 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。
图2为本发明中有机显示装置的第一较佳实施例的结构示意图。
所述有机显示装置包括数据线Dn、扫描线Sn以及电源线Pn，其中n为自然数。数据线Dn用于传输显示数据信号，扫描线Sn用于传输控制信号，电源线Pn用于提供驱动电源。每个发光单元21对应一数据线Dn、一扫描线Sn以及一电源线Pn，每个发光单元21内均设置有发光二级管，譬如图2中的第一发光二极管221以及第二发光二极管222，所述第一发光二级管221和第二发光二极管222沿平行于数据线Dn的方向排列。
在本实施例中，所述有机显示装置还包括有多条第一附加扫描线S_odd以及多条第二附加扫描线S_even。第一附加扫描线S_odd位于扫描线S2n-1和扫描线S2n之间（即奇数行），而第二附加扫描线S_even位于扫描线S2n和扫描线S2n+1之间（即偶数行）。在本实施例中，第一附加扫描线S_odd对应奇数行的发光单元，而第二附加扫描线S_even对应偶数行的发光单元。第一附加扫描线S_odd与第二附加扫描线S_even交替输入扫描信号，具体请参阅下文。
在图2所示的实施例中，所述有机显示装置还包括驱动电路（图未标示），所述驱动电路用来驱动第一发光二极管221和第二发光二极管222。所述驱动电路包括第一晶体管31、第二晶体管32、第三晶体管33以及第四晶体管34。
请一并参阅图3，图3为图2的局部放大示意图。第一晶体管31的栅极311连接扫描线S2，源极312连接数据线D1，漏极313连接第二晶体管32的栅极321。第二晶体管32的源极322连接电源线P1，漏极323分别连接第三晶体管33的源极332以及第四晶体管34的源极342。第三晶体管33的栅极331连接第一附加扫描线S_odd，漏极333通过第一发光二极管221接地；第四晶体管34的栅极341连接第二附加扫描线S_even，漏极343通过第二发光二极管222接地。
请参阅图4，图4为扫描线S n、第一附加扫描线S_odd以及第二附加扫描线S_even上的扫描信号时序图，下面结合图2、图3以及图4说明本发明第一较佳实施例的工作原理。
在一个帧的周期内，第一附加扫描线S_odd与第二附加扫描线S_even交替输入扫描信号。譬如一帧时间为T，在前T/2时间内，第一附加扫描线S_odd输入高电平，第二附加扫描线S_even输入低电平，扫描线S n顺序的输入扫描信号；而在后T/2时间内，第二附加扫描线S_even输入高电平，第一附加扫描线S_odd输入低电平，扫描线S n顺序的输入扫描信号。
以在前T/2时间内为例，在t11时间内，扫描线S1输入高电平，由于扫描线S1未连接至任何电路，此时所有的发光单元均不发光。
在t12时间内，扫描线S2输入高电平，使得第一晶体管31的栅极311打开，数据线D1的数据信号能够传输至第二晶体管32，使得第二晶体管32的栅极321打开，则电源线P1的电流能够进入第二晶体管32；此时第三晶体管33对应的第一附加扫描线S_odd为高电平，则第三晶体管33的栅极331打开，因此第二晶体管32内的电流通过其漏极323进入第三晶体管33，并经第三晶体管33的漏极333进入第一有机发光二极管221，第一有机发光二极管221由于有电流通过从而发光。依次类推，位于第一行的发光单元均发光。
在t13、 t14以及后续的t1（2n-1）、t1（2n）的驱动方式与t11、 t12的驱动方式类似，不难推断出，在前T/2时间内，由于所述第一附加扫描线S_odd输入高电平，而第一附加扫描线S_odd对应奇数行的发光单元，因此奇数行的发光单元按照时序顺序发光。
在后T/2时间内，在t21时间内，扫描线S1输入高电平，由于该扫描线S1未连接至任何电路，此时所有的发光单元均不发光。
在t22时间内，扫描线S2输入高电平，使得第一晶体管31的栅极311打开，数据线D1的数据信号能够传输至第二晶体管32，使得第二晶体管32的栅极321打开，则电源线P1的电流能够进入第二晶体管32；此时第四晶体管34对应的第二附加扫描线S_even为高电平，则第四晶体管34的栅极341打开，因此第二晶体管32内的电流通过其漏极323进入第四晶体管34，并经第四晶体管34的漏极343进入第二有机发光二极管222，第二有机发光二极管222由于有电流通过从而发光。依次类推，位于第二行的发光单元均发光。
在t23、 t24以及后续的t2（2n-1）、t2（2n）的驱动方式与t21、 t22的驱动方式类似，不难推断出，在后T/2时间内，由于所述第二附加扫描线S_even输入高电平，而第二附加扫描线S_even对应偶数行的发光单元，因此偶数行的发光单元按照时序顺序发光。
本发明通过将两个发光单元共享一个驱动电路，由该驱动电路控制两个发光单元在不同时序下发光，进而使得奇数行的发光单元按照时序顺序发光，偶数行的发光单元按照时序顺序发光，且奇数行的发光单元与偶数行的发光单元交替发光。显然本发明可以减少驱动电路的数量，进而提高发光单元的开口率，而且满足了高分辨率面板的需求。
当然，上述第一较佳实施例仅以一个驱动电路驱动两个发光单元为例进行说明，在实际应用过程中，还可以通过一个电路驱动三个以及更多个的发光单元在不同时序下顺序发光，均在本发明保护的范围之内，此处不再一一列举。而且，在通过一个电路驱动多个发光单元时，均相应的设置多个附加扫描线，譬如一个驱动电路驱动三个发光单元时，需设置三组的附加扫描线，原理同上，不再赘述。
而且，在本发明中，每个驱动电路驱动的发光单元的排列顺序可以不同，在图2所示的第一较佳实施例中，同一驱动电路驱动的两个发光单元沿平行于数据线Dn的方向排列。而在一些其他实施例中，同一驱动电路驱动的两个发光单元沿平行于扫描线Sn的方向排列，譬如请参阅图5，此时在驱动电路的驱动下，位于奇数列和偶数列的发光单元交替发光，三个或者三个以上的发光单元的排列顺序类似，此处不再赘述。
本发明还提供一种显示器，譬如液晶电视或者个人手持终端，该显示器包括本发明提供的有机显示装置，鉴于该装置在上文已有详细的描述，此处不再赘述。
本发明通过将多个发光单元共享一个驱动电路，由该驱动电路控制多个发光单元在不同时序下发光，可以减少驱动电路的数量，进而提高发光单元的开口率，而且满足了高分辨率面板的需求。
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。
