and c, frosting the part to be frosted on the first surface 111 of the glass substrate 110, and carrying out surface protection on the rest part of the glass substrate 110 before frosting.
In one embodiment, the glass substrate 110 having a size meeting the requirements of the housing 100 is prepared, cleaned and dried. A photosensitive material is sprayed on the first surface 111 of the glass substrate 110 to form a photosensitive layer. It is understood that the photosensitive material is photoresist. Preparing the photomask with the texture gradient effect, wherein the texture gradient effect of the photomask can be determined according to the actual requirement of a product. For example, the thickness of the texture and the size of the holes at different positions of the photomask can be determined according to actual requirements, so that the texture gradient effect is formed. It is understood that the preparation of the mask may be performed simultaneously with step a, may precede step a, or may be performed after step a, and is not limited herein. The photomask is placed on the side of the first surface 111 of the glass substrate 110, a UV light source is disposed on the side of the photomask opposite to the first surface 111, the first surface 111 is exposed by using the UV light source, and the UV light source irradiates the photosensitive layer through the texture on the photomask to produce the texture on the photosensitive layer. It is understood that the photosensitive layer is chemically changed by the UV light source, but its physical form is not changed, so that the texture generated on the photosensitive layer is not visible to the naked eye. The exposed glass substrate 110 is developed, i.e., the glass substrate 110 is placed in an alkaline solution, and a gradient texture layer 140 having the same or complementary texture as the photomask is formed on the photosensitive layer.
In an embodiment, the portion to be frosted of the first surface 111 is determined according to a requirement, and the portion to be frosted may be a portion of the gradient texture layer 140, or a portion of the first surface 111 that is complementary to the gradient texture layer 140, or the first surface 111, or a portion of the gradient texture layer 140 and a portion of a position that is complementary to the gradient texture layer 140, which is not specifically limited herein. It can be understood that the gradient texture layer 140 formed by exposure and development is a three-dimensional texture, and frosting only affects the roughness and transmittance of the gradient texture layer 140 and does not change the outline of the gradient texture layer 140. The remaining portion of the glass substrate 110, i.e., the portion not requiring frosting, is surface-protected and may be coated with tape or ink to prevent it from being etched by the frosting solution. After the portion of the first surface 111 to be frosted is frosted, the surface roughness is increased, the transmittance is decreased, and the first surface 111 realizes a diversified appearance effect together with the gradient texture layer 140.
As shown in fig. 7, in an embodiment, the frosted portion of the first surface 111 is polished by using a polishing liquid, so that the frosted portion has a frosted gradual effect. And (3) preparing a polishing solution, clamping the second end of the glass substrate 110 by using a numerical control device with a glass clamp, and vertically or obliquely putting the glass substrate 110 into the polishing solution at a constant speed from the first end at a first speed until the glass substrate 110 is completely soaked. It is understood that the first end and the second end of the glass substrate 110 are disposed opposite to each other, and the first end of the glass substrate 110 is the end requiring the smaller haze and the second end is the end requiring the larger haze. The polishing solution comprises hydrofluoric acid with the concentration of 1-20%, and other acids with the concentration of 1-20%, such as sulfuric acid, hydrochloric acid, nitric acid, etc. The glass substrate 110 can be vertically or slightly tilted and preferably vertically placed into the polishing solution, and the end of the glass substrate 110 requiring less haze, i.e., the first end, is preferably uniformly placed into the polishing solution at a first speed, so that the polishing solution has enough time to polish the end requiring less haze, and the haze and the roughness of the end are reduced. One end, namely the second end, needing larger haze is placed into the polishing solution at a first speed at a constant speed, so that the polishing solution has shorter time for polishing the side, and the haze and the roughness of the side are larger. It can be understood that the speed of placing the glass substrate 110 into the polishing solution can be set according to the difference between the haze values of the two ends of the housing 100 to be prepared, and when the difference between the haze values of the two ends of the housing 100 to be prepared is larger, the speed is set to be smaller so as to increase the time difference between the two ends of the glass substrate 110 in the polishing solution to increase the difference between the haze values of the two ends of the glass substrate 110; when the difference in haze between the two ends of the housing 100 to be prepared is small, a large speed is set to reduce the time difference between the two ends of the glass substrate 110 in the polishing liquid to reduce the difference in haze between the two ends of the glass substrate 110. It is understood that the set speed is at or near a constant speed so that the haze of the glass substrate 110 exhibits a gradual effect. If the set speed is changed, the haze jump effect may occur.
And clamping the second end of the glass substrate 110 by using a numerical control device with a glass clamp, and lifting the glass substrate 110 from the polishing solution at a constant speed according to a second speed from the second end. The glass substrate 110 is lifted out of the polishing solution from one end, namely the second end, which enters the polishing solution, and finally is separated from the polishing solution from one end, namely the first end, which enters the polishing solution, so that a polished time difference exists between the two ends, the effect of differentiation of the haze at the two ends is achieved, and the condition of gradual change of the haze at the two ends is determined by the set speed.
The adhesive tape or ink for surface protection of the glass substrate 110 is removed, the glass substrate 110 is cleaned and dried, and a glass strengthening process is performed on the glass substrate 110 to increase the strength of the glass substrate 110. In one embodiment, the glass substrate 110 is processed by an OC0 process (resin solution spraying and anti-breaking process) to provide the glass substrate 110 with anti-breaking functions. In another embodiment, the glass substrate 110 may be processed by other glass strengthening processes.

Together, film 123, optically textured layer 124, optically coated layer 125, and first ink layer 126 form decorative layer 120.
As shown in fig. 4, in one embodiment, the film 123 is bonded to the second surface 112 by an OCA glue, and the OCA glue forms an OCA glue layer 122. The OCA glue layer 122 is a transparent layer, and does not affect the display effect of the optical texture layer 124, the optical coating layer 125 and the first ink layer 126.
As shown in fig. 4, in an embodiment, a second ink layer 121 is disposed on the second surface 112, and the second ink layer 121 is in a pattern shape, and can print a LOGO or other patterns or characters capable of displaying characteristics of a product. Second ink layer 121 is located between OCA glue layer 122 and second surface 112. It is understood that in this embodiment, decorative layer 120 includes second ink layer 121, OCA glue layer 122, film 123, optical texture layer 124, optical coating layer 125, and first ink layer 126, which are disposed in this order.
As shown in fig. 5, in an embodiment, the second surface 112 of the glass substrate 110 does not use the second ink layer 121, the OCA glue layer 122, the film 123, the optical texture layer 124, the optical coating layer 125 and the first ink layer 126 to form the decorative layer 120, but directly sprays color ink on the second surface 112 to form the decorative layer 120 with color effect.
In one embodiment, the first surface 111 is exposed, developed, frosted, and the like, and then the anti-fingerprint film layer 130 is attached to the first surface. The anti-fingerprint film layer 130 can fade and decompose the visibility of fingerprint grease through the process characteristics of the anti-fingerprint film layer, and plays a role in preventing fingerprints.
