Problems solved by technology

[0005] However, the black ink coated on the white film often has the problem of uneven coloring or easy fading and delamination, which will inevitably affect the light-shielding performance
In addition, the above-mentioned production process must wait for the black ink to dry before proceeding to the next production process such as adding glossy or matte treatment to the surface of the black ink, but it is obvious that this is a waste of time
[0006] In addition, the black ink coated on the white film is very easy to leave fingerprints due to the touch of the assembly personnel. At this time, it must be wiped with cleaning products such as alcohol solvents, and the black ink is often wiped off or wiped off. Contaminate the product, thereby affecting the shading effect and aesthetics of the black and white double-sided shading film

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] figure 1 It is an exploded schematic view of the frame light-shielding adhesive film of the present invention. As shown in the figure, the present invention is an outer frame light-shielding adhesive film 1 of a display screen, which can be adhered to a hollow outer frame light-shielding adhesive film 1 around the display screen 2. The outer frame light-shielding adhesive film 1 is formed of a white plastic. The diaphragm 122 and a black diaphragm 121 formed of black plastic are formed by bonding the adhesive 124 to each other.

[0021] image 3 It is a schematic cross-sectional view of the light-shielding double-layer adhesive film for the outer frame of the present invention. An adhesive layer 125 is disposed on the other surface of the white film 122 opposite to the black film 121 , and a release paper (film) 123 is covered on th...

Abstract

The invention relates to an outer frame shading adhesive film for a display screen. The outer frame shading adhesive film comprises a hollow outer frame shading adhesive film which is adhered to the periphery of the display screen, and is characterized in that: the outer frame shading adhesive film consists of a white diaphragm molded by a white plastic and a black diaphragm molded by a black plastic, which are adhered by an adhesive. The outer frame shading adhesive film is adhered to the periphery of the display screen, can prevent light ray exposure on the edges of the display screen, and can make a luminous element of a backlight module accurately project the concentrated light rays on the display screen. Meanwhile, in order to make an assembler tear the outer frame shading adhesive film easily and accurately adhere the adhesive film to the periphery of the display screen, a release film and a tearing part are arranged on two sides of the outer frame shading adhesive film, and the assembly process can be effectively simplified and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a light-shielding adhesive film for an outer frame of a display screen, in particular to a light-shielding adhesive film for an outer frame of a display screen that enables a light-emitting element of a backlight module to reliably project concentrated light on the display screen. Background technique [0002] At present, with the continuous development of technology, the obsolete traditional cathode ray tube display CRT technology has been eliminated in display technology, and the display has gradually evolved into LCD liquid crystal display of flat panel display technology. Today's mature LCD liquid crystal display technology has had a revolutionary impact on personal computers and home appliances. LCD liquid crystal display technology has entered the stage of large-scale popularization, and this trend has gradually derived to the mobile phone market. [0003] Mobile phone liquid crystal displays mainly use light-emitting di...
