Problems solved by technology

Due to the characteristics of the OLED panel, when the OLED panel is controlled for local highlighting, the driving current around the local highlight area is reduced due to the line resistance loss phenomenon in the driving circuit that controls light emission, so that the difference between the highlight area and other areas in the OLED panel A dark band of brightness attenuation appears in the transition area, affecting user experience

Embodiment Construction

[0033] 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.

[0034] In the related art, OLED is a current-type organic light-emitting device, which generates luminescence through the injection and recombination of carriers, and the luminous intensity is proportional to the magnitude of the injected driving current. When using the OLED screen in the terminal to implement a local area highlight mode, it is necessary to increase the current in the ...

Abstract

The invention relates to a brightness adjusting method, a brightness adjusting device and a computer readable storage medium. The brightness adjusting method is applied to the terminal, a display area of a terminal display screen comprises a first display area and a second display area, and the brightness adjusting method comprises the following steps: if a condition for triggering the first display area to perform specified brightness display is determined to be met, obtaining the current gray scale brightness of the second display area. On the basis of the mapping relation between the gray scale brightness of the second display area and the compensation voltage, the compensation voltage corresponding to the current gray scale brightness is determined, the compensation voltage is compensated for the third display area, and the brightness of the third display area is made to be consistent with the brightness of the first display area. The third display area is a transition display area between the first display area and the second display area. According to the invention, the compensation voltage can be determined based on the current gray scale brightness of the second display area, the transition display area between the first display area and the second display area is eliminated, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to the technical field of display screens, and in particular to a brightness adjustment method, a brightness adjustment device, and a computer-readable storage medium. Background technique [0002] Organic light-emitting diodes (organic light-emitting diode, OLED) are also called organic electro-laser displays and organic light-emitting semiconductors. In the related art, the display screen used by the terminal is an OLED display screen. Due to the characteristics of the OLED panel, when the OLED panel is controlled for local highlighting, the driving current around the local highlight area is reduced due to the line resistance loss phenomenon in the driving circuit that controls light emission, so that the difference between the highlight area and other areas in the OLED panel A dark band of brightness attenuation appears in the transition area, affecting user experience. Contents of the invention [0003] In order t...
