Abstract
(EN)
A driving method for a display panel (600), comprising: performing square wave conversion on driving data received by each channel, so as to obtain data line signals, square wave signals generated by different grayscale conversions in corresponding driving data having the same high level and different low level output time. Also disclosed are a driving device (100) and a display device (500), comprising: a receiver (200), for receiving driving data corresponding to each channel; a square wave conversion chip (300), for performing square wave conversion on the driving data to obtain data line signals; and an outputter (400), for outputting the data line signal corresponding to the each channel, transmitting same to a corresponding data line on the display panel (600), and performing data driving on the display panel (600), wherein, in the square wave conversion chip (300), square wave signals generated by different grayscale conversions in corresponding driving data have the same high level and different high level output time.
