Problems solved by technology

[0004] However, the accuracy of the current ink coating technology is low, resulting in poor shading effect of the coated ink, which not only reduces the display effect of the display screen, but also increases the frame width of the display screen, which is not conducive to the manufacture of a narrow frame display screen

Embodiment 2

[0081] Figure 5 It is a schematic structural diagram of the second light-shielding layer of the display panel provided by Embodiment 2 of the present invention. refer to Figure 5 As shown, on the basis of the first embodiment above, the second embodiment of the present invention provides a display panel. Compared with the first embodiment, the difference between the second embodiment and the first embodiment is that the position of the light-shielding layer 31 is different. .

[0082] Specifically, the light-shielding layer 31 includes a second light-shielding layer 312 disposed between the insulating barrier layer 60 and the encapsulation layer 50 , and the second light-shielding layer 312 is in contact with the second electrode layer 23 through the insulating barrier layer 60 .

[0083] It should be noted that the second light-shielding layer 312 can be a single-layer light-shielding layer or a composite light-shielding layer. The material for forming the second light-s...

Embodiment 3

[0087] Figure 6 A schematic structural diagram of the first light-shielding layer and the second light-shielding layer of the display panel provided by Embodiment 3 of the present invention. refer to Figure 6 As shown, on the basis of Embodiment 1 or Embodiment 2 above, Embodiment 3 of the present invention provides a display panel. Compared with Embodiment 1 or Embodiment 2, Embodiment 3 differs in that: the light-shielding layer 31 The number and installation position vary.

[0088] Specifically, at least one light-shielding layer 31 includes a first light-shielding layer 311 disposed between the second electrode layer 23 and the insulating barrier layer 60 , and a second light-shielding layer 312 disposed between the insulating barrier layer 60 and the encapsulation layer 50 .

[0089] It should be noted that the area of ​​the effective light-shielding region of the light-emitting layer is increased by the first light-shielding layer 311 to enhance the light-shielding ...

Abstract

The invention provides a display panel and a display device, the display panel comprises a light-transmitting area and a display area at least partially surrounding the light-transmitting area, and ashading area is arranged between the display area and the light-transmitting area. An array substrate and a light-emitting layer arranged on the array substrate are arranged in the display area, and at least one light-shielding layer is arranged in the light-shielding area and used for shielding light emitted by the light-emitting layer in the display area from entering the light-transmitting area. Light in the display area can be effectively prevented from being emitted from the light-transmitting area, the light leakage rate of the display panel is reduced, the display effect of the displaypanel and the display effect of the display device are optimized, and meanwhile manufacturing of the display panel with a narrow frame is facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In the current field of display technology, as people have higher and higher requirements for screen-to-body ratio and display effect, full-screen display devices are favored by general users. The full screen can not only improve the appearance of the display device, but also reduce the size of the mobile phone and bring users a better visual experience. [0003] Based on the display device needs to be equipped with additional functional devices such as fingerprint recognition, earpiece, distance sensing sensor, light sensor and camera device, it is necessary to reserve a certain area on the display screen for the setting of additional functional devices. At present, hole structures are provided on some display screens, and the above-mentioned additional functional devices are arranged in the positions ...
