Description

一种显示面板及其制备方法
本申请要求于2019年05月17日提交中国专利局、申请号为201910414168.X、发明名称为“一种显示面板及其制备方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本揭示涉及显示技术领域，尤其涉及一种显示面板及其制备方法。
 背景技术
在实际生产中，为了保持盖板与面板之间的间隙为定值。通常在设计上，会将间隙层的气压小于外在大气压，透过气压差造成的压力使间隙为定值。然而，由于液晶面板成盒时也是采用低压灌入液晶，利用大气压力使液晶厚度为均匀状态。
如图1所示，显示面板包括液晶面板1、盖板2、框胶层3、以及缝隙100。液晶面板1与盖板2相对设置，且通过框胶层3彼此贴合。框胶层3设于液晶面板1的边缘处与盖板2的边缘处，且围成矩形环状结构，环状结构中部设有缝隙100。在常压下，由于盖板与液晶面板之间存在着大气压力，液晶面板内的液晶受到均匀的大气压，液晶的厚度不会发生变化。
为了使得盖板与液晶面板紧密贴合，需要在真空或低压的状态下，对间隙进行抽真空处理。
如图2所示，在真空或低压的状态下，盖板2与液晶面板1受到大气压强影响，中部紧密贴合在一起。由于盖板2的边缘处与液晶面板1的边缘处之间存在一定厚度的框胶层3，盖板2与液晶面板1无法完全贴合，会发生一定程度的翘曲变形，压合处理完成后，靠近框胶层3内侧边缘处会存在间隙200。由于液晶面板1发生一定程度的翘曲变形，其中部受到较大的压力，位于液晶面板边缘处的液晶层的厚度会大于位于液晶面板中心处的液晶层的厚度，导致液晶面板内液晶的分布不均。
液晶显示面板的穿透率是由液晶层的厚度决定的。因此，当位于液晶面板边缘处的液晶层的厚度会大于位于液晶面板中心处的液晶层的厚度时，液晶面板边缘处的光穿透率大于液晶面板中心处的光穿透率，导致整个液晶面板的光穿透率不一，进而造成显示面板出现亮边或者显示不均的现象。

 本发明的实施方式
以下参考说明书附图介绍本揭示的优选实施例，用以举例证明本揭示可以实施，这些实施例可以向本领域中的技术人员完整介绍本揭示的技术内容，使得本揭示的技术内容更加清楚和便于理解。然而本揭示可以通过许多不同形式的实施例来得以体现，本揭示的保护范围并非仅限于文中提到的实施例。
如图3所示，本揭示提供一种显示面板，包括液晶面板1、盖板2、框胶层3以及支撑层4。
液晶面板1内被液晶填充，通过设置液晶的排列，以达到遮光和透光的目的，使得显示面板显像。
盖板2与液晶面板1相对设置，贴附于液晶面板1的上表面。盖板2的形状与液晶面板1的形状相同；盖板2的尺寸与液晶面板1的尺寸相同。
框胶层3呈环状，设于液晶面板1边缘处与盖板2边缘处之间，即位于显示面板的非显示区。液晶面板1、盖板2与框胶层3围成至少一间隙。
支撑层4填满所述间隙，其材质为胶体，使得盖板2与液晶面板1在大气压的作用下紧密贴合在一起，且不会因为框胶层2的厚度而导致液晶面板1内的液晶层厚度不均、光穿透率不一的技术问题，避免显示面板出现亮边的现象。支撑层4的材质可以为OCA光学胶、双面胶等胶体，只要具有良好的粘合性即可。
本实施提供的显示面板，在框胶层内侧设置支撑层，可以使得盖板与液晶面板完全贴合，且液晶面板内的各个位置的液晶厚度相同，穿透率均匀，提升显示面板的质量。另外，当显示面板具有触控功能时，由于在框胶层内侧设置具有一定斜率的支撑层，可以克服在触控时，显示面板出现光学干涉（水波纹或牛顿环）的问题显著提供显示效果，进而使得用户在盖板上操作具有良好的灵敏度，提高用户体验。
如图4所示，本实施例还提供一种显示面板的制备方法，包括如下步骤S1~S5。
S1液晶面板提供步骤，提供一液晶面板。
S2框胶层制备步骤，在所述液晶面板上表面的边缘处制备一环形的框胶层。
所述框胶层由光学胶条首尾衔接成环状的。光学胶（Solid Optically Clear Adhesive）是一种UV、湿气双重固化光学胶，在UV光照条件下可固化。本实施例中，所述框胶层的宽度较窄，这样有利于使显示面板实现窄边框，而且还可以节省大量的光学胶材料，降低生产成本。
S3支撑层制备步骤，在所述液晶面板上表面制备一环形的支撑层，位于所述框胶层内侧。
如图5所示，在液晶面板1上表面制备支撑层4的过程中，支撑层4的高度与框胶层3高度一致，支撑层4底面与液晶面板1上表面相切，支撑层4侧面与框胶层3内侧面相切，避免支撑层4与框胶层3的高度不一的现象。
所述支撑层4包括一斜面，从所述框胶层4顶部延伸至所述液晶面板1的上表面；所述斜面的斜率为所述支撑层4的高度与其底面宽度的比值。
本实施例中，所述显示面板包括显示区10和非显示区20，所述框胶层3与所述支撑层4位于非显示区。所述支撑层4的宽度为所述框胶层3内侧到显示区10外侧的距离，所述支撑层4的高度为所述框胶层3的高度，所述支撑层4的斜率为所述框胶层3的高度与所述框胶层3内侧到显示区10外侧的距离的比值。因此，本领域技术人员在设置支撑层前，可以根据通过测量所述框胶层内侧到显示区外侧的距离与所述框胶层的高度，得到所述支撑层的斜率，根据该斜率设置支撑层。
本实施例中，所述支撑层透明的材质为胶体，对产品的外观没有影响。所述支撑层的结构近似于直角三角形。
S4盖板贴附步骤，贴附一盖板至所述液晶面板上表面。
采用CCD对位方式或冶具辅助定位方式，使得所述盖板的边缘处贴附于所述液晶面板的边缘处。
S5抽真空步骤，对所述环形框胶层及所述支撑层围成的空间做抽真空处理，使得所述盖板贴合至所述液晶面板。
将所述盖板、所述液晶面板送进一密封腔体内，利用真空泵将对所述环形框胶层及所述支撑层围成的空间做抽真空处理，以及利用加热装置对所述盖板、所述液晶面板进行加热处理，使得所述盖板贴合至所述液晶面板。
在加热和加压的过程中，所述框胶层、所述支撑层会被加热固化，使得所述盖板的边缘处于所述液晶面板的边缘处紧密贴合。所述框胶层、所述支撑层在固化后，形成一个环状结构，优选为矩形环。
本实施例提供的显示面板制作方法，通过在框胶层内侧设置支撑层，在大气压的作用下，可以使得盖板与液晶面板完全贴合，且液晶面板内的各个位置的液晶层厚度相同，光穿透率均匀，提升显示面板的质量。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
