图3为本发明3D显示系统的优选实施例的驱动示意图。
 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
在图中，结构相似的单元是以相同标号表示。
请参照图2，图2为本发明的3D显示系统的优选实施例的显示单元和控制电路的结构示意图。本优选实施例的3D显示系统包括OLED显示面板以及3D快门眼镜。OLED显示面板包括电源23、多条数据线（图中未示出）、多条扫描线（图中未示出）、多个像素单元21以及控制电路22。数据线用于传输数据信号；扫描线用于传输扫描信号；像素单元21由数据线和扫描线限定形成，用于根据数据信号以及扫描信号进行像素显示；该像素单元21包括与数据线连接的数据信号输入端24，与扫描线连接的扫描信号输入端25、与电源23连接的电源信号输入端OVDD以及用于进行像素显示的有机发光部OLED。控制电路22用于根据控制信号，对电源信号输入端OVDD的电源电压进行控制，以使得像素单元21显示左眼画面或右眼画面。3D快门眼镜（图中未示出）具有左眼快门以及右眼快门，当左眼快门完全打开时，像素单元21显示左眼画面，当右眼快门完全打开时，像素单元21显示右眼画面。
控制电路22包括第一开关管T1以及第二开关管T2。第一开关管T1的控制端输入控制信号，第一开关管T1的输入端与第二开关管T2的控制端连接，第一开关管T1的输出端接地GND。第二开关管T2的输入端与电源23连接，第二开关管T2的输出端与相应的像素单元21的电源信号输入端OVDD连接。在本优选实施例中，所述第一开关管T1为NPN型三极管，所述第二开关管T2为PMOS管。
像素单元21包括第三开关管T3和第四开关管T4，第三开关管T3的输入端通过数据信号输入端24与相应的数据线连接，第三开关管T3的控制端通过扫描信号输入端25与相应的扫描线连接，第三开关管T3的输出端与第四开关管T4的控制端连接。第四开关管T4的输入端与所述电源信号输入端OVDD连接，第四开关管T4的输出端与有机发光部OLED连接。
本优选实施例的3D显示系统使用时，请参照图3，图3为本发明3D显示系统的优选实施例的驱动示意图。像素单元21通过数据线传输的数据信号来显示左眼画面或右眼画面，其中左眼画面包括用于进行像素显示的左眼数据画面301以及用于防止串扰的左眼黑色画面302，右眼画面包括用于进行像素显示的右眼数据画面303以及用于防止串扰的右眼黑色画面304。左眼黑色画面302在相应的左眼数据画面301显示之后，相应的右眼数据画面303显示之前进行显示；右眼黑色画面304在相应的右眼数据画面303显示之后，相应的左眼数据画面301显示之前进行显示。
同时在左眼画面和相应的右眼画面之间还设置有第一空白间隔305，即左眼画面的左眼数据画面301和相应的右眼画面的右眼黑色画面304之间设置有第一空白间隔305，左眼画面的左眼黑色画面302和相应的左眼画面的右眼数据画面303之间也设置有第一空白间隔305。在所述第一空白间隔内，所述控制信号为低电平，所述电源与所述电源信号输入端断开。
在左眼数据画面301和相应的左眼黑色画面302之间设置有第二空白间隔306，在右眼数据画面303和相应的右眼黑色画面304之间设置有第二空白间隔306。在所述第二空白间隔内，所述控制信号为高电平，所述电源通过所述第二开关管与所述电源信号输入端连接。
左眼黑色画面302、右眼黑色画面304、第一空白间隔305以及第二空白间隔306的设置可以进一步地防止串扰现象的发生。
本优选实施例的3D显示系统使用时，每个左眼数据画面301、左眼黑色画面302、右眼数据画面303以及右眼黑色画面304均通过启动信号STV进行触发。
结合图2，当像素单元21开始显示左眼数据画面301时，3D快门眼镜的左眼快门32打开，3D快门眼镜的右眼快门33关闭。为了防止左眼数据画面301通过右眼快门33进入到用户的右眼，控制电路22的控制信号34设置为低电平，控制电路22的第一开关管T1断开，电源23直接输入到第二开关管T2的控制端，这时第二开关管T2断开，电源23与像素单元21的电源信号输入端OVDD断开，像素单元21的第四开关管T4的输入端由于没有输入电源电流，因此像素单元21的有机发光部OLED停止工作，避免了串扰现象的发生。
当3D快门眼镜的左眼快门32完全打开后，3D快门眼镜的右眼快门33完全关闭，这时左眼数据画面301不会通过右眼快门33进入到用户的右眼。这时控制电路22的控制信号34设置为高电平，控制电路33的第一开关管T1导通，第二开关管T2的控制端通过第一开关管T1接地GND，这时第二开关管T2导通，电源23通过第二开关管T2与电源信号输入端OVDD连接，像素单元21的有机发光部OLED开始工作，像素单元21在数据信号和扫描信号的作用下显示左眼画面。
当像素单元21开始显示右眼数据画面303时，3D快门眼镜的右眼快门33打开，3D快门眼镜的左眼快门32关闭。为了防止右眼数据画面303通过左眼快门32进入到用户的左眼，控制电路22的控制信号34设置为低电平，控制电路22的第一开关管T1断开，电源23直接输入到第二开关管T2的控制端，这时第二开关管T2断开，电源23与像素单元21的电源信号输入端OVDD断开，像素单元21的第四开关管T4的输入端由于没有输入电源电流，因此像素单元21的有机发光部OLED停止工作，避免了串扰现象的发生。
当3D快门眼镜的右眼快门33完全打开后，3D快门眼镜的左眼快门32完全关闭，这时右眼数据画面303不会通过左眼快门32进入到用户的左眼。这时控制电路22的控制信号34设置为高电平，控制电路33的第一开关管T1导通，第二开关管T2的控制端通过第一开关管T1接地GND，这时第二开关管T2导通，电源23通过第二开关管T2与电源信号输入端OVDD连接，像素单元21的有机发光部OLED开始工作，像素单元21在数据信号和扫描信号的作用下显示右眼画面。
当像素单元21开始显示左眼黑色画面302或右眼黑色画面304时，控制电路22的控制信号34继续设置为高电平，该左眼黑色画面302和右眼黑色画面304不会对左眼数据画面301或右眼数据画面303的显示造成影响。同时该控制信号34持续设置为高电平，可以减少相邻的控制信号34的高电平的间隔时间，即将控制信号设置为低电平的时间，从而提高了该控制电路22的稳定性。
这样即完成了本优选实施例的3D显示系统的3D画面的显示过程。
本发明的3D显示系统通过控制电路对像素单元的电源电压进行控制，避免了串扰现象的发生，提升了画面显示品质；解决了现有的3D显示系统易发生串扰现象的技术问题。
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。
