Abstract

本发明提供了一种双功能电路(10)，包括至少一个子电路单元(100)，每一子电路单元(100)通过显示面板(20)的对应数据线(30)与对应的子像素单元(100)连接；当处于测试功能时，每一子电路单元(10)将测试信号通过对应数据线(30)传输至对应的子像素单元(100)，以对相应的子像素单元(100)进行测试；当处于静电防护功能时，每一子电路单元(10)通过对应数据线(30)接收对应的子像素单元(100)的静电信号，并进行释放。本发明还提供一种显示面板及其测试方法、静电防护方法。本发明提供的双功能电路对显示面板中的子像素单元同时具有测试功能和静电防护功能，可以减少在显示面板中的器件的数量或者减少电路走线，可节省空间。
