Referring to fig. 1, a display screen 10 is provided in an embodiment of the present application. The display screen 10 includes a substrate 110, a light emitting layer 120, and a polarizer 140, wherein the polarizer 140 includes a polarizing portion and a shielding portion 142. The light emitting layer 120 is disposed on one side of the substrate 110. The light emitting layer 120 is provided with openings 130. The polarizer 140 is stacked on a side of the light-emitting layer 120 away from the substrate 110. The polarizing portion and the shielding portion 142 are integrally formed. The shielding part 142 is bent and extended towards the inside of the opening 130, and the shielding part 142 is arranged around the inner wall of the opening 130.
In this embodiment, the substrate 110 may be a rigid material, such as glass. The substrate 110 may also be a flexible material. The substrate 110 may be flexible when made of a flexible material. When the substrate 110 is a flexible material, the substrate may be polyimide, polyethylene naphthalate, polyethylene terephthalate, polyarylate, polycarbonate, polyethersulfone, polyetherimide, or the like.

The opening 130 may extend through the entire display screen 10, and when the display screen 10 is applied in a vehicle, control buttons such as voice and video in some vehicles may pass through the opening 130. The display screen 10 may be fixed to a portion of the vehicle interior through the opening 130, for example, the opening 130 may be sleeved on a columnar boss on the inner wall of the vehicle so as to fix the display screen 10. The shape of the openings 130 may be as desired, and in one embodiment, the openings 130 may be circular, rectangular, oval, polygonal, etc.
The polarizing part may control a polarization direction of a specific light beam emitted from the light emitting layer 120. Thus bringing good visual effect to people. The polarizing part is a part of the polarizer 140, and the polarizer 140 may include a polyvinyl alcohol (PVA) film, a cellulose Triacetate (TAC) film, a protective film, a release film, a pressure-sensitive adhesive film, and the like. Among them, the polyvinyl alcohol film determines the polarizing performance and transmittance of the polarizer 140, and is also a major part affecting the color tone and optical durability of the polarizer 140.
The shielding portion 142 is integrally formed with the polarizing portion, that is, the polarizing portion may be made of the same material as the shielding portion 142. The shielding part 142 may be understood as an extension of the polarizing part. The cellulose triacetate film may be disposed on both sides of the polyvinyl alcohol film to isolate water and air and to protect the polarizing layer. Therefore, the polarizer 140 has a function of isolating water and air. The polarizer 140 may be folded into the opening 130 after extending into the opening 130, and the folded portion may constitute the shielding portion 142. The shielding portion 142 may be disposed closely to the inner wall of the opening 130. In one embodiment, the shielding portion 142 may be adhered to the inner wall of the opening 130 by an adhesive. Accordingly, the blocking portion 142 prevents moisture and air in the opening 130 from entering the light emitting layer 120, thereby preventing damage to the light emitting layer 120.
It is understood that the shielding portion 142 may have the same or different structure as the polarized portion on the surface of the light emitting layer 120. The number of layers of the shielding portion 142 and the number of layers of the polarizing portion may be different. In one embodiment, the number of layers of the shielding part 142 may be less than the number of layers of the polarizing part. Space within the aperture 130 may be saved.
In the display screen 10 according to the embodiment of the present application, the light emitting layer 120 and the polarizing portion are sequentially disposed on one side of the substrate 110, and the light emitting layer 120 is provided with the opening 130. The polarizing portion and the shielding portion 142 are integrally formed. The shielding part 142 is disposed around the inner wall of the opening 130, so that the shielding part 142 can block air and moisture from invading the light emitting layer 120, thereby enabling to improve the reliability of the display screen 10.
Referring to fig. 2, in one embodiment, a light shielding layer 150 is disposed on a side of the shielding portion 142 away from the inner wall of the opening 130. The light emitted from the light emitting layer 120 can be prevented from leaking out of the opening 130 by the light shielding layer 150. The light shielding layer 150 may be black or gray. The light shielding layer 150 may be a coating coated on the inner wall of the opening 130, or may be a film layer adhered on the inner wall of the opening 130. In one embodiment, the light shielding layer 150 may be ink. In one embodiment, the top of the opening may also be provided with a light shielding element to avoid light leakage from the opening 130. When the opening is covered by the cover plate 180, the ink may be applied to the side of the cover plate 180 near the opening 130, so as to prevent light leakage, and when the ink is applied to the top of the cover plate 180, the substrate 110 may be a transparent substrate. The camera provided with the opening 130 may collect images from the direction of the transparent substrate.
In one embodiment, the display screen 10 further includes a touch layer 160. The touch layer 160 is disposed on a side of the light emitting layer 120 away from the substrate 110. The polarizer 140 is disposed on a side of the touch layer 160 away from the light emitting layer 120. The openings 130 penetrate through the touch layer 160 and the light-emitting layer 120. The shielding portion 142 extends from the touch layer 160 to the light emitting layer 120. The touch control layer 160 may be used as an input function module of the display screen 10. The touch layer 160 may be a capacitive touch layer. The touch layer 160 may function to control the display screen 10 by touching. The openings 130 are disposed through the touch layer 160 and the light emitting layer 120. Therefore, the shielding portion 142 also serves to protect the edge of the touch layer 160.
Referring to fig. 3, in one embodiment, a side of the touch layer 160 adjacent to the opening 130 is provided with a first bump structure 162 surrounding the opening 130. The first projection arrangement 162 may be an annular projection around the inner wall of the opening 130. A portion of the blocking portion is adhered to a surface of the first bump structure 162. Accordingly, the surface area of the shielding part 142 is relatively increased under the support of the first protrusion structure 162, and accordingly, the difficulty of intrusion of moisture and air into the light emitting layer 120 is increased, thereby further increasing the reliability of the display screen 10. In one embodiment, the first bump structure 162 may be integrally formed with the touch layer 160. The first bump structure 162 may also be a separate structure adhered to the edge of the touch layer 160. In one embodiment, the first bump structure 162 may be an organic adhesive adhered to the light emitting layer 120 at the edge of the opening 130. The organic gel may form the first bump structures 162 after curing.
In one embodiment, the display 10 further includes an adhesive layer 170. The adhesive layer 170 is disposed between the light emitting layer 120 and the touch layer 160. The opening 130 penetrates through the touch layer 160, the light emitting layer 120 and the adhesive layer 170. The adhesive layer 170 may be an optical adhesive, an organic resin, or the like. The adhesive layer 170 may connect the light emitting layer 120 and the touch layer 160. The thickness of the adhesive layer 170 near the edge of the opening 130 may be slightly greater than the thickness of the adhesive layer 170 at other positions, so that the contact area between the adhesive layer 170 and the shielding portion 142 may be increased at the edge of the adhesive layer 170 near the opening 130. The blocking portion 142 can be fixed by the adhesive layer 170.
In one embodiment, the adhesive layer 170 is provided with a second raised structure 172 surrounding the aperture 130 on a side adjacent to the aperture 130. The second protrusion 172 may be an annular structure disposed around the inner wall of the opening 130. The second protrusion structure 172 may change the shape of the inner wall of the opening 130, so that the shielding portion 142 may also protrude along with the protrusion of the inner wall of the opening 130. The protruding shielding portion 142 increases the area of the shielding portion 142, and may also lengthen the path of moisture and air intrusion, thereby reducing the possibility of water and air intrusion into the light emitting layer 120. In one embodiment, the second raised structures 172 may be raised to a greater extent than the first raised structures 162. Therefore, the first protruding structures 162 and the second protruding structures 172 may make the inner wall of the opening 130 have a non-uniform wave shape, so that the path of water and air penetrating into the light-emitting layer 120 is more tortuous, the path is correspondingly longer, and the resistance of water and oxygen penetrating into the light-emitting layer 120 is further increased.
In one embodiment, the surface of the second raised structure 172 is a frosted surface. Since the second protrusion structures 172 are formed of a gel, the second protrusion structures 172 may polish the surface of the second protrusion structures 172 to form the frosted surface when not completely cured. The frosted surface may increase the area of the surface of the second protrusion structure 172, thus increasing the contact area of the second protrusion structure 172 and the shielding part 142. Further, the frosted surface increases static friction between the surface of the second protrusion structure 172 and the shielding part 142, and thus may improve adhesion of the shielding part 142 to the second protrusion structure 172.
The frosted surface may be a continuous undulating protrusion or recess, and when the shielding part 142 is adhered to the inner wall of the opening 130, a small gap is left between the shielding part 142 and the protrusion or recess. When moisture intrudes into the frosted surface, it is left in the voids, so that the voids can prevent further intrusion of water oxygen into the light emitting layer 120.
In one embodiment, the polarizer 140 includes at least one layer of cellulose triacetate film. The shielding portion 142 is formed of the cellulose triacetate film. The cellulose triacetate film has a function of blocking moisture and air. At the shielding portion 142, other layers of the polarizer 140 are peeled off, leaving only one layer of the triacetyl cellulose film. The cellulose triacetate film can function as both a barrier to moisture and oxygen permeation and also reduce the thickness of the shielding part 142, so that the resistance to bending the shielding part 142 toward the opening 130 can be reduced. The use of the cellulose triacetate film to make the shielding portion 142 can reduce the volume occupied by the shielding portion 142 and increase the space in the opening 130.
In one embodiment, the display screen 10 further includes a cover plate 180. The cover plate 180 covers a surface of the polarizing portion, which is far away from the substrate 110. The cover 180 is sealed with the edge of the opening 130 by a sealant. It is possible to prevent moisture and air from entering the light emitting layer 120 through the gap between the cover plate 180 and the opening 130. The cover plate 180 may function to seal and protect the touch layer 160. The sealant may be an optical organic adhesive. The cover plate 180 may seal the opening 130. The sealant can increase the adhesion of the change 180 and the opening edge of the opening 130, and has a sealing function to prevent moisture and oxygen from entering the opening 130 through a gap between the cover 180 and the touch layer 160.
The embodiment of the application also provides a display device. The display device comprises the display screen 10 provided by the embodiment. The display device can be a tablet personal computer, a mobile terminal, an intelligent bracelet and other electronic equipment. The display device may also be used as an in-vehicle display device.
