Problems solved by technology

[0002] Since the AMOLED (Active-Matrix Organic Light-Emitting Diode, active-matrix organic light-emitting diode) screen is driven by current, it is sensitive to the uniformity of the process. In low-brightness or low-gray-scale scenes, the overall current of the screen is small , leading to different currents of luminescent materials, the chromaticity and brightness of the AMOLED screen are uneven, and mura phenomenon is prone to occur. This uneven display problem is especially prominent when a large area of ​​pure color screen or the same background is displayed, which seriously affects the screen display effect.

Embodiment Construction

[0073] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0074] Before implementing the embodiments of the present disclosure, the nouns involved in the present disclosure are explained first.

[0075] mura phenomenon: uneven brightness and chromaticity of the screen.

[0076] Demura function: A method for compensating for the non-uniformity of brightness or chromaticity of the screen when displaying images with low brightness or low graysc...

Abstract

The invention relates to a screen display method and a device, belonging to the technical field of terminals. The method comprises the following steps: judging whether the screen satisfies the demurafunction opening condition; When it is determined that the screen satisfies the demura function opening condition, the demura function is turned on; Based on the demura function turned on, the brightness value of each pixel point in the picture to be displayed is compensated to obtain the actual brightness value of each pixel point. The picture to be displayed is displayed according to the actualbrightness value of each pixel point. When it is determined that the screen satisfies the demura function turning on condition, the demura function is turned on, and the brightness value of each pixelpoint is compensated, thereby improving the screen display effect. Since the demura function can be turned on selectively, the demura function is turned on only when the demura function needs to be turned on, so that the display effect is guaranteed, and the power consumption caused by turning on the demura function is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a screen display method and device. Background technique [0002] Since the AMOLED (Active-Matrix Organic Light-Emitting Diode, active-matrix organic light-emitting diode) screen is driven by current, it is sensitive to the uniformity of the process. In low-brightness or low-gray-scale scenes, the overall current of the screen is small , leading to different currents of luminescent materials, the chromaticity and brightness of the AMOLED screen are uneven, and mura phenomenon is prone to occur. This uneven display problem is especially prominent when a large-area solid-color screen or the same background is displayed, which seriously affects the screen display effect. . [0003] In order to improve the display effect of the screen, related technologies can pre-store the brightness compensation information of each pixel on the AMOLED screen in an external Flash IC ...
