本实施例的显示装置包括显示面板104和模组构件，所述模组构件与所述显示面板104组合为一体。其中，所述模组构件包括背板101、加热组件102和热膨胀组件103。
所述加热组件102固定于所述背板101的第一表面上，所述第一表面为所述背板101的外表面，即，所述第一表面为背向所述显示面板104的一面，所述背板101的第二表面（内表面）朝向所述显示面板104。
所述加热组件102覆盖所述第一表面的一部分或全部。在本实施例中，以所述加热组件102覆盖所述第一表面的一部分来举例说明。
在本实施例中，所述加热组件102包括第一加热组件1021和第二加热组件1022，所述第一加热组件1021和所述第二加热组件1022平行设置。所述第一加热组件1021所在的直线与第一方向平行，其中，所述第一方向平行于所述显示面板104的长边。
在本实施例中，所述热膨胀组件103与所述第一表面具有预定距离S。具体地，所述加热组件102为板状，所述加热组件102具有一厚度，所述厚度与所述预定距离对应。所述第一加热组件1021和所述第二加热组件1022包括加热丝或加热块等器件。
所述热膨胀组件103固定于所述加热组件102上，所述热膨胀组件103可以通过粘接或焊接的方式固定于所述加热组件102上，所述热膨胀组件103还可以通过螺钉固定于所述加热组件102上。具体地，所述热膨胀组件103包括第一热膨胀组件1031和第二热膨胀组件1032，所述第一热膨胀组件1031固定于所述第一加热组件1021上，所述第二热膨胀组件1032固定于所述第二加热组件1022上。
所述热膨胀组件103具有第一热膨胀系数。其中，所述加热组件102用于为所述热膨胀组件103提供热量，所述热膨胀组件103用于根据所述加热组件102所提供的热量产生第一形变，并用于向所述背板101施加第一作用力，以使所述背板101产生第二形变，所述第一作用力是所述热膨胀组件103将所述加热组件102所提供的热量转换得到的。
具体地，所述第一热膨胀组件1031用于在接收到所述加热组件102所产生的热量后，沿所述第一方向（所述第一热膨胀组件1031的长度方向）膨胀，从而产生所述第一形变，并迫使所述背板101弯曲（产生所述第二形变），所述第二热膨胀组件1032用于在接收到所述加热组件102所产生的热量后，沿所述第一方向（所述第二热膨胀组件1032的长度方向）膨胀，从而产生所述第一形变，并迫使所述背板101弯曲（产生所述第二形变）。
所述模组构件用于在所述背板101产生所述第二形变时向所述显示面板104施加第二作用力，以使所述显示面板104产生第三形变。优选地，在本实施例中，所述显示面板104为可挠性面板，即，所述显示面板104为在受力的情况下可弯曲的面板。所述第二形变和所述第三形变均与沿第三方向弯曲对应，其中，所述第三方向为从所述背板101的第一表面指向所述第二表面的方向。
在本实施例中，所述背板101包括第一板体，即，所述背板101为一块单一的板体（由同一热膨胀系数所对应的材料构成），所述第一板体具有第二热膨胀系数。所述第二热膨胀系数小于所述第一热膨胀系数，其中，所述第二热膨胀系数小于所述第一热膨胀系数对应所述背板101的受热膨胀速度小于所述热膨胀组件103的受热膨胀速度。
在本实施例中，所述显示装置还可以包括温度控制器，所述温度控制器与所述加热组件102连接，所述温度控制器用于控制所述加热组件102开启或关闭，以及用于控制所述加热组件102所产生的热量的大小。
进一步地，所述显示装置还可以包括温度传感器，所述温度传感器用于感测（测量）所述加热装置或所述热膨胀组件103的温度，所述温度传感器还用于将所感测到的温度数据发送给所述温度控制器，以使得所述温度控制器对所述加热组件102所产生的热量进行控制。
进一步地，所述温度控制器还用于根据用户的操作指令对所述加热组件102所产生的热量进行控制。
在获取到所述加热组件102所提供的热量后，所述热膨胀组件103随温度的变化在其长度方向上的膨胀量△L=f（△t），其中，△t为温度变化量。
假设所述热膨胀组件103从常温升温△t后，所述背板101长度为L1，支架长为L2，则△L =L2-L1= f（△t）=θ*△H，因此，θ= f（△t）/△H，所述背板101的曲率半径R1=L1/θ=L1*θ/ f（△t）。
因此，通过控制所述加热组件102的所产生的热量，即可控制所述温度变化量△t，从而可以控制所述背板101的第二形变的曲率半径。
通过上述技术方案，可以使得所述显示面板104根据实际需要弯曲（产生形变），从而形成所需的多种曲面显示效果。
参考图5、图6、图7和图8，图5为本发明的显示装置的第二实施例的等轴测图，图6为图5所示的显示装置的爆炸视图，图7为图5所示的显示装置处于形变状态下的等轴测图，图8为图5所示的显示装置处于形变状态下的爆炸视图。
本实施例与上述第一实施例相似，不同之处在于：
在本实施例中，所述第一加热组件1021和所述第二加热组件1022所在的直线（长度方向）与第二方向平行，其中，所述第二方向平行于所述显示面板104的短边。
所述第一热膨胀组件1031用于在接收到所述加热组件102所产生的热量后，沿所述第二方向（所述第一热膨胀组件1031的长度方向）膨胀，从而产生所述第一形变，并迫使所述背板101弯曲（产生所述第二形变），所述第二热膨胀组件1032用于在接收到所述加热组件102所产生的热量后，沿所述第二方向（所述第二热膨胀组件1032的长度方向）膨胀，从而产生所述第一形变，并迫使所述背板101弯曲（产生所述第二形变）。
本发明的显示装置的第三实施例与上述第一实施例或第二实施例相似，不同之处在于：
在本实施例中，所述背板101包括第二板体和第三板体。所述第二板体和所述第三板体叠加组合为一体。
其中，所述第二板体具有第三热膨胀系数，所述第三板体具有第四热膨胀系数。所述第三热膨胀系数和所述第四热膨胀系数均小于所述第一热膨胀系数。
本发明的显示装置的第四实施例与上述第三实施例相似，不同之处在于：
所述第二板体和所述第三板体拼接为一体，所述第一加热组件1021设置于所述第二板体上，所述第二加热组件1022设置于所述第三板体上。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
