Front camera module and mobile terminal

Abstract

Embodiments of the invention relate to the technical field of electronic products, and disclose a front camera module and a mobile terminal. In the embodiments of the invention, the front camera module comprises a bracket with a light-passing hole at the top, a lens mounted in the light-passing hole, a filter, a front camera chip, and an ITO film. The ITO film is spattered on the surface of the filter and connected to a flexible circuit board extending from the front camera chip. The filter is fixed at the bottom of the bracket. The front camera chip is used for controlling the ITO film to detect an external capacitance change value of the mobile terminal, and sending an off signal to a processor to turn off the screen when the change value of the external capacitance is greater than a preset threshold value. According to the embodiments of the invention, the distance sensing function is realized while the shooting function is ensured, the screen space and the cost are saved, the stability of the screen ratio and the distance detection is improved, the phenomenon that the screen may not be off during a call is avoided, and user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic products, and in particular to a proactive module and a mobile terminal. Background technique [0002] Electronic devices such as mobile phones are widely used in people's daily life, and their integrated functions provide great convenience for people's lives. Among them, the distance sensing function of the mobile phone is applied under the handset mode of the mobile phone, for example, in the handset mode When making a call, the phone screen will be off to prevent accidental touches and save power. In existing mobile phones, the following three schemes are generally adopted to realize the distance sensing function: the first scheme realizes the distance sensing function through a distance sensor, and the distance sensor is located in an opening of the screen of the mobile phone. The second solution realizes the distance sensing function through an ultrasonic sensor, and...

AI Technical Summary

Problems solved by technology

[0003] However, the inventors found that there are at least the following problems in the prior art: In the first solution, the distance sensor will occupy the screen space of the mobile phone, which reduces the screen-to-body ratio and increases the difficulty for realizing a full screen

In the second solution, the cost of ultrasound is too high, and it takes up the internal space of the mobile phone

In the third solution, the distance between the earpiece located in the non-display area and the touch sensor located in the display area is relatively long. Sometimes the ear is close to the earpiece but there is still a distance between the face and the touch sensor, and the detection distance of the touch sensor is not stable. As a result, the screen may not be turned off during a call, which reduces the user experience
