Problems solved by technology

However, there is a lot of infrared interference in the normal environment, especially in outdoor sunlight, where the intensity of infrared rays is very high. Strong infrared rays will interfere with the intensity of infrared light sensed by the proximity sensor, affecting the infrared sensor's approach and distance judgment effect, causing the mobile phone to approach and move away. Misjudgment caused inconvenience to users

Abstract

The invention provides a method and a system for controlling a working state of a touch screen of a mobile terminal. The mobile terminal comprises an infrared proximity sensor and an ambient light sensor. The infrared proximity sensor is used for sensing infrared light intensity values, and the ambient light sensor is used for sensing ambient light intensity values. The method includes steps of detecting whether communication operation is carried out or not; acquiring an infrared light intensity value sensed by the infrared proximity sensor if the communication operation is carried out; detecting to judge whether the infrared light intensity value is larger than a proximity threshold value or not; acquiring an ambient light intensity value sensed by the ambient light intensity sensor if the infrared light intensity value is larger than the proximity threshold value; detecting to judge whether the ambient light intensity value is smaller than a preset intensity value or not; and locking the touch screen if the ambient light intensity value is smaller than the preset intensity value. The method and the system have the advantage that the threshold value of the infrared proximity sensor is set, so that influence of ambient light on the accuracy of a detection function of the infrared proximity sensor can be prevented.

Description

technical field [0001] The invention belongs to the field of infrared proximity sensors, and in particular relates to a method and a system for controlling the working state of a touch screen by a mobile terminal. Background technique [0002] Capacitive touch screen smartphones use infrared proximity sensors to sense in order to prevent misoperations caused by face contact with the touch screen during a call. The infrared proximity sensor is composed of an infrared LED light and an infrared photosensitive sensor. The infrared LED emits infrared light. When an object approaches, a part of the infrared light is reflected by the obstacle to the infrared light sensor. The infrared light sensor senses the infrared light intensity value. When When the infrared light intensity value is greater than a proximity threshold, the mobile phone thinks that there is an object approaching at this time, and the screen is turned off during a call, and the touch screen is prohibited from resp...
