Embodiment Construction

[0034] like figure 1 As shown, a method to prevent the film from affecting the normal operation of the proximity sensor includes the following steps:

[0035] Detect whether there is a film on the current touch screen;

[0036] Detect the infrared intensity value of the proximity sensor when there is no object blocking, and judge whether it is within the normal range;

[0037] If it is detected that there is a film on the current touch screen, and the infrared intensity value of the proximity sensor exceeds the normal range when there is no object blocking, it is determined that the film affects the normal operation of the proximity sensor and the user is prompted.

[0038] The method for preventing the film from affecting the normal operation of the proximity sensor described in this embodiment is to determine whether the film affects the normal operation of the proximity sensor by monitoring whether there is a film on the touch screen and whether the infrared intensity valu...

Abstract

The invention discloses a method for preventing a sticking film from affecting normal working of a proximity transducer. The method comprises the following steps: detecting whether a current touch screen is provided with the sticking film or not, detecting an infrared strength value of the proximity transducer when the proximity transducer is not shielded by objects, judging whether the infrared strength value is in the normal range or not, if it is detected that the current touch screen is provided with the sticking film and the infrared strength value of the proximity transducer exceeds the normal range when the proximity transducer is not shielded by the objects, judging that the sticking film affects the normal working of the proximity transducer, and reminding a user. According to the method for preventing the sticking film from affecting the normal working of the proximity transducer, whether the sticking film affects the normal working of the proximity transducer or not is judged by monitoring whether the touch screen is provided with the sticking film or not and monitoring whether the infrared strength value exceeds the normal range or not when the proximity transducer is not shielded by the objects, the user is timely reminded, and the blank screen phenomenon caused by the sticking film on the mobile phone screen is prevented from appearing. The invention further provides a device for preventing the sticking film from affecting the normal working of the proximity transducer.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and a device for preventing a film from affecting the normal operation of a proximity sensor. Background technique [0002] Proximity sensors are widely used in smart phones. The proximity sensor has a built-in infrared generating tube and an infrared receiving tube. When making a call, when the face is close to the proximity sensor, the receiving tube receives a relatively strong infrared reflection signal. Once the intensity exceeds a certain Set the value, such as 900, the proximity sensor generates an interrupt, and the screen goes out, which is used to reduce power consumption and reduce touch screen misuse; when the face is far away from the proximity sensor, once the infrared reflection intensity is less than a certain set value, such as 300, the screen will turn off. Bright. [0003] The proximity sensor on a smart phone is generally set above or below the touch scree...
