Abstract

The invention provides a fingerprint identification display device, a preparation method thereof and a fingerprint identification display device. The fingerprint identification display device comprises a photoelectric sensor array layer, a collimator and a display device which are stacked in sequence, wherein the collimator comprises at least two transparent polyimide layers and at least one shading metal layer; The fingerprint identification display device is simple in structure, small in number of film layers, simple in preparation process and capable of reducing the thickness of a product and solving the problem that in the prior art, a collimator is directly prepared above a photoelectric sensor array layer through an organic photoelectric material, and process difficulty is large.

Description

technical field [0001] The invention relates to the technical field of display products, in particular to a fingerprint identification display device, a preparation method thereof, and a fingerprint identification display device. Background technique [0002] Flat display devices such as liquid crystal display (Liquid Crystal Display, LCD), organic light emitting diode display (Organic Light Emitting Display, OLED), and display devices using light emitting diode (Light Emitting Diode, LED) devices have high image quality, save It is widely used in various consumer electronic products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, desktop computers, etc., and has become the mainstream of display devices. [0003] In current fingerprint identification display devices, in order to avoid crosstalk between different light rays, a collimator needs to be prepared above the photosensor array layer. However, in the existing tech...
