Problems solved by technology

[0003] In the field of display technology, the International Commission on Illumination (CIE) has formulated a standard of Gamma=2.2, but Gamma=2.2 is obtained through experiments in a darker environment, and does not take into account bright environments, such as When there is light or in a bright office environment, in addition to the brightness formed by the display itself, the display will also reflect the ambient light in the bright environment. Therefore, the Gamma value of the display is fixed at 2.2, which cannot meet the requirements of the bright environment. The display effect is easy to reduce the sense of layering and comfort perceived by the human eye

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] see figure 1 , an embodiment of the method for performing Gamma compensation on a display in the present invention includes:

[0023] Step S101: Obtain the brightness value of the display in the first environment and the brightness value of the ambient light reflected by the screen surface of the display in the second environment, respectively. The first environment is an environment where the display does not generate ambient light reflection;

[0024] In a bright environment, such as when there is light or in a bright office environment, the reflected light between objects (such as walls or desks, etc.) The sum of the light is called the ambient light. In this embodiment, the first environment is that the display is in an environment that does not generate ambient light reflection, such as a dark environment, and the second environment is t...

Abstract

The invention discloses a method of Gamma compensation towards a display device and a device of Gamma compensation. The compensation method comprises: a brightness value when the display device is displayed under a first environment and a brightness value when ambient light is reflected of a display device screen surface under a second environment are respectively obtained. One Gamma composite value is fitly obtained according to the brightness value when the display device is displayed under the first environment and the brightness value when ambient light is reflected of the display device screen surface under the second environment. Brightness when the display device is displayed is adjusted according to the Gamma composite value. According to the method of Gamma compensation towards the display device and the device of Gamma compensation, display accuracy under the condition of the ambient light of the display device can be improved, thus layer sense and comfortable degree of human eyes perception are improved.

Description

technical field [0001] The present invention relates to the technical field of display, in particular to a method for performing Gamma compensation on a display and a Gamma compensation device. Background technique [0002] Gamma is a parameter of the display, derived from the response curve of the display, which characterizes the nonlinear relationship between the display brightness of the display and the input voltage. The same image may appear different on different monitors, which mainly depends on the size of Gamma. [0003] In the field of display technology, the International Commission on Illumination (CIE) has formulated a standard of Gamma=2.2, but Gamma=2.2 is obtained through experiments in a darker environment, and does not take into account bright environments, such as When there is light or in a bright office environment, in addition to the brightness formed by the display itself, the display will also reflect the ambient light in the bright environment. Ther...
