Problems solved by technology
Since displaying different gray scales requires different driving voltages, the charging rate of the pixel circuit in different gray scales is also inconsistent. Such inconsistency results in poor brightness uniformity under different gray scales, which affects the subjective experience of display.

Embodiment Construction
[0041] 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 herein 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, the drawings only show some but not all structures related to the present invention.
[0042] As described in the Background Art, since different driving voltages are required for displaying different gray levels, the charging rates of the pixel circuits in different gray levels are also inconsistent. Such inconsistency results in poor uniformity of luminance under different gray levels. The inventor found that the reason for the above problem is that the existing display panel usually includes a plurality of pixel circuits. When driving the pixel circuits, it usually includes an initialization stage and a data writi...

Embodiments of the present invention disclose a driving method, a driving device, and a display device for a display panel, wherein the driving method includes dividing a maximum gray stage displayed by the display panel into a plurality of sub-gray stages, and displaying a display according to each gray level in the sub-gray stage. The panel outputs the corresponding data signal to drive the display panel to display in the corresponding sub-gray stage, adjust the reference signal output to the display panel and corresponding to a single sub-gray stage to obtain multiple uniform brightness values corresponding to the sub-gray stage, and obtain the corresponding The reference signal of the maximum brightness uniform value among the multiple brightness uniform values; according to the reference signal corresponding to the maximum brightness uniform value, the display panel is driven to display in the corresponding sub-gray stage, thereby ensuring that the pixel circuit is displayed in each sub-gray stage. The charging rate is larger and the luminance uniformity value is larger, thereby narrowing the difference between the luminance uniformity values of different grayscales, thereby improving the display uniformity of the display panel under different grayscales, and improving the display effect.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a driving method, a driving device and a display device for a display panel. Background technique [0002] With the development of display technology, the requirements for the quality of display images are also getting higher and higher. [0003] With the increase of display size and the improvement of display resolution, the number of pixel circuits in the display screen is increasing. Since different driving voltages are required for displaying different gray scales, the charging rates of the pixel circuits in different gray scales are also inconsistent. Such inconsistency results in poor uniformity of brightness under different gray scales, which affects the subjective experience of display. SUMMARY OF THE INVENTION [0004] The present invention provides a driving method, a driving device and a display device for a display panel, so as to impr...
