显示模组及显示装置 技术领域
本申请涉及显示领域，尤其涉及一种显示模组及显示装置。
 背景技术
随着全面屏普及程度越来越高，用户不仅对全面屏的功能及性能要求越来越高，对全面屏的外观也有了更高的要求。具有更窄边框的全面屏，能够提供更大的有效显示面积，进而提供更好的视觉体验。
然而，在显示面板中，由于边缘走线的存在，显示面板的边框很难再减小。因此，减小显示模组的边框、以及显示模组与整机壳体之间的组装边框成为减小显示器件边框的研究方向。为了保证显示模组与整机机壳之间具有良好的组装效果，显示模组需要预留宽度大于1毫米的组装边界与整机机壳连接，这就造成显示模组的边框和显示装置的边框面积较大，无法实现高显示占比，影响视觉体验。

具体的，请参照图2，在一种实施例中，所述显示面板10包括平面区104、弯曲区105和绑定区106，所述绑定区106通过所述弯曲区105弯曲绑定于所述平面区104的背光面。在所述平面区104内，所述显示面板10包括从出光面到背光面的显示基板11、第一支撑板12、散热板13和第二支撑板14。所述显示基板11可以是LED显示基板、MLED显示基板、OLED显示基板、LCD显示基板等，在此不做限定。在所述平面区104内，所述显示基板11包括电路基板111和膜层结构112，所述膜层结构112位于所述电路基板111和所述盖板20之间，所述电路基板111靠近所述弯曲区105的侧边突出于所述膜层结构112靠近所述弯曲区105的侧边。在所述弯曲区105和所述绑定区106内，所述显示面板10包括电路层113和胶层114，所述胶层114设于所述电路层113背离所述散热板13的表面，用于保护所述电路层113。所述绑定区106和所述平面区104之间存在面板间隙102，所述面板间隙102的形状和尺寸由所述第一支撑板12、散热板13和第二支撑板14的侧边尺寸，以及所述弯曲区105的弯曲形态决定。

在一种实施方案中，请参照图2，所述显示面板10的弯曲区105和至少部分绑定区106位于所述绑定部32内，所述绑定部32包括第一侧壁326和第一底部323，所述第一侧壁326包括第一竖直侧壁321和第一弯曲侧壁322，所述第一弯曲侧壁322连接所述第一底部323和所述第一竖直侧壁321，所述第一底部323与所述绑定区106连接，所述弯曲区105与所述第一弯曲侧壁322连接，所述第一竖直侧壁321与所述盖板20的连接部分的宽度L小于0.5毫米。在其他实施方案中，绑定部32也可以仅包括第一竖直侧壁321和第一底部323，所述第一竖直侧壁321与所述第一底部323连接。
进一步，所述第一弯曲侧壁322的形状和尺寸与所述弯曲区105的第一弯曲部的侧壁的内侧的形状和尺寸相同，所述第一弯曲部为所述弧形顶点Q到所述绑定区106之间的部分；这样，所述弯曲区105可以以最大的面积与所述绑定部32接触，从而增大了所述绑定部32与所述显示面板10之间的连接面积，提高了所述中框30与所述显示面板10之间的连接强度，同时增强了所述绑定部32对所述显示面板10的容纳和支撑保护效果；所述第一竖直侧壁321和第一弯曲侧壁322的连接位置与所述弧形顶点Q接触，所述弧形顶点Q与所述绑定部32的第一侧壁326相切，消除了所述显示面板10的侧边与所述绑定部32之间的间隙，进一步减小了所述显示模组的边框。所述绑定部32的长度比所述绑定区106的长度大0.5毫米-1毫米，亦即，所述第一竖直侧壁321和所述第一弯曲侧壁322的长度比所述显示面板10的所述弯曲区105的长度大0.5毫米-1毫米，从而保证所述弯曲区105能够安全的容纳于所述绑定部32内，所述绑定部32的长度和所述弯曲区105的长度为平行于所述弯曲区105的弯曲轴线方向上的尺寸大小。如图3所示，中框30包括四个平直侧边和四个圆角区域，所述平直侧边和所述圆角区域形成环形中框。所述绑定部32可以仅设置于所述中框30的平直侧边上，也可以延伸至所述中框30的圆角区域，如图4所示，具体可根据所述显示面板10的弯曲区105和绑定区106的长度尺寸进行设定。
所述第一底部323还包括突出部324，所述突出部324突出于所述中框30的侧壁320，但不超过所述胶层114，所述突出部324的长度小于所述第一弯曲侧壁322的长度但大于所述绑定区106的长度，所述长度为平行于所述弯曲区105的弯曲轴线方向上的尺寸大小，所述突出部324与所述绑定区106连接，用于支撑所述显示面板10，保护所述绑定区106，同时不影响所述绑定区106与所述显示面板10的绑定效果。所述第一竖直侧壁321的顶面不高于所述显示面板10的出光面。
同样的，所述侧边部33可以包括第二侧壁(未在图中示出)和第二底部(未在图中示出)，所述第二侧壁包括第二竖直侧壁(未在图中示出)和第二弯曲侧壁(未在图中示出)，也可以仅包括第二竖直侧壁和第二底部，或第二弯曲侧壁和第二底部。同样的，所述显示面板10的侧边与对应的所述侧边部33的所述第二侧壁接触且相切，这样，减小了所述显示面板10与所述侧边部33之间的间隙，减小了所述显示模组的边框。
由于所述电路基板111靠近所述弯曲区105的侧边突出于所述膜层结构112靠近所述弯曲区105的侧边，且所述弯曲区105向所述显示面板10的背光面弯曲，因此，所述显示面板10、所述盖板20和所述中框30之间存在第一模组间隙101。在一种实施方案中，所述显示面板10的侧壁16与所述中框30的侧壁320接触连接，则所述第一模组间隙101为所述显示面板10的侧壁16、所述中框30的侧壁320和所述盖板20三者围成的空隙；在另一种实施方案中，所述显示面板10的侧壁16与所述中框30的侧壁320不接触，则所述第一模组间隙101为所述显示面板10的侧壁16、所述盖板20、以及所述绑定部32的第一侧壁326和第一底部323围成的空隙。同样的，所述侧边部33与所述显示面板10、所述盖板20三者之间也可围成所述第一模组间隙101。
所述填胶40填充于所述第一模组间隙101，连接所述显示面板10、所述盖板20和所述中框30，从而进一步增大了所述中框与所述显示面板10、所述盖板20之间的连接面积，提高了所述中框30与所述显示面板10、所述盖板20之间的粘着力和连接强度，同时提高了所述盖板的抗拉性能。为了保证所述中框30与所述盖板20、所述显示面板10之间的连接效果，所述盖板20与所述中框30的连接部分和所述盖板20与所述填胶40的连接部分的宽度之和D大于1毫米。相应的，所述绑定部32的第一侧壁326上设有注胶孔325，所述注胶孔325连通所述第一模组间隙101，用于向所述第一模组间隙101内注入所述填胶40，所述注胶孔325均匀地分散于所述绑定部32的第一侧壁326上，从而保证所述第一模组间隙101内所述填胶40的均匀性。所述填胶40的材料包括但不限于环氧树脂、热熔胶、热固胶等100℃以下成型或固化收缩率小的材料。
进一步，当所述显示面板10的侧壁16与所述中框30的侧壁320接触连接，且所述显示面板10的侧壁16、所述中框30的侧壁320、所述中框30的底部三者围成第二模组间隙（未在图中示出）时，所述填胶40还填充于所述第二模组间隙。同样的，所述中框30的侧壁320上设有对应于所述第二模组间隙的注胶孔。这样，所述填胶40更进一步增大了所述中框30与所述显示面板10之间的连接面积，提高了所述中框30与所述显示面板10之间的粘着力和连接强度。
所述显示模组还包括支撑件50，所述支撑件50位于所述平面区104和所述弯曲区105之间，填充所述平面区104和所述弯曲区105之间的面板间隙102，用于支撑所述弯曲区105，避免所述填胶40注胶过程中造成所述弯曲区105变形或所述电路层113发生断线等损伤。所述支撑件50的形状和尺寸与所述弯曲区105或所述面板间隙102的形状和尺寸相适应，只要能够起到支撑所述弯曲区105的作用即为本申请保护的内容，具体不做限定。所述支撑件50的材料包括但不限于环氧树脂、热熔胶、热固胶等100℃以下成型或固化收缩率小的材料。
