In the conventional semi-permeable hole production process, as shown in fig. 1 and 2, a screen printing semi-permeable ink is adopted, a shading ink 200 is firstly manufactured on a glass cover plate 100, then a hollowed-out area 201 is manufactured on the shading ink 200, and finally a semi-permeable ink 300 is manufactured in the hollowed-out area 201. In the process, the semi-permeable holes made by the silk-screen process have low light transmission uniformity in function, the fluctuation range of the transmittance is wide, the uniformity and the transmittance of the semi-permeable holes can be fluctuated, and the material cost and the labor cost are too high.

Chinese patent document CN201420144286.6 discloses a panel with hidden light holes, comprising:

a transparent substrate having a first surface and a second surface opposite to the first surface, wherein the first surface is a window surface;

a main body black ink layer arranged on the edge of the second surface, wherein the area surrounded by the main body black ink layer on the second surface is a window area, and a through hole is arranged on the main body black ink layer; a cap black ink layer covering the main body black ink layer, the cap black ink layer exposing the through hole; an IR transparent ink layer covering the via area; and a semi-transparent ink layer covering the IR transparent ink layer, wherein the semi-transparent ink layer completely covers the through holes to form hidden light holes. The transmittance of the IR transparent ink layer is 5% -10%. The semi-permeable ink layer is a white ink layer and the thickness of the white ink layer is less than 6 microns. The coverage area of the IR transparent ink layer is equal to the open area of the through hole. The coverage area of the white ink layer is larger than the open area of the through hole. The transparent substrate is a glass substrate or a resin substrate. The semi-transparent ink layer is a white ink layer, a light gray ink layer or a beige ink layer. The hidden light holes are indication lamp holes, strong light lamp holes, key patterns or logo patterns.

Obviously, the patent is suitable for shading through the semi-transparent ink layer, and is further shaded through the IR transparent ink layer, so that the light is uniform and soft, and the problem of high manufacturing process cost of the semi-transparent hole of the conventional touch screen cannot be solved.

The thickness of the semi-transparent ink layer is 2-20 mu m, and the transmittance of visible light passing through the semi-transparent ink layer and through the hidden light holes is 1% -7%. The area of the semi-permeable ink layer is larger than that of the hidden light-transmitting hole. The hidden light holes are indication lamp holes, strong light lamp holes, key patterns or identification patterns. And at least one of transparent holes, through holes and infrared induction holes are also arranged on the cover plate and the black frame layer. The black frame layer comprises a first ink layer and a second ink layer, wherein the first ink layer is arranged between the cover plate and the second ink layer, a gap is formed in the position, where the hidden light hole is formed, on the first ink layer, and the second ink layer covers the gap.
