Embodiment Construction

[0039] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] In this embodiment, a current processing chip, a filter chip and a phototransistor are embedded in the mobile phone, so that the mobile phone has the function of sensing light, and automatically adjusts the brightness of the backlight according to the magnitude of the sensing light. in,

[0041] Phototransistors are used to sense light from the external environment and generate currents of different sizes according to the sensed light. Crystal silicon wafers used to produce integrated circuits, such as photoresistors, can be used; single crystal silicon wafers, such as photodiodes, can also be used. Jia is an IC-based monolithic photodiode, which is based on a single crystal silicon wafer and has the characteristics of high precision, small size and low price.

[0042] figure 2 Shown is the functional module diagram related to the sen...

Abstract

The invention relates to a mobile phone with induction light function, comprising a photoelectric transistor, a current processing chip and a microprocessor. The photoelectric transistor is used for inducing light rays in the external environment and generating current varying in size according to the strength of light rays of the induction light; the current processing chip converts current generated by the photoelectric transistor into a voltage value; and the microprocessor is used for comparing the voltage value transmitted from the current processing chip with the configured voltage range, finding the voltage range of the voltage value, generating luminance control signals corresponding to the voltage range and controlling the luminance of backlight. Correspondingly, the invention also provides a method for realizing the induction light function of the mobile phone. In the invention, the brightness of the screen of the mobile phone and the backlight of a keyboard can be automatically regulated according to the brightness level of light rays in the external environment when the brightness of light rays in the external environment is in different states.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a mobile phone with a light-sensing function and a realization method thereof. Background technique [0002] With the popularity of mobile phone applications, more and more people use mobile phones in my country, and more and more elderly people, primary and middle school students, and some people with low vision also need to use mobile phones. And their group has much higher requirements for light than young and middle-aged people. Elderly people with poor eyesight need to adjust the light of the mobile phone screen and keyboard. Primary and middle school students are in a state of learning all day long and need to adjust the light of the mobile phone screen and keyboard to protect their eyesight. The purpose of viewing and reading. [0003] But there is no mobile phone at present that can realize the mobile phone that automatically adjusts the backlight according to the external environment,...
