Problems solved by technology

[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[0003] With the improvement of frame rate and display grayscale requirements, the traditional scanning algorithm is no longer applicable, and the concept of sub-field has been applied to various digital drive algorithms.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

Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0052] Just like the background technology, with the improvement of frame rate and display grayscale requirements, the traditional scanning algorithm is no longer applicable, and the concept of sub-field has been applied to various digital driving algorithms. The scanning algorithm of sub-field scanning currently used Insufficient time leads to insufficient data storage and dark display images. The specific analysis is as follows:

[0053] The scanning time in the current sub-field scanning algorithm is inversely ...

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 steps of dividing a frame into n sub-frames, and dividing the display period of the frame into m sub-display periods; dividing the display panel into a plurality of subspaces; wherein the subspace number isgreater than the row number of the display panel; obtaining a sub-display period of each data bit in each sub-space 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 sub-space number, a row number and each data bit; obtaining a scanning sequence according to the corresponding relation and providing ascanning signal for the display panel according to the scanning sequence; and performing data recombination on each row of data, and providing a data signal to the display panel according to the recombined data to drive the display panel to display. Through the technical scheme of the invention, the scanning time of each data bit is increased while the data driving of the display panel is realized.
