Description

显示装置壳体及显示装置 技术领域
本发明涉及显示技术领域，特别涉及一种显示装置壳体及显示装置。
背景技术
曲面显示装置随着显示技术的发展，已逐渐兴起并开始出现在消费市场中。向内弯曲的曲面屏幕更加贴合人类眼球的生理构造，由屏幕弯曲而形成的视觉景深空间将令画面层次更显真实丰富，可提升视觉代入感；而且曲面屏能有效减少屏幕两侧边缘画面到人眼的距离与屏幕中间部分的画面到人眼的距离之间的差异，从而获得更加均衡的图像，实现视野范围的提升。
曲面显示装置在一些特定使用场合需要调整显示面板的曲率，如在观看者人数较多时，处于偏离曲面球心或者偏离曲面中轴垂面位置的观看者的视角左右不对称，导致其观看效果下降，此时需要减小显示面板的弯曲程度、甚至恢复成平板状态，以保证观看效果。
现有技术中，曲率可调节的曲面显示装置常采用设置于其背板上的调节机构进行显示面板的曲率调节，调节机构可在背板两端施力使背板弯曲，通过改变调节机构的施力大小可盖板背板的曲率大小，从而使背板带动显示面板产生弯曲形变，以实现显示面板的曲率调节。
通常地，调节机构在进行显示面板的曲率调节后，还起到保持显示面板弯曲形状的作用，但是受背板和显示面板自身的变形特性等因素影响，背板和显示面板由调节机构所保持的曲面形状与适合观看的曲面形状不符，降低了显示装置的观看效果。

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。本发明也可以其他不同形式实现，因此本文阐述的实施例不应当被解释为本发明的限制.提供这些实施例是为了使本领域技术人员能够充分和完全的理解本发明的构思。
参见图1-图5所示，本发明具体实施方式提供了一种显示装置的壳体10。该壳体10包括背板11和至少一个曲率保持单元12。图2为背板11未发生形变时的结构示意图，图4为背板11发生形变时的结构示意图。背板11被构造或配置成在发生形变时可改变其曲率；并且优选地，背板11在受外力作用时产生弹性形变，且可在所述外力撤除之后可依靠自身弹性恢复至形变前的形状。所述至少一个曲率保持单元12位于背板11弯曲时凸起一侧，并且每个曲率保持单元12包括至少一排支撑件121。所述一排支撑件121的延伸方向与背板11的弯曲时所绕的轴线方向垂直。
图5为单个支撑件121在背板11后侧可能具有的状态的示意图，其中实线部分示出了处于支撑状态的支撑件，虚线部分示出了处于非支撑状态的支撑件。结合图1-6所示，每个支撑件121的第一侧边1211通过铰接轴122活动安装于背板11，且可绕铰接轴122沿图5中箭头方向在实线所示的支撑状态与虚线所示的非支撑状态之间运动。当支撑件121处于支撑状态时，其基本上与背板11垂直，而当支撑件121处于非支撑状态时，其在重力作用下垂下。在具体操作时，当需要将显示装置(或显示装置的壳体)弯曲时，可手动或通过其他工具或机构将曲率保持单元12的各个支撑件调整到支撑状态。具体地，通过弯曲背板11，使曲率保持单元12中相邻的两个支撑件121的侧面相互抵接。当将背板弯曲到位之后，每个支撑件121都与其相邻的支撑件的侧面抵接，从 而能够防止背板恢复到其未弯曲的平面状态。而需要将背板恢复到其平面状态时，可通过手动或其他工具或机构使得曲率保持单元12中的相邻支撑件的侧面错开，从而曲率保持单元12无法向背板提供弯曲支撑力，使得背板能够恢复到其平面状态。
如图1和图2所示，背板11处于平面状态时，背板11未发生形变，各曲率保持单元12处于非支撑状态，此时每个支撑件121可均在重力作用下自然下垂，或者在其他实施例中，这些支撑件可以通过其他机构保持成与背板11基本贴合或与相邻的支撑件贴合的状态。每相邻两个支撑件121之间相向的两个侧边不相抵，并且由于其具体形状，相邻的支撑件121的侧部相互搭接。这将在下文中详细说明。可以理解的是，背板11可以采用能够发生弹性形变的材料制作，以便于在曲率保持单元12从支撑状态变为非支撑状态时，可以更方便的恢复未发生形变的状态。
如图3和图4所示，背板11在受到外力作用处于弯曲状态时，曲率保持单元12处于支撑状态，且处于支撑状态的曲率保持单元12的每排支撑件121中的每个支撑件121均与背板11垂直，且每相邻的两个支撑件121相向的两个侧边相抵，此时多个支撑件121呈曲线状排列，以使背板11的弯曲形状固定。
因该曲率保持单元12通过多个支撑件121抵消背板11弯曲时的回弹力，与现有技术中在背板11两端施力使背板11弯曲变形的方式相比，曲率保持单元12中的多个支撑件121为背板11提供的力较为均匀，可使背板11产生较为规则的曲面形状，以保持适合观看的曲面形状。
如图6所示的支撑件的实施例中，每个支撑件121具有板状结构，且支撑件121具有第一侧边1211、第二侧边1212以及第一斜边1213和第二斜边1214，第一侧边1211与第二侧边1212相对设置、且第二侧边1212的长度大于第一侧边1211的长度，支撑件121的第一侧边1211安装于背板11，第一斜边1213用于连接第一侧边1211的一端与第二侧边1212的一端，第二斜边1214用于 连接第一侧边1211的另一端与第二侧边1212的另一端。
优选地，为便于加工制备，如图6所示，每一个支撑件121中，第一斜边1213和第二斜边1214沿第一侧边1211朝向第二侧边1212方向延伸的中心线对称分布，且沿由第一侧边1211朝向第二侧边1212的方向，第一斜边1213和第二斜边1214与中心线之间的距离逐渐增大。
优选地，如图6所示，支撑件121为等腰梯形的平板结构。参见图4，多个等腰梯形结构的支撑件121依次排列且每相邻两个支撑件121之间的斜边相抵时，曲率保持单元12呈曲线状分布。
支撑件121的结构除图6所示结构外，还可为扇环状结构。
在示例性的实施例中，每个曲率保持单元12中，每个支撑件121的第一侧边1211铰接于背板11，铰接装置的枢转轴线可与曲率保持单元12的延伸方向一致。
在示例性的实施例中，为提高支撑件121的强度，支撑件121由玻璃、金属、碳纤维复合材料、有机玻璃等材料制备，同时，为提高背板11的强度，背板11也可由玻璃、金属、碳纤维、有机玻璃等材料制备。
在示例性的实施例中，支撑件121的厚度为背板11的厚度的0.5-10倍，如0.5倍、1倍、2倍、3倍、5倍、8倍、10倍。
在另一实施例中，背板11上还可设置有多个曲率保持单元12。如图7所示，背板11上可安装有三个平行分布的曲率保持单元12，且每个曲率保持单元12中的支撑件121的排列方向均水平。根据实际需求，曲率保持单元12的数量还可多于或少于三个。此外，多个曲率保持单元也可以布置在同一水平高度，彼此之间隔开一定距离。例如，背板的左侧设有一个或多个曲率保持单元，背板的右侧也设有一个或多个曲率保持单元，从而背板的左侧和右侧可以独立地进行弯曲调节和支撑，如图8所示。
在上述三个曲率保持单元12中，为提高背板11在曲率保持单元处于支撑状态时受力的均匀度，每个曲率保持单元12在处于支撑状态时使背板11保持 的弯曲形状的曲率均相同；
此外，为使背板11保持不同的弯曲曲率，在三个曲率保持单元12中，至少一个曲率保持单元12在处于支撑状态时使背板11保持的弯曲形状的曲率与其他曲率保持单元12在处于支撑状态时使背板11保持的弯曲形状的曲率不同，优选地，该曲率保持单元12为位于背板11中间。
在通常情况下，如图3-4所示，背板为矩形，在背板11竖直地支撑显示面板，并且背板绕竖直的弯曲轴线弯曲形变，并且因此支撑件121的排列方向为水平方向。
在特殊情况下，如果需要，也可以将支撑件121设置成沿非水平方向延伸。例如，如图9所示的实施例中，曲率保持单元12中的支撑件121的排列方向与水平方向成一角度，此时背板11的弯曲时所绕的轴线为非竖直方向。
本发明具体实施方式还提供了一种显示装置，包括柔性显示面板，显示面板可在外力作用下发生弹性形变以改变其曲率，该显示面板可为液晶显示面板或OLED显示面板，优选为OLED显示面板，还包括上述的显示装置壳体10，显示面板安装于背板11背离曲率保持单元的一侧。
该显示装置中的显示面板的曲率可在显示装置壳体10中的背板11的曲率发生变化时随之改变，且其曲率可在显示装置壳体10中的曲率保持单元处于支撑状态时保持固定，以适用于多种不同的使用场合，且当显示面板处于弯曲状态时，至少一个曲率保持单元12可处于支撑状态，以使显示面板保持弯曲形状。
因该曲率保持单元12通过多个支撑件121抵消显示面板弯曲时的回弹力，与现有技术中在显示面板两端施力使显示面板弯曲变形的方式相比，曲率保持单元12中的多个支撑件121为显示面板提供的力较为均匀，可使显示面板产生较为规则的曲面形状，以保持适合观看的曲面形状。
尽管已经结合附图示出并描述了多个示例性的实施例，但本领域的技术人员将会认识到，可以对本发明实施例进行各种改动和变型而不脱离本发明的精 神和范围。因此，本发明的范围应由所附权利要求及其等同技术方案限定。
