Embodiment Construction

[0020] like figure 1 As shown, the working circuit diagram of the light sensor mainly includes power chip 1 (PMIC), light sensor chip 2 (Light SensorChip), baseband chip 3 (BB Chip), backlight chip 4 (Back Light Chip), backlight 7, audio control module 5 (AudioControl Module) and speaker 6.

[0021] Among them, the power supply chip 1 provides power drive for the whole circuit, and the light sensor chip 2 is responsible for obtaining light intensity from the outside and performing sampling processing. It needs a fixed ADC channel provided by the baseband chip 3 to control its data acquisition. The baseband chip 3 is the whole In the center of the centralized processing and adjustment of the circuit, a pull-down resistor R is set between the baseband chip 3 and the light-sensing chip 2, which is mainly used to stabilize the data output of the light-sensing chip 2 and avoid jumping up and down at the critical value of the level. The backlight chip 4 Adjust the backlight of the ...

Abstract

The invention provides a light sense energy saving system of a mobile and a method thereof and a method for achieving light sense energy saving. The light sense energy saving system of the mobile comprises a backlight chip, an audio control module and a light sense chip, wherein, the light sense chip obtains light intensity from outside and carries out sampling processing, a baseband chip provides a fixed ADC channel for the light sense chip to control data acquisition carried out by the light sense chip, the backlight chip adjusts the back light of the phone keypad and the LCD screen, and the audio control module adjusts the volume of the phone. The invention has the beneficial effects that the energy consumption of the phone is lowered effectively, the service life of the phone battery is prolonged and the brightness of the backlight and the volume of the phone can be conveniently adjusted by sensing optical lines outside and judging external environmental changes.

Description

technical field [0001] The invention relates to a light-sensing energy-saving system and a light-sensing energy-saving implementation method in a mobile phone, in particular to a hardware structure and a software implementation method for saving energy by controlling the backlight of the mobile phone and the volume of the mobile phone by sensing the intensity of external light. Background technique [0002] With the development trend of domestic mobile phones and the increase of functions, higher requirements are put forward for energy consumption and battery life. However, while the size of mobile phones must be small, we can only work on power saving. The popularization of multimedia mobile phones, the expansion of audio-visual entertainment applications of mobile products such as support for MP3, MP4, mobile TV and even video calls and richer entertainment functions supported by 3G mobile phones in the future, and energy-saving solutions will have an important impact on it...
