AI Technical Summary

Technical Problem

The brightness attenuation caused by environmental factors in OLED display panels leads to brightness attenuation. The prior art is difficult to effectively solve this problem, resulting in the continuous decrease in brightness of the display panels during the accumulation of use time.

Method used

By predicting the brightness attenuation curve based on the initial display brightness, the brightness of the display panel after different attenuation times is predicted, and the initial brightness and attenuation time are continuously updated until the cumulative attenuation time reaches the set threshold, and the brightness compensation value is calculated for brightness compensation.

Benefits of technology

It reduces the cumulative error of brightness compensation, improves the accuracy of brightness compensation, and extends the normal service life of the OLED display panel.

Abstract

The embodiments of the present disclosure provide a brightness compensation method and device, an electronic device, a display panel, and a storage medium. The brightness compensation method includes: determining the predicted display brightness of the display panel after the brightness decays for a decay time based on the brightness decay curve corresponding to the initial display brightness of the display panel, determining the cumulative decay time based on the decay time of the display panel, updating the initial display brightness based on the predicted display brightness, and updating the decay time based on the updated initial display brightness; repeating the above steps until the cumulative decay time reaches a set time threshold, and determining the brightness compensation value of the display panel based on the current predicted display brightness. The embodiments of the present disclosure can improve the accuracy of brightness compensation.
