Description

Technical Field

[0001] The utility model relates to the display field, in particular to an ink protection cover plate. Background Art

[0002] At present, a protective cover is provided on the outermost surface of a display screen or a touch screen to protect the display screen or the touch screen from being scratched. A layer of frame ink is silk-screened on the outer periphery of the back of the protective cover to shield the non-display area of ​​the display screen or the touch screen. During the assembly of the whole machine, the area of ​​the protective cover where the frame ink is silk-screened needs to be bonded and fixed to the whole machine casing.

[0003] However, the protective cover often has problems with not being firmly glued to the entire machine housing due to the dyne value of the frame ink not meeting the standard, or the frame ink falling off due to being hit by foreign objects during the assembly process. The dyne value does not meet the standard because the frame ink is contaminated by grease or other pollutants during the later transportation and assembly process, and the frame ink falls off because the hardness of the frame ink itself is not high, and when it hits an object with higher hardness during assembly, it will fall off or be scratched.

In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0026] like Figure 1 and 2 As shown, an ink protection cover plate 10 includes:

[0027] The protective cover plate 10 includes a light-transmitting area and an ink area 12, wherein the ink area 12 surrounds the periphery of the light-transmitting area;

[0028] A frame ink 20 is disposed on the back of the protective cover 10 and corresponds to the ink area 12;

[0029] The peelable protective layer 30 is disposed on the back side of the frame ink 20 .

[0030] The ink protection cover plate 10 of the utility model is provided with the peelable protective layer 30 on the back side of the frame ink 20. The peelable protective layer 30 can protect the frame ink 20 to prevent the frame ink 20 from being polluted by grease or other pollutants during rear-end transportation and assembly, thereby causing the dyne value to be substandard, and to prevent the frame ink 20 from being knocked off or scratched by foreign objects. When bonding and fixing with the entire machine casing, the peelable protective layer 30 is firstly peeled off from the frame ink 20, and then double-sided tape is affixed to the frame ink 20 to bond and fix it with the entire machine casing.

[0031] The peelable protective layer 30 may be, but is not limited to, peelable glue or peelable glue ink.

[0032] The peelable adhesive is usually an adhesive, which can be solvent-based or water-based, and is directly coated on the back of the frame ink 20, or attached to the back of the frame ink 20 in the form of a tape. After curing, it can form a protective film on the surface of the object, which can be peeled off in one piece without leaving any residue. The composition of the peelable adhesive may include synthetic rubber, acrylic acid or other polymer materials.

[0033] The peelable adhesive ink is a special ink, usually oily, which is coated on the back of the frame ink 20 by screen printing and solidified under ultraviolet (UV) radiation to form a protective film.

[0034] In this embodiment, the peelable adhesive is preferably UV adhesive or thermal adhesive. The viscosity of the UV adhesive will drop sharply under ultraviolet rays, while the viscosity of the thermal adhesive will drop sharply under high temperature. The UV adhesive and thermal adhesive have the property of dropping sharply under certain conditions, which can facilitate their peeling off from the frame ink 20.

[0035] In this embodiment, the peelable adhesive ink is a peelable blue adhesive ink, a water-based peelable adhesive ink or a halogen-free peelable blue adhesive ink, which can be directly adhered to and peeled off with adhesive paper. For example, the temporary protective ink produced and sold by Zhongjingxin Electronic Technology Co., Ltd. includes water-based, oil-based, solvent-based, halogen-free peelable blue adhesive series; the UV-type peelable blue protective adhesive ink produced and sold by Shenzhen Zhihua Electric Technology Co., Ltd. is model ELECT-5030; the peelable blue adhesive ink produced and sold by Shenzhen Shengtianfeng Technology Co., Ltd. is model Capiton-201X-XX.

[0036] The frame ink 20 includes a laminating area 23 and a non-laminating area 24 , and the laminating area 23 surrounds the periphery of the non-laminating area 24 .

[0037] Preferably, the peelable protective layer 30 corresponds to the laminating area 23 .

[0038] In order to reduce material costs, in this embodiment, the peelable protective layer 30 is only covered on the bonding area 23 of the frame ink 20 for bonding and fixing with the entire machine casing.

[0039] The frame ink 20 has a thickness of less than 20 um and includes a colored ink 21 and a bottom cover ink. The colored ink 21 is disposed on the back of the protective cover plate 10 , and the bottom cover ink is disposed on the back of the colored ink 21 .

[0040] The colored ink 21 is used to provide a main body color for the frame ink 20 , and the bottom covering ink is used to cover the colored ink 21 to reduce the light transmittance of the colored ink 21 .

[0041] In this embodiment, the colored ink 21 is white ink or black ink, and the bottom cover ink is semi-transparent cover ink 22 .

[0042] In this embodiment, the protective cover plate 10 may be, but is not limited to, a glass cover plate, a plastic cover plate or a sapphire cover plate.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
