Description

显示装置 技术领域
本发明涉及显示技术领域，具体涉及一种显示装置。
 背景技术
有机发光二极管（Organic Light Emitting Diode，OLED）作为一种电流型发光器件，因其具有自发光、色彩丰富、响应速度的快、视角广、重量轻以及可做成柔性显示屏等优点而受到广泛关注。
随着产品的不断升级，窄边框设计成为了一种趋势。窄边框设计要求减小边缘无显示区域的宽度，尤其是下边框的宽度。目前，常用的封装方案是将芯片镶嵌在了柔性线路板上，也就是附着在了屏幕和主板之间的排线之上。然后在此基础上，将柔性线路板弯折到屏幕背面，实现窄边框设计。
但是由于将柔性线路板弯折到屏幕背面，弯折区域会存在一定的应力集中，特别在弯折区域的周边应力相对较大。因此会造成弯折区域出现断裂或者破裂的情况，从而降低了产品良率。

下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
请参阅图1以及图2，图1为本申请提供的显示装置的第一种实施方式的结构示意图，图2为图1的显示装置处于弯折状态时的结构示意图。
本申请实施例提供一种显示装置1，包括：
显示面板10，显示面板10包括显示区域101以及设置在显示区域101外的绑定区域102；
柔性线路板20，柔性线路板20包括主体部201以及设置在主体部201一侧的连接部202，连接部202设置在绑定区域102上；
其中，连接部202包括第一端部2021，以及与第一端部2021相连接且沿第一端部2021到显示区域101的方向延伸的至少一个第二端部2022。
该显示面板10为液晶显示面板或者柔性OLED显示面板。以柔性OLED显示面板为例，该显示面板10上形成有光学器件，该光学器件包括层叠设置的阳极、有机发光层以及阴极。其中，该显示面板10包括显示区域101以及绑定区域102。该显示区域101用于显示画面，绑定区域102上设置有金属排线，显示区域101上的驱动线、数据线以及电源线通过金属排线与设置在绑定区域102上的柔性线路板20相连接。该柔性线路板20包括主体部201，以及设置在主体部201一侧的连接部202，并且该连接部202设置在绑定区域102上。其中，连接部202包括第一端部2021，以及与第一端部2021相连接且沿第一端部2021到显示区域101的方向延伸的至少一个第二端部2022。该第二端部的2022的尺寸具体根据显示面板10的尺寸进行设定。该第二端部2022的形状为矩形、圆形、三角形或者梯形。
并且，该第一端部2021与第二端部2022一体成型。即，在生产该柔性线路板20时，一并制作该第一端部2021与第二端部2022。
在申请实施例中，通过在柔性线路板20的连接部202上设置至少一个第二端部2022，当柔性线路板202弯折时，第二端部2022可分散一部分应力，避免弯折区域出现断裂或者破裂的情况。因此，提高了产品良率。
请参阅图3以及图4,，图3为本申请提供的显示装置的第二种实施方式的结构示意图，图4为图3的显示装置处于弯折状态时的结构示意图。
显示装置还包括驱动芯片30，驱动芯片30设置在绑定区域102上；其中，第一端部2021以及第二端部2022均设置在驱动芯片周缘。
其中，第二端部2022的数量可以根据实际情况进行设定。比如，第二端部2022的数量为一个，且该第二端部2022设置在驱动芯片30任一侧，如图3所示。当显示面板10弯折时，设置在驱动芯片30一侧的一个的第二端部2022分散部分弯折的应力，减小弯折区域的应力，使得弯折区域不会由于弯折而出现断裂或破裂的情况。因此，提高了产品良率。并且，由于在连接部202上设置有第二端部2022，增加了柔性线路板20与绑定区102的接触面积。在弯折时，柔性线路板20不易脱落。因此，进一步提高了产品良率。
又比如，第二端部2022的数量为四个，其中两个第二端部2022设置在驱动芯片30一侧，其中两个第二端部2022设置在驱动芯片30另一侧，如图5所示。当显示面板10弯折时，设置在驱动芯片30一侧的两个的第二端部2022以及设置在驱动芯片30另一侧的两个第二端部2022分散部分弯折的应力，减小弯折区域的应力，使得弯折区域不会由于弯折而出现断裂或破裂的情况。因此，提高了产品良率。并且，由于在连接部202上设置有四个第二端部2022，增加了柔性线路板20与绑定区102的接触面积。在弯折时，柔性线路板20不易脱落。因此，进一步提高了产品良率。
请参阅图6以及图7，图6为本申请提供的显示装置的第四种实施方式的结构示意图，图7为图6的显示装置处于弯折状态时的结构示意图。
绑定区域102包括相互连接的第一子区域1021、弯折子区域1022以及第二子区域1023；
其中，第一子区域1021与显示区域101连接，弯折子区域1022设置在第一子区域1021与第二子区域1023之间，驱动芯片30以及第一端部2021均设置在第二子区域1023上。
在本实施例中，第一子区域1021为与显示区域101连接的水平区域，弯折子区域1022设置在第一子区域1021和第二子区域1023之间，且该弯折子区域1022用于弯折。第二子区域1023上设置有芯片30和第一端部2021。并且，具体实施时，该第二子区域1023翻折到显示面板10的背面，以实现窄边框设计，如图6所示。此外，该第二端部2022均设置在第二子区域1023上。比如，连接部202上包括5个第二端部2022，则这5个第二端部2022均设置在第二子区域1023上。又比如，连接部202仅有一个第二端部2022，则这个第二端部2022设置在第二子区域1023上。当然，第二端部2022的数量也可以为3个，在本实施例中仅仅只是举例说明，不作为对本申请的限制。
在本实施例中，通过在连接部202上设置第二端部2022，当显示面板弯折时，不会造成弯折区域断裂，即不会造成弯折子区域1022断裂，从而导致显示面板失效。因此，提高了产品良率。
第二端部2022包括相互连接的第一段21、弯折段22和第二段23，第一段21设置在第一子区域1021上，弯折段22设置在弯折子区域1022上，第二段23设置在第二子区域1023上。
在本实施例中，第二端部2022包括相互连接的第一段21、弯折段22和第二段23，并且，将第一段21设置在第一子区域1021上，弯折段22设置在弯折子区域1022上，第二段23设置在第二子区域1023上。当显示面板弯折时，第一段21、弯折段22和第二段23均会分散部分弯折区的应力，不会造成弯折区域断裂，即不会造成弯折子区域1022断裂，从而导致显示面板失效。因此，提高了产品良率。并且，将第一段21设置在第一子区域1021上，弯折段22设置在弯折子区域1022上，第二段23设置在第二子区域1023上，增加了柔性线路板20与绑定区域102的接触面积，从而较少柔性线路板20在弯折时脱落的风险，因此提高了产品良率。
请参阅图8，图8为本申请提供的显示装置的第五种实施方式的结构示意图。
第二端部2022包括相对设置的第一子端部210和第二子端部220；其中，第一子端部210设置在驱动芯片30一侧，第二子端部220设置在驱动芯片30另一侧。
第一子端部210与第二子端部220的形状、大小均一致。
例如，当显示面板10弯折时，第二端部2022上的第一子端部210和第二子端部220可以吸收一部分弯折时的应力，减少显示面板10的弯折子区域1022断裂的风险。并且，还可以提高柔性线路板20与绑定区102的贴合性能，进一步提高了产品良率。
以上对本申请实施例提供的显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
