如图5C所示，该第三阴极区块1013和该第四阴极区块1014于第二导体层1044在显示装置的所在层中电性连接，即，该第二导体层1044中设有第三导体块10441，该第三导体块10441与第二导体层1044上的第四导体块10442相隔离，该第三阴极区块1013和该第四阴极区块1014通过第三导体块10441电性连接，具体地，第三阴极区块1013和该第四阴极区块1014均通过第一传导部1032、第二传导部1033、第二导体块10422与第三导体块10423与第三导体块10441电性连接。
第三阴极区块1013和第四阴极区块1014中的任意一者产生触摸感应信号的方式与上述第一阴极区块1011和第二阴极区块1012中的任意一者产生触摸感应信号的方式类似。
参考图2至图7，图6为本发明的显示装置显示图像暨触摸感应的方法的功能时序图，图7为本发明的显示装置显示图像暨触摸感应的方法的流程图。本发明的显示装置显示图像暨触摸感应的方法是应用在图2至图5（图5A、图5B和图5C）的显示装置上。时间T0至时间T12为一个周期时间，时间T0至时间T11为该周期时间内的图像显示时间，时间T11至时间T12为该周期时间内的触摸感应时间，时间T12至时间T22为一个周期时间，时间T12至时间T21为该周期时间内的图像显示时间，时间T21至时间T22为该周期时间内的触摸感应时间，如此类推。本发明的显示装置在图像显示时间内显示图像，在触摸感应的时间内感应用户的触摸操作并产生触摸感应信号。图像显示时间和触摸感应时间均小于周期时间，图像显示时间与触摸感应时间之和等于周期时间。
如图7所示，在步骤701，控制单元20设定一个周期时间内的图像显示时间和触摸感应时间。在步骤702，控制单元20产生图像显示数据、第一控制信号和第二控制信号，该图像显示数据用于提供给显示面板10显示图像，第一控制信号用于控制显示面板10在图像显示时间到达时显示图像，第二控制信号用于控制显示面板10在触摸感应时间到达时感应用户的触摸操作并产生触摸感应信号。在步骤703，控制单元20在显示时间到达时向显示面板10输出图像显示数据和第一控制信号。在步骤704，显示面板10在图像显示时间内根据该图像显示数据和第一控制信号显示图像，具体地，在图像显示时间内，本发明的显示装置的阴极层101、有机发光二极管层102、阳极层103和薄膜晶体管阵列层104的组合在第一控制信号的控制下根据该图像显示数据显示图像。在步骤705，控制单元20在触摸感应时间到达时向显示面板10输出第二控制信号并接受该显示面板10的反馈信号（触摸感应信号）。在步骤706，显示面板10在触摸感应时间内在该第二控制信号的控制下感应用户的触摸操作，根据用户的触摸操作产生触摸感应信号，并将该触摸感应信号发送给该控制单元20，具体地，在触摸感应时间内，本发明的显示装置的第一阴极区块1011、第二阴极区块1012中的任意一者在用户的触摸操作下会产生一异常电流，该异常电流即为触摸感应信号。在步骤707，控制单元20接收该显示面板10发送的触摸感应信号，通过对该触摸感应信号的解析，控制单元20即可计算出用户在显示面板10上触摸的位置。
传统的有源矩阵有机发光二极管显示面板10不具备触摸感应功能，本发明的显示装置整合了图像显示功能和触摸感应功能，与传统的有源矩阵有机发光二极管显示面板10相比，本发明的显示装置既可以实现图像显示又可以实现触摸感应，而传统的有源矩阵有机发光二极管显示面板10需要在其上上额外增加一层触控面板才能实现触控感应功能。
在本发明中，为了实现在显示面板10上既可以实现图像显示又可以实现触摸感应，控制单元20为显示面板10设定一个周期时间内的图像显示时间和触摸感应时间，控制单元20控制显示面板10在图像显示时间内显示图像，以及在触摸感应时间内感应用户的触摸操作。
相对于传统的叠加触控面板的有源矩阵有机发光二极管显示面板10而言，本发明的显示装置由于在显示面板10上集成了图像显示功能和触摸感应功能，因此提升了生产良率，无需叠加触控面板，因此提高了显示面板10的穿透率，从而提高了显示面板10的显示品质，另外，减去了叠加的触控面板的电耗，本发明的显示装置的耗能相对于传统的有源矩阵有机发光二极管显示面板10而言要低。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
