Embodiment Construction

[0020] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0021] A point on the display that the eyes see is a pixel, which is composed of three sub-pixels of red, green, and blue. For each sub-pixel, the light source behind it can show different brightness, that is, every pixel on the screen The brightness changes are all caused by the grayscale changes of the RGB three sub-pixels that make up the pixel. The gray scale represents the different brightness levels from the darkest brightness to the brightest brightness. The more brightness levels, the more delicate the picture can be presented; taking an 8bit display panel (Panel) as an example, it can express 8 times of 2 Square brightness level, called 256 gray scale.

[0022] In the technical parameters of the display, the contrast ratio refers to the value o...

Abstract

The invention provides a method and electric equipment for adjusting brightness of a display. The display comprises pixels, each pixel is provided with a corresponding light source which has a Gamma value, and the Gamma values are in positive correlation with the brightness of the light sources. The method includes the steps that a standard Gamma curve for adjusting the brightness of the display is obtained; all application scenes of the display are obtained; in each application scene, the display is used for processing pictures needing displaying by the application scene, an application Gamma curve is set up for at least one application scene, and the application Gamma curve deviates from the standard Gamma curve. The gray scale brightness output by the display is adjusted by adjusting the Gamma curves according to the needs for processing pictures, input picture data can be analyzed without depending on a hardware circuit, the brightness output by the display can be matched with display content, and the better display effect is achieved.

Description

technical field [0001] The invention relates to display technology, in particular to a method and electronic equipment for adjusting the brightness of a display. Background technique [0002] The screen of the mobile terminal uses a fixed grayscale and three primary colors (RGB) Gamma. The Gamma value is represented by a curve, which indicates the eye's sensitivity to light. In the process of displaying different scenes, the same Gamma curve is used to adjust the grayscale. Brightness, does not adjust for scene changes. [0003] The existing technology for dynamically adjusting Gamma requires the use of hardware circuits to analyze input image data and adjust the Gamma curve according to the analysis results. If the application scenarios are different, different images require different Gamma curves. [0004] The existing technology has the following problems: in the existing technology of dynamically adjusting Gamma, it is difficult to update the analysis algorithm, which ...
