Description

显示装置及其制造方法
【技术领域】
本申请涉及显示技术领域，具体涉及一种显示装置及其制造方法。
【背景技术】
目前，窄边框及无边框（Bezel-less）设计已成为显示装置的一个发展趋势，由于消减了边框的厚度，用户在欣赏显示画面时就会获得更为广阔的视野，同样的尺寸，其会让人觉得更大。同时，去除边框后，显示装置看起来是一个整体，没有拼接的痕迹，外观更加美观。
显示装置在其至少一侧设置有走线区，显示装置通过走线区接入驱动信号。以具有COF（Chip On Film, 覆晶薄膜）设计的显示装置为例，位于走线区的COF连接显示装置的源极驱动侧。但是，如图1~图3所示，COF 11的表面较为光滑，在对走线区12填充密封胶体13（即填缝处理）时，COF 11与密封胶体13的接触处容易发生附着力不够而出现剥落，即COF 11与显示面板14脱离，影响生产良率。

【具体实施方式】
本申请的主要目的是：对于具有COF的显示装置，在COF的一侧设置凹凸结构，以此提高COF于该侧的粗糙度，从而提高COF与密封胶体的附着力，避免COF剥落，改善生产良率。
本申请可以适用于具有窄边框及无边框设计的显示装置。图4是本申请一实施例的显示装置的结构俯视图。请参阅图4，所述显示装置40包括显示区（Active Area, AA）40a以及位于所述显示区40a的源极驱动侧的走线区40b，该走线区40b内设置有导电元件，该导电元件用于连接柔性电路板（Flexible Circuit Board Assembly, FCBA）41，从而驱动信号输入至所述显示区40a，以实现画面显示。
所述显示装置40包括但不限于LCD（Liquid Crystal Display, 液晶显示器）、OLED（Organic Light-Emitting Diode, 有机发光二极管）显示器。下面结合本申请实施例中的附图，对本申请所提供的各个示例性的实施例的技术方案进行清楚、完整地描述。在不冲突的情况下，下述各个实施例及其技术特征可以相互组合。
图5是本申请第一实施例的COF与显示面板在走线区内的连接示意图。结合图5~图7所示，所述显示装置40还包括显示面板42、COF 43以及密封胶体44，COF 43与柔性电路板41连接并用于为显示面板42提供驱动信号，密封胶体44用于实现填缝处理。
显示面板42包括第一基板421和第二基板422，当然，在显示装置40为LCD的应用场景中，所述显示面板42还包括填充于第一基板421和第二基板422之间的液晶，该液晶位于第一基板421和第二基板422叠加形成的液晶盒内，并且，对应地，所述第一基板421和第二基板422中的一者为阵列基板（Thin Film Transistor Substrate，TFT基板或Array基板），另一者为彩膜基板（Color Filter Substrate，CF基板或彩色滤光片基板）。
本实施例可以设置第一基板421和第二基板422的面积大小不相同，以由面积较大的一者限定所述走线区40b。结合图4~图6所示，以第一基板421的面积大于第二基板422的面积为例，所述第一基板421包括显示区40a和走线区40b，而第二基板422在第一基板421上的正投影与显示区40a重叠。其中，该走线区40b设置有导电的端子，端子通过COF 43与PCBA 41连接，从而接入驱动信号，以控制液晶发生偏转而显示画面。密封胶体44填充于走线区40b并与COF 43的一部分区域接触，在本申请一实施例中，密封胶体44可以由遮光材质制得，以避免显示装置40的走线区40b出现漏光现象。
与现有技术不同的是，本实施例的COF 43的其中一侧分布有颗粒431，具体地，COF 43的一侧（内侧）与显示区40a连接以用于向显示面板42提供驱动信号，而COF 43的另一侧（外侧）分布有颗粒431，这些颗粒431的粒径大小可以相同，也可以不相同。应理解，如图7所示，颗粒431并非分布于COF 43的整个外侧，而是仅分布于COF 43外侧的一部分区域，这部分区域为COF 43与密封胶体44接触的区域。其中，颗粒431可视为设置于COF 43外侧的凹凸结构，于此，COF 43外侧的于该侧的粗糙度得以提高，从而能够提高COF 43与密封胶体44的附着力，避免COF 43剥落。
在实际应用场景中，COF 43的凹凸结构可以采用涂布颗粒的方式形成。以颗粒431为树脂颗粒为例，在将COF 43与显示区40a连接之前，在COF 43外侧的与密封胶体44的待接触区域涂布非固态树脂，然后通过光照（例如紫外光照射）对其进行固化，以此形成所述凹凸结构。
图9是本申请第二实施例的COF与显示面板在走线区内的连接示意图，图10是图9所示显示装置的COF的结构俯视图。为便于描述，对相同的结构元件，本实施例采用与上述实施例相同的标号进行标识。结合图4、图9和图10所示，在前述实施例的描述基础上，但与之不同的是，本实施例的COF 43的外侧贴附有膜432，这层膜432的外表面凹凸不平。应理解，如图10所示，膜432并非贴附于COF 43的整个外侧，而是仅分布于COF 43外侧的一部分区域，这部分区域为COF 43与密封胶体44接触的区域。其中，膜432（或者说膜432的外表面）可视为设置于COF 43外侧的凹凸结构，于此，COF 43外侧的粗糙度较高，从而能够提高COF 43与密封胶体44的附着力，避免COF 43剥落。
在实际应用场景中，所述膜432可以为胶带，在将COF 43与显示区40a连接之前，在COF 43外侧的与密封胶体44的待接触区域粘接胶带，胶带的内表面与COF 43外侧粘接，以此形成所述凹凸结构。
应该理解到，本申请上述各个实施例的显示装置40还包括有其他组件，例如显示装置40还包括侧框，该侧框与密封胶体44的外边缘相抵接；再例如，在显示装置40为LCD的应用场景中，所述显示装置40还包括背光模组；又例如，COF 43的内侧还设置有驱动IC 433。这些组件的设计可参阅现有技术。
图11本申请一实施例的显示装置的制造方法的流程示意图。如图11所示，所述显示装置的制造方法可以包括步骤S111~S113。
S111：提供一显示面板，所述显示面板包括显示区和走线区。
S112：在走线区设置COF，所述COF的一侧与显示区连接以用于向显示区提供驱动信号，COF的另一侧设有凹凸结构。
S113：密封胶体覆盖于COF的凹凸结构。
所述制造方法可用于制造上述实施例的显示装置40，基于此：
在步骤S112中，本实施例可以采用涂布颗粒的方式形成所述COF的凹凸结构。以颗粒为树脂颗粒为例，在将COF与显示区连接之前，将所述COF的另一侧的与密封胶体的待接触区域涂布非固态树脂，然后通过光照（例如紫外光照射）对其进行固化，以此形成所述凹凸结构。
当然，本实施例也可以采用贴膜的型的方式形成所述COF的凹凸结构。例如，在将COF与显示区连接之前，在所述COF的另一侧的与密封胶体的待接触区域贴附外表面凹凸的膜。
由于本实施例的制造方法可用于制造与上述显示装置40相同结构的显示装置，因此具有与其相同的有益效果。
应理解，以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，例如各实施例之间技术特征的相互结合，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
