Therefore, the infrared light source can be arranged on one side of the electronic element far away from the display panel, and meanwhile, in the electronic element arrangement area, the projection of the infrared light source and the projection of the electronic element are not overlapped, so that the light emitted by the infrared light source cannot be shielded by the electronic element.
In one embodiment, the electronic component includes an infrared camera.
In one embodiment, the infrared light source is disposed in the electronic component disposing region, and the infrared light source is disposed in the backlight module, so that the thickness of the display device can be reduced by disposing the infrared light source in the backlight module.
Specifically, backlight unit can normally set up the display light source in the display area, and sets up infrared light source in the electronic component setting area to make the light reinforcing in electronic component setting area, improve electronic component's daylighting effect.
Specifically, taking the display device as an on-vehicle instrument panel as an example, as shown in fig. 6, the display device 2 includes an instrument data display area 211 and an infrared camera display area 212, and the infrared camera display area 212 is provided with a visible light blocking layer, so that when the display device 2 displays, full black display can be realized, and the infrared camera and the instrument panel do not need to be separately arranged, thereby saving space.
According to the above embodiments:
the embodiment of the application provides a display panel and a display device, the display panel comprises a display area and an electronic element setting area, the electronic element setting area is used for setting an electronic element, the electronic element setting area is used for transmitting infrared rays, a visible light blocking layer is formed in the electronic element setting area, and the visible light blocking layer is used for blocking visible light. This application sets up the district through setting up electronic component in display panel, sets up electronic component in electronic component and sets up the district, need not to set up electronic component alone, and through setting up visible light barrier layer in electronic component setting district, blocks visible light, then can realize that electronic component sets up the complete black demonstration in district, when avoiding display panel to show black, unable complete black demonstration influences the display effect.
In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
The display panel and the display device provided by the embodiments of the present application are described in detail above, and the principles and embodiments of the present application are explained herein by applying specific examples, and the description of the embodiments above is only used to help understand the technical solutions and the core ideas of the present application; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present disclosure as defined by the appended claims.
