 本发明的实施方式
本发明针对现有的触控显示装置，由于现有的触控显示装置中，指纹识别模组是单独设置的一个配件，会增加制程工序和成本，也会增加显示装置的厚度，不利于显示装置的轻薄化发展，本实施例能够解决该缺陷。
本发明提供一种触控显示装置，所述显示装置定义有显示区域和围绕该显示区域设置的非显示区域，所述显示区域用以实现指纹识别功能、触控功能以及显示功能，所述非显示区域用以容纳金属走线以及其他器件。
所述显示装置包括保护层、显示模组、触控层、指纹传感器层、背光源、以及遮光层。
其中，所述显示模组、触控层、以及指纹传感器层均设置于所述保护层的下方。
所述背光源设置于保护层下方对应的非显示区域内，所述背光源为2个或多个偶数个点状光源，均匀分布在所述指纹传感器层的四周，所述光源为LED灯，LED灯发出的光可为蓝光、红光或近红外光。
所述遮光层设置于所述显示区域的侧面，具体地，所述遮光层设置于所述指纹传感器层和所述触控层的侧边与所述背光源之间，用以避免所述背光源的出射光线从所述触控层和所述指纹传感器层的侧面进入保护层，导致光线经不同的介质折射后使得指纹图像采集时出现重影现象。
所述触控显示装置还包括设置于非显示区域的柔性电路板和驱动芯片，所述指纹传感器层和所述触控层上的信号走线均通过所述电路板与所述驱动芯片连接，所述指纹传感器层与所述触控层，触控功能和指纹识别功能集成在同一芯片内。

所述触控显示装置10包括保护层11、显示模组12、触控层13、指纹传感器层14、背光源15、遮光层16、第一粘合层19。
其中，所述保护层11为透光基板，如玻璃基板，所述保护层11具有相对的第一表面和第二表面，所述第二表面用于人体手指的指纹接触。
所述触控层13设置于所述保护层11和所述显示模组12之间，所述指纹传感器层14设置于所述触控层13与所述显示模组12之间，所述触控层13与所述指纹传感器层14均位于所述显示区域AA内。
本实施例的触控层13为外挂式结构，即OGS、GG、GF、GG、等结构，本实施例的触控层13以OGS结构进行说明，将所述触控层13的图案直接制备在所述保护层11的第二表面上，再在所述触控层13背离所述保护层11一侧的表面制备所述指纹传感器层14，所述指纹传感器层14与所述触控层13共用同一个基板，能够使显示装置的整体厚度降低0.2~0.4毫米。
所述指纹传感器层14与所述显示模组12之间设置有第一粘合层19，由于所述保护层11、所述触控层13、以及所述指纹传感器层14是一体的，因此需要设置所述第一粘合层19，用以贴合连接所述指纹传感器层14与所述显示模组12，所述第一粘合层19可为热敏光学胶层、光敏光学胶层或光学双面胶带。
所述光学指纹传感器层14上设置有感光像素区，所述感光像素区位于显示区域AA内，所述感光像素区包括多个呈行列矩阵排列的像素，所述像素的行列之间设置有相应的数据线和扫描线，所述数据线和扫描线交叉排列，具体地，多条所述数据线沿第一轴向排列，多条所述数据线沿第二轴向排列，第一轴向与第二轴向垂直，所述扫描线与所述数据线限定出多个网格，每一网格对弈一个像素，所述像素可为方形，所述网格的每条边小于或等于100微米。
所述触控显示装置10还包括设置于非显示区域NA内的柔性电路板17和驱动芯片18，所述柔性电路板17设置于所述触控层13的侧面，所述驱动芯片18与所述柔性电路板连接，所述触控层13和所述光学指纹传感器的信号走线（如数据线、扫描线）均通过所述柔性电路板17连接到所述驱动芯片18上，即触控功能和指纹识别功能集成在同一芯片内，可以分时操作。

所述背光源15的出射光线与所述保护层11的第一表面（靠近所述显示模组12一侧的表面）所成夹角为锐角。
所述遮光层16设置于所述背光源15与所述指纹传感器层的侧边之间，所述遮光层16位于非显示区域NA内，且靠近所述显示区域AA，所述遮光层16用以避免入射光线从所述触控层13和所述指纹传感器层14的侧面进入所述保护层11，由于光线经过介质折射再进入保护层11第二表面反射，在指纹图像采集时易发生重影现象，进而造成指纹图像不清晰。
进一步地，所述遮光层16背离所述显示模组12一侧的表面应不低于所述触控层13背离所述显示模组12一侧的表面，从而提高遮光效果；所述触控层13所选用材料的折射率与所述保护层11的折射率相同，折射率误差在5%以内。
