[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.
[0019] Figure 1 The utility model provides a structural schematic diagram of a cover plate structure for solving the problem of ink frame printing.
[0020] Description of the drawings: 10, cover body; 20, first layer of ink; 30, second layer of ink; 31, groove; 40, character mark alignment line area; 50, anti-glare coating. DETAILED DESCRIPTION
[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0022] A cover plate structure for solving ink frame printing, referring to Figure 1 , including a cover body 10, a first layer of ink 20 and a second layer of ink 30 are sequentially arranged on one side surface of the cover body 10 from top to bottom. The first layer of ink 20 is screen-printed on one side surface of the cover body 10, and the second layer of ink 30 is screen-printed on the first layer of ink 20, and the first layer of ink 20 and the second layer of ink 30 are sequentially stacked.
[0023] Reference Figure 1The color of the first layer of ink 20 is black, white or color. The first layer of ink 20 is used to absorb light when the cover body 10 and the display module are installed, thereby preventing the light from being emitted from the side of the cover body 10 and preventing light leakage around the edges of the cover body 10.
[0024] Further, refer to Figure 1 The thickness of the first layer of ink 20 is 5um-8um. The thickness of the first layer of ink 20 determines the degree of light shielding and enables the second layer of ink 30 to adhere to the first layer of ink 20.
[0025] Reference Figure 1 The second layer of ink 30 is screen-printed on the first layer of ink 20. The second layer of ink 30 is ultra-black ink. The ultra-black ink has ultra-low reflectivity and is completely opaque, and can completely block the color difference caused by light transmission and light reflection.
[0026] Reference Figure 1 , the thickness of the second layer of ink 30 is 5um-7um.
[0027] Reference Figure 1 A character mark alignment line area 40 is provided on the first layer of ink 20. The character mark alignment line area 40 is used to identify the model and pattern of the cover body 10. The character mark alignment line area 40 is used to facilitate position determination and production tracking.
[0028] Reference Figure 1 , the character mark alignment line area 40 is screen-printed on the first layer of ink 20, the character mark alignment line area 40 is screen-printed on the first layer of ink 20 through ink, and the second layer of ink 30 is hollowed out relative to the character mark alignment line area 40. A groove 31 is provided at the second layer of ink 30 relative to the character mark alignment line area 40, so that the second layer of ink 30 is not screen-printed at the position of the character mark alignment line area 40. A step difference is formed between the second layer of ink 30 and the first layer of ink 20, and the character mark alignment line area 40 is located in the groove 31, thereby reducing the screen printing level and replacing the original screen-printed convex character mark alignment line area 40. The second layer of ink 30 is ultra-black ink, which can completely block the color difference caused by light transmission and reflection, avoid the occurrence of frame printing, and does not affect the optical parameters of the first layer of ink 20, nor does it affect the surface adhesion performance of the second layer of ink 30.
[0029] Further, refer to Figure 1 The thickness of the character mark in the position line area 40 is 3um-6um, and the thickness of the character mark in the position line area 40 is less than the thickness of the second layer of ink 30.
[0030] Reference Figure 1The cover body 10 includes a display area and a non-display area. When the cover body 10 is assembled with the display module, the display area is the area for displaying content, and the non-display area is the frame area. The first layer of ink 20, the second layer of ink 30 and the character mark alignment line area 40 are all located in the non-display area. The first layer of ink 20, the second layer of ink 30 and the character mark alignment line area 40 are arranged around the four peripheries of the display area.
[0031] Further, refer to Figure 1 The surface of the cover body 10 is provided with an anti-glare coating 50 so that the cover body 10 has an anti-glare effect.
[0032] Reference Figure 1 , the thickness of the anti-glare coating 50 is 100um-125um.
[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
