Embodiment Construction

[0023] 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.

[0024] As described in the background art, when adjusting the display brightness of an existing display device, a sudden change in display brightness, that is, a screen splash phenomenon, generally exists. The inventors found that the reason for the above problems is that in order to optimize the performance of the display device, the driving voltage of the display device can be set so that the display device can be driven by different driving voltages under different display brightness. Exemplarily, the driving voltage may includ...

Abstract

Embodiments of the present invention disclose a driving device and a driving method for a display panel, and a display device. The drive device of the display panel includes: a drive voltage adjustment module and a display brightness compensation module, the drive voltage adjustment module is electrically connected with the display brightness compensation module; the drive voltage adjustment module is used for adjusting the drive voltage of the display panel according to the interval to which the display brightness level belongs, And, in the compensation stage, the display brightness level and its corresponding driving voltage and display brightness value are transmitted to the display brightness compensation module; the display brightness compensation module is used to compensate the display brightness value in the compensation stage, so that the display panel is in different The display brightness values ​​corresponding to adjacent display brightness levels under the driving voltage are continuous; wherein, the driving voltages corresponding to different display brightness level intervals are different; the driving voltage includes at least one of a power supply voltage and an initialization voltage. The technical solutions of the embodiments of the present invention help to alleviate the screen splash phenomenon of the display device.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a driving device and a driving method of a display panel, and a display device. Background technique [0002] With the development of display technology, people have higher and higher requirements for the performance of display devices. At present, when an existing display device adjusts the display brightness, a sudden change of display brightness, that is, a screen splash phenomenon, is common, which not only affects the display effect, but also reduces the user experience. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a driving device and a driving method for a display panel, and a display device, so as to alleviate the screen splash phenomenon of the display device. [0004] In a first aspect, an embodiment of the present invention provides a drive device for a display panel, including: a drive voltage adjust...
