Embodiment Construction

[0040] see figure 1 , which is a block diagram of the automatic screen brightness adjustment system of the present invention. In the figure, the automatic screen brightness adjustment system 1 of the present invention is applicable to a handheld electronic device 2 . The screen brightness automatic adjustment system 1 includes a photosensitive module 11 , a conversion module 12 , a setting module 13 , a memory module 14 , a processing module 15 and a backlight control module 16 . The photosensitive module 11 is used to sense a plurality of ambient light sources, and generate an analog brightness value according to each ambient light source. The conversion module 12 can be connected to the photosensitive module 11 to receive each analog brightness value and convert each analog brightness value into a digital brightness value. The setting module 13 is for the user to set a set brightness value according to each ambient light source. The memory module 14 is used to store each ...

Abstract

The invention discloses a screen brightness automatic adjustment system and a method thereof. In the system disclosed by the invention, a photosensitive module is used to sense a plurality of ambient light sources and generate a plurality of analog brightness values; a conversion module is used to covert each analog brightness value to a digital brightness value; a setting module is used to set abrightness value for a user according to each ambient light; a memory module is used to store each digital brightness value and each set brightness value; and a processing module is used to calculatea plurality of screen brightness values according to each digital brightness value and each set brightness value and store the screen brightness values in the memory module. A backlight control module is used to search one screen brightness value in the memory module automatically according to the current ambient light sources sensed by the photosensitive module to adjust the brightness of the screen backlight.

Description

technical field [0001] The present invention relates to a screen brightness automatic adjustment system and method thereof, in particular to a screen brightness automatic adjustment system and method capable of automatically adjusting the brightness of a screen backlight by sensing a light source in the surrounding environment. Background technique [0002] At present, most of the handheld mobile communication devices use a fixed current to control the brightness of the backlight module and the indicator light, so as to allow the user to watch the content on the screen and operate the mobile phone. However, when there is a strong light source outside, the user often has to manually adjust the driving current to make the content of the display screen clearer. Similarly, when the external light source is low, if the display screen is controlled with the original operating current, the user will often feel that the screen light source is too dazzling and uncomfortable. If the ...
