Problems solved by technology

[0003] OLED is a current-type device. When the current flows into OLED, the temperature of the display panel rises with the increase of the lighting time, so that the detected voltage value increases and the compensation K value becomes smaller, resulting in scanning during the compensation process.

Abstract

The present disclosure proposes a display control method and device, and a display panel. The display control method includes: acquiring a temperature compensation value of a row of pixel units in a display panel on which temperature compensation is currently performed; acquiring, according to the temperature compensation value, a brightness ratio corresponding to the temperature compensation value; and compensating for brightness of a row of pixel units in the display panel on which temperature compensation is not performed according to the brightness ratio.

Description

technical field [0001] The present invention relates to the technical field of electrical appliances, in particular to a display control method, device and display panel. Background technique [0002] The Organic Light-Emitting Diode (OLED) display panel has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast ratio, low power consumption, and extremely high response speed. [0003] OLED is a current-type device. When the current flows into OLED, as the lighting time increases, the temperature of the display panel also rises, so that the detected voltage value increases, and the compensation K value becomes smaller, resulting in scanning during the compensation process. The boundary affects the display effect. The K value is compensated, that is, the compensation coefficient K, and the change of K can represent the change of electron mobility of a thin film transistor (Thin Film Transistor, TFT for short) in the OLED. Specifically, K is ...
