Backlight brightness adjusting method and device and terminal equipment

Abstract

The invention discloses a backlight brightness adjusting method and device and terminal equipment. The method comprises that when an indication to carry out a screen ON operation on the terminal equipment in a screen OFF state is received, whether a photosensitive value, of the present environment, collected by a photosensitive device being re-enabled is obtained is determined; if the photosensitive value of the present environment is not obtained, the backlight brightness value of the screen of the terminal equipment is set as a first backlight brightness value before the screen is OFF temporarily; when the photosensitive value, reported by the photosensitive device, of the present environment is received, a second backlight brightness value corresponding to the photosensitive value of the present environment is determined; and if the difference between the second backlight brightness value and the first backlight brightness value is greater than a preset threshold, a preset first backlight adjusting interface is called, the backlight brightness value of the screen is adjusted to the second backlight brightness value in preset first time period, and the first time period is shorter than a second time period corresponding to a second backlight adjusting interface. The method can be used to shorten adjusting time of the screen backlight brightness, and improve user experience.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment manufacturing, in particular to a backlight brightness adjustment method, device and terminal equipment. Background technique [0002] Generally, a terminal device (for example, a smart phone) can turn on an automatic backlight mode, so that the brightness of the screen backlight of the terminal device can self-adjust according to changes in current ambient light. [0003] In the related technology, the terminal equipment with automatic backlight mode can continuously read the light-sensing value of the current environment from the light-sensing device, and calculate the currently required brightness value of the screen backlight according to the light-sensing value, so as to realize the The function of automatically changing the screen backlight. If the light-sensing brightness changes greatly, in order to enhance the user experience and protect the hardware of the terminal de...

Problems solved by technology

Then, when the ambient light before the user’s screen was turned off last time and when the screen is turned on this time is quite different, according to the above logic, the brightness value of the screen this time will be the brightness value before the screen is turned off, and the screen brightness change generally takes 5 to 10 seconds, so the user will feel that the screen brightness is quite different from the current environment, and even cannot be used normally in a short period of time (5 to 10 seconds).
