Problems solved by technology

[0003] The terminal devices in the prior art all include a display screen, and the terminal device can adjust the backlight brightness value of the display screen according to the brightness value of the ambient light, but the adjustment process of the backlight brightness value is when the display screen is on. In other words, this process must be completed when the backlight is turned on, which leads to the technical problem of high power consumption during the backlight adjustment process, and the user can watch the backlight adjustment process, making the user's Low user experience

Abstract

The invention provides a display brilliance control method and an electronic device; the method comprises the following steps: obtaining a first environment brightness value of a first electronic device environment; obtaining a second display luminance value corresponding to the first environment brightness value according to a corresponding relation between the environment brightness value and the display luminance value; finally adjusting a present display luminance value to the second display luminance value from a first display luminance value, wherein the first and second display luminance values are different display luminance values, so the electronic device cannot adjust backlight when the display is lit up, thus reducing electronic device power consumption, and improving usage time of the electronic device.
