Abstract

The invention discloses a display driving method and device and a display device. The display driving method comprises the following steps: acquiring preset charging data at the beginning of frame scanning; precharging display pixels on a preset row signal line according to the acquired preset charging data; and after precharging the display pixels on the preset row signal line, sequentially charging all the display pixels on the row signal line and charging the display pixels on the current row signal line, precharging the display pixels on the row signal line with a preset number of rows atthe current row signal line interval. The technical proposal of the invention ensures that each row of display pixels of the display device can be precharged, and the brightness of the display deviceis uniform.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving method, a driving device, and a display device. Background technique [0002] Display devices, such as TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display), have become an indispensable product in video products. With the requirement of large size and high resolution of the display device, there are more and more driving circuits of the display device. Therefore, in the case of a fixed scanning time of a frame, in order to ensure the charging time of the display pixels on each row of signal lines , using pre-charging technology to charge the display pixels in advance. [0003] However, the existing pre-charging technology cannot guarantee that the display pixels of each row of signal lines can be pre-charged, and improvement is urgently needed. Contents of the invention [0004] The embodiments of the present ap...
