Description

一种集成指纹识别功能及太阳能电池模块的显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种集成指纹识别功能及太阳能电池模块的显示装置。
 背景技术
近年来，大众对全面屏(full screen display)显示装置有相当高的兴趣。然而，对于具有指纹识别功能的显示装置而言，由于需安排特定区域来配置指纹识别模组，并不易实现全面屏的效果。
再者，现有的显示装置普遍有耗电快速的问题。当显示装置充电时，仍需通过充电装置或者移动电源来进行充电，此对使用者而言相当不便。
因此，有必要提供一种集成指纹识别功能及太阳能电池模块的显示装置，以解决上述问题。

 附图说明
为让本发明的特征以及技术内容能更明显易懂，请参阅以下有关本发明的详细说明与附图，然而附图仅提供参考用，并非用来对本发明加以限制。
图1为根据本发明实施例的显示装置的示意图；
图2A为根据本发明实施例一的子像素单元于太阳能充电状态下的剖面示意图；
图2B为根据本发明实施例一的子像素单元于指纹识别状态下的剖面示意图；

 本发明的实施方式
为了使本发明的目的、技术手段及其效果更加清楚明确，以下将结合附图对本发明作进一步地阐述。应当理解，此处所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例，并不用于限定本发明。
请参考图1，其示出根据本发明实施例的显示装置的示意图。如图1所示，显示装置1具有显示屏10，显示屏10包括多个子像素单元100。在一些实施例中，显示屏10可以为有机发光二极管显示屏或液晶显示屏。
请参考图2A，其示出根据本发明实施例一的子像素单元于太阳能充电状态下的剖面示意图。显示装置1包括显示屏10、蓄电池单元20及控制芯片30。再者，子像素单元100包括：晶体管105、太阳能电池模块103及发光器件104。太阳能电池模块103包括依序重叠的第一电极1030、光感器件1031及第二电极1032。如图2A所示，第一电极1030与晶体管105的漏极1050电连接。光感器件1031用于将光信号转化为电信号。发光器件104与太阳能电池模块103间隔设置。蓄电池单元20电连接第一电极1030和第二电极1032。
继续参考图2A，显示装置1还包括阵列基板101。在本实施例中，晶体管105和太阳能电池模块103依序形成于阵列基板101上，且晶体管105的漏极1050通过过孔106与第一电极1030电连接。在一些实施例中，光感器件1031为独立的光感二极管，且所述光感二极管的二端分别电连接第一电极1030和第二电极1032。
在图2A中，当手指未触摸显示屏10时，太阳光线L1入射到光感器件1031的表面，使得光感器件1031产生电信号或电流。然后，蓄电池单元20储存光感器件1031产生的电信号，也就是，对蓄电池单元20进行充电。此时，晶体管105会被关闭，显示装置1不执行指纹识别功能。
请参考图2B，其示出根据本发明实施例一的子像素单元于指纹识别状态下的剖面示意图。当发光器件104发出的光线L2经由触摸显示屏10的手指反射至光感器件1031时，晶体管105会被导通，光感器件1031会产生相应的指纹信号，然后控制芯片30储存且识别所述指纹信号。同时，当发光器件104发出的光线L2经由触摸显示屏10的手指反射至光感器件1031时，亦会产生电流，然后对蓄电池单元20进行充电。
请参考图2C，其示出图1的子像素单元的局部透视图。在本实施例中，第二电极1032可以具有栅形结构，以确保太阳光线L1和发光器件104发出的光线L2可以入射到光感器件1031的表面，同时减小了第二电极1032与光感器件1031之间的接触电阻。具体地，第二电极1032的材料为透明导电材料，光感器件1031的材料为非晶硅薄膜、铜铟硒薄膜、铜铟镓硒薄膜、以及碲化镉薄膜的其中一种。
请参考图3，其示出图1的子像素单元的等效电路图。同时参考图3和图2C，子像素单元100包括彼此交叉的栅极线GL和指纹信号线SL。晶体管105的栅极1051电连接栅极线GL，控制芯片30通过指纹信号线SL电连接晶体管105的源极1052，第一电极1030与晶体管105的漏极1050电连接。在本实施例中，控制芯片30还可以被配置为通过栅极线GL电连接晶体管105的栅极1051以提供栅极扫描信号。
图4A为根据本发明实施例二的子像素单元于太阳能充电状态下的剖面示意图。图4A与图2A的差别在于，发光器件104与太阳能电池模块103系设置于同一层(如图4A所示)，且它们通过光学胶107直接与盖板108黏合在一起，如此可节省制造成本，且使得显示装置1更为轻薄。图4A的运作方式与图2A相同，于此不再赘述。
图4B为根据本发明实施例二的子像素单元于指纹识别状态下的剖面示意图。图4B与图2B的差别在于，发光器件104与太阳能电池模块103系设置于同一层(如图4B所示)，且它们通过光学胶107直接与盖板108黏合在一起，如此可节省制造成本，且使得显示装置1更为轻薄。图4B的运作方式与图2B相同，于此不再赘述。
综上所述，本发明提供的显示装置主要通过集成指纹识别功能及太阳能电池模块，而不需安排特定区域来配置指纹识别模组，且不需通过充电装置进行充电，从而提高使用的便利性。
应当理解的是，本发明的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本发明所附权利要求的保护范围。
 工业实用性
本发明提供的显示装置不需安排特定区域来配置指纹识别模组，且不需通过充电装置进行充电，从而提高使用的便利性。
