Description

触摸屏及其控制方法和显示装置 技术领域
本发明涉及触摸显示技术领域，具体地，涉及一种触摸屏及其控制方法和显示装置。
背景技术
目前，指纹识别技术开始应用在移动设备上，如应用在手机上。这一非常时尚的技术预计在密码和移动支付领域引领一场新的革命。
指纹识别技术在手机触摸屏上应用的工作原理为：先由指纹采集单元采集指纹，然后将采集的指纹生成指纹图像，后续经过对指纹图像进行处理，提取指纹特征点，最后将指纹特征点与存储在手机中的指纹认证信息进行对比，对比结果一致时，该触摸屏解锁，或该触摸屏可进行下一步操作。
但目前的指纹识别通常是将指纹识别装置设置在手机显示屏之外的特定位置上，如手机的某个功能按键上或手机屏后盖板的某个特定位置上，所以手指指纹只能对手机上的该特定位置进行触控，这虽然对指纹触控驱动芯片的功能和处理速度要求较低，但使得通过指纹对手机的触控受到了很大的空间和方向上的限制，触控起来手指的自由度受限，不能灵活自如地进行指纹触控。
发明内容
本发明针对现有技术中存在的上述技术问题，提供一种触摸屏及其控制方法和显示装置。该触摸屏通过将指纹识别元件设置在触控区域，能使指纹触控该触摸屏时更加方便和自由，不再拘泥于触摸屏之外的某一个按键，从而不仅使指纹对该触摸屏的触控更加灵活自如，而且还能使用户有更好的触控体验，同时还提高了触摸屏的触控效率。
根据本发明的一个方面，提供一种触摸屏，其包括触控区域，所述触控区域用于进行触控显示，所述触控区域内设置有多个指纹识 别元件，所述指纹识别元件用于对指纹进行识别。所述触控区域包括多个子区域，位于每个子区域内的指纹识别元件对该子区域内的指纹或指纹局部单独进行识别。
根据本发明的实施例，每个子区域的大小可以为容纳一个手指指纹的大小。
根据本发明的实施例，每个子区域可以设置有第一控制单元，其在子区域内的各个指纹识别元件当中选择N个指纹识别元件进行指纹检测。当所选择的N个指纹识别元件中的至少一个指纹识别元件检测到有指纹时，所述第一控制单元可以控制子区域内的所有指纹识别元件进行指纹检测。当所选择的N个指纹识别元件中没有任何指纹识别元件检测到有指纹时，所述第一控制单元可以控制子区域内的其他指纹识别元件不再进行指纹检测。
根据本发明的实施例，所述N个指纹识别元件可以均匀分布在子区域内，9≤N≤12，且N为整数。
根据本发明的实施例，所述触控区域可以设置有第二控制单元，其用于提取由各子区域提供的指纹检测信息，以获得最终的指纹识别信息。

具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面通过结合附图的具体实施方式对本发明所提供的触摸屏及其控制方法和显示装置作进一步详细描述。
图1示意地示出了根据本发明实施例的触摸屏的触控区域，并且图2为将图1中触摸屏的触控区域划分为子区域的示意图。
如图1所示，根据本发明实施例的触摸屏包括触控区域1，触控区域1内设置有多个用于对指纹进行识别的指纹识别元件2。
通过将指纹识别元件2设置在触控区域1，能使指纹触控该触摸屏时更加方便和自由，不再拘泥于触摸屏之外的某一个按键，从而不仅使指纹对该触摸屏的触控更加灵活自如，而且还能通过更好的用户体验。
触控区域1用于进行触控显示，可以是触摸屏的整个触控面。根据本发明的实施例，指纹识别元件2的分辨率可以在500dpi以上，指纹识别元件2的分辨率反映了指纹识别元件2的分布密度。如此设 置，能够确保指纹识别元件2对指纹的识别精度更高，从而使触控区域1对指纹的识别更加精确和清楚。需要说明的是，本发明对指纹识别元件2的分辨率范围不做限制，只要能够完成指纹识别即可。
可替换地，触控区域1也可以是触摸屏的触控面的局部。
根据本发明的实施例，如图2所示，触控区域1包括多个子区域11，位于每个子区域11内的指纹识别元件2对该子区域11内的指纹或指纹局部进行单独识别。
根据本发明的一个实施例，各个子区域11的大小形状相同，子区域11的大小可以为容纳一个手指指纹的大小(例如，1.5cm×1.5cm)。如此设置，不仅使整个触控区域1都能够进行指纹触控，而且能够提高指纹触控在空间和方向上的自由度，即，各个子区域11可以相互独立工作。从而不仅提高了整个触控区域1的触控效率，而且还提高了指纹触控的灵活自由度，改善了用户体验。
根据本发明的实施例，每个子区域11可以设置有第一控制单元(图中未示出)，用于在子区域11内的各个指纹识别元件2当中选择N个指纹识别元件2进行指纹检测。当所选择的N个指纹识别元件2中至少有一个指纹识别元件2检测到有指纹时，第一控制单元控制子区域11内的所有指纹识别元件2进行指纹检测。当所选择的N个指纹识别元件2中没有任何指纹识别元件2检测到有指纹时，第一控制单元控制子区域11内的其他指纹识别元件2不再进行指纹检测。也就是说，各个子区域11的第一控制单元可以独立地控制各个子区域11是否进行指纹检测。
位于子区域11内的N个指纹识别元件2均匀分布在子区域11，从而在最大程度上使得落到子区域11内的指纹部分不被漏检，提高了指纹识别的完整性和准确性。
通过将整个触控区域1划分为多个子区域11，在进行检测指纹时，指纹通常只落在一个或少数的几个子区域11内。通过子区域11内所选择的N个指纹识别元件2进行初步的指纹检测，当N个指纹识别元件2中没有任何指纹识别元件2检测到有指纹时，可以判定该子区域11内未落入指纹。在第一控制单元的控制下，对于未落入指纹 的子区域11不再进行指纹检测，而仅对落入有指纹的子区域11进行指纹检测，从而可以提高检测效率并节省检测指纹所需的功耗。
考虑到子区域11的大小为容纳一个手指指纹的大小，经过实验测定，N的取值范围可以为9≤N≤12，既可以确保落入每个子区域11内的指纹或指纹局部不被漏检，又可以确保检测效率的提高和功耗的节省。
根据本发明的实施例，整个触控区域1可以设置有第二控制单元(图中未示出)，用于提取由各个子区域11提供的指纹检测信息，以获得最终的指纹识别信息。最终的指纹识别信息是由触控区域1得到的完整的指纹信息。
图3至图5为当指纹位于不同数量的子区域内的示意图，并且图6为根据本发明实施例的提取指纹检测信息的流程图。
参见图3至图5和图6，当指纹3仅位于一个子区域11内时(如图3所示)，第二控制单元提取该子区域11内的指纹检测信作为所获得的最终的指纹识别信息。
当指纹3位于两个子区域11时(如图4所示)，第二控制单元对位于两个子区域11中的指纹3的面积进行比较，当位于两个子区域11中的指纹3的面积差的绝对值与指纹3总面积的比值大于设定阈值时(例如，当面积差的绝对值与指纹3总面积的比值大于20％时)，第二控制单元仅提取指纹面积较大的部分的子区域11内的指纹检测信息，以获得最终的指纹识别信息；当面积差的绝对值与指纹3总面积的比值小于或等于设定阈值时(例如，当面积差的绝对值与指纹3总面积的比值小于或等于20％时)，第二控制单元提取两个子区域11的指纹检测信息并汇总，以获得最终的指纹识别信息。需要说明的是，在指纹3位于两个子区域11的情况下，当位于两个子区域11中的指纹3的面积差的绝对值大于指纹3总面积的20％时，通过指纹3的面积较大部分的信息足以能够对该指纹3进行识别。
当指纹3位于三个或三个以上子区域11时，第二控制单元提取具有指纹的各个子区域11的指纹检测信息并汇总，以获得最终的指纹识别信息。
根据本发明的实施例，触摸屏还可以包括连接至第二控制单元的认证单元(图中未示出)，用于将通过第二控制单元获得的最终的指纹识别信息与存储在认证单元中的指纹认证信息进行对比。在对比结果为最终的指纹识别信息与指纹认证信息一致时，可以允许提供该最终的指纹识别信息的用户对触摸屏进行触摸操作。根据本发明的实施例，一种可行的操作方式是，为了避免指纹检测操作与触控操作之间的干扰，在进行指纹识别时，可以暂停触摸屏的触控功能，并且在指纹识别通过后重新恢复触控功能。
根据本发明的实施例，各个指纹识别元件2均连接至第二控制单元，并且每个指纹识别元件2可以包括指纹识别电极。在指纹识别电极与按压在其上的手指之间可以形成电容信号，并且基于所形成的电容信号可以形成指纹图像。因此，可以将指纹识别电极与按压在其上的手指之间形成的电容信号作为指纹检测信息，并且将基于指纹检测信息形成的指纹图案作为最终的指纹识别信息。
图7为电容式指纹采集的原理示意图。如图7所示，指纹3凸凹不平，当指纹3接近指纹识别电极21时，由于指纹3的凸点和凹点与各个指纹识别电极21之间的距离不同，所以形成的电容的大小也不同。根据不同位置处的各个电容的大小(即，经由各个指纹识别电极21检测到的指纹检测信息)，可以生成指纹3的图像，以作为最终的指纹识别信息。
根据本发明的实施例，指纹识别电极21可以采用触摸屏的触控电极。根据本发明的实施例，触摸屏可以包括呈矩阵排布的多行多列触控电极。触控电极采用透明导电材料制成。
需要说明的是，由于对于触控操作的检测精度不需要精确到对于指纹进行检测的精度，因此在触控时段内，对于形成为多行多列的触控电极，可以间隔n行来采集触摸信号以降低触控时的功耗，其中8≤n≤10，且n为整数。
可替换地，指纹识别电极21也可以不复用触控电极，而是另外形成在触摸屏上。
根据本发明的实施例，指纹识别电极21的形状可以为矩形，其 边长的尺寸范围可以为50-200μm。可以通过喷墨打印的方式制备形成指纹识别电极21。通过喷墨打印方式形成的指纹识别电极21能够满足较高的精度，从而使上述尺寸范围内的指纹识别电极21能够对指纹3进行精确的检测。
图8为将图1中触摸屏的触控区域划分为片区的示意图。
根据本发明的实施例，如图8所示，触控区域1可以包括提供不同的触控功能的多个片区12，每个片区12内分布有多个子区域11中的一部分子区域。可以在认证单元中存储对应于各个片区12的指纹认证信息。也就是说，触控区域1划分为提供不同的触控功能的多个片区，并且针对每一片区单独进行指纹认证。例如，如图8所示，触控区域1划分为四个片区12。在各个片区12内进行触控可以提供不同的功能，例如，触控上部的片区12可以提供模式切换功能，触控左部片区可以提供应用选择功能，触控右部区域可以提供设置功能，并且触控下部区域可以提供通信功能。应当认识到，上述各种功能以及划分片区的数量仅仅是示例性的，本发明不限于所描述的各种功能、片区数量以及片区的划分方式。
根据本发明的实施例，认证单元针对不同的片区12可以存储不同的指纹认证信息，因此，可以针对各个片区12单独地进行指纹认证。例如，针对提供设置功能的右部片区12的指纹认证信息与针对其他片区12的指纹认证信息可以是不同的。因而，可以为特定用户单独提供进行特定操作的权限。将触控区域划分为多个片区12，能够使伴随有指纹认证的触控操作更加智能化，同时还可提高安全性。
图9为根据本发明实施例的触摸屏的控制方法的流程图。
根据本发明的实施例的触摸屏的控制方法包括：通过位于每个子区域内的指纹识别元件对该子区域内的指纹或指纹局部单独进行识别；以及通过所述触控区域进行触控显示。
如图9所示，在子区域内的各个指纹识别元件当中选择N个指纹识别元件进行指纹检测(步骤S1)。判断所选择的N个指纹识别元件中是否有检测到指纹的指纹识别元件(步骤S2)。当所选择的N个指纹识别元件中的至少一个指纹识别元件检测到有指纹时(步骤 S2的“是”)，针对子区域内的所有指纹识别元件进行指纹检测(步骤S3)；当所选择的N个指纹识别元件中没有任何指纹识别元件检测到有指纹时(步骤S2的“否”)，针对子区域内的其他指纹识别元件不再进行指纹检测(步骤S4)。提取由各子区域提供的指纹检测信息，以获得最终的指纹识别信息(步骤S5)。将最终的指纹识别信息与存储的指纹认证信息进行对比(步骤S6)。当对比结果一致时，可以允许用户对触摸屏进行触摸操作；当对比结果不一致时，可禁止用户对触摸屏进行触摸操作。
具体地，步骤S5可以包括：当指纹仅位于一个子区域内时，提取该子区域内的指纹检测信息，以获得所述最终的指纹识别信息；当指纹位于两个子区域时，对位于两个子区域中的指纹的面积进行比较，当位于两个子区域中的指纹的面积差的绝对值与指纹总面积的比值大于设定阈值时，仅提取指纹面积较大的部分的子区域内的指纹检测信息，以获得所述最终的指纹识别信息，当所述面积差的绝对值与指纹总面积的比值小于或等于设定阈值时，提取两个子区域的指纹检测信息并汇总，以获得所述最终的指纹识别信息；以及当指纹位于三个或三个以上子区域时，提取具有指纹的各个子区域的指纹检测信息并汇总，以获得所述最终的指纹识别信息。
根据本发明的实施例的控制方法还可以包括步骤：将所述触控区域划分为提供不同的触控功能的多个片区，其中，每个片区内分布有所述多个子区域中的一部分子区域；以及针对每个片区单独进行指纹认证。
根据本发明的触摸屏可以应用于各种显示装置。所述显示装置包括(但不限于)：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有触控显示功能的产品或部件。
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。
