Under-screen monitoring display device

Abstract

The invention provides an under-screen monitoring display device. The under-screen monitoring display device comprises a liquid crystal panel and a backlight module located on the back of the liquid crystal panel. The display panel comprises at least one camera shooting area used for receiving external light, and the backlight module is provided with a backlight hole corresponding to the camera shooting area; a monitoring system is arranged in the backlight hole, the monitoring system comprises a DMS module with an infrared sensor, and an infrared ray penetrating layer is arranged on the daylighting path of the DMS module; the side, away from the backlight module, of the liquid crystal panel is further provided with a protective cover plate, and the color of the infrared transmitting layer is consistent with the surface color of the protective cover plate, so that the reflectivity of a camera shooting area is properly improved, the reflectivity of the camera shooting area is consistent with that of a normal display area, and a better integrated black effect during shutdown is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an under-screen monitoring and display device. Background technique [0002] DMS, the full name of Driver Monitor System, is the driver status monitoring system. The early DMS was mainly driver fatigue monitoring. With the gradual maturity of automatic driving, Internet of Vehicles and related technologies, more functions have been gradually evolved and iterated. The DMS monitoring system mainly includes basic functions such as smoking monitoring, phone call monitoring, distracted driving monitoring, seat belt not wearing monitoring, drinking water monitoring, yawning monitoring, eye closure monitoring, and abnormal state monitoring. [0003] Use the images acquired by the DMS module to detect the driver's driving behavior and physiological state through visual tracking, target detection, action recognition and other technologies. In the event of a situation, the system will g...

Problems solved by technology

[0005] Based on the existing technical problems, this application provides an under-screen monitoring and display device, which can solve the problem that the DMS module used in the existing under-screen liquid crystal display device has an infrared sensing module, and the infrared sensing module collects optical signals in the 650nm-940nm band , RGB photoresist has a high transmittance in the IR band, and can image images through the light-shielding layer on the surface of the glass cover. Since the existing imaging area is a through hole, the corresponding imaging area on the color filter side of the LCD panel is generally designed not to use BM / RGB / PS photoresist, so the color difference between the camera area and the normal display area is relatively large, the DMS module cannot be hidden under the display panel, and there is a technical problem that the overall black effect is not good when the display device is turned off
