Problems solved by technology

[0006] And the acoustic impedance difference between gas and solid / liquid is greater than 20x, so if there is any lift in the propagation path from the ultrasonic fingerprint surface to the finger surface, it will cause the ultrasonic fingerprint to not work
[0007] Therefore, that is to say, the existing G-OLED cannot adopt the ultrasonic fingerprint solution under the screen.

Abstract

The invention provides a display screen, an electronic device and a production method of the display screen. The display screen comprises an upper glass substrate, a lower glass substrate, supporting parts, a thin film transistor and filling layers; the supporting parts are arranged between the upper glass substrate and the lower glass substrate, and the supporting parts are used for supporting and fixing the upper glass substrate and the lower glass substrate; the thin film transistor is arranged on one surface, towards the upper glass substrate, of the lower glass substrate; the filling layers are formed between the upper glass substrate and the lower glass substrate and allow light rays or ultrasonic waves to penetrate, and the filling layers are in a flowing state or solid state. The display screen can be applied to a scheme that an ultrasonic wave fingerprint is used on the screen, so that the screen rate of the electronic device is larger, and the user requirements are met.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a display screen, electronic equipment and a preparation method of the display screen. Background technique [0002] The traditional liquid crystal panel OLED (hereinafter referred to as G-OLED) usually consists of two layers of glass substrates with a thickness of 0.2mm-0.3mm, a thin film transistor in the middle, and a light-emitting material. Usually there is a certain gap between the two glass substrates, so there is a certain amount of gas. [0003] Conventional G-OLED is no problem in the process of use, but now as users have more and more requirements for screen-to-body ratio, the design of the whole machine needs to place the fingerprint detector under the screen, that is, on the LCD panel Down. One of the commonly used fingerprint schemes is ultrasonic fingerprinting. [0004] The principle of ultrasonic fingerprint collection is to use the sound wave with a freq...
