Abstract

The embodiment of the invention discloses a driving method and a driving device of a display panel. The driving method comprises the steps of obtaining a pre-display image data signal; acquiring a random number control signal; performing micro-disturbance processing on the pre-display image data signal according to the random number control signal to obtain a disturbance driving signal; and driving the display panel to display according to the disturbance driving signal. According to the technical scheme provided by the invention, performing micro-disturbance processing on the pre-displayed image data signal according to the random number control signal. Therefore, the pre-display image data signal generates the random change component relative to the original value, and the color richnessof the actual display image of the display panel is increased on the premise of ensuring that the pre-display image of the display panel is not abruptly changed in vision.

Description

technical field

[0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a driving method and a driving device for a display panel. Background technique

[0002] The parameters of the actual display screen of the display panel depend on the pre-display image data signal. Generally, the pre-display image data is converted into a simulated voltage signal or a simulated current signal by the driver chip in the display panel to drive the display panel to realize the display function. The existing above-mentioned driving mechanism makes the color richness of the actual display screen of the display panel only related to the pre-display image data signal. The color richness of the actual display screen has become an urgent problem to be solved. Contents of the invention

[0003] In view of this, an embodiment of the present invention provides a display panel driving method and a driving device, which performs micro-disturban...
