Abstract

The invention provides a calibration method, a testing method and a manufacturing method for an optical sensor of a mobile terminal. The calibration method for the optical sensor of the mobile terminal includes the steps of concurrently downloading a calibration plug-in when system software is downloaded through the mobile terminal, then installing the system software on the mobile terminal, providing a testing light source which is provided with a preset light intensity value and correspondingly irradiates the optical sensor, running the calibration plug-in to detect an induction signal generated by the fact that the optical sensor is irradiated by the testing light source, obtaining an induction light intensity value of the induction signal, calculating a calibration parameter according to the induction light intensity value and the preset light intensity value, and accordingly writing the calibration parameter into the mobile terminal. The calibration method is applied to the testing or manufacturing process of each mobile terminal, automatic detection is carried out without peripheral equipment, cost is low, efficiency is high, and as the zero-drift optical sensor and the special light source are adopted, the accuracy is high.

Description

technical field [0001] The present invention relates to a mobile terminal, in particular to a calibration method, a testing method and a manufacturing method for an optical sensor of a mobile terminal. Background technique [0002] Mobile terminals such as mobile phones and tablets are widely used due to their powerful functions and excellent portability. Consumers use it in various fields, in various places and at various times. Then it is necessary for the mobile terminal to automatically adjust the screen brightness in different occasions, so that the screen can be seen clearly under strong light, and it is not dazzling when it is dark, and it is energy-saving and environmentally friendly. [0003] Therefore, most of the current mobile terminals are equipped with light sensors to sense the light brightness of the user's current environment, and automatically adjust the screen brightness based on this. So how to make the tens of millions of mobile terminal products actua...
