实施例1
如图1所示，一种显示面板100，其定义有识别区域，其中所述显示面板100包括：TFT电路层1、感光层2、显示层3、红外光发射层4、保护层5以及IC模块6。其中所述红外光发射层4能向外发射红外线，所述红外线射入到目标物体后经过反射被感光层2接收，所述感光层2将接收到的光信号转换成电信号，进而形成电流传送给所述IC模块6，所述IC模块6对所述电流进行处理进而识别其中的模型结构。
其中所述显示面板100可以是LCD液晶显示面板，也可以是OLED显示面板。当其为OLED显示面板时，由于OLED是自发光，所以可以通过调整有机发光材料，分别发射R/G/B的光。通过电路控制每个子像素的开关程度，从而混合出不同颜色的光。因此其可以去除显示层3。其中所述TFT电路层1内含驱动电路，其可以传输来自IC模块6的信号，也可以将外界光产生的电信号传输给IC模块6。具体以A-Si结构的TFT电路层1为例，其可以包括玻璃基底层，遮光层，有源层，栅极绝缘层，栅极层，层间绝缘层，源漏极层，平坦层等结构，在此不再赘述。
当其为LCD液晶显示面板时，所述LCD液晶显示面板包括TFT电路层、液晶层、显示层。其中所述TFT电路层还包括背光模组以提供光源。其中显示层3包括彩色滤光片等结构，主要起到滤光作用，将背光模组散发的白光转换成R/G/B单色光。其中所述显示层3设置于所述感光层2上；其中所述液晶层设置于所述感光层2和显示层3之间。因此本实施例对应的是LCD液晶显示面板。
其中所述感光层2设置于所述TFT电路层1上。具体的，所述感光层2包括：电子传输层21、光敏材料层22以及空穴传输层23。其中所述电子传输层21设置于所述TFT电路层1上；所述光敏材料层22设置于所述电子传输层21上；所述空穴传输层23设置于所述光敏材料层22上。感光层2可以用于接收反射回来的红外光，将光信号转换成电信号。当光照射到光敏材料层22，可以产生激子（也就是空穴-电子对），然后电子和空穴分别传输到电子传输层21以及空穴传输层23，产生光生电流。IC模块6对电流进行处理，识别相应的模型结构，判断是否验证通过。
其中所述光敏材料层22的组成材料可以选择有机光敏材料，也可以选择无机光敏材料，本实施例具体选择a-Si。其中所述空穴传输层23通过喷墨打印技术制备形成。其中所述IC模块6连接于所述光敏材料层22。感光层2可以用于接收反射回来的红外光，将光信号转换成电信号。当光照射到光敏材料层22，可以产生激子（也就是空穴-电子对），然后电子和空穴分别传输到电子传输层21以及空穴传输层23，产生光生电流。IC模块6对电流进行处理，识别相应的模型结构，判断是否验证通过。
其中所述红外光发射层4设置于所述显示层3上；其中所述红外光发射层4由红外LED灯组成。所述保护层5设置于所述红外光发射层4上；所述IC模块6连接于所述感光层2上，所述IC模块6包括人脸识别IC模块和指纹识别IC模块。
其中所述保护层5的组成材料包括SiNx、SiOx、SiONx、SiCNx、AL2O3中的一种或多种。由此可以很好的阻绝水氧入侵，可以延长显示面板100的使用寿命。
其中所述识别区域可以根据个人喜好设置成指纹识别区域102，其中所述红外光发射层4向外发射红外线，所述红外线射入到手指指纹谷和脊之后经过反射被设置在所述识别区域的感光层2接收，由于光遇到谷和脊的反射率差别很大，从而产生不同的光生电路，所述感光层2将接收到的光信号转换成电信号，进而形成电流传送给所述IC模块，所述IC模块对所述电流进行处理，识别出指纹的形貌，进而识别其中的指纹模型结构。其中所述红外光发射层4和光敏材料层22是正面涂覆的，所以可以实现指纹在显示面板100的任何区域都可以进行指纹识别，不必局限于某一个区域，增加了指纹识别的面积，使得指纹识别更加方便，增加客户体验好感。
其中所述识别区域还可以根据个人喜好设置成人脸识别区域101，其中所述红外光发射层4向外发射红外线，所述红外线射入到眼镜，鼻子和耳朵等面部特征之后经过反射被设置在所述识别区域的感光层2接收，所述感光层2将接收到的光信号转换成电信号，进而形成电流传送给所述IC模块，所述IC模块对所述电流进行处理，分析面部特征，进而识别其中的人脸模型结构。其中所述红外光发射层4和光敏材料层22是正面涂覆的，所以可以实现在显示面板100的任何区域都可以进行人脸识别，不必局限于某一个角度，增加了人脸识别的面积，使得人脸识别更加方便，增加客户体验好感。其中所述IC模块可以设置在显示面板100下方，由此可以避免在顶部开孔放置摄像头和红外发射器，可以极大地提高屏占比以及降低制造工艺难度。
实施例2
