Title:
METHOD FOR DRIVING DISPLAY PANEL, DRIVING CIRCUIT, AND DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2020012934
Kind Code:
A
Abstract:
To provide a method for driving a display panel, a driving circuit, and a display device which can reduce generation of a flicker.SOLUTION: The method for driving a display panel according to an embodiment of the present disclosure includes a writing step of performing a correction operation of making the voltage between the gate and the source of a driving transistor closer to the threshold voltage of the driving transistor in each pixel of the display panel and then applying a voltage pulse to the gate of a second transistor more than one time, thereby writing a signal voltage corresponding to a picture signal to the gate of a first transistor. When two of the voltage pulses applied in the writing step are noted, the crest value of the first voltage pulse applied in the first stage is higher than the crest value of the second voltage pulse applied in the second stage.SELECTED DRAWING: Figure 10
