Description

Technical Field

[0001] The utility model relates to a touch screen cover plate, in particular to a cover plate with a gradient pattern and a touch screen. Background Art

[0002] With the rapid development of intelligent cars and new energy vehicles, more and more young consumers tend to choose intelligent cars or new energy vehicles when purchasing vehicles. However, at present, the display effects of in-vehicle central control screens or instrument panels are single and can no longer meet the needs of young consumers who pursue individuality.

[0003] A gradient pattern refers to a color of an object that changes from bright to dark, or from deep to light, or slowly transitions from one color to another, full of infinite changes and mysterious and romantic atmosphere. At present, there is a gradient display effect on in-vehicle central control or instrument display screens, and the displayed pattern changes from dark to bright, which is very dynamic and cool.

[0004] For example, the Chinese patent with the application number CN202121745201.6 discloses a cover plate with a gradient display effect. A black ink layer is provided on one side of the cover plate. The black ink layer is composed of a pattern area and a shielding area. A gradient pattern is provided in the pattern area. The gradient pattern is composed of a plurality of transparent small holes provided on the ink layer. The small holes are arranged in a gradient array in the pattern area to form a gradient pattern. The gradient mode of the gradient array follows the gradient effect of the gradient pattern. The display pattern on this cover plate is composed of small holes, and the small holes are arranged in a gradient array according to the requirements of the pattern gradient, so that when the pattern is illuminated by backlight, the pattern display shows a gradient effect.

[0005] However, the cover plate in the above patent needs to be used in conjunction with backlight to illuminate the gradient pattern with backlight, resulting in relatively high power consumption. Content of the Utility Model

[0006] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides a cover plate with a gradient pattern, which has relatively low power consumption.

[0007] The utility model also provides a touch screen, including the above cover plate.

[0015] Furthermore, the light shielding layer has a first gradient region and a second gradient region. The light reflecting gradient pattern formed by the light reflecting holes is located in the first gradient region, and the light transmitting gradient pattern formed by the light transmitting holes is located in the second gradient region.

[0016] Furthermore, the light shielding layer has a mixed gradient region. The light reflecting gradient pattern formed by the light reflecting holes and the light transmitting gradient pattern formed by the light transmitting holes are both located in the mixed gradient region, wherein the light reflecting holes and the light transmitting holes are alternately distributed in sequence along a first direction.

[0017] Furthermore, the light shielding layer has a mixed gradient region. The light reflecting gradient pattern formed by the light reflecting holes and the light transmitting gradient pattern formed by the light transmitting holes are both located in the mixed gradient region, wherein the light reflecting holes and the light transmitting holes are alternately distributed in sequence along a first direction and a second direction perpendicular to each other respectively.

[0018] Furthermore, the cover plate further includes a backlight assembly. The backlight assembly is disposed on a side of the light shielding layer away from the cover plate base layer and at least covers the light transmitting holes.

[0019] Furthermore, the light shielding layer is further provided with photosensitive holes; the cover plate further includes photosensitive elements. The photosensitive elements are disposed on a side of the light shielding layer away from the cover plate base layer and cover the photosensitive holes.

[0030] Embodiment 1

[0031] As Figures 1-4 shown, a cover plate with a gradient pattern includes:

[0032] A cover plate base layer 11;

[0033] A light-shielding layer 12, disposed on one side of the cover plate base layer 11, includes a reflective gradient pattern composed of a plurality of reflective holes 121 with gradually changing aperture or pitch, and a transmissive gradient pattern composed of a plurality of transmissive holes 122 with gradually changing aperture or pitch.

[0034] In the cover plate of the present utility model, a set of reflective holes 121 and a set of transmissive holes 122 are made in the light-shielding layer 12. The reflective gradient pattern formed by the reflective holes 121 is displayed by reflecting ambient light, while the transmissive gradient pattern formed by the transmissive holes 122 is displayed by transmitting backlight. When the ambient light brightness is relatively high, the backlight assembly can be turned off and only the reflective gradient pattern can be displayed by reflecting ambient light through the reflective holes 121. When the ambient light brightness is relatively low, the backlight assembly can be turned on and only the transmissive gradient pattern can be displayed by transmitting backlight through the transmissive holes 122, so as to achieve the purpose of reducing power consumption.

[0035] The light-shielding layer 12 can be made of any material with a light-shielding effect and any color, such as common black ink, white ink, blue ink, etc., or an oxide metal coating with a relatively low reflectivity, or a polymer coating, etc.

[0036] The reflective holes 121 and transmissive holes 122 can be, but are not limited to, circular holes, elliptical holes, rectangular holes, etc.

[0037] The reflective hole 121 includes a first through hole 123 and a reflective material 13 filled in the first through hole 123, and the light-transmitting hole 122 includes a second through hole 124 and a light-transmitting material 14 filled in the second through hole 124.

[0038] Among them, the first through hole 123 and the second through hole 124 can be formed by, but are not limited to, etching the light-shielding layer 12 with a laser or an etching solution to locally remove the light-shielding layer 12; the reflective material 13 can be, but is not limited to, a metal material, and is filled in the first through hole 123 by means of magnetron sputtering, chemical vapor deposition or vacuum evaporation; the light-transmitting material 14 can be, but is not limited to, semi-transparent ink, and is filled in the second through hole 124 by means of screen printing.

[0039] In this embodiment, the aperture of the reflective hole and the light-transmitting hole gradually changes between 0.015 - 0.100 mm, or the distance between the reflective hole and the light-transmitting hole gradually changes between 0.25 - 0.40 mm.

[0040] The aperture or the distance of the reflective hole 121 gradually changes along a first direction or a second direction perpendicular to each other. The larger the aperture of the reflective hole 121, the greater the light transmittance of the reflective gradient pattern; the smaller the aperture of the reflective hole 121, the smaller the light transmittance of the reflective gradient pattern. Similarly, the larger the distance between the reflective holes 121, the smaller the light transmittance of the reflective gradient pattern; the smaller the distance between the reflective holes 121, the greater the light transmittance of the reflective gradient pattern.

[0041] In the reflective gradient pattern, the aperture of the reflective hole 121 can gradually change from a small aperture to a large aperture, or from a large aperture to a small aperture. It can also first gradually change from a small aperture to a large aperture, and then from a large aperture to a small aperture, or first gradually change from a large aperture to a small aperture, and then from a small aperture to a large aperture.

[0042] Alternatively, in the reflective gradient pattern, the distance between the reflective holes 121 can gradually change from a small distance to a large distance, or from a large distance to a small distance. It can also first gradually change from a small distance to a large distance, and then from a large distance to a small distance, or first gradually change from a large distance to a small distance, and then from a small distance to a large distance.

[0043] Similarly, the aperture diameter or pitch of the light-transmitting holes 122 gradually changes along a first direction or a second direction perpendicular to each other. The larger the aperture diameter of the light-transmitting holes 122, the greater the light transmittance of the light-transmitting gradient pattern, and the smaller the aperture diameter of the light-transmitting holes 122, the smaller the light transmittance of the light-transmitting gradient pattern; similarly, the larger the pitch of the light-transmitting holes 122, the smaller the light transmittance of the light-transmitting gradient pattern, and the smaller the pitch of the light-transmitting holes 122, the greater the light transmittance of the light-transmitting gradient pattern.

[0044] In the light-transmitting gradient pattern, the aperture diameter of the light-transmitting holes 122 can gradually change from a small aperture diameter to a large aperture diameter, or can gradually change from a large aperture diameter to a small aperture diameter, or can first gradually change from a small aperture diameter to a large aperture diameter, and then gradually change from a large aperture diameter to a small aperture diameter, or can first gradually change from a large aperture diameter to a small aperture diameter, and then gradually change from a small aperture diameter to a large aperture diameter.

[0045] Similarly, in the light-transmitting gradient pattern, the pitch of the light-transmitting holes 122 can gradually change from a small pitch to a large pitch, or can gradually change from a large pitch to a small pitch, or can first gradually change from a small pitch to a large pitch, and then gradually change from a large pitch to a small pitch, or can first gradually change from a large pitch to a small pitch, and then gradually change from a small pitch to a large pitch.

[0046] In a specific implementation manner, as Figure 1 shown, the light-reflecting holes 121 and the light-transmitting holes 122 are respectively distributed in different gradient regions of the light-shielding layer 12.

[0047] For example, the light-shielding layer 12 has a first gradient region 10a and a second gradient region 10b. The light-reflecting gradient pattern formed by the light-reflecting holes 121 is located in the first gradient region 10a, and the light-transmitting gradient pattern formed by the light-transmitting holes 122 is located in the second gradient region 10b.

[0048] In another specific implementation manner, as Figure 3 shown, the light-reflecting holes 121 and the light-transmitting holes 122 are mixedly distributed in the same gradient region of the light-shielding layer 12.

[0049] For example, the light-shielding layer 12 has a mixed gradient region 10c. The light-reflecting gradient pattern formed by the light-reflecting holes 121 and the light-transmitting gradient pattern formed by the light-transmitting holes 122 are both located in the mixed gradient region 10c, wherein the light-reflecting holes 121 and the light-transmitting holes 122 are alternately distributed in sequence along the first direction, or the light-reflecting holes 121 and the light-transmitting holes 122 are alternately distributed in sequence along the first direction and the second direction perpendicular to each other respectively.

[0050] Preferably, the cover plate base layer 11 is tempered glass.

[0051] As Figure 2and 4 As shown in 4 , the cover plate further includes a backlight assembly 15, which is disposed on a side of the light-shielding layer 12 away from the cover plate base layer 11 and at least covers the light-transmitting holes 122.

[0052] As Figure 2 shown in Figure 2 , when the light-reflecting holes 121 and the light-transmitting holes 122 are respectively distributed in different gradient regions of the light-shielding layer 12, the backlight assembly 15 only covers the light-transmitting gradient pattern formed by the light-transmitting holes 122. As Figure 4 shown in Figure 4 , when the light-reflecting holes 121 and the light-transmitting holes 122 are mixedly distributed in the same gradient region of the light-shielding layer 12, the backlight assembly 15 simultaneously covers the light-reflecting gradient pattern formed by the light-reflecting holes 121 and the light-transmitting gradient pattern formed by the light-transmitting holes 122.

[0053] Preferably, as Figure 1 and 3 shown in 3 , the light-shielding layer 12 is further provided with photosensitive holes 125; the cover plate further includes a photosensitive element 16, which is disposed on a side of the light-shielding layer 12 away from the cover plate base layer 11 and covers the photosensitive holes 125.

[0054] The photosensitive element 16 may be, but is not limited to, a photoelectric sensor, which is used to sense the brightness of ambient light through the photosensitive holes 125. When the brightness of the ambient light reaches or is greater than a preset brightness, the backlight assembly 15 is controlled to be turned off. When the brightness of the ambient light is less than the preset brightness, the backlight assembly 15 is controlled to be lit.

[0055] The cover plate further includes a touch area 10d, which is used to set a touch function layer; the light-shielding layer 12 is arranged to avoid the touch area 10d.

[0056] Embodiment 2

[0057] A touch screen includes a touch function layer and the cover plate according to Embodiment 1. The cover plate has a touch area 10d, and the touch function layer is arranged in the touch area 10d of the cover plate.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention and are not intended to limit them. Although the embodiments of the present invention have been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the embodiments of the present invention can still be modified or equivalently replaced, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
