Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Further, in the exemplary embodiments, since the same reference numerals denote the same components having the same structure or the same steps of the same method, if an embodiment is exemplarily described, only a structure or a method different from the already described embodiment is described in other exemplary embodiments.
Throughout the specification and claims, when one element is described as being "connected" to another element, the one element may be "directly connected" to the other element or "electrically connected" to the other element through a third element. Furthermore, unless explicitly described to the contrary, the term "comprising" and its corresponding terms should only be taken as including the stated features, but should not be taken as excluding any other features.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present disclosure. As shown in fig. 1, the display panel includes: the light-emitting film layer 1, the second glue layer 5, the polaroid 2, the first glue layer 4 and the cover plate 3 are stacked. The polaroid 2 is arranged on the light-emitting side of the light-emitting film layer 1, the cover plate 3 is arranged on one side of the polaroid 2, which is far away from the light-emitting film layer 1, the first glue layer 4 is arranged between the polaroid 2 and the cover plate 3, the second glue layer 5 is arranged between the light-emitting film layer 1 and the polaroid 2, and the polaroid 2 comprises a through hole 20 which penetrates through the polaroid 2 along the film layer laminating direction; wherein the first glue layer 4 and the second glue layer 5 together fill the through hole 20.
At present, more and more display panels have a camera shooting or photographing function, for example, display panels on display devices such as mobile phones and flat panels, and in order to place devices such as cameras, corresponding holes are required to be formed in positions on the display panels for placing corresponding devices. The blind hole technology is an important technology for narrow-frame and frameless display panels, and by arranging the blind holes which do not completely penetrate through the display panel, the installation of functional devices such as camera shooting and photographing can be realized, and the narrow-frame or frameless display panel can also be realized, so that the blind hole technology also becomes a key technology of the current large-screen display panel. Usually the blind hole sets up in the non-display area of luminous rete, correspond the camera position, and the through-hole on the polaroid sets up on the blind hole, the internal diameter of through-hole on the polaroid can be bigger than the blind hole internal diameter by 0.2mm-0.5mm, in order to avoid influencing the formation of image in camera hole, however the through-hole on the polaroid still needs to be filled after seting up, because the air in the through-hole can lead to the polaroid and other rete laminating in the through-hole position bubble production, thereby influence the display effect, and still probably damage display panel in leading to subsequent performance test, thereby cause the promotion of defective rate. The current display panel adopts glue filling to solve the problems, however, the glue in the market is basically glue with a thickness less than 0.2mm, and the glue with a thickness greater than 0.2mm can generate glue pulling phenomenon, and in order to avoid glue pulling, the thickness of the selected glue is less than 0.2mm, so that the depth of the through hole which can be filled with the filling glue has an upper limit (for example, the depth of the through hole which can be filled with the filling glue with a thickness of 0.2mm and a filling rate of 50% is 0.1 mm), that is, the thickness of the polarizer has an upper limit (equivalent to the depth of the through hole). The thickness of the polarizer is usually greater than 0.1 mm, which results in that the through holes are not completely filled, and the air remaining in the through holes still generates bubbles and affects the display effect of the display panel. In order to solve the problem, in the embodiment of the application, the first adhesive layer 4 and the second adhesive layer 5 are respectively disposed on two sides of the polarizer 2 (i.e., two ends of the through hole 20), the through hole 20 is filled from one end of the through hole 20 by using the first adhesive layer 4, and the through hole 20 is filled from the other end of the through hole 20 by using the second adhesive layer 5, so that the depth of the through hole 20 which can be filled by the first adhesive layer 4 and the second adhesive layer 5 is the sum of the filling thicknesses of the first adhesive layer 4 and the second adhesive layer 5, that is, the filling thicknesses of the first adhesive layer 4 and the second adhesive layer 5 can be completely filled in the through hole 20 as long as the filling thicknesses are greater than or equal to half of the through hole 20, that is, the first adhesive layer 4 and the second adhesive layer 5 jointly fill the through hole 20 and do not generate a glue pulling phenomenon.
According to the display panel provided by the embodiment of the invention, the first adhesive layer 4 and the second adhesive layer 5 are respectively arranged on the two sides of the polarizer 2 along the film layer laminating direction, and the first adhesive layer 4 and the second adhesive layer 5 are used for jointly filling the through hole 20 on the polarizer 2, so that the maximum depth of the through hole 20 which can be filled is the filling thickness of the first adhesive layer 4 plus the filling thickness of the second adhesive layer 5, the phenomenon of glue pulling can be avoided, the first adhesive layer 4 and the second adhesive layer 5 can be ensured to completely fill the through hole 20, and the problems of poor display and the like caused by bubbles generated in the through hole 20 area during laminating can be avoided.
In an embodiment, the sum of the maximum filling thickness of the first glue layer 4 and the maximum filling thickness of the second glue layer 5 may be greater than or equal to the depth of the through hole 20. In order to ensure that the first adhesive layer 4 and the second adhesive layer 5 can completely fill the through hole 20 and avoid air remaining in the through hole 20, the sum of the maximum filling thickness of the first adhesive layer 4 and the maximum filling thickness of the second adhesive layer 5 can be equal to the depth of the through hole 20, so that the through hole 20 can be completely filled; because first glue film 4 and second glue film 5 are flexible material, in order to guarantee that the air in the through-hole 20 is discharged completely, can set up the maximum filling thickness of first glue film 4 and the maximum filling thickness of second glue film 5 and sum and be greater than the degree of depth of through-hole 20, just so can arrange the air in the through-hole 20 to the greatest extent through the filling extrusion of first glue film 4 and second glue film 5, thereby realize the complete filling of through-hole 20, thereby avoid the regional bubble of production of through-hole 20 when the laminating and the bad scheduling problem of demonstration that causes.
