Abstract

The invention provides a liquid crystal display device with a fingerprint recognition function. The liquid crystal display device comprises a liquid crystal display screen body and a backlight assembly, wherein the backlight assembly comprises a fingerprint recognition backlight module, and the liquid crystal display screen body is arranged on the side of a light-emitting direction of the fingerprint recognition backlight module. Because of the thin and light characteristics of the liquid crystal display screen body, the liquid crystal display screen body can easily integrate an under-screen optical fingerprint scheme. By means of a self-illumination characteristic of an OLED, and cooperating with a liquid crystal display screen, an OLED screen body replaces or partially replaces a previous LED and light guide backlight module, thereby overcoming the shortcoming that optical fingerprint recognition cannot be performed caused by a light guide plate problem, and an optical fingerprint recognition process is completed through the detailed design of an OLED illumination screen body.
