Problems solved by technology
However, although the traditional vehicle-mounted under-display camera has a good shooting effect in the daytime, the imaging quality is poor due to the limitation of the environment in a dark environment. As a result, the traditional vehicle-mounted under-display camera cannot meet the needs of the vehicle driver monitoring system.
[0003] Therefore, it is necessary to propose a technical solution to solve the problem of poor imaging quality of traditional vehicle under-screen cameras in dark environments

Abstract
The invention provides a vehicle-mounted display device. The device comprises a display panel and aninfrared sensing assembly, wherein the display panel is provided with a non-display light-transmitting region and a display region located at the periphery of the non-display light-transmitting region; the infrared sensing assembly is located on the back side of the light-emitting face of the display panel and corresponds to the non-display light-transmitting region, and the infrared sensing assembly is used for receiving infrared light; and the transmittance of the non-display light-transmitting region of the display panel to the infrared light is greater than the transmittance of the display region of the display panel to the infrared light.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a vehicle-mounted display device. Background technique [0002] At present, based on the requirement that the in-vehicle driver monitor system (Driver Monitor System, DMS) needs to use a camera to monitor continuous driving and driver status, the off-screen camera technology is applied to the in-vehicle driver monitor system. However, although the traditional vehicle-mounted under-display camera has a good shooting effect in the daytime, the image quality is poor due to the limitation of the environment in a dark environment. As a result, the traditional vehicle-mounted under-display camera cannot meet the needs of the vehicle driver monitoring system. [0003] Therefore, it is necessary to propose a technical solution to solve the problem of poor imaging quality of traditional vehicle-mounted under-display cameras in a dark environment.
