其中， 该 OLED发光区域 10包括若干呈阵列分布的像素区域 101。
该扫描驱动电路 11与该 OLED发光区域 10之间通过若干扇出的扫描线 SL连 接。 该数据驱动电路 12与该 OLED发光区域 10之间通过若干扇出的数据线 DL 连接。
其中， 如图 1所示， 本发明中， 每一数据线 DL通过有机发光二极管 D1与电 压点 VP连接， 每一扫描线 SL通过有机发光二极管 D2与电压点 VP连接。 该有 机发光二极管 Dl、 D2作为静电保护元件使用， 其中， 该有机发光二极管 Dl、 D2 在数据线 DL或扫描线 SL上的静电荷积累到一定程度时， 反向连接击穿而将静电 荷传导至电压点 VP, 保证显示面板 1内部阵列免受静电伤害。
如图 2所示， 每一像素区域 101包括有机发光二极管 D、 开关晶体管 Q1以及 驱动晶体管 Q2。 其中， 开关晶体管 Q1的栅极与扫描线 SL连接， 源极与数据线 DL连接， 漏极与驱动晶体管 Q2的栅极连接。 该驱动晶体管 Q2的源极与正电压 VDD连接，漏极与该有机发光二极管 D的正极连接，该有机发光二极管 D的负极 接地。
当选通信号施加到扫描线 SL上时， 与该扫描线 SL连接的开关晶体管 Q1导 通， 从而数据线 DL的数据信号通过该导通的开关晶体管 Q1 施加在驱动晶体管 Q2的栅极上。 因此， 驱动晶体管 Q2也相应导通， 正电压 VDD通过该导通的驱动 晶体管 Q2施加驱动电压至该有机发光二极管 D而驱动该有机发光二极管 D发光。
如图 2所示， 在本发明第一实施方式中， 该数据线 DL和扫描线 SL分别通过 反向连接的有机发光二极管 D1以及有机发光二极管 D2与零电位 VSS连接。 即， 其中有机发光二极管 D1的负极连接于数据线 DL,正极接地； 有机发光二极管 D2 的负极连接于扫描线 SL, 正极接地。 从而， 在发生 ESD (静电放电， Electro-Static discharge ) 时， 即数据线 DL或扫描线 SL上的静电荷积累到一定程度时， 对应的 有机发光二极管 D1或 D2反向连接击穿而将静电荷传导至地， 保证显示面板 1内 部阵列免受静电伤害。

请参考图 4, 在本发明第三实施方式中， 数据线 DL同时通过反向连接的有机 发光二极管 D1连接零电压 VSS而接地以及通过另一正向连接的有机发光二极管 D1连接正电压 VDD。 扫描线 SL同时通过反向连接的有机发光二极管 D2连接零 电压 VSS而接地以及通过另一正向连接的有机发光二极管 D2连接正电压 VDD。 从而， 当数据线 DL上的静电荷积聚到一定程度时， 与数据线 DL连接的两个有机 发光二极管 D1反向连接击穿而分别将静电传导至地以及该正电压 VDD。 当扫描 线 SL上的静电荷积聚到一定程度时， 与扫描线 SL连接的两个有机发光二极管 D2反向连接击穿而分别将静电传导至地以及该正电压 VDD。
其中， 在本实施方式中， 该显示面板 1为 AMOLED (有源矩阵有机发光二极 管 , Active-matrix organic light-emitting diode )显示面板。
从而， 本发明中， 通过将该有机发光二极管 D2作为静电保护元件， 使得静电 无需准备少量特殊的 MOS管， 节省了成本并简化了制程。
