本申请要求于2016年10月28日提交的、申请号为201610972558.5的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及指纹识别技术领域，具体涉及一种显示面板、显示装置和指纹识别方法。
背景技术
硅基OLED(有机发光二极管)微显示器件可以有效地提高PPI(单位面积像素数量)，但是也给基于硅基OLED的指纹识别带来问题。例如，由于在硅基上制作的OLED像素PPI非常高，sensor密度比较大，导致扫描频率增大，而实际触控点的数目有限，因此会收集到与触控信号无关的数据。此外，由于像素单元密度较高，接收线之间的距离非常小，容易产生串扰。此外，由于相邻像素单元中的sensor之间的间距较小，指纹谷脊反射的光不但会照射到与指纹按压点相对应的sensor上，还会照射到指纹按压点相邻的sensor，导致真实指纹反射的光强失真，甚至会生成错误的触控信号。
发明内容

接收单元，用于接收所述传感器感应到的指纹信号；
控制单元，在接收到指纹识别指令时，控制所述接收单元接收由第一数目的传感器中第二数目的传感器感应的指纹信号，
其中，所述第二数目的传感器中，任意两个传感器在所述第一方向和所述第二方向上不相邻。
例如，所述显示面板还包括：
M条扫描线，分别连接于M行像素单元中的传感器，用于向所述传感器传输驱动信号，

附图说明
为了更清楚地说明本发明实施例或传统技术的技术方案，下面将对实施例或传统技术描述中所需要使用的附图简单的介绍。显而易见地，下面描述中的附图是本公开的一些实施例，对于本领域普通技术人员而言，在不付出创造性劳动的前提下，还可以根据这些附图获得其他实施例。
图1示出了一种传统显示面板的结构示意图；
图2A示出了根据本发明一个实施例的一种显示面板的示意平面图；
图2B示出了根据本发明一个实施例的一种显示面板的示意剖面图；
图3示出了根据本发明另一个实施例的一种显示面板的示意剖面图；以及
图4示出了根据本发明另一个实施例的一种显示面板的结构示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明实施例的范围。
图1示出了一种传统显示面板的结构示意图。如图1所示，显示面板可以包括沿第一方向和第二方向排列的第一数目像素单元10，第一方向垂直于第二方向，每个像素单元10各自包括设置在硅基底上的显示器件101和传感器102，所述传感器102用于感应并识别指纹。当利用图1所示的传统显示面板实现指纹识别时，扫描信号逐行输入扫描线Gate1至Gate9，使得相应行像素逐行开启。接收线R1至R7同时扫描或者逐列扫描，以便收集来自所有sensor的数据。图1所示的传统技术方案进行扫描会出现一些问题。首先，由于在硅基上制作的OLED像素PPI非常高，sensor密度比较大，导致扫描频率增大，而实际触控点的数目有限，因此会收集到与触控信号无关的数据。此外，由于像素单元密度较高，接收线之间的距离非常小，容易产生串扰。此外，由于相邻像素单元 中的sensor之间的间距较小，指纹谷脊反射的光不但会照射到与指纹按压点相对应的sensor上，还会照射到指纹按压点相邻的sensor，导致真实指纹反射的光强失真，甚至会生成错误的触控信号。
图2A示出了根据本发明一个实施例的一种显示面板的示意平面图。如图2A所示，根据本发明一个实施例的一种显示面板可以包括沿第一方向和第二方向排列的第一数目的像素单元20，第一方向垂直于第二方向，每个像素单元20各自包括显示器件201和传感器202，所述传感器202用于感应并识别指纹。该显示面板还包括：M条扫描线Gate1、Gate2……Gate7，分别与M行像素单元中的传感器相连，用于向传感器传输驱动信号。接收单元包括：N条接收线R1、R2……R7，分别与N列像素单元20中的传感器202相连，用于接收由传感器感应的指纹信号，其中，M和N为大于1的整数。例如，第一方向可以是扫描线Gate1、Gate2……Gate7延伸的方向，第二方向可以是接收线R1、R2……R7延伸的方向。控制单元可以在扫描线向传感器传输驱动信号时，通过控制需要接收信号的若干条不相邻的接收线开启，和/或将不需要接收信号的若干条不相邻的接收线接地，以实现接收信号的传感器中，任意两个传感器在第一方向和第二方向上不相邻。例如，接收线可以由显示面板的数据线实现。
图2B示出了图2A所示显示面板的示意剖面图。如图2B所示，像素单元20包括：硅基底205和在硅基底205上形成的显示器件201和传感器202，传感器202优选是光电传感器；所述硅基底205上还设置有发光单元211。发光单元211发出的光由手指谷脊反射后进入所述光电传感器202，所述光电传感器根据反射光Lref的强度确定手指的指纹信息。当然也可以是其它光源出射的光线由手指谷脊反射后射入所述光电传感器，所述光电传感器根据反射光的强度确定手指的纹路信息。
硅基底5例如为掺杂有P型硅的基底。所述光电传感器202可以包括：在硅基底5上的N阱；其中所述N阱上设置有N+和P+。掺杂有P型硅的硅基底205与在硅基底205上的N阱和设置在N阱上的N+和P+共同构成光电传感器202。
例如，发光单元211可以是硅基OLED。发光单元211包括阳极212和阴极213，阳极212和阴极213之间设置有发光材料。所示阳极连接发光控制电路。该发光单元上方还设置有彩膜基板214，发光单元211发出的光线穿过所述彩膜基板后滤成不同的颜色出射。所述发光单元211出射的光线会因为手指谷脊差异形成不同光强的光，经过手指谷脊反射的光射向光电传感器，之后光电传感器根据手指谷脊反射的光线的强弱不同产生不同的光电流来确定手指的指纹信息。
图3示出了根据本发明另一个实施例的一种显示面板的示意剖面图。如图3所示，发光单元311可以是彩色发光单元。例如彩膜基板可以设置在发光单元301中，发光单元优选是OLED。发光单元301包括阳极312和阴极313，阳极312和阴极313之间设置有发光材料。发光材料与阴极313之间设置有彩膜基板314，所示阳极312连接发光控制电路。
为了更好控制每个指纹识别器件的通断，所述光电传感器可以串联有开关单元203或303。例如该开关单元是MOS开关，该MOS开关可以设置在硅基底上。
接下来将参考图2A、图2B和图3来详细描述根据本发明实施例的显示面板和使用该显示面板的指纹识别方法。
如图2A所示，控制单元在接收到指纹识别指令时，控制M条扫描线逐条向对应行传感器传输驱动信号，在M条扫描线中第m、第m+a、第m+2a、…、第m+pa条扫描线向对应行传感器传输驱动信号时，控制N条接收线中的n、第n+b、第n+2b、…、第n+qb条接收线接收对应行传感器感应的指纹信号，其中，m、n、a、b、p和q均为正整数，a≥2，b≥2，m≥1，n≥1，p≥0，q≥0，m+pa≤M，n+qb≤N。根据本实施例，由于a≥2，m≥1，那么即使m取最小值1，a取最小值2时(即第1、3、5…等第奇数条扫描线向第奇数行的传感器传输驱动信号时，接收线接收由传感器感应的信号)，也能保证被接收线接收感应信号的传感器，在接收线方向上是不相邻的。由于b≥2，n≥1，即使n取最小值1，在b取最小值2时(即扫描线向传感器传输驱动信号时，第1、3、5…等奇数列接收线接收由传感器感应的信号)，也能保证被接收线接收感应信号的传感器，在扫描线方向是不相邻的。根据本发明实施例，在第二数目的传感器中，距离最近的两个传感器也至少相隔一行或一列。可以较大程度地降低接收的指纹信号之间的串扰。此外，指纹谷脊向某个传感器反射的光，也不容易照射到与其相隔一行或一列的其他传感器上，因此可以提高接收到的指纹信号的准确率。
控制单元在接收到指纹识别指令时，逐条控制M条扫描线中第m、第m+a、第m+2a、…、第m+pa条扫描线向对应行传感器传输驱动信号。由于接收信号仅在M条扫描线中第m、第m+a、第m+2a、…、第m+pa条扫描线向对应行的传感器传输驱动信号时才接收信号，也即M条扫描线中的其他扫描线向对应行的传感器传输驱动信号时，接收线并不接收信号。因此在接收到指纹识别指令时，无需控制其他扫描线传输驱动信号。在接收到指纹识别指令时，可以仅控制M条扫描线中第m、第m+a、第m+2a、…、第m+pa条扫描线向对应行的传感器传输驱动信号，从而降低扫描频率。此外，由于传 感器相隔a行开启一行，可以降低接收线方向上传感器之间的串扰。
控制单元在接收到指纹识别指令时，控制M条扫描线逐条向对应行传感器传输驱动信号。在M条扫描线中的第奇数条扫描线向对应行的传感器传输驱动信号时，控制N条接收线中的第偶数条数据线接收由对应行的传感器感应的指纹信号。在M条扫描线中的第偶数条扫描线向对应行传感器传输驱动信号时，控制N条接收线中的第奇数条数据线接收由对应行的传感器感应的指纹信号。或者，在M条扫描线中的第奇数条扫描线向对应行传感器传输驱动信号时，控制N条接收线中的第奇数条线接收由对应行的传感器感应的指纹信号，在M条扫描线中的第偶数条扫描线向对应行的传感器传输驱动信号时，控制N条接收线中的第偶数条数据线接收由对应行的传感器感应的指纹信号。如图4所示，根据本发明实施例，对于信号被接收的传感器402’，在其扫描线和数据线方向上，最近的传感器与其相隔一个像素单元。而在对角线方向上则存在直接相邻的传感器。但是由于像素单元以矩阵排列，位于同一行或同一列的相邻像素单元之间的间距小于在对角线方向上相邻像素单元之间的间距。因此根据本实施例，可以避免指纹谷脊反射的光照射到相邻的两个传感器上，提高接收到的指纹信号的准确率，还可以提高被接收信号的传感器的数量，提高对指纹识别的精度。
本发明实施方式还提供了一种显示装置，包括上述的显示面板。其中，本发明实施方式提供的显示装置可以是笔记本电脑显示屏、液晶显示器、液晶电视、数码相框、手机、平板电脑等任何具有显示功能的产品或部件。
本发明实施例还提供了一种指纹识别方法，应用于上述的显示面板。所述方法包括：接收第一数目的传感器中第二数目的传感器感应的指纹信号，其中，第二数目的传感器中，任意两个传感器在第一方向和第二方向上不相邻。下面参考图2A、图2B、和图3对根据本发明实施例的指纹识别方法进行详细的说明。
根据本发明实施例的显示面板可以包括：M条扫描线，分别连接于M行像素单元中的传感器，用于向传感器传输驱动信号，N条接收线，分别与N列像素单元中的传感器相连，用于接收由传感器感应的指纹信号，其中，M和N为大于1的整数。第一方向可以是扫描线Gate1、Gate2……Gate7延伸的方向，第二方向可以是接收线R1、R2……R7延伸的方向。控制单元可以在扫描线向传感器传输驱动信号时，通过控制需要接收信号的若干条不相邻的接收线开启，和/或将不需要接收信号的若干条不相邻的接收线接地，以实现接收信号的传感器中，任意两个传感器在第一方向和第二方向上均不相邻。
接收由第一数目的传感器中第二数目的传感器感应的指纹信号可以包括：控制M条扫描线逐条向对应行的传感器传输驱动信号，在M条扫描线中第m、第m+a、第m+2a、…、第m+pa条扫描线向对应行的传感器传输驱动信号时，控制N条接收线中的n、第n+b、第n+2b、…、第n+qb条接收线接收由对应行的传感器感应的指纹信号，其中，m、n、a、b、p和q均为正整数，a≥2，b≥2，m≥1，n≥1，p≥0，q≥0，m+pa≤M，n+qb≤N。由于a≥2，m≥1，即使m取最小值1，a取最小值2时(即第1、3、5…等奇数条扫描线向奇数行传感器传输驱动信号时，接收信号线接收传感器感应的信号)，也能保证被接收线接收到感应信号的传感器在接收线方向上是不相邻的。此外，由于b≥2，n≥1，即使n取最小值1，在b取最小值2时(即扫描线向传感器传输驱动信号时，第1、3、5…等奇数列接收线接收传感器感应的信号)，也能保证被接收线接收到感应信号的传感器在扫描线方向是不相邻的。根据本发明实施例，在第二数目的传感器中，距离最近的两个传感器也至少相隔一行或一列。由此可以降低接收的指纹信号之间的串扰。而且指纹谷脊向某个传感器反射的光，也不容易照射到与其相隔一行或一列的其他传感器上，因此可以提高接收到的指纹信号的准确率。
接收第一数目的传感器中第二数目的传感器感应的指纹信号，包括：逐条控制M条扫描线中第m、第m+a、第m+2a、…、第m+pa条扫描线向对应行传感器传输驱动信号。根据本实施例，在接收到指纹识别指令时，可以仅控制M条扫描线中第m、第m+a、第m+2a、…、第m+pa条扫描线向对应行传感器传输驱动信号，从而降低扫描频率。而且由于传感器相隔a行开启一行，可以降低接收线方向上传感器之间的串扰。根据本发明实施例，在接收到指纹识别指令时，可以仅控制M条扫描线中第m、第m+a、第m+2a、…、第m+pa条扫描线向对应行传感器传输驱动信号，从而降低扫描频率。此外，由于传感器相隔a行开启一行，可以降低接收线方向上传感器之间的串扰。
根据本发明实施例，接收由第一数目的传感器中第二数目的传感器感应的指纹信号包括：控制M条扫描线逐条向对应行的传感器传输驱动信号，在M条扫描线中的第奇数条扫描线向对应行的传感器传输驱动信号时，控制N条接收线中第偶数条接收由对应行的传感器感应的指纹信号，在M条扫描线中的第偶数条扫描线向对应行的传感器传输驱动信号时，控制N条接收线中的第奇数条线接收由对应行的传感器感应的指纹信号；或在M条扫描线中的第奇数条扫描线向对应行的传感器传输驱动信号时，控制N条接收数据线中的第奇数条数据线接收由对应行的传感器感应的指纹信号，在M条扫描线中的第偶数条扫描线向对应行的传感器传输驱动信号时，控制N条接收线中的第偶 数条线接收由对应行的传感器感应的指纹信号。根据本发明实施例，被接收信号的传感器在其扫描线和数据线方向上，距离最近的传感器与其相隔一个像素单元。而在对角线方向上则存在直接相邻的传感器。由于像素单元矩阵排列，位于同一行或同一列的相邻像素单元之间的间距小于在对角线方向上相邻像素单元之间的间距。因此根据本发明实施例，可以避免指纹谷脊反射的光照射到相邻的两个传感器上，提高接收到的指纹信号的准确率；还可以提高被接收信号的传感器的数量，从而提高对指纹识别的精度。
根据本发明实施例的显示面板、显示装置和指纹识别方法，使得与被接收的指纹信号对应的传感器中，任意两个传感器在矩阵的第一方向和第二方向上不相邻，也即接收的指纹信号来自不相邻的传感器，因此可以降低接收的指纹信号之间的串扰，进而可以根据接收的指纹信号更准确地识别指纹。
