Abstract

The invention relates to a compensation data compression method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the data partitioning of to-be-compressed compensation data corresponding to a display region, and obtaining compensation data blocks corresponding to a plurality of display subregions; converting the compensation data blocks corresponding to the plurality of display sub-regions from a spatial domain to a frequency domain to obtain a plurality of first feature points; based on a preset compression ratio, compressing the plurality of first feature points to obtain a plurality of second feature points; and determining compressed compensation data corresponding to the display area based on the plurality of second feature points. According to the embodiment of the invention, the data volume of the compressed compensation data for performing brightness uniformity compensation on the display area can be effectively reduced.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a compensation data compression method and device, electronic equipment, and a storage medium. Background technique [0002] Light-Emitting Diode (Light-Emitting Diode, LED) display screens and Organic Light-Emitting Diode (Organic Light-Emitting Diode, OLED) display screens are widely used in the field of screen display. However, in the production process of LED screens and OLED screens, it is difficult to ensure the consistency of the luminous efficiency of all lamp beads on the display screen. figure 1 A schematic diagram of the display brightness of the display screen in the related art is shown. Such as figure 1 As shown, due to the inconsistent luminous efficiency of different lamp beads on the display screen, the brightness displayed in the entire display area of ​​the display screen is uneven. Therefore, it is necessary to perform brightness uniformity c...
