Problems solved by technology

LED display screens are all calibrated to the same brightness when they leave the factory, but in practical applications, due to the influence of different light intensities, the visual experience of different areas of the same display screen will also be different; In the case of screens, the different angles of sunlight will directly lead to different light intensities received by different areas. Places with high light intensity will give people a dim feeling, while places with low light intensity will give people a dazzling feeling.

Abstract

The embodiment of the invention discloses a display screen brightness adjustment method and device. The illumination data of each independently controlled display area are acquired. Based on the illumination data of independently controlled display area, and a preset illumination and brightness scale relation table, the brightness ratio of each independently controlled display area is determined. The brightness of each independently controlled display area is correspondingly adjusted according to the brightness ratio of each independently controlled display area. According to the embodiment of the invention, the phenomenon of deteriorated human eye viewing effect caused by uneven illumination in the LED display industry is improved, and consistent human eye subjective feeling in the case of uneven illumination is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and device for adjusting brightness of a display screen. Background technique [0002] Due to the popularization of LED display applications, its application in various large-scale occasions is increasing, and people's requirements for its display quality are also getting higher and higher. LED display screens are all calibrated to the same brightness when they leave the factory, but in practical applications, due to the influence of different light intensities, the visual experience of different areas of the same display screen will also be different; In the case of screens, the different angles of sunlight will directly lead to different light intensities received by different areas. Places with high light intensity give people a dim feeling, while places with low light intensity give people a dazzling feeling. [0003] Therefore, how to alleviate the visual differen...
