Problems solved by technology

In order to meet the monitoring requirements of DMS, it is necessary to install an optical element on the liquid crystal display. The solution of hiding the camera on the back of the LCD panel is often adopted, but while this solution solves the problem of exposure of the camera, it also makes it necessary for the camera to perform the lighting function, and the external ambient light must at least pass through the LCD panel before it can be emitted smoothly. Into the camera, it greatly increases the difficulty of the camera to adopt the external environment light, which directly leads to the problem of insufficient lighting of the camera and poor DMS imaging effect. This problem needs to be solved urgently

Embodiment 1

[0052] image 3 It shows a schematic structural diagram of the first substrate in the display panel provided by Embodiment 1 of the present application; Figure 4 It shows that the black matrix ring provided by Embodiment 1 of the present application is in figure 2 The schematic diagram of the location of the A area; Figure 5 It shows that the first notch and the second notch provided by Embodiment 1 of the present application are in figure 2 The schematic diagram of the location of the A area;

[0053] Image 6 A schematic structural diagram of the second substrate in the display panel provided by Embodiment 1 of the present application is shown. Combine below Figure 3-Figure 6 , the specific film layer structures of the first substrate 100 and the second substrate 200 in the display panel 10 will be described in detail.

[0054] In this embodiment, the alignment layer includes a first alignment layer 160 disposed on the first substrate 100 and a second alignment la...

Embodiment 2

[0073] Figure 7 It shows a schematic structural diagram of the second substrate in the display panel provided by Embodiment 2 of the present application, as shown in Figure 7 As shown, Embodiment 2 of the present application provides a display panel 10 , and the structure of the display panel 10 is similar to that of the display panel 10 in Embodiment 1 of the present application. The same parts will not be repeated in this embodiment.

[0074] The difference is that the interlayer dielectric layer 220 in the display panel 10 provided in the second embodiment of the present application is located in the display area 11 and the transition area 13, that is, the interlayer dielectric layer 220 is not provided in the light transmission area 12 , thereby simplifying the film layer structure of the light-transmitting region 12 , reducing the number of film layers, and further improving the infrared light transmittance of the display panel 10 in the light-transmitting region 12 . ...

Abstract

The invention provides a display panel and a display device. The display panel comprises a first substrate, a second substrate and a liquid crystal layer, the first substrate and the second substrate are oppositely arranged, the liquid crystal layer is located between the first substrate and the second substrate, and the sides, close to the liquid crystal layer, of the first substrate and the second substrate are each provided with an alignment layer. The display panel comprises a display area and a light-transmitting area, and at least one alignment layer is provided with a notch in the light-transmitting area. According to the display panel, the notches are formed in the at least one alignment layer of the display panel, so that when external light rays enter an optical element through the display panel, the filtering effect of the alignment layers on the light rays is greatly weakened, light loss is reduced, the light transmittance of the area, corresponding to the optical element, of the display panel is improved, the difficulty that an optical element adopts external environment light is reduced, and the lighting amount of the optical element is effectively increased.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Liquid Crystal Display (LCD) is widely used in vehicles, mobile phones, TVs, personal digital assistants, digital Various consumer electronic products such as cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] In the on-board display, the Driver Monitor System (DMS) can monitor the driver's fatigue and improve driving safety performance. At the same time, with the gradual maturity of automatic driving, Internet of Vehicles and related technologies, DMS gradually More functions have evolved and iterated, and are gradually recognized by users. In order to meet the monitoring requirements of DMS, it is necessary to install an optical element on the liquid crystal display. The solution of hiding the camera on the back of the LCD panel is often adop...
