Description
本发明属于显示技术领域，具体地讲，涉及一种显示面板及具有该显示面板的显示装置。
近年来，有机发光二极管(Organic Light-Emitting Diode，OLED)显示面板成为国内外非常热门的新兴平面显示面板产品，这是因为OLED显示面板具有自发光、广视角、短反应时间、高发光效率、广色域、薄厚度、可制作大尺寸与可挠曲的显示面板及制程简单等特性，而且它还具有低成本的潜力。
在OLED显示面板中，AMOLED显示面板是柔性显示重点发展方向之一，但是其亮度均匀性和残像仍然是它目前面临的两个主要问题，而IR压降(IR-Drop)就是造成这两个问题的因素之一。由于电源线(由金属制成)存在电阻，因此电流流经时就会导致电压存在一定的压降，称之为IR压降。IR压降会导致在靠近电源线的输入端和远离电源线的输入端的位置存在电压的差异。而OLED器件上的电流跟电源线的电压相关，这样IR压降就会导致连接电源线不同的区域的OLED器件上的电流存在差异，最终表现为显示面板的发光不均匀，从而影响显示面板的显示质量，所以在显示面板设计时，电源线上的IR压降是需要考量的因素之一。
图1是现有的AMOLED显示面板的电源线的分布示意图。如图1所示，芯片1的两端分别具有产生正极电压Vdd的正极电源端2和产生负极电压Vss的负极电源端3，正极电源线21连接到正极电源端2并延伸到显示面板的显示区内，多条正极电源线21平行排列，负极电源线31连接到负极电源端3并延伸到显示面板的非显示区内。如上所述，由于正极电源线21和负极电源线31上存在电压的差异，因此不同区域的OLED器件上的电流存在差异，AMOLED显示面板的发光不均匀，从而影响AMOLED显示面板的显示质量。

以接收向第一子显示区111内的有机发光二极管OLED传送的第一电源电压。此外，该第一电源线310连接到第一子显示区111内的有机发光二极管OLED的阴极，以将第一电源电压提供给第一子显示区111内的有机发光二极管OLED的阴极。

第三子显示区113的左右两侧的左侧非显示区123和右侧非显示区124分别设置第三电源线330，该第三电源线330穿过第一子显示区111的侧边的非显示区和第二子显示区112的侧边的非显示区(左侧对应左侧，右侧对应右侧)而连接到芯片200的第三电源端Vss3，以接收向第三子显示区113内的有机发光二极管OLED传送的第三电源电压，其中，第三电源线330、第二电源线320和第一电源线310彼此独立。此外，该第三电源线320连接到第三子显示区112内的有机发光二极管OLED的阴极，以将第三电源电压提供给第三子显示区112内的有机发光二极管OLED的阴极。
如背景技术中所述，电源电压在传送时，由于相应的电源线存在电阻，因此由电源端输出的电源电压和有机发光二极管OLED接收到的电源电压不同。此外，由于各电源线长短不同，其电阻也不同，因此连接不同电源线的不同区域的有机发光二极管OLED接收到的电源电压也不同。而在本实施例中，可以
综合考虑这些条件，在分区提供电源电压的前提下，通过模拟或者实验测试使芯片的各个电源端输出最佳的电源电压，从而使显示面板上所有的有机发光二极管OLED接收到相同的电源电压，进而消除显示面板的IR压降(IR-Drop)现象。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
