Technical Field

The invention relates to the technical field of glass panels, in particular to a glass panel for electronic equipment.

Background

In a conventional electronic device, such as a mobile communication device, a tablet computer, etc., a glass panel is usually attached to a surface of the electronic device, and when the glass panel is attached to a front end surface of the electronic device, the glass panel is usually used for protecting a touch screen of the electronic device. When a glass panel is manufactured, a pattern is usually formed on the surface of the glass panel; for example, in order to realize part of the functions of the electronic device, an ICON button, a Home button, or a LOGO or other decorative patterns are usually disposed on the surface of the glass panel.

When the traditional glass panel is used for processing decorative patterns, metal or metal oxide materials are generally sputtered on the surface of the glass panel in a vacuum mode to manufacture a pattern layer, then a covering photoresist material is coated on the surface of the pattern layer to cover the pattern layer, and an ICON key, a Home key or LOGO or other decorative patterns are finally formed through processes such as exposure, development, etching and the like; although the yield of the manufactured product is high, expensive exposure equipment and photoresist materials are needed in the process of manufacturing the pattern; directly causes the manufacturing cost of the glass panel to be high.

In order to simplify the process and reduce the manufacturing cost of the glass panel, technicians try to adopt ink materials to replace photoresist materials to cover the bottom of the pattern layer when manufacturing decorative patterns on the surface of the glass panel, but because of the characteristics of the ink materials, burrs or ink residues are easily generated on the edge of the pattern layer in the manufacturing process of the decorative patterns, so that the manufactured decorative patterns have the bad phenomenon of black edges or saw-toothed shapes on the edge, and the product reject ratio is high; therefore, in order to overcome the technical defects of the above products, there is a need for an improved glass panel structure for electronic devices.

Chinese patent CN201710057117.7 discloses a glass panel for electronic devices, which comprises a glass substrate, wherein an ink layer made of an ink material is arranged on the surface of one side of the glass substrate, a hollowed-out pattern area is arranged inside the ink layer, the hollowed-out pattern area is completely covered with a pattern layer made of a metal or metal oxide material, the pattern layer is connected with the periphery of the ink layer, the outer surfaces of the pattern layer and the ink layer are also covered with a cover bottom layer made of an ink material, and the surface area of the cover bottom layer is larger than the sum of the surface areas of the pattern layer and the ink layer; the pattern layer is sunken relative to the ink layer to form a groove, and the bottom cover layer covers the groove; the edge of the ink layer connected with the pattern layer is an inclined edge, and the edge of the pattern layer covers the inclined edge of the ink layer. This glass panels sets up the printing ink layer through the periphery at the pattern layer, like this, when deckle edge appears in pattern layer periphery, because of its periphery links to each other with the printing ink layer, this deckle edge is covered or shelters from by this printing ink layer edge, and decorative pattern outwards can not present marginal black limit and marginal sawtooth phenomenon, and then reaches the purpose that improves product quality and product yield to a certain extent. However, the edge of the pattern layer in the glass panel structure is directly connected with the periphery of the ink layer, and no matter the pattern layer is prepared or the ink layer is prepared, the edge of the decorative pattern layer or the ink layer is easily polluted by the coating, and a specific decorative pattern cannot be obtained, so that the pattern quality is influenced.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1-3, a glass panel for electronic devices according to an embodiment of the present invention includes a glass substrate 1, a pattern layer 2 attached to a surface of the glass substrate 1, the pattern layer 2 including at least a main pattern region 201, an extended pattern region 202 connected to an edge of the main pattern region 201, and a completely shielding region 203 connected to an outer edge of the extended pattern region 202; it should be noted that the thickness of the main pattern region 201, the extended pattern region 202 and the complete shielding region 203 are the same, and the upper surfaces are flush; the outer edge of the surface of the glass substrate 1 corresponding to the complete shielding area 203 is connected with a shielding layer 3 made of an ink material, one side of the shielding layer 3 close to the complete shielding area 203 is provided with an extension part 4, and a groove for accommodating the complete shielding area 203 is formed among the shielding layer 3, the extension part 4 and the glass substrate 1; the extension pattern area 202 is completely or partially accommodated in the groove, specifically, the pattern of the extension pattern area 202 and the pattern of the main pattern area 201 can be in a connection relationship or the same pattern, therefore, when the shielding layer 3 and the extension portion 4 are manufactured, the length of the extension portion 4 fails to reach the expected standard due to possible errors, and at this time, the extension pattern area 202 can be used as a transition area, even if the extension portion 4 is not manufactured to reach the standard, the decorative pattern of the extension pattern area 202 can still support the edge pattern of the main pattern area 201 to be used as a preliminary pattern part, thereby avoiding the waste of materials; in addition, the edge of the pattern area is provided with the complete shielding area 203 which is completely covered by the extension part 4, so that the phenomena of edge black edges and edge saw teeth are completely avoided, no matter the pattern layer is prepared firstly or the ink layer is prepared firstly, fine patterns can be obtained, the product quality and the product yield are ensured, and the product quality and the product yield are ensured; the outer surfaces of the glass substrate 1 corresponding to the pattern layer 2, the shielding layer 3 and the extension portion 4 are covered with a cover bottom layer 5.

In some embodiments, the pattern layer 2 is made of a metal or metal oxide material; the metal material can be metal such as aluminum, titanium, copper, silver, gold or tin, and the metal oxide can be metal oxide such as niobium pentoxide, silicon nitride, zirconium dioxide, silicon dioxide or aluminum oxide; the pattern layer 2 may be formed by a sputtering method, a vacuum evaporation method, a chemical vapor deposition method, or the like.

As shown in fig. 2, in some embodiments, when the pattern layer 2 includes more than two main pattern areas 201, one extended pattern area 202 is connected to each of two adjacent sides of the two main pattern areas 201, the two extended pattern areas 202 are connected by a full shielding area 203, and the upper surfaces of the two extended pattern areas 202 and the full shielding area 203 are shielded by a shielding layer 3; the use of a plurality of master pattern areas 201 enables the decorative pattern selection to be more flexible and the application range to be wider.

In some embodiments, the masked area surface area of the extended pattern area 202 within the recess is no less than three quarters of the total surface area of the extended pattern area 202; in order to avoid the too high transmittance of the pattern layer 2, which may cause the outline of the completely shielded region 203 to be observed through the extended pattern region 202, and affect the pattern appearance, at least three-fourths of the extended pattern region 202 is completely covered by the extended portion 4 during the design, so as to ensure that the outline of the completely shielded region 203 cannot be seen through the extended pattern region 202 by naked eyes, and the decorative pattern can be maintained at aesthetic feeling all the time.

As shown in fig. 2, in some embodiments, a toughened film layer 6 is attached to the surface of the cover bottom layer 5; the toughened film layer 6 covers the surface of the cover bottom layer 5, and the cover bottom layer 5 and the glass substrate 1 are protected by the toughened film layer 6, so that the cover bottom layer 5 and the glass substrate 1 are prevented from being directly damaged and scratched by external force.
