Abstract

本发明属于玻璃面板技术领域，尤其为电子设备用玻璃面板，包括玻璃基材，所述玻璃基材的表面附着有图案层，所述图案层包括至少一个主图案区、连接于主图案区边缘的延伸图案区以及连接于延伸图案区外侧边缘的完全遮挡区，所述玻璃基材的表面对应完全遮挡区的外缘连接有遮挡层，所述遮挡层靠近完全遮挡区的一侧设有延伸部。本发明利用延伸图案区承接主图案区的边缘图案，作为预备图形部分使用，从而避免了材料的浪费，配合遮挡层与延伸部对完全遮挡区进行完全遮挡，杜绝出现边缘黑边和边缘锯齿现象的同时，无论是先制备图案层或是先制备油墨层，均可得到精细图案，从而保证了产品品质和产品良率。

Description

电子设备用玻璃面板
技术领域
本发明涉及玻璃面板技术领域，具体为电子设备用玻璃面板。
背景技术
传统的电子设备比如移动通讯设备、平板电脑等，通常在其表面贴合有一层玻璃面板，该玻璃面板贴合位于所述电子设备前端面时，通常用以对该电子设备的触摸屏进行保护，其安装位于所述电子设备的后端面时，通常用以做电子设备的后端面进行密封而对电子设备进行保护，即作为电子设备的后端盖而使用。在加工制作玻璃面板时，通常会在玻璃面板表面制作图案；比如为了实现电子设备的部分功能，在玻璃面板的表面通常设置有ICON按键、Home键或者LOGO或其它装饰图案。
传统玻璃面板在进行装饰图案加工时， 通常在玻璃面板表面真空溅镀金属或金属氧化物材料而制作图案层，然后通过在图案层表面涂布覆盖光阻材料进行盖底，在通过曝光显影、蚀刻等工艺，最终形成ICON按键、Home键或者LOGO或其它装饰图案；该工艺虽然制作的产品良率较高，但由于在制作图案过程中，需要采用价格昂贵的曝光设备和光阻材料；直接造成玻璃面板的制作成本居高不下。
为简化工艺，降低玻璃面板的制作成本，技术人员在玻璃面板表面制作装饰图案时，曾尝试采用油墨材料来替代光阻材料来进行图案层盖底，但由于油墨材料自身特性，在对装饰图案制作工程中，图案层的边缘很容易产生毛边或油墨残留，进而造成所制作的装饰图案对外呈现出边缘黑边或锯齿状不良现象，造成产品不良率居高不下；因此，为克服上述产品存在的技术缺陷，有必要对该种电子设备用玻璃面板结构进行改进。
中国专利CN201710057117.7 公开了一种电子设备用玻璃面板，包括玻璃基材，在所述玻璃基材一侧表面设置有由油墨材料制成的油墨层，在所述油墨层内部设置有镂空图形区，所述镂空图形区全部覆盖有由金属或金属氧化物材料所制成的图案层，所述图案层与所述油墨层的周边相连，在所述图案层和所述油墨层外表面还覆盖有由油墨材料制成的盖底层，该盖底层的表面积大于所述图案层与所述油墨层表面积之和；所述图案层相对所述油墨层凹陷而形成有凹槽，所述盖底层覆盖该凹槽；所述油墨层与所述图案层相连的边缘为倾斜边缘，所述图案层的边缘覆盖该油墨层的倾斜边缘。该玻璃面板是通过在图案层的周边设置油墨层，这样，当图案层周边出现毛边时，因其周边与油墨层相连，该毛边由该油墨层边缘所覆盖或遮挡，装饰图案对外不会呈现边缘黑边和边缘锯齿现象，进而在一定程度上达到提高产品品质和产品良率的目的。但上述玻璃面板结构中图案层边缘直接与油墨层周边相连，无论是先制备图案层或先制备油墨层，装饰图案层或油墨层边缘极易受到镀层的污染，无法获得特定装饰图案，导致图案品质受到影响。
发明内容
（一）解决的技术问题
针对现有技术的不足，本发明提供了电子设备用玻璃面板，解决了现有的在图案层周边设置油墨层的玻璃面板结构中图案层边缘直接与油墨层周边相连，无论是先制备图案层或先制备油墨层，装饰图案层或油墨层极易受到镀层的污染，无法获得特定装饰图案，导致图案品质受到影响的问题。
（二）技术方案。
本发明为了实现上述目的具体采用以下技术方案：
电子设备用玻璃面板，包括玻璃基材，所述玻璃基材的表面附着有图案层，所述图案层包括至少一个主图案区、连接于主图案区边缘的延伸图案区以及连接于延伸图案区外侧边缘的完全遮挡区，所述玻璃基材的表面对应完全遮挡区的外缘连接有遮挡层，所述遮挡层靠近完全遮挡区的一侧设有延伸部，所述遮挡层、延伸部与玻璃基材之间形成有用于容置完全遮挡区的凹槽，所述延伸图案区完全容置或部分容置于凹槽内，所述玻璃基材上对应图案层、遮挡层、延伸部的外表面覆盖有盖底层。
进一步地，所述图案层是由金属或金属氧化物材料制成。
进一步地，所述图案层包括数量大于两个的主图案区时，两个主图案区相邻的一侧分别连接有一个延伸图案区，两个延伸图案区之间通过完全遮挡区连接，处于完全遮挡区及两个延伸图案区上表面通过一遮挡层遮挡。
进一步地，处于凹槽内延伸图案区的被遮挡区域表面积不小于内延伸图案区总表面积的四分之三。
进一步地，所述盖底层的表面附着有钢化膜层。
（三）有益效果
与现有技术相比，本发明提供了电子设备用玻璃面板，具备以下有益效果：
本发明，在现有图案层的基础上设计具有延伸图案区与完全遮挡区的装饰图案层，利用延伸图案区承接主图案区的边缘图案，作为预备图形部分使用，从而避免了材料的浪费，配合遮挡层与延伸部对完全遮挡区进行完全遮挡，杜绝出现边缘黑边和边缘锯齿现象的同时，无论是先制备图案层或是先制备油墨层，均可得到精细图案，从而保证了产品品质和产品良率。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例
如图1-3所示，本发明一个实施例提出的电子设备用玻璃面板，包括玻璃基材1，玻璃基材1的表面附着有图案层2，图案层2包括至少一个主图案区201、连接于主图案区201边缘的延伸图案区202以及连接于延伸图案区202外侧边缘的完全遮挡区203；需要说明的是，主图案区201、延伸图案区202与完全遮挡区203的厚度相同，且上表面齐平；玻璃基材1的表面对应完全遮挡区203的外缘连接有由油墨材料制成的遮挡层3，遮挡层3靠近完全遮挡区203的一侧设有延伸部4，遮挡层3、延伸部4与玻璃基材1之间形成有用于容置完全遮挡区203的凹槽；延伸图案区202完全容置或部分容置于凹槽内，具体来说，延伸图案区202的图形与主图案区201的图形可以是承接关系，也可以是相同图案，因此，在制作遮挡层3及延伸部4时，由于可能存在的误差，延伸部4长度未能达到预期标准，此时延伸图案区202便可作为过渡区存在，即使延伸部4制作未能达标，延伸图案区202的装饰图案仍可承接主图案区201的边缘图案，作为预备图形部分使用，避免了材料的浪费；另外，图案区边缘设置完全遮挡区203，由延伸部4完全覆盖，完全杜绝出现边缘黑边和边缘锯齿现象，无论是先制备图案层或是先制备油墨层，均可得到精细图案，从而保证了产品品质和产品良率，从而保证了产品品质和产品良率；玻璃基材1上对应图案层2、遮挡层3、延伸部4的外表面覆盖有盖底层5。
在一些实施例中，图案层2是由金属或金属氧化物材料制成；金属材料可以是铝、钛、铜、银、金或锡等金属，金属氧化物可以是五氧化二铌、氮化硅、二氧化锆、二氧化硅或三氧化二铝等金属氧化物；制作图案层2时，可采用溅射法、真空蒸镀法、化学气相淀积法等制作方法。
如图2所示，在一些实施例中，图案层2包括数量大于两个的主图案区201时，两个主图案区201相邻的一侧分别连接有一个延伸图案区202，两个延伸图案区202之间通过完全遮挡区203连接，处于完全遮挡区203及两个延伸图案区202上表面通过一遮挡层3遮挡；多个主图案区201的使用，能够使装饰图案选择更为灵活，使用范围更广。
在一些实施例中，处于凹槽内延伸图案区202的被遮挡区域表面积不小于内延伸图案区202总表面积的四分之三；为避免图案层2的透光率过高，导致透过延伸图案区202能够观测到完全遮挡区203的轮廓，影响图案观感，在设计时使延伸图案区202至少四分之三区域被延伸部4完全覆盖，即可保证肉眼实现无法透过延伸图案区202看到完全遮挡区203的轮廓，使装饰图案始终保持美感。
如图2所示，在一些实施例中，盖底层5的表面附着有钢化膜层6；透过在盖底层5的表面覆盖钢化膜层6，利用钢化膜层6对盖底层5及玻璃基材1进行防护，防止盖底层5及玻璃基材1直接受到外力的损害、划伤。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
