Embodiment Construction

[0032] Embodiments of the present invention provide a method, device, and electronic device for adjusting the brightness of the backlight, which are used to adjust the brightness of the backlight of the display screen according to the ambient light intensity while taking into account the power consumption of the electronic device and the user's human visual experience. The general idea of ​​the solution is as follows:

[0033] After the electronic device obtains the ambient light illuminance value through the ambient light sensor, it determines the backlight luminance corresponding to the ambient illuminance value according to the backlight brightness adjustment curve and the ambient illuminance value determined based on the brightness reference value and the corresponding relationship between the ambient illuminance and the backlight luminance Adjust the value, and adjust the backlight brightness of the display screen of the electronic device according to the backlight brightne...

Abstract

The invention provides a method and device for adjusting the backlight brightness, and electronic equipment. The method comprises the following steps: obtaining an environment light illuminance valuethrough an environment sensor; determining a backlight brightness adjustment value corresponding to the environment light illuminance value according to a backlight brightness adjustment curve and theenvironment light illuminance value, wherein the backlight brightness adjustment curve is determined based on the corresponding relation among a brightness reference value, the backlight brightness adjustment curve and the backlight brightness; and adjusting the backlight brightness of a display screen of the electronic equipment according to the backlight brightness adjustment value. The methodachieves the adjustment of the backlight brightness of the display screen according to the environment light illuminance with the consideration to the power consumption of the electronic equipment andthe sense of the eyes of a user.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method, device and electronic equipment for adjusting the brightness of a backlight. Background technique [0002] Ambient light sensor is already a standard configuration of electronic devices such as smartphones, tablets, laptops, smart TVs, multimedia players, etc. One of its most important functions is to sense the light conditions of the environment where the electronic device is located and inform the processor, Based on the mapping curve of ambient light and backlight preset by the electronic device manufacturer or application developer, the brightness of the backlight of the display is automatically adjusted, thereby reducing the power consumption of the product. This is a method for saving power consumption. [0003] In the prior art, there is no reasonable solution for adjusting the brightness of the backlight of the display screen according to the ambient light i...
