordingly. By writing corresponding reset voltages to the reset lines from near to far away from the scan drive circuit, and the reset voltage increases with the distance The large and corresponding reduction has changed the way of inputting the same reset voltage for the entire driving circuit in the traditional technology, and realized that due to the increase in the distance between the reset line and the scanning driving circuit, the reset voltage for writing is reduced, so that the driving The source voltages of the driving TFTs at different positions on the circuit are consistent, thereby improving the display uniformity of the panel.
Description
technical field [0001] The present application relates to the technical field of panel display driving, in particular to a display panel driving method, a display driving circuit and a display panel. Background technique [0002] With the development of display technology, the application of display panels is becoming more and more extensive. During the display process of the display panel, data (Data) and reset voltage (V pre ), in order to ensure the display uniformity of the display panel, the gate voltage (V g ) must reach more than 96% of the data voltage setting value, however, in the display process of the display panel, the source voltage (V s ) control is usually neglected, but due to the source voltage (V s ) are susceptible to factors such as feedthrough formed when the gate is turned off, resulting in source voltages at different locations on the display panel (V s ) will produce a large difference, which will seriously affect the voltage between the gate and ...
