具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图对本发明提供的一种显示装置、显示系统和显示方法进行详细描述。
当前，为避免蓝光对用户眼睛造成损伤，一般是在显示面板表面贴附蓝光过滤膜以过滤部分蓝光，从而达到护眼的目的。然而，贴附蓝光过滤膜后，显示面板的整体亮度降低、画面色域降低，影响显示面板的显示质量；此时，若用户希望体验高亮度、高色域的正常显示画面，则必须撕去蓝光过滤膜。因此，当用户希望显示装置在“护眼显示模式”和“正常显示模式”之间进行切换时，需要不断进行贴膜和撕膜的操作，使用过程极其不便。
本公开的技术方案可有效改善上述问题，使得用户能够方便的控制显示装置在“护眼显示模式”和“正常显示模式”之间进行切换。
图1为本公开实施例提供的一种显示装置的截面示意图，如图1所示，该显示装置包括：发光器件1和光调整层2，光调整层2位于发光器件1的出光侧，发光器件1用于产生并发出处于可见光波长范围(380nm～780nm)的光线；光调整层2配置为在施加有预定外部刺激时能够阻挡预定波长范围内的蓝光(即，部分波长范围的蓝光)通过，且在预定外部刺激撤除时可见光波长范围内的全部光线可通过。
在实施例中，光调整层2包括光子晶体。在实施例中，光调整层2包括可响应光子晶体。
在本公开中，光子晶体(Photonic Crystal)是指具有光子带隙(Photonic Band-Gap，简称为PBG)特性的人造的且具有周期性的电介质结构，有时也称为PBG光子晶体结构。所谓的光子带隙是指某一频率范围的波不能在此周期性结构中传播，即这种结构本身存在“禁带”。
可响应光子晶体(Responsive Photonic Crystal)是指光子带隙的位置和宽度能够随着外部环境变化而改变的光子晶体。其中，有很多种外界刺激可以驱动光调整层2光学特性的变化，包括：温度、化学试剂、机械力、光、电场、磁场等。
在本公开的技术方案中，光调整层2配置为在施加有预定外部刺激时能够阻挡处于预定波长范围的蓝光通过，且在外部刺激撤除时处于预定波长范围的蓝光可通过。需要说明的是，本公开中的预定外部刺激可以是温度刺激、化学试剂刺激、机械力刺激、光刺激、电场 刺激、磁场刺激中的一种或多种的结合。
光调整层2位于发光器件1的出光侧，当向该光调整层2施加外部刺激时，发光器件1所发出的波长处于预定波长范围内的蓝光无法通过(透射)光调整层2，与此同时波长处于预定波长范围外的光能够通过(透射)光调整层2；当将该光调整层2所受外部刺激撤除时，发光器件1所发出的波长处于预定波长范围内的蓝光能够通过光调整层。
基于上述原理，当用户希望显示装置工作于“护眼显示模式”时，仅需向显示装置中的光调整层2施加预定外部刺激，以使得波长处于预定波长范围内的蓝光无法透射过光调整层2，从而无法进入用户眼睛，进而达到护眼的目的。当用户希望显示装置工作于“正常显示模式”时，可以撤除光调整层2所受的预定外部刺激，以使得波长处于预定波长范围内的蓝光能够通过光调整层2，从而进入用户眼睛，进而达到高亮度、高色域的正常显示的目的。
在本公开中，光调整层2可仅设置在用于发出蓝光的蓝色亚像素区域处(此种情况未给出相应附图)，而其他颜色亚像素区域不设置光调整层2。
然而，考虑到仅在蓝色亚像素区域设置光调整层2的制备工艺难度较大，本公开中将光调整层2整层铺设(参见图1所示)，即光调整层2覆盖显示装置中的全部亚像素。此时，为避免光调整层2阻挡其他颜色(除蓝色外)亚像素区域所发出的光，则应使得光调整层2无论其是否受到预定外部刺激，该光调整层2均不会阻挡其他颜色亚像素区域所发出的光；作为一种可选方案，针对波长处于可见光波长范围内光线，当光调整层受到预定外部刺激时，光调整层能够阻挡波长处于预定波长范围内的蓝光，而波长处于预定波长范围外的可见光能够通过光调整层2，当预定外部刺激撤除时，波长处于可见光波长范围内的任意光线(包括波长处于预定波长范围内的蓝光)均能够通过光调整层2。
在一些实施例中，预定波长范围包括：420nm～450nm。蓝光的波长范围为400nm～480nm，其中对人眼伤害较大的蓝光波长范围为 420nm～450nm，因此在护眼显示模式时，仅需过滤到波长处于420nm～450nm的蓝光，而处于其他波长范围的蓝光未被过滤掉，以保证显示装置在护眼显示模式时也能实现全彩显示。当然，在本公开中还可以根据实际需要来对预定波长范围进行设定和调整。
在本公开的技术方案中，通过向光调整层2施加预定外部刺激或撤除预定外部刺激，即可实现显示装置在“护眼显示模式”和“正常显示模式”之间进行切换，切换过程十分简便。
在一些实施例中，光调整层2包括：电场响应光子晶体。其中，电场响应光子晶体是指在外部环境中的电场发生改变时光子带隙的位置和宽度可发生改变的光子晶体。此时，预定外部刺激是指可以改变光子晶体所处的电场的刺激。
图2为本公开中光调整层2受到外部刺激(图2的左侧)以及撤除外部刺激(图2的右侧)时的示意图，如图2所示，作为一种可选实施方案，光调整层包括：层叠设置的第一电极201、电解液层203、电活性层204和第二电极202；电解液层203和电活性层204位于第一电极201和第二电极202之间，第一电极201和第二电极202在被施加有不同电压时可形成电场。
为保证在在正常显示模式时光调整层的整体透光率，第一电极201和第二电极202可以采用无色透明导电材料(例如，氧化铟锡)制成。
电解液层203包括电解液203b以及封装电解液的树脂材料203a(例如，为环氧树脂)，电解液203b可以是有机酸盐或无机酸盐，电解液203b在电场作用下不与其他层反应；此外，电解液203b中的离子导电率较高，以保证易于实现阴、阳离子的迁移和传输。
电活性层204是电场响应光子晶体的核心部件，多为蛋白石(Opal)型和反蛋白石(Inverse Opal)型两种。蛋白石的微观结构为面心立方，是一种三位光子晶体，可以发生选择性布拉格反射，从不同角度观察会呈现不同颜色；反蛋白石就是在蛋白石晶体空隙中填充某种电活性材料，然后通过焙烧、溶解或化学腐蚀等方法除去蛋白石晶体的原材料后所形成的多孔结构205，即空气小球以面心立方的 形式分布于介质中。
当向第一电极201和第二电极202施不同电压以形成电场时，电解液203b涌入电活性层204使其体积膨胀，引起光子晶体晶格参数的变化，从而实现电场响应；当改变第一电极201和第二电极202上的电压(第一电极201和第二电极202上加载的电压相同，或者第一电极201和第二电极202上未加载电压)以撤除电场时，涌入至电活性层204中的电解液析出，电活性层204体积恢复至原始状态，光子晶体晶格参数恢复至初始水平。
基于上述原理，当用户希望显示装置工作于“护眼显示模式”时，可向第一电极201和第二电极202分别施加预定电压，以在第一电极201和第二电极202之间形成预定电场(即施加预定外部刺激)，从而使得光子晶体晶格参数变化，且此时的光子晶体能够阻挡波长处于预定波长范围的蓝光通过；当用户希望显示装置工作于“正常显示模式”时，可以通过停止向第一电极201和第二电极202施加电压以撤除预定电场，光子晶体晶格参数恢复至初始水平，且此时的光子晶体能够使得波长处于预定波长范围内的光线通过。
在一些实施例中，显示装置为液晶显示装置，液晶显示装置包括：背光模组和液晶显示面板3，液晶显示面板3位于背光模组的出光侧，此时发光器件1为背光模组。
其中，背光模组一般包括光源、导光板、光学膜片，还可以包括用于将光源、导光板、光学膜片和液晶显示面板3进行固定的胶框和边框。本公开的技术方案对背光模组的具体结构不作限定。
液晶显示面板3包括：进行对盒的第一显示基板和第二显示基板，第一显示基板包括：第一衬底301，第二显示基板包括：第二衬底302，第二衬底302位于第一衬底301背向背光模组的一侧。在实施例中，第一显示基板和第二显示基板中之一为阵列基板，另一为对盒基板。第一衬底301和第二衬底302之间可以包括液晶层、彩色滤光片、驱动IC等。
光调整层2的设置位置可以有多种。作为一种可选方案，参见图1所示，光调整层2位于背光模组和第一衬底301之间。作为一种 可选实现方式，光调整层2通过双面胶固定于第一衬底301朝向背光模组的一侧表面上；作为另一种可选实现方式，光调整层2设置在第一衬底301中。对于其他实现方式，此处不再一一举例说明。
图3为本公开实施例提供的另一种显示装置的截面示意图，如图3所示，与图1中所示不同的是，在图3中，光调整层2位于第二衬底302背向背光模组的一侧。作为一种可选实现方式，光调整层2通过双面胶固定于第二衬底302背向背光模组的一侧表面上。对于其他实现方式，此处不再一一举例说明。
图1中所示光调整层2位于背光模组和第一衬底301之间，以及图3中光调整层2位于第二衬底302背向背光模组的一侧的情况，仅起到示例性作用，其不会对本公开的技术方案产生限制。在本公开中，光调整层2还可以设置于其他位置，例如，光调整层2设置于第一衬底301和第二衬底302基板之间(未给出相应附图)。
需要说明的是，当光调整层2设置于第一衬底301和第二衬底302之间时，应保证液晶显示面板3中用于控制液晶偏转的液晶电场不会对光调整层2的中光子晶体的晶格参数产生作用，且施加至光调整层2的预定外部刺激不会对液晶偏转产生作用。
图4为本公开实施例提供的又一种显示装置的截面示意图，如图4所示，与前述实施例不同的是，显示装置为有机发光二极管(Organic Light-Emitting Diode,简称OLED)显示装置，有机发光二极管显示装置包括：有机发光二极管显示面板，有机发光二极管显示面板包括有机发光二极管阵列(包括多个OLED 4)，发光器件1为有机发光二极管阵列。
需要说明的是，本实施例中的有机发光二极管显示面板既可以是有机发光二极管4直接发出彩色光，也可以是有机发光二极管4发出白光后经过彩色滤光膜作用后形成彩色光，上述两种情况均应属于本发明的保护范围。
图5为本公开实施例提供的一种显示系统的结构框图，如图5所示，该显示系统包括：显示装置，该显示装置采用前述实施例所提供的显示装置。对于该显示装置的描述，可参见前述内容，此处不再 赘述。
在一些实施例中，显示系统还包括：控制器和电压发生器。电压发生器连接在控制器和光调整层之间，用于响应于控制器的控制向光调整层施加电压。在本文中，向光调整层施加预定外部刺激可以包括向光调整层施加电压，对光调整层的预定外部刺激去除可以包括停止向光调整层施加电压。
在实施例中，控制器包括：实体按键或虚拟按键。用户可通过操作控制器来对电压发生器进行控制，从而实现对显示装置的显示模式进行控制。当控制器包括实体按键时，实体按键可以集成在显示装置上或集成在可对显示装置进行控制的遥控器上。当控制器包括虚拟按键时，虚拟按键可以为显示于显示终端(例如手机、平板、显示屏)的屏幕上的虚拟按键，在用户操作虚拟按键时显示该按键的显示终端能够向电压发生器发出相应的控制指令。例如，实体按键(或虚拟按键)可以包括与显示装置的“正常显示模式”对应的第一按键以及与显示装置的“护眼显示模式”对应的第二按键。
电压发生器既可以集成在显示装置上，也可以独立于显示装置而存在。
作为一种具体实施方案，参见图2所示，当光调整层2包括可响应光子晶体结构，且光调整层2包括：层叠设置的第一电极201、电解液层203、电活性层204和第二电极202时(图2所示光调整层)，电压发生器与第一电极201和第二电极202电连接。在期望显示装置处于护眼显示模式时，电压发生器用于分别向第一电极201和第二电极202提供不同电压以形成预定电场(向光调整层施加预定外部刺激)，以及在在期望显示装置处于正常显示模式时停止向第一电极201和第二电极202提供电压以撤除预定电场(撤除预定外部刺激)。
在实施例中，在在期望显示装置处于正常显示模式时也可以向第一电极201和第二电极202提供相同的电压。
在实际应用中，可设计显示装置开机时默认工作于正常显示模式，用户可根据需要(例如，长时间使用或儿童使用)来将显示装置切换至护眼显示模式。
图6为本公开实施例提供的一种显示方法的流程图，如图6所示，该显示方法基于前述实施例提供的显示装置，该显示方法可以包括：
步骤S1、在期望显示装置处于护眼显示模式时，向光调整层施加预定外部刺激，光调整层阻挡波长处于预定波长范围内的蓝光通过。
步骤S2、在期望显示装置处于正常显示模式时，停止向光调整层施加预定外部刺激，光调整层可使得波长处于预定波长范围内的蓝光通过。
可以理解的是，通过触摸或按压与“护眼显示模式”对应的第二按键，可以控制电压发生器向光调整层2的第一电极201和第二电极202施加不同的电压(即，向光调整层施加预定外部刺激)，使得光调整层阻挡波长处于预定波长范围内的蓝光通过。类似地，通过触摸或按压与“正常显示模式”对应的第一按键，可以控制电压发生器停止向光调整层2施加电压(即，向光调整层撤除预定外部刺激)，使得光调整层允许可见光范围内的所有光通过。
通过交替执行上述步骤S1和步骤S2，即可实现显示装置在“护眼显示模式”和“正常显示模式”之间进行切换。
在本公开的技术方案中，通过向光调整层施加预定外部刺激或撤除预定外部刺激，即可实现显示装置在“护眼显示模式”和“正常显示模式”之间进行切换，切换过程十分简便。

    所述发光器件为所述有机发光二极管阵列。
  7. 根据权利要求1-6中任一所述的显示装置，其中，所述部分波长范围为：420nm～450nm。
  8. 一种显示系统，包括：如上述权利要求1-7中任一所述的显示装置。
  9. 根据权利要求8所述的显示系统，还包括：控制器和电压发生器；
    所述控制器用于响应用户的操作来控制所述电压发生器是否产生电压；
    所述电压发生器用于通过产生电压来向所述光调整层施加外部刺激，并且通过不产生电压来停止向所述光调整层施加外部刺激。
  10. 根据权利要求9所述的显示系统，其中，所述光调整层包括：层叠设置的第一电极、电解液层、电活性层和第二电极，所述电压发 生器与所述第一电极和所述第二电极电连接，所述电压发生器通过分别向所述第一电极和所述第二电极提供不同电压以在所述第一电极和所述第二电极之间形成电场来向所述光调整层施加外部刺激，以及通过停止向所述第一电极和所述第二电极提供电压来停止向所述光调整层施加外部刺激。
  11. 根据权利要求9所述的显示系统，其中，所述控制器包括：实体按键或虚拟按键。
  12. 一种显示方法，所述显示方法基于上述权利要求1-7中任一所述的显示装置，所述显示方法包括：
    在期望显示装置处于护眼显示模式时，向所述光调整层施加外部刺激，所述光调整层阻挡波长处于蓝光的部分波长范围内的光通过；
    在期望显示装置处于正常显示模式时，停止向所述光调整层施加外部刺激，所述光调整层允许波长处于蓝光的部分波长范围内的光通过。
