Description

Technical Field

[0001] The utility model relates to the technical field of IML cover, in particular to a light-transmitting IML cover. Background Art

[0002] For translucent components produced by IML two-color injection molding, their transmittance and color coordinate values are subject to a variety of factors, including the influence of smoked transparent plastic, two-component transparent film, and smoke-gray ink. The luminous electronic light guide plate is also a very important influencing factor. Conventional injection molding surfaces use transparent PC materials, but their transmittance fluctuates greatly. In addition, after the smoke-gray ink is printed in the conventional printing scheme, it is easily subjected to irregular flow after being baked by the high-temperature plastic particle flow during the injection molding process, resulting in the offset of the character color coordinates and large fluctuations. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a light-transmitting IML cover, which can reduce the fluctuation of transmittance and the fluctuation of character color coordinates.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a translucent IML cover, including: a diaphragm, an outer translucent plastic plate is laminated to one side of the diaphragm, a dark black ink layer is provided on the other side of the diaphragm, a smoky gray ink layer is provided on one side of the dark black ink layer, a high-temperature resistant transparent ink layer is provided on one side of the smoky gray ink layer, an inner plastic plate is provided on one side of the high-temperature resistant transparent ink layer, and the inner plastic plate is provided with a character area for displaying characters and a light area for illuminating the environment.

[0005] Preferably, the outer light-transmitting plastic plate is organic glass.

[0006] Preferably, the inner plastic plate is ABS plastic.

[0007] Preferably, a first adhesive layer is provided between the outer light-transmitting plastic plate and the membrane, so that the membrane is fully bonded to the outer light-transmitting plastic plate through the first adhesive layer.

[0008] Preferably, a second adhesive layer is provided between the high temperature resistant transparent ink layer and the inner plastic plate.

[0009] Preferably, the dark black ink layer, the smoke gray ink layer, and the high temperature resistant transparent ink layer are provided with air-avoiding areas matching the lighting areas, so that light can penetrate the membrane and the outer light-transmitting plastic plate.

[0010] Preferably, the characters are printed on the smoke-gray ink layer, and the dark black ink layer is provided with an airtight area matching the character area, so that light passes through the high-temperature resistant transparent ink layer, the smoke-gray ink layer and the outer light-transmitting plastic plate.

[0011] Preferably, a texture area and a transparent area are respectively arranged on one side of the outer transparent plastic plate away from the inner plastic plate, and the transparent area corresponds to the lighting area.

[0012] Preferably, the texture area corresponds to the character area.

[0013] The beneficial effects of the present utility model are as follows: Through the combination of PMMA organic glass and the diaphragm, its transmittance is controlled within a fluctuation of ±2%. By printing a layer of high-transparency and high-temperature-resistant high-temperature transparent ink layer on the smoky gray ink layer, the impact of high temperature on the smoky gray ink layer is reduced, thereby reducing its softening and flowing, so that the color coordinates of the characters can ultimately meet the fluctuation of ±1%.

[0024] Examples:

[0025] Reference Figure 1, A light-transmitting IML face cover, comprising: a diaphragm 1, with an outer light-transmitting plastic plate 2 attached to one side of the diaphragm 1, a deep black ink layer 3 printed on the other side of the diaphragm 1, a smoky gray ink layer 4 printed on one side of the deep black ink layer 3, a high-temperature resistant transparent ink layer 5 printed on one side of the smoky gray ink layer 4, and an inner plastic plate 6 attached to one side of the high-temperature resistant transparent ink layer 5. A character area 7 for displaying characters and a lighting area 8 for illuminating the environment are provided on the inner plastic plate 6. The light of the light source passes through the character area 7 and the lighting area 8.

[0026] Reference Figure 1 , To address the characteristic of large fluctuations in the transmittance of conventional PC plastics, the outer light-transmitting plastic plate 2 is PMMA, i.e., plexiglass, and its transmittance can be controlled within a fluctuation of ±2%. However, the melting points of the plexiglass and the diaphragm 1 of the PC substrate differ by nearly 50°C. Therefore, the plexiglass and the diaphragm 1 cannot be combined. Through a first adhesive layer 9 attached between the outer light-transmitting plastic plate 2 and the diaphragm 1, the diaphragm 1 is thus fully combined with the outer light-transmitting plastic plate 2 through the first adhesive layer 9, and the first adhesive layer 9 can be an adhesive.

[0027] Reference Figure 1 , The inner plastic plate 6 is an ABS plastic, and a second adhesive layer 10 is attached between the high-temperature resistant transparent ink layer 5 and the inner plastic plate 6, thereby combining the inner plastic plate 6 with the diaphragm 1 through the second adhesive layer 10. The second adhesive layer 10 can be an adhesive.

[0028] Reference Figure 1 , The deep black ink layer 3, the smoky gray ink layer 4, and the high-temperature resistant transparent ink layer 5 are provided with clearance areas that cooperate with the lighting area 8, so that the light of the lighting source penetrates the diaphragm 1 and the outer light-transmitting plastic plate 2 to illuminate the surrounding environment. When arranging the deep black ink layer 3, the smoky gray ink layer 4, and the high-temperature resistant transparent ink layer 5 on the diaphragm 1, clearance can be made in the area corresponding to the lighting area 8.

[0029] Reference Figure 1 , The characters are printed on the smoky gray ink layer 4, and the deep black ink layer 3 is provided with a clearance area that cooperates with the character area 7, so that the light of the character light source passes through the high-temperature resistant transparent ink layer 5, the smoky gray ink layer 4, the diaphragm 1, and the outer light-transmitting plastic plate 2 to illuminate the characters printed on the smoky gray ink layer 4. When arranging the deep black ink layer 3 on the diaphragm 1, clearance can be made in the area corresponding to the character area 7. When the character light source is turned off, since the characters are printed on the smoky gray ink layer 4, it thus plays a role in hiding the characters.

[0030] Reference Figure 1, on the side of the outer light-transmitting plastic plate 2 away from the inner plastic plate 6, a texture area 11 and a transparent area 12 are respectively provided. The transparent area 12 corresponds to the lighting area 8, so that the light of the illumination light source passes through the transparent area 12 with high light transmittance. The texture area 11 corresponds to the character area 7, thereby increasing tactile recognition.

[0031] Reference Figure 1 , after the printing of the smoky gray ink in the conventional printing scheme is completed, it is prone to irregular flow after being baked by the high-temperature plastic particle flow during the injection molding process, resulting in the offset of the character color coordinates and large fluctuations. In view of the problem of color coordinate offset generated after the injection molding of the smoky gray ink, a high-transparency and high-temperature-resistant transparent ink layer 5 is printed after the printing of all the smoky gray ink is completed, reducing the impact of high temperature on the smoky gray ink layer 4, and further reducing its softening flow. Through the innovation of the above various methods, the color coordinates of the characters can finally meet the fluctuation of ±1%.

[0032] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
