Problems solved by technology

The disadvantage of this method is that the relationship between the ambient brightness and the backlight brightness setting value is a preset fixed value
Such an adjustment method can only switch between different brightness values ​​mechanically, which cannot meet the usage habits and needs of different users.

Embodiment Construction

[0021] see figure 1 , figure 1 It is a flowchart of a backlight control method provided by an embodiment of the present invention. As shown in the figure, the backlight control method of this embodiment includes the following steps:

[0022] S101: When the user turns off the automatic backlight, collect the ambient light brightness, and at the same time acquire the backlight value set by the user under the ambient light brightness.

[0023] Wherein, before executing the method of the embodiment of the present invention, a preset step is further included, preset a plurality of ambient light brightness intervals, a backlight value adjustment range corresponding to each interval, and a sampling threshold for each interval.

[0024] In the specific implementation, the ambient light is divided into multiple intervals, from dark to bright, such as 0-20, 20-40, 40-60, 60-80, 80-100..., and the last interval is greater than a certain threshold ( Such as 1000nit). The adjustment ran...

Abstract

The invention discloses a backlight control method and an electronic device. The backlight control method includes the following steps that: when a user disables automatic backlight, environmental light brightness and a backlight value which is set by the user under the environmental light brightness are acquired continuously; relations between the environmental light brightness and backlight brightness values are established with the acquired environmental light brightness and the backlight value which is set by the user under the environmental light brightness; and when automatic backlight is enabled, backlight brightness is automatically adjusted according to the relations between the environmental light brightness and backlight brightness values. With the above backlight control method adopted, automatic backlight control can adapt to use habits of different users.

Description

technical field [0001] The invention relates to a backlight control method and electronic equipment. Background technique [0002] Electronic devices with display screens (such as mobile phones, notebook computers, pads, etc.) are often provided with a backlight brightness adjustment function. With the gradual intelligentization of electronic equipment, the brightness adjustment of the backlight can also realize intelligent adjustment. [0003] For example, the current automatic backlight control of electronic equipment: the system periodically acquires the brightness of the environment, and then uses the preset relationship between the environment brightness and the backlight brightness setting value to set the backlight of the electronic equipment. The disadvantage of this method is that the relationship between the ambient brightness and the set value of the backlight brightness is a preset fixed value. Such an adjustment method can only switch between different brightn...
