Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Fig. 2 is a schematic diagram of a display panel according to an embodiment of the present invention, and referring to fig. 2, the display panel includes a display region 10, a transition region 20, and a via region 30, the transition region 20 is disposed between the via region 30 and the display region 10, that is, the transition region 20 surrounds the display region 10, and the via region 30 surrounds the transition region 20. The transition area 20 includes a substrate 21, a light-shielding rubber frame 22, and a cover plate 23, which are stacked, the light-shielding rubber frame 22 is disposed between the substrate 21 and the cover plate 23, and the light-shielding rubber frame 22 may be configured to shield light emitted from the display area 10 to the through hole area 30.
As shown in fig. 2, only the cover 23 remains in the through-hole area 30, and the remaining display panel portion is cut away, so that a through-hole is available, which can be used for disposing a camera. The display region 10 may include a substrate 21, a buffer layer 12 formed on the substrate 21, a planarization layer 13 formed on the buffer layer 12 at the same layer, a metal wire 14 and an isolation structure 15, a pixel defining layer 16 formed on the planarization layer 13, and a pixel unit 17 formed on the pixel defining layer 16. In addition, the display region 10 further includes an encapsulation layer 18 covering the above-described structures, so that each structure can be encapsulated and protected. In addition, an IJP (Ink-jet Print) layer 19 is also formed on the encapsulation layer 18 in the region within the isolation structure 15 in the display region 10, and then the respective structures may be encapsulated again. Then, an optical adhesive 110 (OCA) may be coated, and then, a touch layer 111 may be disposed on the optical adhesive 110, and a polarizer 112 may be disposed between the touch layer 111 and the cover plate 23.
It should be noted that fig. 2 only shows each structure in one display panel, and in practical applications, the display panel may further include other structures according to different types, and this is not particularly limited in the embodiment of the present invention.
When the display panel displays a picture, light emitted by the pixel unit 17 can not only be emitted from the front of the display panel, but also a part of the light can be emitted to the through hole area 30 from the display area 10 along an oblique direction, and the light emitted by the display area 10 to the through hole area 30 can be shielded by arranging the light shielding rubber frame 22 on one side of the transition area 20 close to the through hole area 30, as shown in fig. 2, so that in the process of receiving imaging light by the camera, the light can be prevented from interfering the camera, and the imaging quality of the camera is improved.
Optionally, fig. 3 shows a schematic view of another display panel provided in the first embodiment of the present invention, and referring to fig. 3, in another implementation manner, the transition region 20 may further include an encapsulation layer 18, the encapsulation layer 18 is formed on the substrate 21, and accordingly, the light blocking frame 22 may be disposed between the encapsulation layer 18 and the cover plate 23.
In the display panel shown in fig. 3, the light blocking frame 22 may occupy a region where a portion of the encapsulation layer 18 is located, that is, the edge portion of the display region 10 shown in fig. 1 may extend to the transition region 20 to become a portion of the transition region 20, so that the area of the effective display region may be further increased under the condition that the size of the through hole region is determined and the thickness of the light blocking frame 22 is determined, thereby increasing the display area.
Optionally, fig. 4 shows a schematic diagram of a third display panel provided in the first embodiment of the present invention, referring to fig. 4, in a third implementation manner, the transition region 20 may further include an isolation structure 15, the isolation structure 15 is formed on the substrate 21, the encapsulation layer 18 covers the isolation structure 15, and accordingly, the light-shielding rubber frame 22 may be disposed between the encapsulation layer 18 and the cover plate 23. In practical applications, the isolation structure 15 is usually a Dam (Dam), and the isolation structure 15 may surround the via region 30 to block cracks generated by cutting the via, so as to prevent the cracks from extending to the display region 10.
In the display panel shown in fig. 4, the light shielding frame 22 may further occupy the region where the isolation structure 15 is located on the basis of fig. 3, that is, the edge portion of the display region 10 shown in fig. 3 may further extend to the transition region 20 to become a part of the transition region 20, so that the area of the effective display region may be further increased on the basis of fig. 3 in the case that the size of the through hole region is determined and the thickness of the light shielding frame 22 is determined, thereby further increasing the display area.
Further optionally, fig. 5 shows a schematic view of a fourth display panel provided in the first embodiment of the present invention, referring to fig. 5, in a fourth implementation manner, the transition region 20 may further include a polarizer 112, the polarizer 112 is disposed on a side of the cover plate 23 away from the substrate 21, and correspondingly, the light-shielding rubber frame 22 may be disposed between the substrate 21 and the polarizer 112.
Unlike the display panel shown in fig. 2, in the display panel shown in fig. 5, the top of the light-shielding rubber frame 22 is not directly abutted to the cover plate 23, but is abutted to the polarizer 112. Since the thickness of the polarizer 112 is generally small in practical applications and the light emitted from the display region 10 to the through hole region 30 is oblique, it is difficult to emit the light from the thin polarizer 112 to the through hole region 30. Thus, in a specific application, a portion of the polarizer 112 may be remained in the transition region 20, so that the material usage of the light-shielding frame 22 can be reduced while the light-shielding effect is ensured.
Further optionally, fig. 6 shows a schematic diagram of a fifth display panel according to an embodiment of the present invention, referring to fig. 6, in a fifth implementation manner, the transition region 20 further includes a polarizer 112, the polarizer 112 is disposed on a side of the cover plate 23 away from the substrate 21, and correspondingly, the light-shielding rubber frame 22 may be disposed between the encapsulation layer 18 and the polarizer 112.
Unlike the display panel shown in fig. 3, in the display panel shown in fig. 6, the top of the light shielding rubber frame 22 does not directly abut against the cover plate 23, but abuts against the polarizer 112, so that the light shielding effect is ensured and the material consumption of the light shielding rubber frame 22 can be reduced. In addition, unlike the display panel shown in fig. 5, in the display panel shown in fig. 7, the bottom of the light shielding rubber frame 22 is not directly abutted to the substrate 21 but is abutted to the encapsulating layer 18.
Further alternatively, fig. 7 shows a schematic diagram of a sixth display panel provided in an embodiment of the invention, referring to fig. 7, in a sixth implementation manner, similar to the fifth implementation manner, the transition region 20 further includes a polarizer 112, the polarizer 112 is disposed on a side of the cover plate 23 away from the substrate 21, and accordingly, the light-shielding rubber frame 22 may be disposed between the encapsulation layer 18 and the polarizer 112.
Unlike the display panel shown in fig. 4, in the display panel shown in fig. 7, the top of the light shielding rubber frame 22 does not directly abut against the cover plate 23, but abuts against the polarizer 112, so that the light shielding effect is ensured and the material consumption of the light shielding rubber frame 22 can be reduced.
It should be noted that, the foregoing description focuses on differences of the display panels in the drawings, and it is understood that other portions of the display panels may be the same or different, and are determined according to the types of the display panels, and the embodiment of the present invention is not limited to this specifically.
In addition, in a specific application, optionally, the width of the light shielding rubber frame 22 in the direction parallel to the display panel may be greater than or equal to 100 micrometers and less than or equal to 600 micrometers.
It should be noted that, in the display panel shown in fig. 1 to fig. 7, due to the gravity of the light shielding rubber frame 22, the cross section of the light shielding rubber frame 22 in the direction perpendicular to the display panel is trapezoidal, and therefore, the width of the trapezoidal light shielding rubber frame 22 in the direction parallel to the display panel may specifically refer to the maximum width of the light shielding rubber frame 22 in the direction parallel to the display panel, that is, the width of the light shielding rubber frame 22 near the substrate 21, and of course, may also refer to the average width of the light shielding rubber frame 22 in the direction parallel to the display panel, and the like, which is not specifically limited in the embodiment of the present invention.
Alternatively, in practical applications, the material of the light shielding rubber frame 22 may include at least one of Polyimide (PI) and resin. In this case, the same resin material as that of the black matrix (not shown) in the display region 10 can be used as the resin, so that the light shielding performance can be ensured. Of course, in a specific application, the material of the light-shielding rubber frame 22 may also be other light-shielding materials with light-shielding performance, which is not specifically limited in this embodiment of the present invention.
In addition, in practical application, the material of the light shielding rubber frame 22 may be a black material, and certainly, may also be other dark materials, as long as it is ensured that a better light shielding effect can be achieved under a certain thickness, and the embodiment of the present invention is not particularly limited to this.
