所述第一发光二极管LED_1、所述红外发光二极管LED_IR及所述第二发光二极管LED_2呈现菱形分布。于一实施例中，由于绿色发光二极管的特性(例如发光效率及寿命)的变化小于红色发光二极管及蓝色发光二极管的特性变化，因此将所述红外发光二极管LED_IR集成至绿色的第一发光二极管LED_1不仅能有效利用空间，还能够降低所述红外发光二极管LED_IR对分辨率的影响。也就是说，所述第一发光二极管LED_1可以为绿色发光二极管，所述第二发光二极管LED_2可以为红色发光二极管或蓝色发光二极管。
如图4所示的菱形50的区域中，一对角线的两端为红外发光二极管LED_IR集成至绿色发光二极管，另一对角线的两端分别为红色发光二极管及蓝色发光二极管。因此，菱形50的区域包括绿色发光二极管、红色发光二极管、蓝色发光二极管及红外发光二极管LED_IR。
要说明的是，所述红外发光二极管LED_IR亦可集成至红色发光二极管或蓝色发光二极管。
请参阅图5，图5显示根据本揭示实施例之第一发光二极管LED_1、红外发光二极管LED_IR及感应单元102的部分结构示意图。
柔性基板500可以但不限于为一聚酰亚胺(Polyimide，PI)柔性基板。
半导体层501的材料例如为低温多晶硅(Low Temperature Poly-Silicon，LTPS)。
所述柔性基板500与所述半导体层501之间可设置缓冲层。
绝缘层502及503的材料例如为氮化硅(SiNx)或二氧化硅(SiO2)。
半透明有机绝缘层504及505需对红外光有较好的透过率。
金属导电层510、511及512作为图2中用于控制第一发光二极管LED_1的薄膜晶体管(第一薄膜晶体管T11或第二薄膜晶体管T12)的电极(栅极、源极和汲极)。
金属导电层512、521及522作为图2中用于控制红外发光二极管LED_IR的薄膜晶体管(第三薄膜晶体管T21或第四薄膜晶体管T22)的电极(栅极、源极和汲极)。
金属导电层530、531及532作为图2中感应单元102的薄膜晶体管(第五薄膜晶体管T31或第六薄膜晶体管T32)的电极(栅极、源极和汲极)。
阳极540、有机发光层541及阴极560形成图2之第一发光二极管。所述阳极540具有反射层，例如ITO-Ag-ITO。所述有机发光层541能产生红光、绿光或蓝光。所述阴极560为透明电极。
阳极550、有机发光层551及所述阴极560形成图2之红外发光二极管LED_IR。所述阳极550具有反射层，例如ITO-Ag-ITO。所述有机发光层551能产生红外光。
半导体层533及阻光层534形成图2之感应单元102的光感应结构。所述半导体层533对红外光敏感，例如掺杂锗的非晶硅(a-Si)。当红外光照射所述半导体层533时会影响所述感应单元102的薄膜晶体管(第五薄膜晶体管T31或第六薄膜晶体管T32)的电流。所述阻光层534可阻挡可见光并让红外光通过，例如为含有非晶硅锗(a-SiGe)材料的膜层结构。
光线L1为图2之第一像素100的第一发光二极管LED_1在显示影像时发出的可见光。光线L2为图2之红外发光二极管LED_IR发射的红外光。光线L3为光线L2在遇到待探测物后反射的红外光或者环境中的红外光。
本揭示之发光二极管显示装置中，将所述红外发光二极管及所述感应单元制作于显示区(像素阵列)中，故无需设置外挂式识别模块，进而能达成全屏识别(例如指纹识别)并降低发光二极管显示装置的体积及重量。
综上所述，虽然本揭示已以优选实施例揭露如上，但上述优选实施例并非用以限制本揭示，本领域的普通技术人员，在不脱离本揭示的精神和范围内，均可作各种更动与润饰，因此本揭示的保护范围以权利要求界定的范围为准。
