Problems solved by technology

However, the uneven brightness of the screen, that is, the Mura phenomenon, is a common bad phenomenon in OLED display technology. This bad phenomenon is mainly caused by the difference in the characteristics of each TFT caused by the immature process of the TFT (Thin Film Transistor) in the screen.

Embodiment Construction

[0045] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

[0046] At present, the commonly used method to eliminate the uneven brightness of the screen, that is, the Demura compensation method, is to use a high-resolution and high-precision CCD (Charge-coupled Device, Charge-coupled Device) camera to shoot several gray-scale images, and then according to the camera. The data analysis displays the pixel color distribution characteristics in the screen, and ...

Abstract

The invention relates to a screen brightness adjusting method and device and a computer readable storage medium. The method comprises: obtaining an original compensation multiple used for eliminating uneven screen brightness and at least one set of correction compensation multiple corresponding to the original compensation multiple are acquired; in response to a received display parameter switching instruction for the screen, obtaining current display parameter information of the screen; determining a target compensation multiple from the original compensation multiple and the at least one group of correction compensation multiple according to the current display parameter information; and adjusting the brightness of the screen according to the target compensation multiple. According to the technical scheme, the determined target compensation multiple adapts to the current display parameter information of the screen, the screen adjusting effect can be improved, and the uniformity of screen brightness is improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a method, a device, and a computer-readable storage medium for adjusting screen brightness. Background technique [0002] OLED (Organic Light-Emitting Diode), as a current-type light-emitting device, has been increasingly used in high-performance display screens. Crystal Display) display technology has the advantages of high contrast, ultra-thin, and bendable. However, the uneven brightness of the screen, that is, the Mura phenomenon, is a common bad phenomenon in OLED display technology. This bad phenomenon is mainly caused by the difference in the characteristics of each TFT caused by the immaturity of the TFT (Thin Film Transistor) process in the screen. . SUMMARY OF THE INVENTION [0003] In order to overcome the problems existing in the related art, the present disclosure provides a screen brightness adjustment method, device and computer-readable storage ...
