Abstract

The invention discloses a gamma compensation method, device and equipment and a medium. The gamma compensation method comprises the following steps: taking an area of a display screen as a reference area, and performing gamma debugging on the reference area to meet a target gamma curve; for one or a plurality of areas outside the reference area, performing measuring to obtain a first gamma curve of the region and a second gamma curve of the reference region, and determining a compensation value of the region according to the deviation between the first gamma curve and the second gamma curve, so that the compensated gamma curve of the region is consistent with the second gamma curve. According to the scheme provided by the embodiment of the invention, the area outside the reference area iscompensated, so the gamma curve is consistent with the gamma curve of the reference curve, and the uniformity of the display screen is improved.

Description

technical field [0001] The embodiments of the present application relate to display technology, especially to a gamma compensation method, device and equipment, and a medium. Background technique [0002] Large-size screens such as (vehicle, NB (NoteBook, notebook)), etc., due to the large screen size, IR Drop (IR voltage drop) will be very serious, making it difficult for the brightness uniformity or chromaticity uniformity of the screen to meet the specifications. Contents of the invention [0003] Embodiments of the present application provide a gamma compensation method, device, equipment, and medium to improve screen uniformity. [0004] The embodiment of the present application provides a gamma compensation method, including: [0005] Taking an area of ​​the display screen as a reference area, and performing gamma adjustment on the reference area to meet the target gamma curve; [0006] For one or more areas outside the reference area, measure the first gamma curve...
