Driving method of display panel, driving device of display panel and display device

Abstract

The embodiment of the invention discloses a driving method of a display panel, a driving device of the display panel and a display device. The driving method of the display panel comprises the following steps: setting the initial position of each sub-frame in a corresponding sub-display period based on the weight of a data bit; obtaining a sub-display period of each data bit in each row of the display panel in a display period of one frame based on the weight of the data bit so as to obtain a corresponding relationship among time, a row number and each data bit; obtaining a scanning sequence according to the corresponding relation and providing a scanning signal for the display panel according to the scanning sequence; and performing data recombination on each row of data, and providing adata signal to the display panel according to the recombined data to drive the display panel to display. By means of the technical scheme, data driving of the display panel is achieved, meanwhile, thescanning time of all the data bits is prolonged, the problem that a display image is dark is solved, and the resolution ratio of the display panel can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display, and in particular to a method for driving a display panel, a driving device thereof, and a display device. Background technique [0002] At present, the light-emitting system mainly includes two driving modes, analog drive and digital drive, in terms of gray scale realization. To adjust the luminance of light-emitting devices, analog signals are easily mixed with noise, and it is difficult to achieve high-precision control of the display gray scale of light-emitting devices. However, digital driving circuits are more and more widely used because of their low image noise and fast switching speed. [0003] With the improvement of frame rate and display grayscale requirements, the traditional scanning algorithm is no longer applicable, and the concept of sub-field has been applied to various digital drive algorithms. The scanning time of the currently used sub-field scanning algorithm is...

[0002] At present, the light-emitting system mainly includes two driving modes, analog drive and digital drive, in terms of gray scale realization. To adjust the luminance of light-emitting devices, analog signals are easily mixed with noise, and it is difficult to achieve high-precision control of the display gray scale of light-emitting devices. Digital drive circuits are more and more widely used due to their low image noise and fast switching speed.

[0003] With the improvement of frame rate and display grayscale requirements, the traditional scanning algorithm is no longer applicable, and the concept of sub-field has been applied to various digital drive algorithms. The scanning time of the currently used sub-field scanning algorithm is insufficient, and further Insufficient data storage leads to dark display images
