Description

显示面板及其驱动方法和显示装置
技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板及其驱动方法和显示装置。
背景技术
对于现有的显示装置而言，有机发光二极管(Organic LightEmitting Diode，OLED)作为一种电流型发光器件，因其所具有的自发光、快速响应、宽视角和可制作在柔性衬底上等特点而越来越多地被应用于高性能显示领域当中。
如图1所示为现有技术中的一种OLED产品的示意图，驱动像素的电路(包括红色驱动电路、绿色驱动电路和蓝色驱动电路)一般设置在显示屏的顶部，并通过每一列的工作电压线为该列像素的像素补偿电路提供工作电压。但是，由于工作电压线本身存在一定的线阻，这样会导致压降的产生，对于距离驱动电路较近的像素单元，其亮度较高，而远离驱动电路的像素单元，亮度较低，造成了显示亮度不均匀的问题。
发明内容
本发明的目的是提出一种能够使显示亮度均匀的OLED显示面板以及驱动显示面板的方法。
本发明提供了一种显示面板，包括两组像素驱动电路；且每一种基色的每两个相邻像素列中，一个像素列的工作电压线接入第一组像素驱动电路，接入点位于像素阵列的第一行像素所在的一侧；另一个像素列的工作电压线接入第二组像素驱动电路，接入点位于像素阵列的最后一行像素所在的一侧。
优选的，第一组像素驱动电路设置在所述显示面板中第一行像素所在的一侧；第二组像素驱动电路设置在所述显示面板中最后一行像素所在的一侧。
优选的，每一种基色的各个奇数像素列的工作电压线接入到第一组像素驱动电路，各个偶数像素列的工作电压线接入到第二组像素驱动电路；或者，
每一种基色的各个偶数像素列的工作电压线接入到第一组像素驱动电路，各个奇数像素列的工作电压线接入到第二组像素驱动电路。
优选的，所述显示面板包括N种基色，每一组像素驱动电路包括N个子驱动电路；第一组像素驱动电路中的每一个子驱动电路与一种基色的各个奇数像素列的工作电压线相连，第二组像素驱动电路中的每一个子驱动电路与一种基色的各个偶数像素列的工作电压线相连；其中，N≥3。
优选的，所述N的取值为3，3种基色分别为红色、绿色、蓝色。
优选的，所述显示面板为有源矩阵有机发光二极体面板AMOLED面板。
本发明还提供了一种显示面板的驱动方法，包括：
在显示面板中设置两组像素驱动电路；
对于所述显示面板的每一种基色的每两个相邻像素列，将其中一个像素列的工作电压线接入到第一组像素驱动电路，接入点位于像素阵列的第一行像素所在的一侧；将另一个像素列的工作电压线接入第二组像素驱动电路，接入点位于像素阵列的最后一行像素所在的一侧；
使两组像素驱动电路向接入的工作电压线提供相同的工作电压。
进一步的，对于所述显示面板的每一种基色的每两个相邻像素列，将其中一个像素列的工作电压线接入到第一组像素驱动电路，将另一个像素列的工作电压线接入第二组像素驱动电路，具体包括：针对显示面板的每一种基色，
将其各个奇数像素列的工作电压线接入第一组像素驱动电路，将其各个偶数像素列的工作电压线接入第二组像素驱动电路；或者，
将其各个奇数像素列的工作电压线接入第二组像素驱动电路，将其各个偶数像素列的工作电压线接入第一组像素驱动电路。
本发明还提供了一种显示装置，包括上述任一项所述的显示面板。
本发明提供的显示面板，包括两组像素驱动电路；且每一种基色的每两个相邻像素列中，一个像素列的工作电压线接入第一组像素驱动电路，接入点位于像素阵列的第一行像素所在的一侧；另一个像素列的工作电压线接入第二组像素驱动电路，接入点位于像素阵列的最后一行像素所在的一侧。这样在每一行的位置，属于同一基色的任意两个相邻像素到像素驱动电路的距离的和都是一个定值，则由于到像素驱动电路的距离最终决定像素的工作电压，则所述的两个相邻像素的工作电压之和为定值，使得属于同一基色的任意两个相邻像素对应的两个发光元件的亮度之和相等，从而使整个显示面板的显示亮度均匀。
附图说明
图1为现有技术中的显示面板的结构示意图；
图2为本发明提供的显示面板的结构示意图。
具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
本发明提供了一种显示面板，如图2所示，包括两组像素驱动电路110和120以及阵列基板，阵列基板上形成有像素阵列200，像素阵列200包括不同基色(红色、绿色、蓝色)的像素列，每个像素列中包含多个对应于该基色的亚像素单元(图2中示出的是包含15个像素列，每一个像素列包含5行亚像素单元的一种情况，其中，211-215为红色像素列、221-225为绿色像素列、231-235为蓝色像素列；当然实际应用中，像素列的数目要远大于15列，且行数原大于5行，但是其实现原理与图2中的一致，本发明仅结合图2进行说明)；每一种基色的任意两个相邻的像素列中，有一个像素列的工作电压线接入第一组像素驱动电路110，接入点位于像素阵列的第一行(第一行)像素所在的一侧；另一个像素列的工作电压线接入第二组像素驱动电路120，接入点位于像素阵列的最后一行(第五行)像素所在的一侧；以红色像素列为例，像素列211、213、215的工作电压线接入驱动电路110，且接入点位于第一行像素所在的一侧，即第一行像素的上方；像素列212、214的工作电压线接入驱动电路120，且接入点位于第五行像素所在的一侧，即第五行像素的下方。
本发明中工作电压线与各个像素的像素补偿电路的连接方式与现有技术中一致，如图1或2所示，一个像素列的各个像素的像素补偿电路通过并联方式连接到该像素列的工作电压线。
结合图2对本发明的原理进行说明，假设两个像素驱动单元分别提供初始电压为ELVDD1和ELVDD2的工作电压，并假设经过一个像素后工作电压下降△V，则对于接入第一像素驱动单元100的所有的第M行像素，其工作电压为ELVDD1-(M-1)△V(比如图中的奇数列像素，其第1、2、3、4、5行的工作电压为ELVDD1、ELVDD1-△V、ELVDD1-2△V、ELVDD1-3△V、ELVDD1-4△V)，相应的对于接入第二像素驱动单元的所有的第M行像素，其工作电压为ELVDD2-(5-M)△V(比如图中的偶数列像素，其第1、2、3、4、5行的工作电压为(ELVDD2-4△V、ELVDD2-3△V、ELVDD2-2△V、ELVDD2-△V、ELVDD2)，而由于任意两个在行方向上相邻的同一颜色的亚像素单元，会分别接入第一像素驱动电路和第二像素驱动电路，则相邻的同一颜色的两个亚像素单元对应的工作电压之和为：
V0＝ELVDD1-(M-1)△V+ELVDD2-(5-M)△V＝ELVDD1+ELVDD2-4△V。
也就是说任意两个在行方向上相邻的同一颜色的亚像素单元，其工作电压之和为与其行数无关的定值。这样，在发光显示时，任意两个在行方向上相邻的同一颜色的亚像素单元的亮度之和会维持为恒定值。从而保证了显示面板发光的均匀性。
优选的，如图2所示，第一组像素驱动电路110设置在显示面板中第一行像素所在的一侧，第二组像素驱动电路120设置在显示面板中最后一行像素所在的一侧。
这样做的好处是，一方面可以将驱动电路分开布置，降低显示面板的厚度，另一方面可以尽可能的使像素驱动电路靠近所驱动的像素列，减少在传输线路上的压降，进而降低损耗。
不难理解，不管将第一像素驱动电路和第二像素驱动电路设置在哪个位置，各行中两个相邻的同一颜色的亚像素单元的工作电压之和都是相等的，本发明实施例优选的实施方式并不应理解为对本发明保护范围的限定。
优选的，如图2所示，每一种基色的各个奇数像素列接入到第一组像素驱动电路110，各个偶数像素列接入到第二组像素驱动电路120。
通过这种方式，能够实现工艺的同一，降低显示面板的制作难度。当然实际应用中，各个基色的奇数(偶数)列所接入的像素驱动电路也可以不相同。比如，红色像素的奇数列可以接入第一像素驱动电路，偶数列接入第二像素驱动电路；同时将蓝色和绿色像素的奇数列都接入第二像素驱动电路，偶数列可以接入第一像素驱动电路，只要同一基色的相邻两个像素列的工作电压线分别从第一行像素的一侧和最后一行像素的一侧接入不同的像素驱动电路，都可以实现本发明的技术方案。
优选的，如图2所示，显示面板包括3种基色，每一组像素驱动电路包括3个子驱动电路，即红色驱动电路、绿色驱动电路和蓝色驱动电路；第一组像素驱动电路中的每一个子驱动电路的工作电压线与一种基色的各个奇数像素列相连，第二组像素驱动电路中的每一个子驱动电路的工作电压线与一种基色的各个偶数像素列相连。
当然实际应用中，N也可以取其他大于3的值，本发明提供的技术方案对于四基色或者其他多基色显示面板同样适用。
优选的，所述显示面板为有源矩阵有机发光二极体面板AMOLED(Active-matrix organic light-emitting diode，有源矩阵有机发光二极体或主动矩阵有机发光二极体)面板。
基于相同的构思，本发明还提供了一种驱动显示面板的方法，包括：
步骤S1，在显示面板中设置两组像素驱动电路；
步骤S2，对于所述显示面板的每一种基色的每两个相邻像素列，将其中一个像素列的工作电压线接入到第一组像素驱动电路，接入点位于像素阵列的第一行像素所在的一侧；将另一个像素列的工作电压线接入第二组像素驱动电路，接入点位于像素阵列的最后一行像素所在的一侧；
步骤S3，使两组像素驱动电路向接入的工作电压线提供相同的工作电压。
优选的，所述步骤S2具体包括：针对显示面板的每一种基色，
将其各个奇数像素列的工作电压线接入第一组像素驱动电路，将其各个偶数像素列的工作电压线接入第二组像素驱动电路；或者，
将其各个奇数像素列的工作电压线接入第二组像素驱动电路，将其各个偶数像素列的工作电压线接入第一组像素驱动电路。
本发明还提供了一种显示装置，包括上述任一项所述的显示面板。
这里的显示装置可以为：电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
