Abstract

A brightness compensation method is applied to a display panel, and a temperature sensor and a light-emitting element are arranged on the display panel. The brightness compensation method comprises the steps of: acquiring an environment temperature signal collected by the temperature sensor; and performing brightness compensation on the light-emitting element according to the environment temperature signal and at least one brightness compensation factor.

Description

technical field [0001] This article relates to but not limited to display technology, especially a brightness compensation method, a display panel and a display device. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) devices have attracted more attention due to their characteristics of active light emission, high luminous brightness, high resolution, wide viewing angle, fast response speed, low energy consumption and flexibility. . However, when OLED devices are operated at high or low temperatures, color shift may occur. For example, in the low-temperature (-20°C) reliability test of OLED display panels, it was found that the color cast of the white screen at the front viewing angle turned yellow, and the color cast at low temperature made the OLED display produce a bad customer experience and reduced the competitiveness of the product. Contents of the invention [0003] The following is an overview of the...
