Abstract
A method for acquiring luminance compensation data, which includes: collecting an image of a first grayscale value and an image of a second grayscale value displayed by a display panel to be compensated; calculating a luminance difference between the image of the first grayscale value and image of the second grayscale value for each display unit of the display panel; determining a target luminance difference based on the luminance difference between the image of the first grayscale value and the image of the second grayscale value for each display unit; determining a preset compensation data calculation scheme corresponding to the display panel and acquiring images of grayscale values required by the preset compensation data calculation scheme, based on a preset condition that the target luminance difference meets; and determining the luminance compensation data for the display panel, based on the determined images of grayscale values.
