Embodiment Construction

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0035] An electronic device, such as a mobile phone or a tablet computer, generally detects a distance between the electronic device and a user by installing an infrared sensor. Taking a mobile phone as an example, an infrared sensor is provided on the upper area of ​​the mobile phone. When the user makes a voice call or related operations, the mobile phone is close to the head, and the infrared sensor feeds back the distance information to the processor, and the processor executes corresponding instructions, such as turning off the lights ...

Abstract

The invention discloses a display screen, an electronic device and a manufacturing method of the display screen. The display screen comprises an organic light-emitting layer, a TFT circuit layer, a polarizer and an infrared sensor, wherein the TFT circuit layer is arranged below the organic light-emitting layer, and the TFT circuit layer is used for driving the organic light-emitting layer to emitlight to be displayed; the polarizer is arranged above the organic light-emitting layer; the infrared sensor is arranged above the polarizer, and is used for transmitting and / or receiving infrared light. The invention also discloses an electronic device and a manufacturing method of the display screen. According to the display screen, the electronic device and the manufacturing method of the display screen, the infrared sensor can be arranged on the polarizer under the condition of a full screen, so that the phenomenon of screen flicker caused by the fact that the infrared sensor is arrangedbelow the TFT circuit layer can be avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a display screen, an electronic device and a manufacturing method of the display screen. Background technique [0002] Generally, an electronic device such as a mobile phone includes components such as a display screen and an infrared sensor, and the infrared sensor can be used to detect the distance between an object outside the display screen and the display screen. With the development of mobile phone technology and the needs of users, full-screen mobile phones have become the development trend of mobile phones, but the current arrangement of infrared sensors makes the screen-to-body ratio of mobile phones smaller. However, when the infrared sensor is arranged under the display screen, it is easy to cause flickering of the screen. Contents of the invention [0003] In order to solve the above technical problems, embodiments of the present invention provide a display scr...
