其中，最靠近显示区域的一列或一行虚拟电极包括第一部分和第二部分，其中第一部分位于显示区域，第二部分位于虚拟像素区。
其中，所述像素电极为AMOLED显示面板的阳极，对应的，所述虚拟电极为虚拟阳极。
其中，多个所述像素电极的上方分别设有有机发光层和阴极，所述阴极连接成一整面，所述阴极延伸到所述虚拟电极的上方，所述虚拟电极和所述阴极之间设有有机光阻层。
其中，所述像素电极为AMOLED显示面板的阴极，对应的，所述虚拟电 极为虚拟阴极。

在本实施例中，所述显示区域100为用户看得到的区域，所述显示区域100内设有多个像素电极110，相邻像素电极110之间彼此分离。多个像素电极110形成多行和多列像素电极110，在本实施例中，所述像素电极110包括第一像素电极111和第二像素电极112，所述第一像素电极111的面积大于所述第二像素电极112的面积。当然，在本发明的其他实施例中，像素电极110还可以只包括一种尺寸的像素电极或者包括更多种尺寸的像素电极。在本实施例中，所述第一像素电极111形成多行和多列，所述第二像素电极112也形成多行和多列，其中，多行第一像素电极111和多行第二像素电极112逐行交替排列，也即一行第一像素电极111、一行第二像素电极112、一行第一像素电极111、一行第二像素电极112、…依序逐行交替排列；多列第一像素电极111和多列第二像素电极112逐列交替排列，也即一列第一像素电极111、一列第二像素电极112、一列第一像素电极111、一列第二像素电极112、…依序逐列交替排列；。另外，在本发明的其他实施例中，多行第一像素电极和多行第二像素电极逐多行交替排列，例如，两行第一像素电极、两行第二像素电极、两行第一像素电极、两行第二像素电极、…依序逐两行交替排列；多列第一像素电极和多列第二像素电极逐多列交替排列，例如，三列第一像素电极、三列第二像素电极、三列第一像素电极、三列第二像素电极、…依序逐三列交替排列。
在本实施例中，所述非显示区域位于显示区域100的外侧且环绕所述显示区域100设置，所述非显示区域为用户看不到的区域，例如边框遮挡住的区域，在本实施例中，所述非显示区域包括虚拟像素区200和周边外围区300。
为了防止在显影、蚀刻过程中造成邻近非显示区域的像素电极110与中心 位置的电极110尺寸不一致，本实施例设置了虚拟像素区200，用于改善该问题。具体说来，在本实施例中，所述虚拟像素区200环绕所述显示区域100设置，也即所述显示区域100的上、下、左、右四侧的外侧都有虚拟像素区200。当然，在本发明的其他实施例中，所述虚拟像素区还可以只位于显示区域的上侧、下侧、左侧或右侧中的一侧、两侧或三侧，例如当位于三侧时，此时所述显示区域的另外一侧没有虚拟像素区设置。在本实施例中，虚拟像素区200包括多个虚拟电极110，至少部分所述虚拟电极210邻近靠近显示区域100边缘的像素电极110设置，具体说来，所述虚拟电极210包括第一列虚拟电极210、第二列虚拟电极210、第一行虚拟电极210、第二行虚拟电极210，所述第一列虚拟电极210邻近图1中最左侧列的像素电极110，所述第二列虚拟电极210邻近图1中最右侧列的像素电极110，第一行虚拟电极210邻近图1中最上侧行的像素电极110，所述第二虚拟电极212邻近图1中最下侧行的像素电极110。在本实施例中，所述虚拟电极210与所述像素电极110通过同一制程形成，具体为通过同一道显影、蚀刻制程同时形成像素电极110和虚拟电极210，在显影、蚀刻过程中，由于形成靠近边缘的像素电极110的金属层外侧还有形成虚拟电极210的金属层，从而蚀刻时靠近显示区域100边缘的像素电极110和靠近中心的像素电极110被蚀刻掉的金属一样或者接近一样，从而靠近显示区域100边缘的像素电极110与靠近显示区域100中心的像素电极110大小会一样或接近一样，从而AMOLED显示面板的显示比较均匀。同时，远离像素电极110一侧的虚拟电极210(也即位于虚拟像素区200外边缘的虚拟电极210)相比位于虚拟像素区200中心的虚拟电极210在蚀刻时会被蚀刻掉较多的金属，从而靠近虚拟像素区200外边缘的虚拟电极210比中心区域的虚拟电极210的尺寸要小，由于虚拟电极210被遮挡住或者虚拟电极210处不发光，从而边缘处的虚拟电极210与中心处的虚拟电极210尺寸不一致对AMOLED显示面板的显示效果没影响。从而整体而言，通过设置虚拟像素区200，AMOLED显示面板的发光均匀性比较好，显示效果也较好。
在本实施例中，周边外围区300邻近虚拟像素区200设置，所述周边外围区300位于虚拟像素区200的外侧，所述周边外围区300环绕所述虚拟像素区200设置，也即所述虚拟像素区200的四周都有周边外围区300，所述虚拟像 素区200位于显示区域100和周边外围区300之间。在本实施例中，所述周边外围区300中设有口字型的低电平电极以及一些静电释放电路等。另外，在本发明的其他实施例中，当所述虚拟像素区只位于显示区域的上侧、下侧、左侧或右侧中的一侧、两侧或三侧时，此时所述周边外围区环绕虚拟像素区和显示区域设置，也即当显示区域外侧存在虚拟像素区时，此时外围区围绕虚拟像素区设置，当显示区域外侧不存在虚拟像素区时，此时外围区直接围绕显示区域设置。
为了使位于显示区域边缘的像素电极的尺寸与位于显示区域中心的像素电极尺寸尽量一致，在本实施例中，虚拟电极210的尺寸和排列方式与相应的像素电极110的尺寸和排列方式相同。具体说来，所述虚拟电极210包括第一虚拟电极211和第二虚拟电极212，所述第一虚拟电极211的尺寸与第一像素电极111的尺寸相同，所述第二虚拟电极212的尺寸与所述第二像素电极112的尺寸相同。在本实施例中，虚拟像素区200包括多列第一虚拟电极211、多行第一虚拟电极211、多列第二虚拟电极212、多行第二虚拟电极212，其中，请参见图1，多行第一虚拟电极211与多行第一像素电极111相对应，也即多行第一虚拟电极211位于多行第一像素电极111的延长线上，多行第二虚拟电极212与多行第二像素电极112相对应，也即多行第二虚拟电极212位于多行第二像素电极112的延长线上，同样，多列第一虚拟电极211与多列第一像素电极111相对应，也即多列第一虚拟电极211位于多列第一像素电极111的延长线上，多列第二虚拟电极212与多列第二像素电极112相对应，也即多列第二虚拟电极212位于多列第二像素电极112的延长线上，而且，相邻虚拟电极210之间的间隔和位置关系与相邻像素电极110之间的间隔和位置关系相同，从而，虚拟电极210的排列方式与对应的像素电极110的排列方式完全相同。在本实施例中，由于虚拟电极210的尺寸和排列方式与相应的像素电极110的尺寸和排列方式相同，从而虚拟电极210的密度与像素电极110密度相同，从而结合显示区域100和虚拟像素区200为一整体来看，位于显示区域100边缘的像素电极110的位置与位于显示区域100中心的像素电极110的位置是一样的，也即位于显示区域100边缘的像素电极110的外侧还存在虚拟电极210，从而显影蚀刻后位于显示区域100边缘的像素电极110的尺寸与位于显示区域 100中心的像素电极110的尺寸是一样的，从而AMOLED显示面板的发光均匀性比较好，显示效果也较好。
在本实施例中，最靠近显示区域100的一行虚拟电极210包括第一部分和第二部分，其中第一部分位于显示区域100，第二部分位于虚拟像素区200，第一部分和第二部分的尺寸一样或者不一样。另外，在本发明的其他实施例中，最靠近显示区域的一列虚拟电极包括第三部分和第四部分，其中第三部分位于显示区域，第四部分位于虚拟像素区，第三部分和第四部分的尺寸一样或者不一样。
请结合参见图1和图2，在本实施例中，所述像素电极110为AMOLED显示面板的阳极，对应的，所述虚拟电极210为虚拟阳极，所述阳极与所述虚拟阳极通过同一层金属、通过同一道制程形成。在本实施例中，所述阳极的上方依序设有有机发光层(OLED)120和阴极130，所述有机发光层120对应所述阳极设置，也即所述有机发光层120也是一个一个呈阵列设置，相邻有机发光层120之间分离设置，所述阴极130连接成一整面。在本实施例中，多个有机发光层120由像素定义层140围成，所述有机发光层120填充在像素定义层140形成的孔洞中，所述像素定义层140为有机光阻。在本实施例中，所述虚拟阳极的上方为所述像素定义层140，所述虚拟阳极的上方没有设置有机发光层，从而虚拟像素区200不能发光，所述阴极延伸到所述虚拟阳极的上方。另外，在本发明的其他实施例中，所述像素电极还可以为AMOLED显示面板的阴极，对应的，所述虚拟电极为虚拟阴极，此时，AMOLED显示面板的阴极为单独的多个，而不是一整面，对应的，所述阳极为一整面，所述阴极位于所述阳极的下方。另外，在本发明的其他实施例中，所述像素电极还可以为AMOLED显示面板的阴极和阳极，从而相邻阴极之间是彼此分离设置，相邻阳极之间也是彼此分离设置，阳极与阴极对应设置，两者之间设置有机发光层。对应的，所述虚拟电极为虚拟阴极和虚拟阳极，所述虚拟阴极和虚拟阳极之间设置不发光的有机光阻。
另外，在本实施例中，所述像素电极110和虚拟电极210的下方还设置薄膜晶体管、扫描线、数据线和下基板，所述薄膜晶体管、扫描线和数据线形成在下基板上为本领域的公知常识，在此就不再赘述。在本实施例中，所述像素 电极110通过薄膜晶体管连接到对应的扫描线和数据线。
本发明实施例还提供一种AMOLED显示器，其包括上述的AMOLED显示面板。
需要说明的是，本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其它实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。对于装置实施例而言，由于其与方法实施例基本相似，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
通过上述实施例的描述，本发明具有以下优点：
由于所述AMOLED显示面板包括非显示区域，所述非显示区域包括虚拟像素区，其邻近所述显示区域设置，所述虚拟像素区包括多个虚拟电极，至少部分所述虚拟电极邻近靠近显示区域边缘的像素电极设置，所述虚拟电极与所述像素电极通过同一制程形成。从而，在显影、蚀刻形成像素电极的制程中，由于形成靠近边缘的像素电极的金属层的外侧还有形成虚拟电极的金属层，从而蚀刻时靠近边缘的像素电极和靠近中心的像素电极被蚀刻掉的部分一样或者接近一样，从而靠近边缘的像素电极与靠近中心的像素电极尺寸大小会一样或接近一样，从而AMOLED显示面板的发光比较均匀，显示效果较好。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
