Abstract

A method for calibrating an ambient light source sensing element, which is used to correct the sensitivity of an ambient light source sensing element disposed on a circuit board through an adjustable resistor, the adjustable resistor and the ambient light source sensing element are disposed on the The front side of the circuit board, and the adjustable resistor and a switch are connected in series between the correction pin of the ambient light sensing element and the ground. The external resistor is electrically connected between the two solder points on the back of the circuit board through the thimble, and the external resistor replaces the adjustable resistor to measure the sensitivity of the ambient light sensing element through the control unit, and calculate the The resistance value of the adjustable resistor. The method for calibrating the ambient light sensing element of the present invention is simple to operate, and can improve the calibrating efficiency of the ambient light sensing element and save costs.

Description

technical field [0001] The invention relates to a parameter correction method of an ambient light sensor (Ambient Light Sensor, ALS). Background technique [0002] With the development of sensing technology and network communication technology, intelligent controllers that integrate sensing capabilities, computing capabilities, and communication capabilities are increasingly used. The intelligent controller can sense the surrounding environment, process the sensed data, and communicate with other devices through the network, so as to realize the real-time grasp of the environment. For example, the ambient light sensor (Ambient Light Sensor, ALS) can detect the amount of light in the surrounding environment at any time, and transmit the sensed signal to the controller to automatically adjust the lighting status of the backlight module, effectively reducing the possible The power consumption of portable electronic products (such as mobile phones, notebooks, etc.). [0003] s...
