Features: 1Integrated with ambient light,approaching sensor and infrared light LED. 2Small size,suitable for being used in fine crafts. 3The function is upgraded with strong adaptability. 4Mainly used in two aspects, on the one hand to detect the current ambient light brightness (ALS) and use software adjustment method to automatically adjust the backlight brightness according to the current ambient light brightness to adapt to the ambient brightness The function of protecting vision can also achieve the effect of power saving another function is called proximity sensing function (PROX), which uses the reflection of infrared light emitted by internal LED and the reception of built-in PD of sensor to determine whether the mobile phone is close to the face during the call. In order to determine the backlight status and the touch screen button status ON/OFF. 5An infrared emitter is integrated inside, eliminating the need for external LED support. Mininal design and installation are more space-free, and structural requirements are simpler. The three-in-one sensor device has been internally partitioned with stainless steel.
