Problems solved by technology

[0004] In addition, another demand in the current market is the miniaturization of the opening of the proximity sensing module, and the integration of the opening of the transmitter and the opening of the sensor. Another challenge brought about by such a demand is to reduce the size of the transmitter and the sensor. The distance between the sensor and the opening aperture of the sensor is maintained at the same time, but the crosstalk effect in the proximity sensor will increase, resulting in a decrease in the sensing ability of the proximity sensor for short distances

Abstract

The invention discloses a mobile device and a proximity sensing module thereof. The proximity sensing module comprises a circuit substrate, a transmitter encapsulation unit, a receiver encapsulation unit, a plastic housing and a lens. The transmitter encapsulation unit and the receiver encapsulation unit are arranged on the circuit board. The plastic housing covers the transmitter encapsulation unit and the receiver encapsulation unit. The plastic housing has a first opening corresponding to the transmitter encapsulation unit and a second opening corresponding to the receiver encapsulation unit, and the first opening and the second opening have a first geometric centerline and a second geometric centerline, respectively. The lens is disposed on the transmitter encapsulation unit, and lightgenerated by the transmitter of the transmitter encapsulation unit passes through the lens and exits from the first opening. The height of the transmitter package is lower than the height of the receiver package, thereby reducing the crosstalk effect of the proximity sensing module.

Description

technical field [0001] The present invention relates to a sensing module, in particular to a proximity sensing module and a mobile device using the proximity sensing module. Background technique [0002] With the development of mobile device technology, mobile devices with touch screens have become more and more popular. Therefore, the demand for setting proximity sensors in the touch screens of mobile devices is also increasing, so that when users hold mobile devices to talk, The proximity sensor inside the touch screen can sense the user's face, ear or hair and temporarily turn off the screen function. On the one hand, it achieves the technical effect of power saving, and on the other hand, it also prevents the user's face and ear from accidentally touching the screen during a call. [0003] In the existing proximity sensor, the emitter and the sensor are separately arranged in the touch screen, and a far-infrared optical isolator integrated with the mobile phone is arrang...
