Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display modules, in particular to a white cover plate structure with hidden semi-transparent holes. Background Art
[0002] Liquid crystal display devices are widely used in various information, communication and consumer electronic products. The liquid crystal display module is mainly composed of a liquid crystal display screen and a backlight module. The surface of the liquid crystal display screen is usually provided with a cover plate for protection. The cover plate provides hardness for the liquid crystal display screen. The backlight module provides a light source for the liquid crystal display screen. The light source enters the liquid crystal display screen and displays various colors. At present, most consumer electronic products on the market have a black appearance, and of course there are also some products with a white appearance. Products with a white appearance are provided with buttons, indicator lights and other designs. For the sake of beauty, it is usually required that the product only shows the appearance of the buttons or indicator lights when the lights are on. When the lights are not on, it is completely invisible in an integrated white state, also called a hidden white semi-transparent design. It is more difficult to hide the buttons of products with a white appearance when the lights are not on, unlike black, which can achieve a good hiding effect by simply adding a layer of semi-transparent black ink.
[0003] In the prior art, a cover plate with a white appearance usually needs to be printed with more than three layers of white ink on the cover plate body, and only one additional layer is printed in the area where the keys are set. When the light is not on, the white color difference between the key area and other areas of the cover plate is large, and the effect of integrated white cannot be achieved. Utility Model Content

[0020] Description of the drawings: 10. Cover plate body; 20. Semi-transparent key area; 21. Semi-transparent hole; 30. First layer of covering ink; 40. Second layer of covering ink; 50. Third layer of covering ink; 60. Cover bottom ink; 61. Opening. 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 white cover structure with hidden semi-permeable holes, referring to Figure 1 The cover body 10 includes a semi-transparent key area 20, a semi-transparent hole 21 is provided on the semi-transparent key area 20, and the coverage rate of the semi-transparent hole 21 in the semi-transparent key area 20 is 1%-100%. The light transmittance of the semi-transparent key area 20 is adjusted by controlling the distribution density of the semi-transparent holes 21 and the aperture of the semi-transparent holes 21.
[0023] Reference Figure 1 A covering ink structure for shading is provided on the cover body 10, and the covering ink structure covers the entire range of the cover body 10. The semi-transparent key area 20 on the cover body 10 and the area of the cover body 10 other than the semi-transparent key area 20 are covered with the covering ink structure. The covering ink structure includes a first layer of covering ink 30, a second layer of covering ink 40 and a third layer of covering ink 50, and the first layer of covering ink 30, the second layer of covering ink 40 and the third layer of covering ink 50 are stacked in sequence.
[0024] Reference Figure 1 The first layer of covering ink 30 is disposed on the cover body 10 , and the first layer of covering ink 30 covers the semi-transparent key area 20 and the area of the cover body 10 outside the semi-transparent key area 20 , that is, the first layer of covering ink 30 covers the entire surface of the cover body 10 , and the first layer of covering ink 30 covers the position of the semi-transparent hole 21 .
[0025] Reference Figure 1 The first layer of covering ink 30 is white ink, and the thickness of the first layer of covering ink 30 is 2um-4um.
[0026] Reference Figure 1 The second layer of covering ink 40 is screen printed on the first layer of covering ink 30, and the coverage of the second layer of covering ink 40 is consistent with the coverage of the first layer of covering ink 30. The second layer of covering ink 40 is screen printed on the side of the first layer of covering ink 30 away from the cover body 10. The second layer of covering ink 40 covers the position of the semi-transparent key area 20.
[0027] Reference Figure 1The second layer of covering ink 40 is white ink, and the thickness of the second layer of covering ink 40 is 5um-7um.
[0028] Reference Figure 1 The third layer of covering ink 50 is screen-printed on the second layer of covering ink 40 , the coverage of the third layer of covering ink 50 is consistent with the coverage of the second layer of covering ink 40 , the third layer of covering ink 50 covers the entire surface of the cover body 10 , and the third layer of covering ink 50 covers the position of the semi-transparent key area 20 .
[0029] Reference Figure 1 The third layer of covering ink 50 is white ink, and the thickness of the third layer of covering ink 50 is 5um-7um.
[0030] Reference Figure 1 The semi-transparent hole 21 of the semi-transparent key area 20 has three layers of white ink, namely, a first layer of covering ink 30, a second layer of covering ink 40 and a third layer of covering ink 50, which are stacked in sequence. The positions of the first layer of covering ink 30, the second layer of covering ink 40 and the third layer of covering ink 50 relative to the semi-transparent key area 20 are not hollowed out. Since the white ink has strong light transmittance, under the stacking of three layers of white ink, the position of the semi-transparent hole 21 still has a transmittance of 1%, so that the light can pass through so that the user can see the pattern of the semi-transparent key area 20 clearly. When the light is not on, the entire cover body 10 appears white, and the white uniformity is good, presenting a one-piece white effect, avoiding obvious color differences in the semi-transparent key area 20 of the cover body 10 and other areas of the cover body 10, thereby improving the ornamental value of the cover body 10.
[0031] Reference Figure 1 The third layer of covering ink 50 is provided with a bottom covering ink 60, which is used for shielding light to prevent light from leaking from the four side edges of the cover body 10. The bottom covering ink 60 is screen-printed on the side of the third layer of covering ink 50 away from the second layer of covering ink 40, and the bottom covering ink 60 is provided with an opening 61 relative to the semi-transparent key area 20. The bottom covering ink 60 is screen-printed on the area of the cover body 10 other than the semi-transparent key area 20.
[0032] Reference Figure 1 The bottom cover ink 60 is black ink, and an opening 61 is formed in the bottom cover ink 60 relative to the semi-transparent key area 20 to prevent the position of the semi-transparent key area 20 from being transparent and affecting the appearance of the semi-transparent key area 20 .
[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.
