具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
实施例一
如图1所示，本发明提供了一种显示装置，所述显示装置包括第一基板1和第二基板2，所述第一基板1和所述第二基板2对盒形成显示面板I；
在所述显示面板I任一表面设置形变层32，所述形变层32用于在达到第一形变温度时带动所述显示面板I发生第一形变，使所述显示装置呈曲面显 示。
如图1所示，所述显示面板I任一表面是指显示面板I外露的表面，即第一基板的第一表面11或第二基板的第一表面21。其中，第一基板的第一表面11是指远离第二基板2的表面，第二基板的第一表面21是指远离第一基板1的表面。
如本领域普通技术人员所知，显示面板I由彩膜基板和阵列基板组成。显示面板I中面向观看者的基板为彩膜基板，同时显示面板I中另一块基板是阵列基板。
本实施例中，显示面板I由第一基板1和第二基板2组成。本领域普通技术人员可以理解，第一基板1和第二基板2是一个相对概念。其中，第一基板1可以是彩膜基板，第一基板1也可以是阵列基板。与此相对，第二基板2可以是阵列基板，第二基板2也可以是彩膜基板。如果定义了第一基板1，则显示面板I中的另一块基板是第二基板2。
在本发明图1、图2、图3及图4所示实施例中均将设有形变层32的基板定义为第一基板1。
更具体地，如图1所示，本实施例中，所述显示面板I将最上面的表面定义为显示面，即面对观看者的表面为显示面。在本实施例中第二基板2是面向观看者的，故第二基板2是彩膜基板，第一基板1是阵列基板。其中，上和下均为相对概念，以图1为例，本实施例中的上和下均是以读者看到的图形方向定义的上和下。
依此类推，如图2所示，第一基板1是彩膜基板，第二基板2是阵列基板。
依此类推，如图3所示，第二基板2是彩膜基板，第一基板1是阵列基板。
依此类推，如图4所示，第一基板1是彩膜基板，第二基板2是阵列基板。
本实施例中，所述第一形变指所述显示装置由平面显示变为曲面显示。
如图1A所示，所谓曲面显示是指所述显示面板I呈符合人体眼球曲面特 征的弯曲。当观看者眼球位于最佳观看点时(曲面显示的曲率中心)，所述显示面板I中各点距离观看者眼球的距离相等。
如图1所示，本发明在所述显示面板I的任一表面设置所述形变层32，当所述形变层32达到第一形变温度时其产生第一形变，并且对所述显示面板I产生内力。由于所述显示面板I自身尺寸不变，如图1A所示，内力会迫使所述显示面板I弯曲，进而使所述显示装置呈曲面显示。可见，本发明所述的显示面板I通过自身产生的内力被弯曲，且本发明所述的显示装置在持续的内力作用下可一直保持弯曲。因此，本发明无需使用现有技术中背光组件的护壳来固定形状，从而降低了装配难度。
此外，由于本发明通过在显示面板I任一表面设置形变层32达到曲面显示效果，且无需使用现有技术中背光组件的护壳来固定形状，因此提高了显示面板II的集成度。
此外，由于本发明通过在显示面板I任一表面设置形变层32达到曲面显示效果，且无需使用现有技术中背光组件的护壳来固定形状，使得本发明所述的显示装置可应用于无需背光组件的透明显示装置中，从而拓宽了本发明所述显示装置的应用范围。
此外，由于本发明通过在显示面板I任一表面设置形变层32达到曲面显示效果，且无需使用现有技术中背光组件的护壳来固定形状，因此本发明所述的显示装置能够实现轻薄化。
如图3所示，本实施例中，所述形变层32采用电控形变记忆材料制成。所述形变层32通过自身导电产生的热量达到所述第一形变温度。更具体地，所述形变层32设置在第一基板的第一表面11即阵列基板的第一表面。
如图3所示，本实施例通过形变层32自身导电产生的热量达到所述第一形变温度，还能够减少所述显示装置对自身工作温度的影响。
如图3所示，更具体地，本实施例中，所述形变层32所采用的电控形状记忆材料为市售材料。电控形变记忆材料具体可以是在形变记忆聚合物(英文Shape Memory Polymers，简称SMP)中掺杂导电碳黑、金属粉末或导电聚合物的材料。
如图3所示，本实施例中，形变层32达到第一形变温度具体是指达到电控形变记忆材料的记忆温度。
更具体地，本实施例中，考虑到所述显示装置的工作温度，第一形变温度通常设置在80度至90度之间。当然，本领域普通技术人员可以理解，第一形变温度不局限于此，还可以是能满足发明的设计要求的其他温度。
如图3所示，具体地，本实施例中所述显示面板I还包括驱动电路(未示出)，所述形变层32与所述驱动电路(未示出)相连。
如本领域普通技术人员所知，所述显示装置通过所述驱动电路(未示出)控制所述显示面板I的显示，并且所述驱动电路(未示出)的主要功能是实现在显示时序信号控制下显示数据信号的格式转换输出。所述形变层32通过所述驱动电路输入高电平实现所述形变层32的导电。
如图4所示，本实施例与图3所示实施例的区别仅在于，所述形变层32设置在第一基板的第一表面11的含义不同。本实施例中，第一基板的第一表面11指的是彩膜基板的第一表面。
如图1所示，具体地，本实施例中所述形变层32由热控形变记忆材料制成。所述显示装置还包括导电层31，所述导电层31及所述形变层32按照由内至外的顺序叠加在所述显示面板I任一表面。所述形变层32通过所述导电层31导电产生的热量达到所述第一形变温度。
本实施例的结构简单易于实现。
当然，本领域普通技术人员可以理解，所述导电层31及所述形变层32还可以按照由外至内的顺序叠加在所述显示面板I任一表面。
如图1所示，更具体地，本实例中所述显示面板I任一表面具体指第一基板的第一表面11，即阵列基板的第一表面。其中，本实施例中以相对所述第一基板的第一表面11的近远程度定义内、外概念。靠近所述第一基板的第一表面11的结构层定义为内，远离所述第一基板的第一表面11的结构层定义为外。
如图1所示，更具体地，本实施例中所述导电层31及形变层32设置在所述第一基板的第一表面11(即所述阵列基板的第一表面)。
如图1所示，更具体地，本实施例中，所述形变层32所采用的热控形状记忆材料是市售材料。热控形状记忆材料具体可以是形变记忆聚合物(英文Shape Memory Polymers，简称SMP)。
其中，形变层32达到第一形变温度是指达到热控形变记忆材料记忆温度。
具体地，考虑到所述显示装置的工作温度，本实施例中第一形变温度通常设置在80度至90度之间。当然，本领域普通技术人员可以理解，第一形变温度不局限于此，还可以是能满足发明的设计要求的其他温度。
如图1所示，更具体地，本实施例中所述导电层31为透明导电层，用以此透过光线。所述形变层32通过自身结构或自身材质透过光线。
如图1所示，更具体地，本实施例中所述显示面板I还包括驱动电路，所述导电层31与所述驱动电路相连。
如本领域普通技术人员所知，所述显示装置通过所述驱动电路(未示出)控制所述显示面板I的显示，所述驱动电路(未示出)的主要功能是实现在显示时序信号控制下显示数据信号的格式转换输出。所述形变层32通过所述驱动电路输入高电平实现所述导电层31的导电。
如图2所示，本实施例中与图1所示实施例的区别在于，本实施例中，所述导电层31及形变层32设置在所述第一基板的第一表面11的含义不同。本实施例中，所述第一基板的第一表面11指的是所述彩膜基板的第一表面。
如图1所示(或图2或图3或图4所示)，具体地，当所述形变层32由所述第一形变温度恢复到第二形变温度时带动所述显示面板I发生第二形变，从而使所述显示装置恢复平面显示。
其中，第二形变温度通常指20度-25度的常温。所述第二形变指所述显示装置由曲面显示变为平面显示。
如图1所示，本发明工作过程以图1所示显示装置为例加以说明。所述显示装置呈开机状态，所述显示面板I呈平面显示，所述显示装置呈平面显示，
当所述导电层31导电时，使所述形变层32达到第一形变温度(80度-90 度)并且所述形变层32发生第一形变，从而实现所述显示装置的平曲显示转换。即，所述显示装置具有平曲显示转换功能；
当所述导电层31断电时，所述形变层32由所述第一形变温度(80度-90度)恢复到第二形变温度(20度-25度)并且所述形变层32发生第二变形，从而使所述显示面板I恢复平面显示，实现所述显示装置的曲平显示转换。即所述显示装置具有曲平显示转换功能；
当所述显示装置呈开机状态时，所述导电层31不通电，所述形变层32无变化，从而所述显示面板I为平面显示，所述显示装置为平面显示，即所述显示装置具有单纯平面显示功能。
发明人在实现本发明过程中发现，由于现有技术中的显示面板I和背光组件都是弯曲的，且它们弯曲的形状是固定的，所以现有技术中的曲面电视只能呈固有的曲面显示状态。发明人还发现现有技术中的曲面电视的曲率有两种形式。形式一：固有曲率，指曲面电视的曲率是固定唯一的，相应的，曲面电视的最佳观看点是唯一的，最佳观看点就是曲面电视的曲率中心；形式二，可调曲率，指曲面电视的曲率远近可调，一旦调节完毕，曲面电视的最佳观看点也是固定的，即最佳观看点为调节后曲率中心。由此可见，无论采用哪种方式，曲面电视的最佳观看点只有一个，在单人观看时效果较好。但是，当多人观看时由于曲面电视无法具备适应多人观看的多个最佳观看点，反而达不到理想的观看效果，存在观看不灵活的问题。
如图1所示，相比上述现有技术，本发明在显示面板I任一表面设置形变层32，并且通过形变层32达到第一形变温度发生第一形变，实现所述显示装置的平曲显示转换；通过形变层32达到第二形变温度发生第二形变，实现所述显示装置的曲平显示转换；所述显示装置开机，所述显示装置呈平面显示状态。即本发明所述显示装置具有曲平显示转换功能，或平曲显示转换功能，或单纯的平面显示功能。单人观看时利用所述显示装置的平曲显示转换功能，切换所述显示装置为曲面显示状态；多人观看时，所述显示装置呈单纯平面显示状态，或利用所述显示装置的曲平显示转换功能，切换所述显示装置为平面显示状态。如此显示装置不但适合单人观看且适合多人观看， 具有观看灵活性，具有用户体验好的优点。
此外，本发明通过在显示面板I上设置形变层32的结构，实现所述显示装置观看过程的平曲或曲平转换。因此，显示装置对应的背板结构不用设计为弯曲结构，使得所述显示装置既可以放置在桌面上，还可以悬挂放置，从而具有布置灵活性。
此外，本发明通过在显示面板I上设置形变层32的结构，实现所述显示装置观看过程的平曲或曲平转换。所述显示装置在不观看时保持平面显示，因此具有美观方便的优点。
此外，本发明通过在显示面板I上设置形变层32的结构，实现所述显示装置观看过程的平曲或曲平转换。因此所述显示装置在不观看时保持平面显示，使得本发明所述显示装置以平面结构形式运输。在运输过程遇到颠簸时，其能减少磕碰，增加了产品安全性能。
图2表示实施例中所述显示装置的平曲显示转换或曲平显示转换或纯平面显示原理。与图1所示实施例的显示原理相同，针对所述显示装置转换原理，本部分不再赘述。
图3或图4表示实施例中所述显示装置的平曲显示转换或曲平显示转换或纯平面显示原理。与图1所示实施例显示原理基本相同，针对所述显示装置转换原理，本部分不再赘述。
如图5所示，还可参见图6，本实施例以图5为主加以说明。本实施例中，所述形变层32为网格，所述网格包括多个Y向线段322和多个X向线段321。所述多个Y向线段322呈纵向平行叠加排列，所述多个Y向线段322中的每个Y向线段322均为直线，所述多个X向线段321呈横向平行叠加排列，所述多个X向线段321中的每个X向线段321均设有预设形状(参见图6中321)。本实施例，结构简单易于实现。
其中，本实施例中的X向及Y向均为相对概念。本实施例中的X向及Y向是以面对读者的平面定义的，其中，横向为X向，纵向为Y向。
如图6所示，本实施例所述形变层32未变形前的结构示意图，每个X向线段321变形前均为的预设形状即图示的波浪线，多个Y向线段322变形 前为直线。图6A表示本发明所述形变层32变形后的结构示意图，当形变层32达到第一形变温度后，多个Y向线段322在Y向不发生形变，即多个Y向线段322变形后也是直线，多个X向线段321中每个X向线段321变形后延展为直线。由于显示面板I外形尺寸不变，所以带动显示面板I发生弯曲，使所述显示装置呈曲面显示。
如图5所示，更具体地，本实施例中的所述形变层32结构，是以图1所示形变层为例加以说明的。具体地，形变层32设置在第一基板1即阵列基板上，形变层32的X向线段321未变形前为图6波浪线，形变层32的X向线段321变形后为图6A所示的直线，形变层32延展产生第一形变。
当然本领域普通技术人员可以理解，图5所示形变层32结构还可以应用在图2、图3或图4所示的实施例。当图5所示的形变层32结构应用在图2所述实施例时，形变层32收缩产生第一形变；当图5所示的形变层32结构应用在图3所述实施例时，形变层32延展产生第一形变；当图5所示的形变层32结构应用在图4所述实施例时，形变层32收缩产生第一形变。
如图5所示，本实施例中，所述形变层32为网格，所述网格空腔部分能够透光。因此，所述形变层32自身可以选透光材料，也可以选不透光材料。
本实施例中，如图6所示，所述每个X向线段321的预设形状为波浪线。本实施例采用上述结构，具有结构简单，易于实现的优点。
更具体地，如图6所示，本实施例中，所述每个X向线段321全部设置为所述预设形状。即所述每个X向线段321全部设置为波浪线。本实施例采用上述结构，具有结构简单，易于实现的优点。
更具体地，如图6所示，所述每个X向线段321全部设置为所述预设形状，且均匀设置。本实施例通过上述结构，使得形变均匀。
更具体地，如图6B所示，所述每个X向线段321全部设置为所述预设形状，且非均匀设置。本实施例中非均匀设置是指预设形状大小及密集程度的不均匀。所述每个X向线段321两端预设形状的形变量大(弯曲程度大)，即两端波浪线形状小且密集。所述每个X向线段321中间预设形状的形变量小(弯曲程度小)，即中间波浪线形状大且密集。
如图7所示，本实施例中，所述每个X向线段321局部设置为所述预设形状。所述每个X向线段321的预设形状相对其X向局部设置。本实施例通过上述结构，实现本发明快速形变。
更具体地，如图7所示，本实施例中，所述每个X向线段321的中间是直线、两端设置为所述预设形状。由于显示面板I的中部无需形变，所以本实施例通过上述结构，实现快速形变，能够快速形成曲面显示。
本实施例中，如图8所示，所述每个X向线段321的预设形状为山峰线。更具体地，本实施例中，所述每个X向线段321全部设置为山峰线。本实施例采用上述结构，具有结构简单，易于实现的优点。
本实施例中，如图9所示，所述每个X向线段321的预设形状为双曲线。更具体地，本实施例中，所述每个X向线段321全部设置为双曲线。本实施例采用上述结构，具有结构简单，易于实现的优点。
本实施例中，如图10所示，所述每个X向线段321的预设形状为矩形波。更具体地，本实施例中，所述每个X向线段321全部设置为矩形波。本实施例采用上述结构，具有结构简单，易于实现的优点。
当然本领域普通技术人员可以理解，参见图6，所述每个X向线段321的预设形状不局限于为波浪线、山峰线(参加图8)、双曲线(参加图9)或矩形波(参加图10)。所述每个X向线段321的预设形状还可以是其他形状，只要其能满足预设形状功能即可。此外，所述每个X向线段321的预设形状的形变量也可以根据显示面板I大小、曲率需求随意设计，只要其能满足X向线段321预设形状功能即可。
如图11所示，本实施例中，可选地，所述形变层32包括多个长孔323，所述多个长孔323呈规则排列，所述多个长孔323中的每个长孔323均相对Y向伸展。
本实施例中，所述形变层32选用透光材料。
本实施例中的X向、Y向及Y轴均为相对概念，本实施例中的X向、Y向及Y轴是以面对读者的平面定义的。其中，横向为X向，纵向为Y向，该平面的纵向轴线为Y轴。
如图12所示，本实施例中，所述形变层32达到第一形变温度，所述形变层32中多个长孔323发生形变，每个孔均向X方向延展，呈放大孔状(如图12所示323)。通过形变层32产生内力使显示面板I发生一定的曲率形变，实现本发明所述显示装置相对Y轴的弯曲，达到平曲显示转换目的。当形变层32达到第二形变温度，所述多个长孔323由图12所示形状恢复到图11所示形状。如图11所示，多个长孔323上在第二形变温度下恢复长孔323(图11所示)状态，最终达到曲平转换的目的。
当然本领域普通技术人员可以理解，如图11所示，本实施例中的所述形变层结构，既可以是图1所示实施例，还可以是图2、图3或图4所示实施例。
具体地，如图11所示，本实施例中，所述多个长孔323均为梭形孔。本实施例采用上述结构，具有结构简单，易于实现的优点。
具体地，如图13所示，本实施例中，所述多个长孔323均为长方形孔。本实施例采用上述结构，具有结构简单，易于实现的优点。
当然，本领域普通技术人员可以理解，参见图11，所述多个长孔323的形状不局限于梭形孔或长方形孔，所述多个长孔323还可以是其他形状，只要其能满足形变功能即可。
如图11所示，还可参见图13，本实施例中，所述多个长孔323相对所述形变层32的Y轴对称排列。本实施例采用上述结构，具有结构简单，易于实现的优点。
如图11所示，本实施例中，所述多个长孔323呈均匀排列。本实施例通过上述结构，使得本发明形变均匀。
如图13所示，本实施例中，所述多个长孔323呈非均匀排列。本实施例通过上述结构，实现本发明快速形变。
更具体地，如图13所示，本实施例中，所述多个长孔323按照中间稀疏、两端密集的规律排列。由于显示面板I的中部无需形变，所以本实施例通过上述结构，使得本发明快速形成曲面显示。
如图1所示，实施例中，所述形变层32延展发生所述第一形变。本实施 例中，形变层32在第二形变温度(20度-25度)下设有预设形状(图6中321)，且本实施例中的形变层32在第一形变温度(80度-90度)下发生第一形变，形变层32在第二形变温度(20度-25度)下发生第二形变。当然本领域普通技术人员可以理解，所述形变层32延展发生所述第一形变，还可以是图2、图3至图13任一附图所示实施例。以上第一形变温度也可以是20度-25度，第二形变温度也可以是80度-90度，或者可以是其他的温度。这些温度根据液晶、形变层或其他材料的性质及其制程温度范围等工艺条件而定。
当然本领域普通技术人员可以理解，参见图1，所述形变层32还可以收缩发生所述第一形变。本实施例与所述形变层32延展发生所述第一形变的区别，仅在于本实施例中的形变层32是在第一形变温度(80度-90度)下设有预设形状(图6中321)，且本实施例中的形变层32在第一形变温度(80度-90度)下发生第一形变(平转曲)，形变层32在第二形变温度(20度-25度)下发生第二形变(曲转平)。当然本领域普通技术人员可以理解，所述形变层32收缩发生所述第一形变，还可以是图2、图3至图13任一附图所示实施例。以上第一形变温度也可以是20度-25度，第二形变温度也可以是80度-90度，或者可以是其他的温度。这些温度根据液晶、形变层或其他材料的性质及其制程温度范围等工艺条件而定。
如图14所示，本实施例中，所述显示装置100还包括处理模块6，所述处理模块6根据曲率计算出所述形变层32的变形量、并根据所述变形量计算出所述第一形变温度。所述显示装置100根据此第一形变温度来进行温度调节，达到第一形变。
本实施例中，所述曲率可以为多个预设曲率，观看者从其中选取多个预设曲率中的一个预设曲率。通过所述处理模块6计算与所选预设曲率相对应的第一形变温度，使得所述形变层32产生第一形变，从而使所述显示装置100呈曲面显示并且所述曲面显示的曲率为所选预设曲率。通过重复上述操作，最终使得所述显示装置100实现不同曲率，即实现所述显示装置100曲率可调。
更具体地，本实施例所述处理模块6可应用在图1至图4任一种实施例 中。
进一步地，如图15所示，所述显示装置100还包括感应模块7和测距单元8，所述感应模块7经所述测距单元8连接所述处理模块6。所述感应模块7用于感应观看者位置；所述测距单元8用于获得观看者的距离L并将其转化成曲率值，例如，可以转化成适合此位置的观看者的最佳观看曲率的值。所述处理模块6根据此曲率计算出所述形变层32的变形量、并根据所述变形量计算出所述第一形变温度。
本实施例中，通过所述感应模块7感应观看者位置，通过所述测距单元8计算距离获得所述曲率，通过所述处理模块6计算出与所述曲率相对应的形变层32的变形量，并根据所述变形量计算出第一形变温度。所述显示装置100根据所述第一形变温度使得所述形变层32产生第一形变，使所述显示装置呈与所述曲率对应的曲面显示。观看者位于不同位置时，通过重复上述操作，最终使得所述显示装置100实现不同曲率，即实现所述显示装置100曲率可调，以使得不同位置的观看者能达到最佳观看效果，提高了观看位置的可变性。
更具体地，本实施例所述处理模块6可应用在图1至图4任一种实施例中。
如图1所示，具体地，第一基板1和第二基板2为树脂基板或玻璃基板，当然本领域普通技术人员可以理解，第一基板1和第二基板2不局限于树脂基板或玻璃基板，还可是其他材质，只要满足第一基板1和第二基板2的设计要求即可。
参见图1，具体地，本领域普通技术人员都知道，显示面板I还包括第一偏光膜4、第二偏光膜5。第一偏光膜4位于第一基板1上方，第二偏光膜5位于第二基板2下方。其中，上方、下方均为相对概念，以图1为例，本实施例中的上方和下方均以读者看到的图形方向定义上和下，进而定义上方和下方。
参见图1，更具体地，所述显示装置不局限于电视机，所述显示装置可以是液晶显示面板、OLED面板、手机、平板电脑、显示器、笔记本电脑、 数码相框、导航仪等任何具有显示功能的产品或部件。
参见图1，进一步地，当显示装置为手机、平板电脑、显示器、笔记本电脑等时，所述显示装置还包括背光组件。为了达到更好的显示效果，背光组件也具有曲平转换功能。在技术上，背光组件可以简单地利用有一定机械强度的聚合物类或合金类形变聚合物，通过注塑件或其它方法使背板组件与显示面板I有匹配的形变温度，从而与显示面板I同时形变。
实施例二
如图16所示，本发明提供了一种应用于所述显示装置的制造方法，所述制造方法包括如下步骤：
步骤S100，在所述第一基板的第一表面11(参见图1、图2、图3或图4)加工所述形变层32(参见图1、图2、图3或图4)；
步骤S200，将所述第一基板的第二表面12(参见图1、图2、图3或图4)与所述第二基板2(参见图1、图2、图3或图4)对盒形成所述显示面板I(参见图1、图2、图3或图4)；
步骤S300，组装所述显示面板I(参见图1、图2、图3或图4)及所述显示装置的其他部件，形成完整的显示装置；
步骤S400，在所述第一形变温度下使所述形变层32(参见图1、图2、图3或图4)带动所述显示面板I(参见图1、图2、图3或图4)弯曲以发生所述第一形变，从而使所述显示装置呈曲面显示，并保持一定时间。
其中，步骤S200对盒形成所述显示面板I(参见图1、图2、图3或图4)，以及步骤S300组装所述显示面板I(参见图1、图2、图3或图4)及所述显示装置的其他部件工艺过程与相应的传统工艺相同。
本实施例所述显示装置与实施例一中所述显示装置结构完全相同，针对所述显示装置结构部分，本实施例不再赘述。
参见图1，由于本发明所述制造方法包括实施例一中所述显示装置的全部内容，本发明所述制造方法也包括所述显示装置的全部效果。本发明通过在所述显示面板I的任一表面设置所述形变层32。所述形变层32达到第一形 变温度时产生第一形变，对所述显示面板I产生内力。由于所述显示面板I自身尺寸不变，如图1A所示，内力会迫使所述显示面板I弯曲，进而使所述显示装置呈曲面显示。可见，本发明所述显示面板I通过自身产生的内力导致弯曲，且本发明所述显示装置在持续的内力作用下可一直保持弯曲。因此，本发明无需使用现有技术中背光组件的护壳来固定形状，从而降低了装配难度。
此外，由于本发明通过在显示面板I任一表面设置形变层32达到曲面显示效果，且无需使用现有技术中背光组件的护壳来固定形状，因此提高了显示面板II的集成度。
此外，由于本发明通过在显示面板I任一表面设置形变层32达到曲面显示效果，且无需使用现有技术中背光组件的护壳来固定形状，使得本发明所述显示装置可应用于无需背光组件的透明显示装置中，拓宽了本发明所述显示装置的应用范围。
此外，由于本发明通过在显示面板I任一表面设置形变层32达到曲面显示效果，且无需使用现有技术中背光组件的护壳来固定形状，因此本发明所述显示装置能够做到轻薄化。
本实施例中，参见图1(或图3)，第一基板1是阵列基板，第二基板2是彩膜基板。其中，第一基板的第一表面11是指远离第二基板2的表面，并且第一基板1的另一表面即为第一基板的第二表面12。第二基板的第一表面21是指远离第一基板1的表面，并且第二基板2的另一表面即为第二基板的第二表面22。
当然本领域普通技术人员可以理解，第一基板1和第二基板2是一个相对概念，参见图2(或图4)，第一基板1还可以是彩膜基板，第二基板2还可以是阵列基板。
具体地，参见图16，本实施实例中，所述第一基板1为阵列基板(参见图1或图3)，在所述第一基板的第一表面11(参见图1或图3)加工所述形变层32(参见图1或图3)之前，在所述第一基板的第二表面12(参见图1或图3)完成阵列基板(参见图1中1或图3中1)图案制作。
