Description
Technical Field
The invention relates to a cover plate structure of a display screen.
Background
With the wider application range of intelligent products, the requirements of some products on the display area are gradually increased, and the requirements only require penetration rate. For example, electronic products such as a bracelet require that a display area needs to be printed with a layer of IR (infrared radiation) ink to screen infrared rays, so as to assist in judging whether the display area of the electronic product contacts a human face or other parts, and accordingly, corresponding control is performed. However, the IR ink is a semi-transparent ink, and when the IR ink is printed on the surface of the display area, problems such as uneven color and particle impurities occur, which seriously affects the yield of the product.
Disclosure of Invention
Accordingly, there is a need for a cover plate structure of a display panel with high yield.
A cover plate structure of a display screen comprises cover plate glass, an optical adhesive layer, an IR film layer and a frame ink layer; a display area and an IR hole area are formed on the surface of the cover plate glass, the IR hole area is adjacent to the display area, the cover plate glass, the optical adhesive layer and the IR film layer are sequentially stacked, and the optical adhesive layer is positioned on the bottom surface of the cover plate glass; the frame ink layer is arranged between the cover plate glass and the optical adhesive layer, between the optical adhesive layer and the IR film layer and on one of the bottom surfaces of the IR film layer.
In one embodiment, the cover glass is curved glass, and the optical adhesive layer and the IR film layer are sequentially attached to the bottom surface of the cover glass.
In one embodiment, the frame ink layer is projected on the surface of the cover glass to form a frame area, the frame area is located at the periphery of the cover glass and surrounds the display area, and the IR hole area is located on the frame area.
In one embodiment, the thickness of the optical adhesive layer is 0.025 mm to 0.5 mm.
In one embodiment, the thickness of the frame ink layer is 5 to 35 microns.
In one embodiment, the IR film layer has a thickness of 0.025 mm to 0.2 mm.
In one embodiment, the peripheral edge of the IR film layer is shrunk inward relative to the peripheral edge of the cover glass.
In one embodiment, the peripheral edge of the IR film layer is shrunk inward by a distance of 0.2mm to 0.5mm relative to the peripheral edge of the cover glass.
In one embodiment, the IR film layer is made of a semi-permeable film material.
In one embodiment, the material of the IR film layer is PET, TAC or PMMA.
Because the IR film layer is adhered to the bottom surface of the cover plate glass through the optical adhesive layer, compared with the IR printing ink printed on the surface of the cover plate glass, the IR film layer on the bottom surface of the cover plate glass cannot influence the color of the display area on the cover plate glass, and cannot generate granular sensation, so that the yield of the cover plate structure of the display screen is high.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The invention relates to a cover plate structure of a display screen. For example, the cover plate structure of the display screen comprises cover plate glass, an optical adhesive layer, an IR film layer and a frame ink layer. For example, a display area and an IR hole area are formed on the surface of the cover glass, the IR hole area is adjacent to the display area, and the cover glass, the optical adhesive layer and the IR film layer are sequentially stacked. For example, the optical adhesive layer is positioned on the bottom surface of the cover glass; the frame ink layer is arranged between the cover plate glass and the optical adhesive layer, between the optical adhesive layer and the IR film layer and on one of the bottom surfaces of the IR film layer. For another example, a cover plate structure of a display screen includes cover plate glass, an optical adhesive layer, an IR film layer, and a frame ink layer. For example, the cover glass has a display area and an IR aperture area formed on a surface thereof, the IR aperture area being adjacent to the display area. For example, the cover glass, the optical adhesive layer and the IR film layer are sequentially stacked, and the optical adhesive layer is located on the bottom surface of the cover glass. For example, the optical adhesive layer is a transparent optical adhesive, and the frame ink layer is disposed between the cover glass and the optical adhesive layer, between the optical adhesive layer and the IR film layer, or on one of the bottom surfaces of the IR film layer.
Referring to fig. 1 to 4, a cover plate structure 100 of a display screen includes a cover plate glass 10, an optical adhesive layer 20, an IR film layer 30, and a frame ink layer 40; a display area 11 and an IR hole area 13 are formed on the surface of the cover glass, the IR hole area is adjacent to the display area, the cover glass, an optical adhesive layer and an IR film layer are sequentially stacked, and the optical adhesive layer is positioned on the bottom surface of the cover glass; the frame ink layer is arranged between the cover plate glass and the optical adhesive layer, between the optical adhesive layer and the IR film layer and on one of the bottom surfaces of the IR film layer.
Because the IR film layer is adhered to the bottom surface of the cover plate glass through the optical adhesive layer, compared with the IR printing ink printed on the surface of the cover plate glass, the IR film layer on the bottom surface of the cover plate glass cannot influence the color of the display area on the cover plate glass, and cannot generate granular sensation, so that the yield of the cover plate structure of the display screen is high.
For example, in order to make the frame of the cover glass more clearly displayed, the cover glass is curved glass, and the optical adhesive layer and the IR film layer are sequentially attached to the bottom surface of the cover glass; namely, the optical adhesive layer is attached to the bottom surface of the cover plate glass, and the IR film layer is attached to the surface of the optical adhesive layer away from the bottom surface of the cover plate glass. The frame ink layer is projected on the surface of the cover glass to form a frame area 15, the frame area is located on the periphery of the cover glass and surrounds the display area, and the IR hole area is located on the frame area. For example, a cover plate structure of a display screen includes cover plate glass, an optical adhesive layer, an IR film layer, and a frame ink layer; a display area is formed on the surface of the cover plate glass, the IR film layer is attached to the bottom surface of the cover plate glass through the optical adhesive layer, and the optical adhesive layer is positioned on the bottom surface of the cover plate glass; the frame ink layer is arranged on the bottom surface of the IR film layer, the cover plate glass is curved glass, a frame area 15 is formed by projection of the frame ink layer on the surface of the cover plate glass, and the frame area is located on the periphery of the cover plate glass and surrounds the display area. The frame printing ink layer is arranged on the bottom surface of the cover plate glass, so that the frame printing ink can form a frame area on the surface of the cover plate glass in a projection mode.
For example, in order to improve the transmittance, the thickness of the optical adhesive layer is 0.025 mm to 0.5 mm. The thickness of the frame ink layer is 5-35 microns. The thickness of the IR film layer is 0.025 mm-0.2 mm. A cover plate structure of a display screen comprises cover plate glass, an optical adhesive layer, an IR film layer and a frame ink layer; a display area and an IR hole area are formed on the surface of the cover plate glass, the IR hole area is adjacent to the display area, the IR film layer is attached to the bottom surface of the cover plate glass through the optical adhesive layer, and the optical adhesive layer is positioned on the bottom surface of the cover plate glass; the frame ink layer is arranged between the optical adhesive layer and the IR film layer, the cover plate glass is curved glass, the optical adhesive layer and the IR film layer are sequentially attached to the bottom surface of the cover plate glass, and the thickness of the optical adhesive layer is 0.025 mm-0.5 mm. The thickness of the frame ink layer is 5-35 microns, and the thickness of the IR film layer is 0.025-0.2 mm. Through the design of the thickness of the optical adhesive layer, the thickness of the frame ink layer and the thickness of the IR film layer, the penetration rate of the cover plate structure of the display screen is high.
For example, the peripheral edge of the IR film layer is shrunk inward with respect to the peripheral edge of the cover glass in order to conform to the shape of the cover glass. The peripheral edge of the IR film layer is shrunk inwards by a distance of 0.2-0.5 mm relative to the peripheral edge of the cover glass. A cover plate structure of a display screen comprises cover plate glass, an optical adhesive layer, an IR film layer and a frame ink layer; a display area and an IR hole area are formed on the surface of the cover plate glass, the IR hole area is adjacent to the display area, the cover plate glass, the optical adhesive layer and the IR film layer are sequentially stacked, and the optical adhesive layer is positioned on the bottom surface of the cover plate glass; the frame ink layer is arranged between the cover plate glass and the optical adhesive layer, the cover plate glass is curved glass, the optical adhesive layer and the IR film layer are sequentially attached to the bottom surface of the cover plate glass, and the periphery of the IR film layer is inwards shrunk relative to the periphery of the cover plate glass. The peripheral edge of the IR film layer is shrunk inwards by a distance of 0.2-0.5 mm relative to the peripheral edge of the cover glass. The IR film layer is contracted relative to the cover plate glass, so that the IR film layer is not protruded out of the edge of the cover plate glass and is matched with the cover plate glass, and the IR film layer is prevented from falling off due to external force.
For example, in order to improve the display effect, the transmittance of the IR film layer to visible light of 380 nm-650 nm is 0% -20%. The IR film layer has a transmittance of 80% or more with respect to visible light of 800 nm to 1000 nm. For example, a cover plate structure of a display screen includes cover plate glass, an optical adhesive layer, an IR film layer, and a frame ink layer; a display area and an IR hole area are formed on the surface of the cover plate glass, the IR hole area is adjacent to the display area, the cover plate glass, the optical adhesive layer and the IR film layer are sequentially stacked, and the optical adhesive layer is positioned on the bottom surface of the cover plate glass; the frame ink layer is arranged between the cover plate glass and the optical adhesive layer, the cover plate glass is curved glass, the optical adhesive layer and the IR film layer are sequentially attached to the bottom surface of the cover plate glass, and the penetration rate of the IR film layer to 380-650 nm visible light is 0-20%. The IR film layer has a transmittance of 80% or more with respect to visible light of 800 nm to 1000 nm. Through the design of the penetration rate of the IR film layer, the display effect of the cover plate structure of the display screen is better.
For example, in order to conveniently manufacture the IR film layer, the material of the IR film layer is a semi-permeable film such as PET (Polyethylene terephthalate), TAC (triallyl cyanurate), or PMMA (polymethyl methacrylate). For example, a cover plate structure of a display screen includes cover plate glass, an optical adhesive layer, an IR film layer, and a frame ink layer; a display area and an IR hole area are formed on the surface of the cover plate glass, the IR hole area is adjacent to the display area, the cover plate glass, the optical adhesive layer and the IR film layer are sequentially stacked, and the optical adhesive layer is positioned on the bottom surface of the cover plate glass; the frame ink layer is arranged between the cover plate glass and the optical adhesive layer, between the optical adhesive layer and the IR film layer and on the bottom surface of the IR film layer, the cover plate glass is curved glass, the optical adhesive layer and the IR film layer are sequentially attached to the bottom surface of the cover plate glass, and the IR film layer is made of a semi-transparent film material such as PET, TAC or PMMA. The material of the IR film layer is set to be PET, TAC or PMMA, so that the IR film layer is easier to manufacture and more common in material selection.
For example, in one embodiment, the display screen is a flat panel display. For example, in another embodiment, the display screen is a curved glass screen, wherein in order to conform to the shape of the curved glass screen, the cover glass is curved glass, and the optical adhesive layer and the IR film layer are sequentially attached to the bottom surface of the cover glass; the optical adhesive layer is attached to the bottom surface of the cover plate glass, and the IR film layer is attached to one surface, far away from the bottom surface of the cover plate glass, of the optical adhesive layer. The frame ink layer is projected on the surface of the cover plate glass to form a frame area, the frame area is located on the periphery of the cover plate glass and surrounds the display area, and the IR hole area is located on the frame area. The cover plate structure of the display screen comprises cover plate glass, an optical adhesive layer, an IR film layer and a frame ink layer; a display area is formed on the surface of the cover plate glass, the IR film layer is attached to the bottom surface of the cover plate glass through the optical adhesive layer, and the optical adhesive layer is positioned on the bottom surface of the cover plate glass; the frame printing ink layer is arranged on the bottom surface of the IR film layer, the cover plate glass is curved surface glass, the frame printing ink layer is projected on the surface of the cover plate glass to form a frame area, the surface of the frame area is a curved surface, and the frame area is located on the periphery of the cover plate glass and surrounds the display area. Because the surface of the frame area is a curved surface, a better appearance effect can be realized.
For example, the present disclosure mainly uses an IR Film technology to replace IR ink, so as to solve some problems occurring in large-area printing of IR ink, the structure mainly comprises two functional layers, which are OCA (optically clear adhesive) and IRFilm (infrared Film), and the IR Film with IR function is attached to CG (cover glass) ink surface (covering window and IR hole region) by means of external attachment, so that there is no defect of conventional technology in appearance, and the structure is not limited by the size of the product, and can basically satisfy all sizes of the existing touch display product, and the IR Film material can be a semi-transparent Film such as PET, TAC or PMMA.

(2) The IR film is positioned on the lower surface of the CG and is connected through an optical transparent adhesive.
(3) The IR film can be used for decorating a frame with a BM (black matrix), and the thickness of the optical adhesive is 0.025-0.5 mm.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
