在本实施例中，每个像素单元2中，红色滤光单元R、绿色滤光单元G、蓝色滤光单元B和第二类滤光单元4沿行向并排设置。
本公开实施例提供的彩膜基板1应用于显示装置时，第一类滤光单元3允许可见光通过且阻挡不可见光通过，使显示装置能够显示出供人们观看的图像信息；第二类滤光单元4允许不可见光通过且阻挡可见光通过，使显示装置能够显示出供专用设备读取且人眼不可见的机读信息；由于图像信息和机读信息不重叠，人们在观看图像信息时看不见机读信息，从而可以改善相关技术中机读信息对人眼造成的视觉混淆，从而提高显示装置的显示效果。
如图3所示，本公开的又一些实施例提供了一种彩膜基板1，该彩膜基板1包括前述实施例中的呈阵列排布的多个像素单元2，每个像素单元2包括第一类滤光单元3和第二类滤光单元4，其中：第一类滤光单元3允许可见光通 过且阻挡不可见光通过，第二类滤光单元4允许不可见光通过且阻挡可见光通过。

本公开实施例提供的彩膜基板1应用于显示装置时，第一类滤光单元3允许可见光通过且阻挡不可见光通过，使显示装置能够显示出供人们观看的图像信息；第二类滤光单元4允许不可见光通过且阻挡可见光通过，使显示装置能够显示出供专用设备读取且人眼不可见的机读信息；由于图像信息和机读信息不重叠，人们在观看图像信息时看不见机读信息，从而可以改善相关技术中机读信息对人眼造成的视觉混淆，从而提高显示装置的显示效果。
如图4所示，本公开的一些实施例还提供了一种显示面板，该显示面板包括阵列基板6和上述任一实施例中的彩膜基板1，阵列基板6和彩膜基板1相对设置。
显示面板还包括设置于阵列基板6和彩膜基板1之间的液晶层7、设置于阵列基板6远离液晶层7一侧的第一偏光片5，以及设置于彩膜基板1远离液晶层7一侧的第二偏光片8，其中：对应彩膜基板1的每个滤光单元，阵列基板6靠近液晶层7的一侧设置有第一电极以及分别与每个第一电极连接的多个薄膜晶体管，彩膜基板1中多个像素单元2靠近液晶层7的一侧设置有与第一电极位置相对的第二电极。

如图5所示，本公开的一些实施例还提供了一种背光模组，该背光模组 包括灯组，灯组包括多个第一光源以及多个第二光源，其中，前述多个第一光源发出可见光，前述多个第二光源发出不可见光。
本公开实施例提供的背光模组，当显示装置采用该背光模组以及实施例四的显示面板时，第一光源发出的可见光穿过第一类滤光单元3，使显示装置能够显示出供人们观看的图像信息；第二光源发出的不可见光穿过第二类滤光单元4，使显示装置能够显示出供专用设备读取且人眼不可见的机读信息；由于图像信息和机读信息不重叠，人们在观看图像信息时看不见机读信息，从而可以改善相关技术中机读信息对人眼造成的视觉混淆，提高显示装置的显示效果。
可选地，第一光源可以为第一LED灯9，第二光源可以为第二LED灯10。
在本实施例中，第二LED10灯的具体类型不限，例如可以为红外LED灯或紫外LED灯。
在本公开的实施例中，前述多个第一LED灯9和前述多个第二LED灯10的排列形式不限。例如，如图5所示，在一具体实施例中，前述多个第一LED灯9和前述多个第二LED灯10在导光板11的入光侧交替排列。在本实施例中，第一LED灯9和第二LED灯10设置于导光板11的入光侧，第一LED灯9发出的可见光和第二LED灯10发出的不可见光经导光板11射入前述实施例中的显示面板，第一类滤光单元3透过第一LED灯9发出的可见光且阻挡第二LED灯10发出的不可见光，使显示装置能够显示出供人们观看的图像信息，如图6所示；第二类滤光单元4透过第二LED灯10发出的不可见光且阻挡第一LED灯9发出的可见光，使显示装置能够显示出供专用设备读取且人眼看不见的机读信息，如图7所示。这样人们在观看图像信息时看不见机读信息，从而可以改善相关技术中机读信息对人眼造成的视觉混淆，提高显示装置的显示效果。
本公开的一些实施例还提供了一种显示装置，该显示装置包括显示面板和设置于显示面板背侧(即入光侧)的背光模组，其中：

如图5所示，背光模组包括灯组，灯组包括多个第一光源以及多个第二光源，前述多个第一光源发出可见光，前述多个第二光源发出不可见光。
本公开实施例提供的显示装置，第一光源发出的可见光穿过第一类滤光单元3，使显示装置能够显示出供人们观看的图像信息；第二光源发出的不可见光穿过第二类滤光单元4，使显示装置能够显示出供专用设备读取的机读信息；由于图像信息和机读信息不重叠，人们在观看图像信息时看不见机读信息，从而可以改善相关技术中机读信息对人眼造成的视觉混淆，提高显示装置的显示效果。
可选地，第一光源可以为第一LED灯9，第二光源可以为第二LED灯10。
在本实施例中，当第二类滤光单元4允许红外光线通过且阻挡可见光通过时，第二LED灯10包括红外LED灯；或者，当第二类滤光单元4允许紫外光线通过且阻挡可见光通过时，第二LED灯10包括紫外LED灯。
显示装置的具体类型不限，例如可以为平板显示器、平板电视、手机、平板电脑、电子书等等，这里不作具体限定。
在本实施例中，对应每个滤光单元，阵列基板6靠近液晶层7的一侧设置有第一电极以及分别与每个第一电极连接的多个薄膜晶体管，彩膜基板1中多个像素单元靠近液晶层7的一侧设置有与第一电极位置相对的第二电极。当显示装置被驱动时，背光模组的第一LED灯9发出可见光，第二LED灯10发出不可见光，光线经导光板11后射入显示面板；显示面板的第一电极和第二电极通入驱动电压后，第一电极和第二电极之间形成电场，液晶层7的液晶分子在电场的作用下进行偏转，可以使光线在穿过液晶层7时发生折射；通过调节第一电极和第二电极之间的电场，使液晶层7的液晶分子进行不同角度的偏转，从而可以改变液晶层7的透过率；光线穿过液晶层7后射入彩膜基板1，第一类滤光单元3允许可见光通过且阻挡不可见光通过，使显示装 置能够显示出供人们观看的图像信息，第二类滤光单元4允许不可见光通过且阻挡可见光通过，使显示装置能够显示出供专用设备读取且人眼看不见的机读信息。这样，人们在观看图像信息时看不见机读信息，从而可以改善相关技术中机读信息对人眼造成的视觉混淆，提高显示装置的显示效果。
如图8所示，本公开的一些实施例还提供了一种显示系统，该显示系统包括如前述实施例中的显示装置12，以及读取装置13，读取装置13包括依次设置的镜头14、光敏传感器15和处理器16，其中：镜头14用于透过显示装置12显示的不可见光；光敏传感器15用于将镜头14透过的不可见光转换为电信号并向处理器16输出；处理器16用于将电信号转换为图像信息。
本公开实施例提供的显示系统，显示装置12能够同时显示供人们观看的图像信息和供专用设备读取且人眼不可见的机读信息，读取装置13用于读取显示装置显示的机读信息；由于图像信息和机读信息不重叠，人们在观看图像信息时看不见机读信息，从而可以改善相关技术中机读信息对人眼造成的视觉混淆，提高显示系统中显示装置12的显示效果。
在本实施例中，读取装置13还包括与处理器16电连接且用于显示所述图像信息的显示设备。
具体地，当显示装置12的第二类滤光单元允许红外光线通过且阻挡可见光通过时，光敏传感器15包括红外传感器；当显示装置12的第二类滤光单元允许紫外光线通过且阻挡可见光通过时，光敏传感器15包括紫外传感器。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
