为了更清楚地说明本发明实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例，而非对本发明的限制。

图2是图1所示的显示装置中显示部件的示意图；
图3是图1所示的显示装置在显示模式下的示意图；

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供了一种显示装置，该显示装置包括显示部件，该显示部件包括液晶面板和背光源，所述液晶面板包括液晶盒、位于所述液晶盒靠近所述背光源一侧的第一偏光片以及位于所述液晶盒远离所述背光源一侧的第二偏光片，其中，所述第一偏光片和第二偏光片中至少一个为可活动的。
例如，本发明实施例中的显示装置可以为可穿戴式设备，例如智能手表，图1示出了根据本发明实施例的显示装置。如图1所示，该显示装置包括显示部件1以及穿戴部件2(例如，表带)，显示部件1设置在穿戴部件2上。如图2所示，显示部件1包括背光源11和液晶面板；液晶面板包括由对向基板15、液晶层14、阵列基板13构成的液晶盒、位于所述液晶盒靠近所述背光源11一侧的第一偏光片12以及位于所述液晶盒远离所述背光源1一侧的第二偏光片16。例如，该第二偏光片16是可活动的。进一步地，该第二偏光片16可绕自身几何中心水平旋转。或者，该第一偏光片12是可活动的。进一步地，该第一偏光片12可绕自身几何中心水平旋转。
例如，第一偏光片12和第二偏光片16可以为圆形或者方形。例如，可增设透明盖板17，并将该第二偏光片16贴附至该透明盖板17，通过旋转该透明盖板17带动第二偏光片16旋转。第二偏光片16可贴附至透明盖板17的上下任意一侧。为了实现对偏光片的保护，如图2所示，透明盖板17可设置在所述第二偏光片16远离所述液晶盒一侧。
在本发明实施例提供的显示装置中，通过旋转该显示装置的第二偏光片16，改变第二偏光片16的透光轴与第一偏光片12的透光轴的相对位置，进而可以改变液晶面板的亮度，实现照明功能。以图3所示的液晶面板(TN常白显示模式)为例，当用于显示图像时，第一偏光片12的透光轴与第二偏光片16的透光轴相互垂直，例如，第一偏光片12的透光轴为45度且第二偏光片16的透光轴为135度；在对向基板15与阵列基板13之间施加电压，液晶层14对光线进行调制以进行画面显示。若要将该显示装置转换为照明模式，如图4所示，可通过旋转第二偏光片16(例如，将第二偏光片16的透光轴旋转到45度)以使得第二偏光片16的透光轴与第一偏光片12的透光轴平行，使得透过第一偏光片12的偏振光能通过第二偏光片16射出，从而提高液晶面板的亮度，并实现照明功能。此外，上述液晶面板也可以为ADS 显示模式，其通过旋转偏光片改变液晶面板显示亮度的原理与上述TN显示模式相似，在此不再赘述。
通常，液晶面板中所有像素的亮度并不一致。因此在显示装置的使用过程中，为了在照明模式下获得较高的亮度，用户可缓慢旋转第二偏光片16并同时观察液晶面板的亮度变化，得到亮度较高时所对应的较佳旋转位置。为了便于用户记录该较佳旋转位置，如图1所示，还可以在穿戴部件2的表面上设置旋转标记21，在透明盖板17上设置指针171，并使旋转标记21均匀地分布在液晶面板的周边。当用户再次使用照明模式时，通过该旋转标记21和指针171，可直接旋转至记录的旋转位置。
在本发明实施例提供的显示装置中，显示部件中的偏光片设为可活动式结构。当用户被困特别是被困于黑暗环境下时，通过活动该偏光片，就可提高显示装置的亮度，实现照明功能，从而使得用户能够利用显示装置发出的光亮发出求救信号进行自救。
图5是本发明是实施例提供的另一种显示装置的示意图，该显示装置包括显示部件1以及穿戴部件2(例如，表带)。如图6所示，显示部件1包括背光源11和液晶面板；液晶面板包括由对向基板15、液晶层14、阵列基板13构成的液晶盒、位于所述液晶盒靠近所述背光源11一侧的第一偏光片12以及位于所述液晶盒远离所述背光源11一侧的第二偏光片16。例如，第一偏光片12、第二偏光片16以及液晶盒都为可活动的。例如，该可活动的方式为所述第一偏光片12、所述第二偏光片16、所述液晶盒构成的液晶面板可与背光源11分离。
例如，第二偏光片16还设置有用于保护第二偏光片16的透明盖板17；在此情形下，第一偏光片12、第二偏光片16、透明盖板17以及液晶盒都为可活动的。例如，该可活动的方式为所述第一偏光片12、所述第二偏光片16、透明盖板17、所述液晶盒构成的液晶面板可与背光源11分离。
例如，在本发明实施例的显示装置中，背光源11与液晶面板可通过螺旋连接方式结合，即在液晶面板与背光源11之一设置内螺纹结构，另一个设置与该内螺纹结构相匹配的外螺纹结构，液晶面板与背光源11通过该内螺纹结构与外螺纹结构实现结合或分离。例如，当将该显示装置由显示模式转换为照明模式时，只需通过扭转液晶面板的透明盖板17带动整个液晶面板旋转， 从而实现液晶面板与背光源11的分离。如图7所示，当液晶面板与背光源11完全分离后，背光源11完全裸露，从而实现照明功能。相比上述通过旋转偏光片实现照明模式的方式，由于将液晶面板与背光源11完全分离，直接采用背光源11进行照明，能够大大提高照明的亮度。
例如，参见图6及图7，所述显示装置的穿戴部件2上还设置有固定结构22，例如可以为卡扣。当所述液晶面板与背光源11分离时，通过该固定结构22可将液晶面板固定在穿戴部件2上，从而防止丢失或随意活动。
液晶面板与背光源还可以采用其他连接方式。例如，液晶面板与背光源可通过铰链连接，液晶面板可通过围绕铰链转动实现与所述背光源结合或分离。例如，还可以在液晶面板与背光源11之一设置滑轨，另一个设置为可在该滑轨上滑动的滑块，液晶面板与背光源11可通过该滑轨与滑块实现结合或分离。
以上所述仅是本发明的示范性实施例，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
