Abstract

The present invention relates to the field of handheld terminals, and provides a method and a structure for increasing a receiving angle of an optical sensor, and a handheld terminal, which increase an angle for an optical sensor to receive external light, and realize simple assembly and low cost. The structure for increasing a receiving angle of an optical sensor includes touchscreen glass, an optical sensor, and a main board, where an ambient light hole is provided on the touchscreen glass; the optical sensor is disposed between the touchscreen glass and the main board; and a light uniformizing film is disposed between the touchscreen glass and the optical sensor, is in contact with the touchscreen glass, and completely covers the ambient light hole. The handheld terminal includes the foregoing structure for increasing a receiving angle of an optical sensor.

Description

technical field [0001] The invention relates to the field of handheld terminals, in particular to a method and structure for increasing the receiving angle of a light sensor and a handheld terminal. Background technique [0002] Currently, light sensors are widely used in touch screen mobile phones. The light sensor receives the external ambient light, and controls the brightness of the display screen of the mobile phone by sensing the intensity of the external ambient light. When the user uses the mobile phone, the light from the external environment is incident from different directions. Since the angle of light received by the light sensor is limited to a certain extent, and the glass structure of the touch screen will also affect the angle of light received by the light sensor, the light receiving angle of the mobile phone Smaller, thus affecting the brightness of the display screen of the mobile phone under different ambient light. [0003] In order to increase the re...
