为了更清楚地说明本公开文本的实施例的技术方案，下面将对实施例的附图进行简要说明，应当知道，以下描述的附图仅仅涉及本公开文本的一些实施例，而非对本公开文本的限制，其中：
图1A为根据本公开文本的实施例的阵列基板的截面示意图；
图1B为根据本公开文本的实施例的阵列基板的俯视示意图；
图2为根据本公开文本的实施例的阵列基板的示意图；

图6为根据本公开文本的实施例的触控位置识别的示意图。
具体实施方式
为了使本公开文本的实施例的目的、技术方案和优点更加清楚，下面将接合附图，对本公开文本的实施例的技术方案进行清楚、完整的描述。显然，所描述的实施例是本公开文本的一部分实施例，而不是全部的实施例。基于所描述的本公开文本的实施例，本领域技术人员在无需创造性劳动的前提下所获得的所有其他实施例，也都属于本公开文本保护的范围。
当介绍本公开文本的元素及其实施例时，除非上下文中另外明确地指出，否则在本文和所附权利要求中所使用的词语的单数形式包括复数，反之亦然。因而，当提及单数时，通常包括相应术语的复数。用语“包含”、“包括”、“含有”和“具有”旨在包括性的并且表示可以存在除所列要素之外的另外的要素。
出于下文表面描述的目的，如其在附图中被标定方向那样，术语“上”、“下”、“左”、“右”“垂直”、“水平”、“顶”、“底”及其派生词应涉及公开文本。术语“上覆”、“在……顶上”、“定位在……上”或者“定位在……顶上”意味着诸如第一结构的第一要素存在于诸如第二结构的第二要素上，其中，在第一要素和第二要素之间可存在诸如界面结构的中间要素。术语“接触”意味着连接诸如第一结构的第一要素和诸如第二结构的第二要素，而在两个要素的界面处可以有或者没有其它要素。
图1A为根据本公开文本的实施例的阵列基板的截面示意图。如图1A所示，根据本公开文本的实施例的阵列基板包括：衬底基板10、位于衬底基板10上的发光器件11、位于衬底基板10的远离发光器件11的一侧上的光感传感器12、位于发光器件11和衬底基板10之间的遮光层13。遮光层13具有以阵列形式设置的多个孔H。孔H在衬底基板10上的投影与发光器件11在衬底基板10上的投影不重叠且落在光感传感器12在衬底基板10上的投影之内。
图1B为根据本公开文本的实施例的阵列基板的俯视示意图。在图1B中，发光器件11未示出。如图1B所示，多个孔H的阵列HA包括至少两个子阵列SA。每个子阵列SA包括至少两个孔H。子阵列SA内的孔H到与该子阵列相邻的子阵列SA的孔H的距离的最小值d1大于该子阵列内的相邻两个孔H之间的距离d2。
对于本公开文本的实施例，通过孔来实现指纹成像，从而能够实现指纹识别。通过采用孔阵列来成像，能够对指纹进行分割，避免小孔成像的边缘成像模糊的问题，改善成像质量。通过指纹成像在光感传感器上的接收位置，实现指纹图像的位置识别，并将该位置作为触控位置。因此，本公开文本的实施例能将指纹成像与触控功能集成在背板内，在显示区域实现了指纹识别和触控，从而更有利于全面屏、窄边框的实现。再者，本公开文本的实施例还降低了制造成本且减小了体积。
该子阵列的孔到与该子阵列相邻的子阵列的孔的距离的最小值为该子阵列内的相邻两个孔之间的距离的两倍以上。通过这样的设置，可以避 免相邻子阵列之间产生干扰，实现更好的指纹成像效果。
图1B中示出的子阵列SA为3×3的形式是示例性的，可以根据需要来设置子阵列的行和列的数目。例如，可以将子阵列设置为10×10的形式来获得较佳的显示效果。
孔的直径需要满足小孔成像原理中对小孔直径的要求。例如，孔的直径范围为约5-20微米。当孔的直径大于20微米时，会影响所成的指纹图像的分辨精度。当孔的直径小于5微米时，会造成在光感传感器上的低照度从而影响成像效果。
发光器件可以为OLED器件。由此，对于OLED显示装置，将不需要单独提供用于指纹识别的光源，因为用于显示的OLED器件可以作为该光源。遮光层可以包括金属和任何适宜的其他遮光材料。光感传感器可以包括CCD光感传感器和CMOS感光传感器中的至少一种。衬底基板可以包括柔性基板。例如，衬底基板可以为聚酰亚胺(Polyimide，PI)基板。
需要说明，在阵列基板中可以设置一个光感传感器，也可以设置多个光感传感器。例如，可以通过各个孔在一个光感传感器的不同区域所成的像，来进行指纹识别。例如，可以通过各个孔在各自对应的传感器所成的像，来进行指纹识别。
图2为根据本公开文本的实施例的阵列基板的示意图。如图2所示，根据本公开文本的实施例的阵列基板还可以包括定位装置20。该定位装置20被配置为当触控物体30触控阵列基板时，基于触控物体30反射的光经由孔H入射到光感传感器12的入射位置，确定触控物体30的位置。
如图2所示，根据本公开文本的实施例的阵列基板还可以包括指纹识别装置40。该指纹识别装置40被配置为当触控对象30为手指时，获取来自光感传感器12上的指纹图像。
定位装置20和指纹识别装置40可以实现为处理器和存储器的组合，其中处理器执行存储器中存储的程序以实现相应单元或模块的功能。本文中描述的单元或模块也可以完全的硬件实施方式实现，包括专用集成电路(ASIC)、现场可编程门阵列(FPGA)等。
阵列基板还可以包括位于发光器件11上的覆盖层14。覆盖层14可以包括自下而上设置的第一粘合层141、偏光片142、第二粘合层143和隔离层(例如，玻璃)144。这里，“下”是指朝向衬底基板10的方向，而“上”是指远离衬底基板10的方向。
图3为根据本公开文本的实施例的显示面板的示意图。如图3所示，根据本公开文本的实施例的显示面板2000可以包括如上所述的阵列基板100和与阵列基板100相对设置的盖板200。例如，阵列基板100可以为图1A、图1B和图2中任一个所示的阵列基板。
图4为根据本公开文本的实施例的显示装置的示意图。如图4所述，根据本公开文本的实施例的显示装置3000可以包括如上所述的显示面板2000。显示面板可以为图3所示的显示面板2000。
本公开文本的实施例提供的显示装置可以为：显示面板、手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
图5为根据本公开文本的实施例的阵列基板的指纹图像。图5的左侧图像(a)为一种示例中的指纹图像，而图5的右侧图像(b)为根据本公开文本的实施例的指纹图像(其以子阵列为10×10的形式排列的孔为例子)。从图4中可以看出，根据本公开文本的实施例的指纹图像更清晰，成像质量更高。
本公开文本的实施例还提供了一种利用如上所述的阵列基板的指纹识别方法。该方法包括当触控物体为手指时，获取来自光感传感器上的指纹图像。
本公开文本的实施例还提供了一种利用如上所述的阵列基板的触控方法。该方法包括当触控物体触控阵列基板时，基于触控物体反射的光经由孔入射到光感传感器的入射位置，确定触控物体的触控位置。
光感传感器可以具有与子阵列一一对应的感测区域。根据本公开文本的实施例的触控方法包括将接收到的来自触控物体的反射光的感测区域的位置作为触控物体的触控位置。
图6为根据本公开文本的实施例的触控位置识别的示意图，其中，以手指为触控物体为示例。如图6所示，将光传感器划分为具有沿第一方向(例如，X方向)和与第一方向垂直的第二方向(例如，Y方向)的不同坐标的感测区域，例如，(x1,y1)，(x1,y3)，(x3，y2)等。根据将接收到的来自触控物体的反射光的感测区域的位置，来确定触控物体的触控位置。从而，根据触控位置识别和执行触控指令。例如，如图6所示，指纹图像(即，来自手指的反射光)所对应的感测区域为(x4，y2)。此时，将触控位置识别为(x4，y2)。然后可以根据(x4，y2)的触控位置识别和执行触控指令。可以理解，若指纹图像占据了两个或以上感测区域，则可以将指纹图像占据面积最大的区域识别为对应的感测区域。
已经描述了某特定实施例，这些实施例仅通过举例的方式展现，而且不旨在限制本公开文本的范围。事实上，本文所描述的新颖实施例可以以各种其它形式来实施；此外，可在不脱离本公开文本的精神下，做出以本文所描述的实施例的形式的各种省略、替代和改变。所附权利要求以及它们的等价物旨在覆盖落在本公开文本范围和精神内的此类形式或者修改。
