Description

Technical Field

[0001] The invention belongs to the technical field of glass cover plate preparation, and relates to a semi-transparent glass cover plate, in particular to a semi-transparent glass cover plate with uniform brightness. Background Art

[0002] The existing printing ink for glass cover is usually used to uniformly print the entire semi-transparent key part of the glass cover, and the color transmittance of the printed part is uniform. Under the illumination of light, due to the different light divergence effects, the semi-transparent glass cover with a small area has no effect under the illumination of a single light. However, for semi-transparent glass covers with large areas and large length and width, when multiple light sources are required for illumination and display, due to different light positions and light brightness, the brightness of the semi-transparent glass cover will be uneven, with high brightness in the part directly above the light source and low brightness in the part away from the light source. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a semi-transparent glass cover plate with uniform brightness, which improves the problem of uneven brightness of the semi-transparent key part of the large area of ​​the glass cover plate due to illumination by multiple light sources, so that the strong light area and the weak light area have consistent display brightness under different light source effects.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] A semi-transparent glass cover plate with uniform brightness, wherein the semi-transparent part of the glass cover plate is divided into a plurality of different brightness areas according to the distribution of light sources and the illumination intensity, wherein the plurality of different brightness areas specifically include: a strong light area, a transition area and a weak light area, wherein the strong light area is connected to the weak light area through the transition area, a first ink layer is silk-screened on the strong light area, a second ink layer is silk-screened on the transition area, a plurality of first type ink dots are distributed on both the first ink layer and the second ink layer, and the density of the first type ink dots on the first ink layer is greater than the density of the first type ink dots on the second ink layer.

[0006] Furthermore, the density of the first type of ink dots on the second ink layer gradually decreases from the strong light area to the weak light area.

[0007] Furthermore, the first type of ink dots are dots with a diameter of 0.3 mm, the gap between adjacent first type of ink dots on the first ink layer is 0.01 mm, and the gap between adjacent first type of ink dots on the second ink layer increases from 0.01 mm to 0.5 mm along the strong light area toward the weak light area.

[0008] Furthermore, a plurality of second type ink dots are distributed on the first ink layer. The second type ink dots are distributed at the center between four adjacent first type ink dots. The gap between the second type ink dots and the four first type ink dots is 0.01 mm.

[0009] Furthermore, the first ink layer is formed by screen-printing a layer of ink on the glass cover plate by a prefabricated first screen, and the first type of ink dots and the second type of ink dots on the first ink layer are both ink-covered areas. The second ink layer is formed by screen-printing a layer of ink on the glass cover plate by a prefabricated second screen, and the first type of ink dots on the second ink layer are ink-covered areas.

[0010] Furthermore, both the first screen and the second screen are made of pre-printed or drawn dot films, and the dot films are designed according to different brightness areas so that the dots in the part of the film corresponding to the strong light area are dense, the dots in the part corresponding to the transition area are gradually sparse, and the dots in the part corresponding to the weak light area disappear completely.

[0011] Furthermore, the first type of ink dots include a center point and a plurality of concentrically arranged annular ink areas, the radii of the plurality of annular ink areas are successively increased and arranged at intervals, and the ink on the first type of ink dots is all covered in the center point and the plurality of annular ink areas.

[0012] Furthermore, the center point radius, the width of multiple annular ink areas and the gaps between adjacent annular ink areas on the same first type ink dot are the same, and all correspond to the gaps between adjacent first type ink dots in the area where the first type ink dots are located.

[0013] Beneficial effects of the present invention: the semi-transparent glass cover plate with uniform brightness provided by the present invention is divided into a strong light area, a transition area and a weak light area according to the distribution of light sources and the illumination intensity, and the corresponding dot film is printed or drawn according to the different brightness areas, so that the dots of the film corresponding to the strong light area are dense, the dots of the film corresponding to the transition area are gradually sparse, and the dots of the film corresponding to the weak light area disappear completely, and finally a screen is made by the dot film, and a layer of ink is silk-screened on the glass cover plate, so that the brightness of the strong light area is blocked by the dense ink dots, and the density of the ink dots in the transition area gradually decreases from the strong light area to the weak light area, and there is no ink dot blocking on the weak light area, which does not affect the brightness, so that the light display effect of the semi-transparent glass cover plate is consistent, and the problem of uneven brightness of the semi-transparent key part of the large area of ​​the glass cover plate due to the illumination of multiple light sources is improved, so that the brightness displayed in the strong light area and the weak light area is consistent under different light source effects.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, the present invention provides a semi-transparent glass cover plate with uniform brightness, and the semi-transparent part of the glass cover plate is divided into a plurality of different brightness areas according to the distribution and illumination intensity of the light source 1, and the plurality of different brightness areas specifically include: a strong light area 2 with an illumination intensity greater than a first preset threshold, a transition area 3 with an illumination intensity between the first preset threshold and a second preset threshold, and a weak light area 4 with an illumination intensity less than the second preset threshold. The strong light area 2, the transition area 3, and the weak light area 4 are distributed in an annular circle along the diffusion direction of the light from the light source 1 on the semi-transparent glass cover plate, the strong light area 2 is at the center position directly illuminated by the light source 1, the transition area 3 surrounds the strong light area 2, the weak light area 4 surrounds the transition area 3, and the strong light area 2 is connected to the weak light area 4 through the transition area 3.

[0020] like Figure 2 As shown, a first ink layer is silk-screened on the strong light area 2, a second ink layer is silk-screened on the transition area 3, and there is no ink layer on the weak light area 4. A plurality of first type ink dots 5 are distributed on both the first ink layer and the second ink layer. The density of the first type ink dots 5 on the first ink layer is greater than that of the first type ink dots 5 on the second ink layer. The density of the first type ink dots 5 on the second ink layer gradually decreases from the strong light area 2 toward the weak light area 4, so that the brightness of the light in the strong light area 2 is blocked by the dense first type ink dots 5. The light blocking effect of the first type ink dots 5 on the transition area 3 gradually weakens from the strong light area 2 to the weak light area 4. There is no ink dot blocking on the weak light area 4, which does not affect the brightness, so that the light display effect of the semi-transparent glass cover is consistent and the brightness unevenness is improved.

[0021] Specifically, the first type ink dots 5 are dots with a diameter of 0.3 mm, the gap between adjacent first type ink dots 5 on the first ink layer is 0.01 mm, and the gap between adjacent first type ink dots 5 on the second ink layer increases from 0.01 mm to 0.5 mm along the strong light area 2 toward the weak light area 4.

[0022] Since the diameter of the first type ink dot 5 is much larger than the gap between adjacent first type ink dots 5, when the four first type ink dots 5 form a matrix, the gap between two adjacent first type ink dots 5 in the diagonal direction is much larger than the gap between two adjacent first type ink dots 5 in the horizontal / vertical direction, resulting in bright spots between the four first type ink dots 5, affecting the uniformity of the brightness of the semi-transparent glass cover. Therefore, a plurality of second type ink dots 6 are also distributed on the first ink layer, such as Figure 3 As shown, the second type ink dots 6 are distributed at the center position between four adjacent first type ink dots 5, blocking the bright spots appearing between the four first type ink dots 5, further improving the uniformity of the brightness of the semi-transparent glass cover. Specifically, the gaps between the second type ink dots 6 and the four first type ink dots 5 are all 0.01 mm.

[0023] The first ink layer is a layer of ink printed on the glass cover plate by a prefabricated first screen, and the first type of ink dots 5 and the second type of ink dots 6 on the first ink layer are all covered by ink. The second ink layer is a layer of ink printed on the glass cover plate by a prefabricated second screen, and the first type of ink dots 5 on the second ink layer are all covered by ink. The first screen and the second screen are both made of pre-printed or drawn dot films, and the dot films are designed according to different brightness areas, so that the dots of the film corresponding to the strong light area 2 are dense, the dots corresponding to the transition area 3 are gradually sparse, and the dots corresponding to the weak light area 4 are completely gone.

[0024] like Figure 4 As shown, the first type of ink dot 5 includes a concentrically arranged center point 51 and a plurality of annular ink areas 52, the radius of the plurality of annular ink areas 52 increases in sequence and is arranged at intervals, and the ink on the first type of ink dot 5 is all covered in the center point 51 and the plurality of annular ink areas 52, so that the first type of ink dot 5 can evenly transmit light while shielding light, further improving the uniformity of the brightness of the semi-transparent glass cover plate, and avoiding the generation of black spots in the strong light area 2 and the transition area 3 when the illumination intensity of the light source 1 is insufficient. Specifically, the radius of the center point 51, the width of the plurality of annular ink areas 52, and the gap between adjacent annular ink areas 52 on the same first type of ink dot 5 are the same, and all correspond to the gap between adjacent first type of ink dots 5 in the area where the first type of ink dot 5 is located.

[0025] The semi-transparent glass cover plate with uniform brightness provided by the present invention is divided into a strong light area, a transition area and a weak light area according to the distribution and illumination intensity of the light source, and the corresponding dot film is printed or drawn according to the different brightness areas, so that the dots of the film corresponding to the strong light area are dense, the dots of the film corresponding to the transition area are gradually sparse, and the dots of the film corresponding to the weak light area disappear completely. Finally, a screen is made by the dot film, and a layer of ink is silk-screened on the glass cover plate, so that the brightness of the strong light area is blocked by the dense ink dots, and the density of the ink dots in the transition area gradually decreases from the strong light area to the weak light area. There is no ink dot blocking on the weak light area, and the brightness is not affected, so that the light display effect of the semi-transparent glass cover plate is consistent, and the problem of uneven brightness of the semi-transparent key part of the large-area semi-transparent key part of the glass cover plate due to the illumination of multiple light sources is improved, so that the brightness displayed in the strong light area and the weak light area is consistent under different light source effects.
