附图说明

图1为根据本发明实施例的基板的结构示意图；
图2为示出了根据本发明实施例的基板被划分为多个像素单元的示意图；
图3为根据本发明另一实施例的基板的结构示意图；
图4为根据本发明实施例的显示面板的结构示意图；
图5为根据本发明实施例的显示装置中的第一处理电路的结构框图；

图8为示出了根据本发明实施例的显示装置接收数据的示意图；以及
图9和图10示出了可以应用于根据本发明实施例的基板的光敏二极管的结构示意图。
具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
为了方便描述，本文中可使用诸如“在……下方”、“在……之下”、“下”、“在……之上”、“上”等的空间相对术语来描述附图中所示的一个元件或特征与另一元件或特征的关系。应该理解，空间相对术语旨在涵盖使用或操作中的装置的除图中所示的取向之外的不同取向。例如，如果图中的装置颠倒，则被描述为“在其它元件或特征之下”或“在其它元件或特征下方”的元件将因此被取向为“在其它元件或特征之上”。因此，术语“在……之下”可涵盖在……之上和在……之下这两个取向。装置可按照其它方式取向(旋转90度或位于其它取向)，并且将相应地解释本文所用的空间相对描述语。
图1为根据本发明实施例的基板的结构示意图，图2为示出了根据本发明实施例的基板被划分为多个像素单元的示意图。
参见图1和图2，根据本发明实施例的基板包括衬底10和设置在衬底10上的遮光件11和光敏传感层12。光敏传感层12包括至少一个光敏传感器单元121，用于检测可见光信号，并且光敏传感层12将光敏传感器单元121检测到的可见光信号转换成与该可见光信号的光强度相应的电信号。遮光件11阻挡一侧光线照射到光敏传感器单元121上。
根据本发明实施例的基板，通过设置在衬底10上的光敏传感层12可以接收从衬底10的一侧入射的可见光信号，而遮光件11可以阻挡来自衬底10的另一侧的光线照射到光敏传感层12上。光敏传感层12的光敏传感器单元121能够检测接收到的可见光信号，并将检测到的可见光信号转换成电信号。
当根据本发明的基板应用于显示面板时，该基板能够实现接收数据的功能。此外，当具有根据本发明的基板的显示面板应用于显示装置时，遮光件11可以阻挡来自背光源的光线照射到光敏传感层12上。在此情况下，遮光件11可以形成遮光区域。
根据本发明的实施例，如图2所示，将基板划分为多个像素单元13，以外基板包括位于各个像素单元13的边界处的黑矩阵。遮光件11可以是黑矩阵的一部分。
为了避免衬底10上的光敏传感层12的光敏传感器单元121接 收到显示装置自身发出的可见光信号，可以将光敏传感器单元121设置为完全位于由遮光件11形成的遮光区域中。根据本发明的实施例，光敏传感器单元121的边缘可以与对应的遮光件11的边缘对齐。此外，每个光敏传感器单元121可以对应至少一个像素单元13。
根据本发明的实施例，如图2所示，每个光敏传感器单元121对应多个像素单元13，从而增加每个光敏传感器单元121的感光面积，以避免或减小由于光敏传感器的感光范围小所造成的通信中断的问题。
如图2所示，每个光敏传感器单元121对应了多个像素单元13，并且位于由黑矩阵所形成的遮光区域。图2中的每个小格表示一个像素单元13，每个小格中的空白区域为显示区域，而由黑色线条所形成的网格表示黑矩阵。从图2中可以看出，每个光敏传感器单元121形成为网格状。
根据本发明的实施例，光敏传感层12中包括的各个光敏传感器单元121之间是彼此绝缘的，即，任意相邻两个光敏传感器单元121设置为彼此间隔。
应当理解的是，光敏传感层12中包括的各个光敏传感器单元121既可以独立工作也可以协同工作。每个光敏传感器单元121可以独立地检测到相同的可见光信号，并分别对检测到的光信号转换得到相同的电信号。此外，当可见光信号较弱，每个单独的光敏传感器单元121不足以检测到完整的可见光信号时(即，每个单独的光敏传感器单元121检测到的可见光信号的光强度不同)，各个光敏传感器单元121可协同工作，将各自检测到的不同强度的可见光信号转换成相应的电信号，以获得较完整的数据信息。这种由多个光敏传感器单元协同工作的方式提高了使用该基板的显示装置的检测灵敏度，便于获得完整的数据信息。
图3为根据本发明另一实施例的基板的结构示意图。
在图1所示的实施例中，光敏传感层12位于衬底10和遮光件11之间。与图1所示的实施例不同，如图3所示，衬底10位于光敏传感层12和遮光件11之间。
根据本发明的实施例，光敏传感器单元121可以包括光敏二极管。图9和图10示出了可以应用于根据本发明实施例的基板的光敏二极管的结构示意图。
光敏二极管可以包括2CU型光敏二极管(如图9所示)和2DU型光敏二极管(如图10所示)。参见图9和图10，2CU型光敏二极管和2DU型光敏二极管可以包括前极30和后极31。与2CU型光敏二极管相比，2DU型光敏二极管还包括环极32(环形的扩散层引出的电极)，用于减小光敏二极管的暗电流。可以根据实际需要来确定光敏二极管的型号。例如，当要求更低的功耗时可以选择2DU型光敏二极管。
根据本发明的实施例，可以在根据本发明的基板上设置彩膜层。在此情况下，所述基板可以形成为彩膜基板。
图4为根据本发明实施例的显示面板的结构示意图。
如图4所示，根据本发明实施例的显示面板可以包括阵列基板14和对盒基板。所述对盒基板可以为根据本发明的前述各实施例的基板，并且该对盒基板的光敏传感层12朝向显示面板的出光侧。因此，可以将对盒基板设置在阵列基板14的出光侧，并且将对盒基板的遮光件11设置为朝向阵列基板14。
虽然在图4中示出了采用图3所示的基本，但是也可以采用图1所示的基板。
根据本发明的显示面板可以应用于各种显示装置。所述显示装置还可以包括处理电路，用于接收由光敏传感层转换的电信号，并将接收到的电信号转换成数据信息。
由于设置了光敏传感层，因此，根据本发明的显示装置不仅可以用于显示画面，还可以用于LIFI通信。
在获得数据信息后，显示装置可以直接显示所获得的数据信息，或者对数据信息进行存储。
根据本发明的实施例，显示装置还可以包括设置在显示面板的入光侧的包括发光元件(图4中的发光元件15)的背光源。显示装置的处理电路可以构造为控制发光元件15的开关频率，以使得发光 元件15发出携带预定信息的光信号，从而实现光通信。
图5为根据本发明实施例的显示装置中的第一处理电路的结构框图，图6为示出了根据本发明实施例的显示装置发送数据的示意图。
参见图5和图6，根据本发明的显示装置的处理电路可以包括第一处理电路，其包括彼此电连接的调制电路201和发光控制电路202，并且发光控制电路202与发光元件15电连接。调制电路201将待发送数据信息转换成调制信号，并且将所述调制信号发送至发光控制电路202。发光控制模块接收所述调制信号，并根据所述调制信号控制发光元件15的开关频率。根据本发明的实施例，发光元件15可以是条形光源也可以是点光源。
图7为根据本发明实施例的显示装置中的第二处理电路的结构框图，图8为示出了根据本发明实施例的显示装置接收数据的示意图。
参见图7和图8，根据本发明的显示装置的处理电路可以包括第二处理电路，其包括彼此电连接的模数转换电路211和解调电路212。模数转换电路211可以将光敏传感器单元121接收到的电信号转换成数字信号，并将数字信号发送至解调电路212。解调电路212可以接收所述数字信号，并对所述数字信号进行解调，以得到数据信息。
根据本发明的实施例，模数转换电路211可以对任意一个光敏传感器单元121检测得到的可见光信号进行处理(即，光敏传感器单元121的独立工作模式)。可替换地，模数转换模块211可以对全部光敏传感器单元121检测得到的可见光信号进行处理(即，光敏传感器单元121的协同工作模式)。
在独立工作模式下，每个光敏传感器单元121检测到的光强度的模拟信号的值分别为A1、A2、…、An，经过模数转换后分别得到相应的数字调制信号D1、D2、…、Dn，对数字调制信号进行解调后得到数据S1、S2、…、Sn。当某一光敏传感器单元被遮挡或者接收到的光线非常微弱而无法获取解调后的数据时，在独立工作模式下，可以选取通过其他未被遮挡的光敏传感器单元获得的数据，从而确保 在部分区域被遮挡的情况下依然能够接收数据。在协同工作模式下，将各个光敏传感器单元121检测到的光强度的模拟信号的值求合，即A＝A1+A2+…+An，光强度的总和A经模数转换得到数据数字调制信号D，最终得到数据S，从而提高了显示装置作为接收端的检测灵敏度。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
