Screen display method and device

Abstract

The present disclosure relates to a screen display method and device, and belongs to the technical field of terminals. The method includes: obtaining the maximum brightness value of the screen under specified conditions; determining the target brightness difference value of the screen according to the maximum brightness value and the initial brightness value; , determine the target chromaticity difference corresponding to the target luminance difference; compensate the chromaticity value of each pixel on the screen according to the target chromaticity difference; perform screen display based on the compensated chromaticity value of each pixel . This disclosure obtains the target luminance difference value of the screen, and according to the corresponding relationship between the luminance difference value and the chromaticity difference value, obtains the target chromaticity difference value corresponding to the target luminance difference value, and calculates each pixel based on the target chromaticity difference value. The chromaticity value of each pixel is compensated, and then the screen display is performed according to the compensated chromaticity value of each pixel. By adopting this method, the chromaticity of the screen is kept consistent, and the display effect is improved.

Description

Technical field[0001]The present disclosure relates to the field of terminal technology, and in particular to a screen display method and device.Background technique[0002]Limited by the process, AMOLED (Active-Matrix Organic Light-Emitting Diode, active matrix organic light-emitting diode) screen as the screen lighting time increases, the efficiency of the luminescent material will decrease, making the screen brightness attenuation, The white pixels on the screen turn yellow, resulting in poor chromaticity consistency on the AMOLED screen.[0003]However, at present, it is generally only possible to calibrate the AMOLED screen with a special optical calibration device before the AMOLED screen leaves the factory, and the AMOLED screen cannot be calibrated during the use of the AMOLED screen. As the AMOLED screen is used for longer, the screen display effect becomes better. It's getting worse. Therefore, in order to improve the display effect of the AMOLED screen, a screen display metho...

Problems solved by technology

[0002] Restricted by the manufacturing process, AMOLED (Active-Matrix Organic Light-Emitting Diode, active-matrix organic light-emitting diode) screen will decrease the efficiency of the light-emitting material as the screen lighting time increases, causing the brightness of the screen to attenuate. The color of the white pixels on the screen turns yellow, resulting in poor chromaticity consistency of the AMOLED screen

[0003] However, at present, the AMOLED screen can only be calibrated with special optical calibration equipment before the AMOLED screen leaves the factory, and the AMOLED screen cannot be calibrated during the use of the AMOLED screen. getting worse
