Problems solved by technology

However, for the liquid crystal display module, the light emitted by the general distance sensor has a low ability to penetrate the liquid crystal display module, so the distance sensor cannot receive the light reflected by the object outside the electronic device, so it cannot detect whether the object blocks the liquid crystal display module. display module

Abstract

The application discloses an electronic device comprising a backlight module, a liquid crystal display screen, and a distance sensor. The backlight module includes a diaphragm assembly. The liquid crystal display screen covers that backlight diaphragm assembly. The distance sensor is used for emitting infrared light to the outside of the electronic device through the diaphragm assemblyand the liquid crystal display screen, and for receiving infrared light reflected from an object outside the electronic device through the liquid crystal display screen and the diaphragm assembly, and the wavelength of the infrared light is greater than or equal to 1300 nm. In an electronic device according to an embodiment of the present application, since the wavelength of infrared light emitted by the distance sensor is greater than or equal to 1300 nm, infrared light can penetrate through the membrane module, and the distance sensor can receive infrared light reflected by the object to detect whetherthe object blocks the liquid crystal display module.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to an electronic device. Background technique [0002] Electronic devices such as mobile phones with a large screen-to-body ratio are increasingly favored by users. In order to increase the screen-to-body ratio of the electronic device and prevent interference between functional devices such as distance sensors and the electronic device, the functional devices can be installed under the display screen assembly. However, for the liquid crystal display module, the light emitted by the general distance sensor has a low ability to penetrate the liquid crystal display module, so the distance sensor cannot receive the light reflected by the object outside the electronic device, so it cannot detect whether the object blocks the liquid crystal display module. Display mods. Contents of the invention [0003] In view of this, the present application provides an electronic d...
