Abstract

A brightness compensation parameter detection method, a brightness compensation method, a brightness compensation parameter detection device, a brightness compensation device, a display device and a storage medium. The brightness compensation parameter detection method is used for a display panel, the display area of ​​the display panel includes a first area and a second area, the first area includes a plurality of first pixel units arranged in a first array, and the second area includes a first area according to the first area. A plurality of second pixel units arranged in two arrays, the first area and the second area are different areas, and the brightness compensation method includes: selecting a first target area from the first area, and determining the first compensation according to the brightness of the first target area parameters for performing brightness compensation for at least part of the first pixel units in the first area according to the first compensation parameter; and selecting a second target area from the second area, and determining the second compensation parameter according to the brightness of the second target area, Perform luminance compensation according to the second compensation parameter with at least part of the second pixel units used in the second area.

Description

technical field [0001] Embodiments of the present disclosure relate to a brightness compensation parameter detection method, a brightness compensation method, a brightness compensation parameter detection device, a brightness compensation device, a display device, and a storage medium. Background technique [0002] The pixel units located in different areas of the display panel have different distances from the driving circuit, so the voltage drop (IR Drop) on the signal traces will also be different, so that the display panel may have display defects such as uneven display (mura) question. In this case, the brightness of the display panel needs to be compensated. SUMMARY OF THE INVENTION [0003] At least one embodiment of the present disclosure provides a method for detecting a brightness compensation parameter of a display panel. A display area of ​​the display panel includes a first area and a second area, and the first area includes a plurality of first areas arrange...
