AI Technical Summary

Technical Problem

OLED displays do not provide ideal brightness and contrast in high-brightness environments, failing to meet the visibility requirements of the displayed content.

Method used

By calculating the average image level of the image to be displayed, the peak brightness compensation mode is activated. The adjusted brightness is determined based on the average image level, and the brightness is dynamically adjusted by interpolation using a gamma curve to improve the display brightness and contrast.

Benefits of technology

Significantly improves the display brightness and dynamic contrast range of OLED displays in high-brightness environments, thereby enhancing the display quality of content.

Abstract

The present disclosure relates to a display brightness control method and device, a display device and an electronic device. The method comprises: calculating an average image level of a to-be-displayed image, the average image level of the to-be-displayed image being used to represent overall brightness of the to-be-displayed image; in a case where a peak brightness compensation mode is started, determining an adjusted brightness of the to-be-displayed image based on the average image level of the to-be-displayed image; and displaying the to-be-displayed image based on the adjusted brightness of the to-be-displayed image. According to the embodiments of the present disclosure, the brightness of the to-be-displayed image can be adjusted in the peak brightness compensation mode, so as to improve the display brightness and enhance the dynamic contrast range of the to-be-displayed image, and improve the display quality of the display content.
