Electronic device with non-contact intelligent key and control method thereof

Abstract

The invention relates to an electronic device with non-contact intelligent key and a control method thereof. The electronic device with the non-contact intelligent key comprises a key used for executing a function of the electronic device after being triggered, wherein the key comprises a quantum well diode, the quantum well diode is used for detecting whether the light intensity of the external environment is changed or not in a non-lightened state, and if yes, light current is generated; an analog-to-digital signal processing module which connected with the quantum well diode and used for carrying out analog-to-digital conversion and decoding judgment on the photocurrent; and a single chip microcomputer connected with the analog-to-digital signal processing module and is used for confirming that the key triggered and executing the function when the decoding judgment determines that the light current exceeds a threshold range. According to the invention, direct touch contact betweena user and the key is avoided, and the problem of bacterial and viral cross infection easily caused by contact type triggering of the key in public places is effectively avoided.

Description

technical field [0001] The invention relates to the fields of illumination, display and optical communication, in particular to an electronic device with a non-contact intelligent key and a control method thereof. Background technique [0002] GaN material has a good photoelectric effect, it has a higher band gap, a greater electron saturation drift velocity, a stronger near-breakdown electric field, and higher thermal conductivity and thermal stability. Ideal material for high temperature, high pressure and high power devices. Studies have shown that GaN materials have the phenomenon of coexistence of light emission and detection, which provides a new direction for the development of visible light communication, photonic interconnection and optical microelectronic devices. [0003] In order to facilitate people's life, various buttons are often arranged in public places, such as elevator buttons, toilet buttons in public restrooms, etc. However, these buttons are usually c...
