Description

一种显示屏的玻璃面板以及显示屏 技术领域
本公开涉及显示屏技术领域，特别是涉及一种显示屏的玻璃面板以及显示屏。
背景技术
随着大尺寸显示屏技术的发展，人们消费水平的不断提高，具有大尺寸显示屏的产品，例如电视产品受到越来越多消费者的喜爱。
具有大尺寸显示屏的电视产品常见的一种缺陷是显示屏角落漏光，具体的：在显示屏的下方两个角落低灰阶发亮，呈现扩散状漏光，严重影响了高级超维场转换技术(Advanced Super Dimension Switch，ADS)电视产品的品质。
出现上述问题的原因如下。显示屏玻璃面板被切割后，由于受玻璃内应力影响，会有一定的收缩，图中1中细实线示出了由于内应力影响收缩后的玻璃面板1。图中1中粗实线示出了显示屏的背光胶框。玻璃面板的尺寸越大，收缩量越大。组装后，显示屏垂直放置时受重力作用，显示屏玻璃面板仅左右两个角落压在背光胶框上(图1中虚线所示)，显示屏玻璃面板在角落处受挤压产生应力形变，改变了偏振光的正常传播偏振方式，产生漏光。
传统的改善方法是增加显示屏内液晶量，降低液晶受应力的影响。但此方法严重压缩了液晶(Liquid Crystal，LC)量范围，与此同时还带来了重力性显示不均问题，所以此方法存在严重缺陷且不能有效改善角落漏光。
发明内容
鉴于上述问题，提出了本申请实施例以便提供一种克服上述问题或者至少部分地解决上述问题的一种显示屏的玻璃面板以及显示屏。
为了解决上述问题，本申请实施例公开了一种显示屏的玻璃面板，所述玻璃面板的各边相对于各边的两端点之间的连线逐渐外突，各边的一端点与各边中点之间的各边上的点与两端点之间的连线的垂直距离，沿该端点到中点的方向逐渐增加。
优选地，所述玻璃面板的各边具有至少3个切割对位点，所述切割对位点用以在所述玻璃面板切割时分段对位。
优选地，所述玻璃面板的外形的突出量与收缩量相同，其中，所述突出量是指所述玻 璃面板切割时各边超出所述玻璃面板各边端点连线范围时，各边上的点与所述玻璃面板各边端点连线之间的垂直距离，所述收缩量是指所述玻璃面板切割后各边在垂直于各边端点连线方向上的形变量。
优选地，所述切割对位点包括所述玻璃面板的各边的两个端点。
优选地，所述玻璃面板的长边突出量大于所述玻璃面板的短突出量。
优选地，所述各边为相对于各边的中点对称的形状。
优选地，所述玻璃面板的外形轴对称和/或中心对称。
优选地，所述玻璃面板的各边为圆弧形，所述圆弧形的对应的圆心角小于0.04度。
优选地，所述玻璃面板的各圆弧形的边对应的圆圆心角相同和/或所述玻璃面板的各圆弧形对应的圆的直径相同。
为了解决上述问题，本申请实施例还公开了一种显示屏，所述显示屏包括上述的玻璃面板。
本申请实施例包括以下优点：
本申请实施例中，通过将显示屏玻璃面板外形设计成各边中点到两端点渐变的突出型形状，且各边的一端点与各边中点之间的各边上的点与两端点之间的连线的垂直距离，沿该端点到中点的方向逐渐增加，当组装该切割后的玻璃面板时，由于其内应力导致的收缩，该玻璃面板的实际外形是四边齐整的标准矩形，最终能够实现玻璃面板多点或整边接触显示屏的背光胶框，改善显示屏玻璃面板内应力引起的形变以及其导致的显示屏角落漏光问题。
附图说明
为了更清楚地说明本申请实施例的技术方案，下面将对本申请实施例的描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1是一种现有的显示屏玻璃面板切割后应力收缩后形变示意图；
图2是根据本申请实施例的一种显示屏玻璃面板外形示意图；
图3是一种显示屏的结构示意图；
图4是本申请实施例的一种玻璃面板组装成显示屏成品后外形示意图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参照图2，示出了本申请实施例一种显示屏玻璃面板外形示意图，该玻璃面板可以应用于较大尺寸显示屏，以克服大尺寸显示屏电子产品下方两个角落低灰阶发亮，呈现扩散状漏光的问题。
在本申请实施例中，该显示屏玻璃面板外形为各边相对于各边的两端点之间的连线逐渐外突，在各边上，各边的一端点与各边中点之间的点与两端点之间的连线的垂直距离，沿该端点到中点的方向逐渐增加。如图2所示，所述玻璃面板的各边具有至少3个的切割对位点(Cutting Mark)3，所述切割对位点用以在所述玻璃面板切割时分段对位。
具体的，如图3所示，显示屏通常可以包括玻璃面板4、背光胶框(Bezel)5、光学膜片6、背板7、发光二极管8(Lighting Emitting Diode，LED)光源、电路驱动系统等，其中玻璃面板中可以填充液晶材料，从而可以通过电压来改变液晶材料内部分子的排列状况，以达到遮光和透光的目的来显示深浅不一，错落有致的图像。
在具体实现中，在组装显示屏前，该显示屏的玻璃面板可以从一整块大玻璃中通过在玻璃表面上预设位置设有的切割对位点切割出的一小块预设尺寸的玻璃，以备组装时备用，其中切割对位点用以该玻璃面板切割时的对位。
本申请实施例为了抵消该玻璃面板切割后其内应力导致的向内收缩的影响，可以将该玻璃面板切割时的外形设计成各边相对于各边的两端点之间的连线逐渐外突，在各边上，各边的一端点与各边中点之间的点与两端点之间的连线的垂直距离，沿该端点到中点的方向逐渐增加，以下将该外形称为“各边中点到两端点渐变的突出型形状”。
为了便于将该玻璃面板切割时形状设计为各边中点到两端点渐变的突出型形状，可以在该玻璃面板的各边设置有至少3个切割对位点切割对位点，这些切割对位点将玻璃面板的各边分成多个小段，因此对位时可以分段对位，便于将该玻璃面板各边切割成突出的中点到两端点渐变的突出型形状。
为了便于设置切割对位点的位置，该切割对位点包括玻璃面板的各边的两个端点。
为了更好的抵消该玻璃面板切割后其内应力导致的向内收缩的影响，可以将该玻璃面 板的外形的突出量与收缩量相同，其中，所述突出量是指所述玻璃面板切割时各边超出所述玻璃面板各边端点连线范围时，各边上的点与所述玻璃面板各边端点连线之间的距离，例如为最大距离，所述收缩量是指所述玻璃面板切割后各边在垂直于各边端点连线方向上的形变量，例如为各边上的点与所述玻璃面板各边端点连线之间的最大距离。
在本申请实施例中，为了获取某一预设尺寸显示屏的玻璃面板各边的收缩量，可以收集某一预设数量的显示屏玻璃面板，分别测量出各边的收缩量，通过求取平均值或加权平均值的方法计算出各边的收缩量，作为玻璃面板外形突出量的参考。
作为一种示例，通过上述方法可以获取65英寸(inch)的玻璃面板长边中点的收缩量范围在0.8mm～1.0mm之间，短边中点的收缩量范围在0.06～0.09mm之间。
当然，本领域技术人员还可以通过其他方法计算某一预设尺寸显示屏的玻璃面板各边的收缩量，本申请实施例对此不作限制。
在本申请实施例中，如果在实际中玻璃面板的各边收缩量不便于获取，可以仅仅获取某一宽边上中点的收缩量，由于该边上的其中一端点的收缩量为零，中点的收缩量最大，因此，对应的，该某一宽边上中点的突出量设置为最大，端点设置为零，由于不便于获取其他点的突出量，可以通过数学曲线的方法模拟出一段平滑的从一端点到中点渐变的突出形状，然后通过轴对称的方法补齐该某一宽边中点到另一端点的渐变的突出形状，最后可以通过轴对称和/或中心对称的方法补齐对边的渐变的突出形状。
同样地，对于长边的渐变的突出形状的设计方法，可以参照上述宽边的方法，本申请实施例在此不作赘述。
需要说明的是，通常长边的收缩量大于宽边的收缩量，因此长边的突出量会大于宽边的突出量。
在本申请的一种优选实施例中，上述数学曲线可以包括圆弧，椭圆弧，双曲线弧。
在本申请的另一种优选实施例中，为了使圆弧更好的模拟实际情况，各边对应的圆弧的圆心角小于0.04度，且各对边对应的圆弧对应的圆心角相同和/或所述Panel的各对边对应的圆弧对应的直径相同。
基于上述玻璃面板切割时将各边设计成各边中点到两端点渐变的突出型形状，切割后，由于玻璃面板的玻璃内应力的影响，该玻璃面板会向内收缩，由于突出量与收缩量抵消，因此，如图4示出的本申请实施例的一种玻璃面板组装成显示屏成品后外形示意图所示，本申请实施例切割后的玻璃面板组装成显示屏成品100后其形状仍然是标准的矩形。
本申请实施例中，通过将显示屏玻璃面板上设置3个以上的切割对位点，从而便于切 割时将玻璃面板切割成各边中点到两端点渐变的突出型形状，当组装该切割后的玻璃面板时，由于其内应力导致的收缩，该玻璃面板的实际外形是四边齐整的标准矩形，最终能够实现玻璃面板多点或整边接触显示屏的背光胶框，改善显示屏玻璃面板内应力引起的形变以及其导致的显示屏角落漏光问题。
在本公开的另一种实施例中，还可以通过首先根据预先获取的收缩量将玻璃面板切割成比预设尺寸玻璃面板略大的标准矩形，然后通过磨边工艺调整，使得玻璃面板为四边突出的形状。即切割完成后，通过调节磨边速度与转速等，使得磨边程度从各边的中部到两端逐渐增加，形成各边中点到两端点渐变的突出型形状。
本申请实施例中，通过预先获取玻璃面板各边收缩量，将玻璃面板切割成已经考虑收缩量的比预设尺寸玻璃面板略大的标准矩形玻璃面板，切割后，通过磨边工艺调整，将标准矩形玻璃面板打磨成与各边收缩量相适应的四边突出形状的玻璃面板，从而当该玻璃面板实际组装成显示屏时，玻璃面板经过内应力而收缩，使得其实际外形仍然是各边齐整的标准矩形，最终实现玻璃面板多点或整边接触显示屏的背光胶框，改善显示屏玻璃面板内应力引起的形变以及其导致的显示屏角落漏光问题。
需要说明的是，上述实施例可以相互组合，以便实现更好的改善显示屏角落漏光问题。
本申请实施例还公开了一种显示屏，该显示屏包括玻璃面板。
在本申请实施例中，关于玻璃面板的描述可以参照前述实施例的描述，本实施例对此不再赘述。
在本申请实施例中，该显示屏包括的玻璃面板在组装成显示屏时，该玻璃面板各边上多点或所述玻璃面板的各整边在组装所述显示屏时紧密贴合所述显示屏的背光胶框。
尽管已描述了本申请实施例的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例做出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请实施例范围的所有变更和修改。
最后，还需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者终端设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者终端设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限 定的要素，并不排除在包括所述要素的过程、方法、物品或者终端设备中还存在另外的相同要素。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
