Abstract

The invention discloses a calibration method and system for the optical sensor of a mobile phone. The system comprises a power supply, a computer with a test program, a mobile phone with an optical sensor and a test fixture for fixing the mobile phone, wherein the test fixture is provided with a shielding cover for containing the mobile phone and forming a sealed space; and a surface light source device is arranged in the shielding cover. Because the system is used on a mobile phone production line, an environment with fixed light intensity is provided, and the optical sensor of each mobile phone is calibrated on line; then, a calibrated compensation value is written in each mobile phone; thus, consistency between the mobile phones can be guaranteed to the maximum degree; difference between mobile phone sensors can be solved; the calibration precision of the optical sensor is improved; meanwhile, test efficiency is improved; and production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a mobile phone optical sensor calibration method and system. Background technique [0002] With the development of mobile communications and the continuous improvement of people's living standards, the use of mobile phones has become more and more popular, and mobile phones have become an indispensable communication tool in people's lives. Short-range proximity sensors in existing mobile phones are becoming more and more important to manage various functions of the mobile phone and make these feature-rich mobile devices more flexible and user-friendly, while reducing power consumption, Extend battery life. [0003] In order to meet the needs of smart phones, people have developed a new generation of optical sensors, which can automatically adjust the brightness of the mobile phone LCD by collecting external light sources. Usually, mobile phone manufacturers will obtai...
