Embodiment 1

[0021] This embodiment provides a backlight compensation method, the method is used to control the backlight circuit of the terminal, so as to control the brightness of the warm light and the cold light in the backlight circuit according to the brightness of the ambient light around the terminal, so as to improve the environment of the terminal. The light is compensated for warm light or cold light, figure 1 It is a flow chart of the backlight compensation method in Embodiment 1 of the present invention, such as figure 1 As shown, the method includes the following steps:

[0022] Step 101: Detect the ambient brightness of the terminal;

[0023] In this step, the ambient brightness of the terminal can be acquired through an optical distance sensor built in the terminal, and this step can be performed when the ambient brightness of the terminal changes.

[0024] Step 102: Control the backlight circuit of the terminal to generate cold light or cold light and warm light accordin...

Embodiment 2

[0029] This embodiment further describes the backlight compensation method provided by the present invention by disclosing more technical details.

[0030] The backlight compensation method provided in this embodiment mainly performs the following processing:

[0031] The ambient brightness of the terminal is detected by the built-in optical distance sensor of the terminal, and the ambient brightness is uploaded to the system in grades. According to the requirements of control accuracy, a variety of classification methods with different accuracy can be used;

[0032] Set the different levels of ambient light to correspond to the intensity of different cold and warm light. Specifically, cold light and warm light can also be corresponding to different levels, and two curves of ambient light-cold light and ambient light-warm light are fitted. That is, the cold light curve and the warm light curve; when the external light, that is, the ambient light is strong, the backlight of the...

Embodiment 3

[0036] This embodiment provides a backlight compensation device, which is used to implement the backlight compensation methods provided in Embodiment 1 and Embodiment 2 above, and the device can be set in a terminal, image 3 is a structural block diagram of the backlight compensation device according to Embodiment 3 of the present invention, such as image 3 As shown, the device 30 includes the following components:

Abstract

The present invention provides a backlight compensation method and a device. The method and the device solve the problem in the prior art that according to the conventional backlight adjustment mode, the brightness of the backlight can be adjusted only according to the external light intensity and the external brightness can not be compensated so as to cause the discomfort of a user eye under the backlight of a terminal. The method comprises the steps of detecting the ambient brightness of the terminal; and generating the cold light or the cold light and the warm light through controlling the backlight circuit of the terminal according to the ambient brightness. According to the technical scheme of the invention, the relatively flexible screen backlight is provided for users, so that the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a backlight compensation method and device. Background technique [0002] At present, the backlight adjustment technology of the terminal can adjust the backlight of the terminal screen according to the brightness of the ambient light around the terminal. When the user looks at the terminal, part of the light comes from the backlight of the terminal and enters the user's eyes through the screen, and the other part of the light comes from the outside world. The light is reflected into the user's eyes through the screen of the terminal. However, the existing backlight technology can only adjust the brightness of the screen by adjusting the brightness of the backlight in the case of strong light and dark light. However, due to external The brightness of the light reflected into the human eye cannot be adjusted, resulting in a warmer and dazzling screen display in a strong lig...
