DRIVING METHOD, DRIVING DEVICE AND DISPLAY DEVICE

WIPO Patent Application WO/2016/201786

A1

Disclosed are a driving method, driving device (10) and display device. The driving method is used for driving a display panel (15), and the driving method comprises outputting a scanning drive signal to each of scan lines in the display panel (15), wherein the scanning drive signal comprises several frame signals distributed periodically, and each of the frame signal comprises: a first voltage for maintaining each of the scan lines to be strobed during a first time period, the first voltage being a first high level DC voltage (Vgh); a second voltage (Vgl) for maintaining each of the scan lines to be turned off during a second time period, the second voltage (Vgl) being an AC voltage, and being a second low level voltage (Vgl1) and a second high level voltage (Vgl2) alternatingly outputted, wherein the first high level voltage (Vgh) is greater than the second high level voltage (Vgl2). By changing the second voltage (Vgl) for maintaining the scan lines to be turned off to the second low level voltage (Vgl1) and the second high level voltage (Vgl2) alternatingly outputted, the present invention can effectively improve the variation of a leakage current of a TFT in the display panel (15), thereby improving an image retention phenomenon occurred in the display device, and the driving method is easy.
