Abstract

A luminance adjusting method for a display screen of an electronic device includes the following steps. Firstly, a current brightness value and a current imaging color value of the display screen are recorded. In response to the user's operation, the light output of the display screen is adjusted. Consequently, the adjusted brightness value is equal to a default brightness value and the adjusted imaging color value is equal to a default imaging color value. Meanwhile, the display screen is operated in the healthy display mode. In response to the user's additional operation, the light output of the display screen is adjusted. Consequently, the adjusted brightness value is equal to the recorded current brightness value and the adjusted imaging color value is equal to the recorded current imaging color value. Meanwhile, the display screen is restored to the normal display mode.

Dependent claims

A luminance adjusting method for a display screen of an electronic device, the luminance adjusting method comprising steps of:

storing a default brightness value and a default imaging color value;
recording a current brightness value and a current imaging color value of the display screen in response to an activating operation;
adjusting a light output of an illumination module of the display screen in response to a triggering operation, so that an adjusted brightness value of the display screen is equal to the default brightness value and an adjusted imaging color value of the display screen is equal to the default imaging color value;
and
adjusting the light output of the illumination module of the display screen in response to an additional triggering operation, so that the adjusted brightness value of the display screen is equal to the recorded current brightness value and the adjusted imaging color value of the display screen is equal to the recorded current imaging color value, wherein the default brightness value is lower than the current brightness value, and the default imaging color value is lower than the current imaging color value.
