 本发明的实施方式
下面结合附图和实施例，对本申请作进一步的详细描述。特别指出的是，以下实施例仅用于说明本申请，但不对本申请的范围进行限定。同样的，以下实施例仅为本申请的部分实施例而非全部实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
本申请针对现有技术中显示面板的边框宽度以及显示区界面美化的技术问题，本实施例能够解决该缺陷。
如图1所示，本申请实施例提供一种显示装置100，包括液晶显示面板101，位于液晶显示面板101背部的背光模组102、以及位于液晶显示面板101与背光模组102之间的摄像组件103；液晶显示面板101上设置有透光区1011，摄像组件103与透光区1011对位设置，摄像组件103包括感光元件1031和光阀1032，光阀1032靠近背光模组102设置。
具体地，本实施例中液晶显示面板101设置有透光区1011；透光区1011包括阵列分布的像素单元，该像素单元的尺寸比透光区1011以外像素单元的尺寸小，且该像素单元的间隙比透光区1011以外像素单元的间隙大；便于光线的传递。透光区1011的表面积大于或等于感光元件1031的表面积，即摄像组件103在透光区1011的投影位于透光区1011中，便于感光元件1031成像的范围更大，透光区1011的形状优选为圆形或圆角平行四边形。透光区1011中像素单元包括液晶、像素电极以及色阻，该像素单元配合摄像组件103摄像与非摄像，该像素单元连接有独立驱动电路，该驱动电路用于驱动该像素单元中液晶的偏转，其中，该驱动电路为薄膜晶体管矩阵。摄像组件103开启摄像模式时，透光区1011中像素单元为透光状态，感光元件1031通过透光区1011采集外界图像信息，摄像组件103关闭摄像模式时，透光区1011中像素单元由背光模组出射光点亮以恢复显示功能。透光区1011中像素单元连接有驱动电路，驱动电路为薄膜晶体管矩阵，驱动电路用于控制该像素单元中液晶的偏转角度，决定该像素单元中液晶是否展开和关闭状态，外界光线是否可以穿过透光区1011在显示面板101的两侧传递。
在显示面板101背部对应于透光区1011下方设置有摄像组件103，摄像组件103包括感光元件1031和光阀1032，光阀1032包括玻璃基片以及位于玻璃基片内的电致变色材料，该电致变色材料为氧化铟锡和三氧化钨的一种或两者的组合材料，以控制光阀1032的开/闭状态。光阀1032连接有控制端，控制端为光阀1032提供电信号或断开电信号；摄像组件103开启摄像模式时，光阀1032处于遮光状态，背光模组102的光线无法穿过光阀1032，摄像组件103关闭摄像模式时，光阀1032处于透光状态，背光模组102的光线穿过光阀1032，为透光区1011提供背光源。
电致变色材料能够在透光与不透光状态之间可逆地转换。电致变色材料的光学属性在一定的条件下可以发生可逆转化的，外加电场的作用下，反射率、透过率、吸收率等快速响应。目前已经开始运用于信息和能源、建筑等方面，例如氧化铟锡导电玻璃和三氧化钨的变色玻璃，电致变色材料的电源回路接通，该变色玻璃立即改变反射率和吸收率以及颜色，光无法穿过该区域。电致变色材料具有以下优越性：快速的变色响应；颜色变化的可逆；颜色变化的高灵敏度；较高的循环使用寿命；具有一定的存贮记忆功能；稳定的化学性质。运用到显示面板屏幕上进行正常显示时，具有高透过率，背光源的光穿过电致变色玻璃和感光元件后，能够正常经过显示面板，进行显示。在切换到拍照模式后，外部待拍摄物体的光经过显示面板屏幕上对应区域在感光元件正常成像，从而达到拍照/摄像的功能。
本实施例中光阀1032嵌设于背光模组102中，感光元件1031和光阀1032共用一个控制端，控制端用于实现摄像组件103摄像与非摄像之间切换，光阀1032的电路连接在控制端上，控制端的开启和关闭决定光阀1032是否允许背光模组出射的光线穿过；感光元件1031位于光阀1031和透光区1011之间。
感光元件1031具有成像工作模式和投影工作模式，当感光元件1031处于成像工作模式时，感光元件1031通过透光区1011感光成像，且光阀1031阻止背光模组102出射光穿过光阀1032；当感光元件1031处于投影工作模式时，感光元件1031在透光区1011上形成投影图像，且光阀1031允许背光模组102出射光穿过光阀1032。本实施例中摄像组件103还包括图像传感器，数字信号处理器，逻辑供电电源等组件，感光元件1031生成光学图像，投射到图像传感器表面上，然后转成电信号，经过A\D转换后变成图像数字信号，再送到数字信号处理器芯片DSP处理，通过显示屏显示出图像。本实施例中感光元件1031设置在显示面板101的外部，即设置在显示面板101的下方，有利于显示面板101实现全面屏，彻底解决了显示面板边框的问题。
如图2所示，本申请实施例提供一种显示装置100正常显示时光线传播示意图，显示装置100包括液晶显示面板101、背光模组102、以及摄像组件103，其中，液晶显示面板101包括上基板1013，液晶层1014，透光区1011中液晶层1014设置有透光部1012，透光部1012中设置有多个液晶，透光区1011中像素单元包括液晶、像素电极以及色阻；其中，透光区1011中像素单元配合摄像组件103摄像与非摄像，透光区1011中像素单元连接有独立驱动电路，该驱动电路为薄膜晶体管矩阵，该驱动电路仅仅控制透光部1012中液晶的偏转，该驱动电路与透光部1012以外的液晶的驱动电路是相互独立；液晶层1014下方设置有下基板1015，下基板1015和透光部1012正下方设置有感光元件1031，下基板105下方设置有摄像组件103，摄像组件103包括感光元件1031和光阀1032，感光元件1031分为两层，包括感光板和成像元件10311，感光板采集从实体反射回来的光线，然后在成像元件10311上投影，获取摄像的原始数据，光阀1032嵌设于背光模组102中光学膜材1021，光学膜材1021下方设置有光源1022。
显示装置100处非摄像模式，正常显示时，光源1022发射出光线，经过光学膜材1021，由线光源变成面光源，面光源传递到显示面板101中，显示面板101的显示屏进行正常显示，在透光部1012中面光源正常穿过，此时透光部1012的液晶与透光部1012以外的液晶排列方向一致。
如图3所示，本申请实施例提供一种显示装置100摄像时光线传播示意图，显示装置100处摄像模式，开启控制端，透光区1011中像素单元配合摄像组件103进行摄像，光阀1032接通电信号，立即改变反射率和吸收率以及颜色，光无法穿过光阀1032，光阀1032下方的光线在光阀1032处被吸收或者反射回去，同时透光区1012中液晶连接有独立驱动电路，该驱动电路控制透光部1012中液晶的偏转到预设角度，允许实体104表面反射光线可以传递到感光元件1031中感光板上，然后在成像元件10311上形成光学图像1041，摄像过程中透光区1012中液晶偏转方向跟透光区1012以外液晶偏转方向不同，光阀1032以外光线正常穿过光学膜材1021，显示面板101的显示屏进行正常显示。
