下面结合附图详细介绍本实施例显示面板1的各组成部分。
如图1以及图2所示，每条扫描线11沿显示面板的长边方向延伸，若干扫描线11沿显示面板的短边方向间隔排列。扫描线11沿显示面板的长边方向延伸即扫描线11经过显示面板的短边两端。本实施例扫描线11选择金属材料，但本发明不以此为限制，扫描线11的材料还可以选择合金、金属材料的氮化物、金属材料的氧化物、金属材料的氮氧化物等导电材料。扫描线11电性连接该子像素区域内发光模块14，为与之相连的开关晶体管1411提供栅压Vselection。各扫描线11还连接至一信号选择器(未图示)，且各扫描线11通过信号选择器连接至移位寄存器系统(未图示)。移位寄存器系统在系统时钟控制下，将选通信号依次传递。选通一条扫描线11后，与该条扫描线11连接的各子像素区域内的开关晶体管打开。
每条数据线12沿显示面板的短边方向延伸，若干数据线12沿显示面板的长边方向间隔排列。数据线12沿显示面板的短边方向延伸即数据线12经过显示面板的长边两端。本实施例数据线12选择金属材料，但本发明不以此为限制，数据线12的材料还可以选择合金、金属材料的氮化物、金属材料的氧化物、金属材料的氮氧化物等导电材料。各子像素区域一侧的数据线12电性连接该子像素区域内的发光模块14，为与之相连的开关晶体管1411提供数据信号Vdata。数据线12还连接至信号接入部15，通过信号接入部15接入电信号。
每条电源线13沿显示面板的短边方向延伸，若干电源线13沿显示面板的长边方向间隔排列。电源线13沿显示面板的短边方向延伸即电源线13经过显示面板的长边两端。
本实施例电源线13选择金属材料，但本发明不以此为限制，电源线13的材料还可以选择合金、金属材料的氮化物、金属材料的氧化物、金属材料的氮氧化物等导电材料。
在显示面板中，若干电源线13与若干数据线12同层形成，且与若干扫描线11之间具有绝缘层(未图示)。各子像素区域一侧的电源线13电性连接该子像素区域内的发光模块14，为与之相连的驱动晶体管1412提供驱动电源信号Vdd。电源线13一端连接至信号接入部15，通过信号接入部15接入电信号。
在本实施例中，显示面板的短边方向的数据线12以及扫描线13和显示面板的长边方向的扫描线11交叉设置而形成的显示面板使得屏体能够正常显示。更重要的是，若干电源线13沿显示面板的短边方向延伸，由于屏体的显示面板的短边方向方向的长度较小，从而使得电源线的长度较短，这就减小了电源线上的电阻压降，进而极大地减轻了由电源线上的电阻压降导致的显示不均问题，极大地提高了屏体的显示品质。
应理解的是，本实施例为了适应现有布线方式，将若干数据线12设置成与电源线13一样沿显示面板的短边方向延伸且沿显示面板的长边方向间隔排列，而若干扫描线11设置成沿显示面板的长边方向延伸并沿显示面板的短边方向间隔排列。当然本发明不以此为限制，若干扫描线11与若干数据线12设置方式也可与本实施例不同，只要将电源线13设置成沿显示面板的短边方向延伸且显示面板的长边方向间隔排列均可。
同时，若干扫描线11与若干数据线12以及若干电源线13交叉，定义出各种颜色的子像素区域，相邻两子像素区域之间同时具有一条数据线12和一条电源线13，电源线13和数据线12彼此绝缘。可根据需要将子像素区域中的一些组合成像素区域。具体地，本实施例中，一个红色子像素区域R，一个绿色子像素区域G、一个蓝色子像素区域B形成一个像素区域(为方便理解，图2中只标注了一个像素区域，但是实际上有很多像素区域)。
同一像素区域内的各子像素区域沿显示面板的长边方向分布，具体地，红色子像素区域R、绿色子像素区域G、蓝色子像素区域B显示面板的长边方向分布，使得同一像素区域内的各子像素区域通过同一扫描线11提供栅压Vselection，同时通过多条数据线12以及多条电源线13提供数据信号Vdata以及驱动电源信号Vdd，进一步适应现有显示面板的配线方式。
当然本发明也不以此为限制，同一像素区域内的各子像素区域也可以沿显示面板的短边方向分布，此时，同一像素区域内的各子像素区域通过多条扫描线11(扫描线11条数与子像素区域数量相同)提供栅压Vselection，同时通过一条数据线12以及一条电源线13提供数据信号Vdata以及驱动电源信号Vdd。
同时，本实施例中，若干电源线13与若干数据线12交替间隔排列，以便于电路布线。当然本发明也不以此为限制，若干电源线13与若干数据线12也可不交替间隔排列。
发光模块14包括包括驱动电路结构141以及被驱动电路结构141驱动的单元发光器件142。
本实施例以2T1C结构的驱动电路结构141进行说明，但是本发明并不限于此。2T1C结构的驱动电路结构141包括开关晶体管1411、驱动晶体管1412、存储电容器1413。开关晶体管1411的栅极、源极、漏极分别电性连接扫描线11、数据线12、驱动晶体管1412的栅极。驱动晶体管1412的源极、漏极分别电性连接电源线13、单元发光器件142。存储电容器1413一端电性连接至驱动晶体管1412的栅极，其另一端电性连接至驱动晶体管1412的源极，当然本发明也不以此为限制，其他实施例中存储电容器1413的另一端还可以电性连接至驱动晶体管1412的漏极。
发光模块14工作时，开关晶体管1411的栅极被扫描信号选通时打开，其源极引入数据信号Vdata，进而通过漏极对存储电容143进行充电。而存储电容器1413在一帧的时间内维持驱动晶体管1412栅极电压的稳定。驱动 晶体管1412一般工作在饱和区，通过漏极为单元发光器件142提供的驱动电流。
本实施例显示面板为有机发光显示面板，当然本发明并不限于此，显示面板还可为其他类型，例如液晶显示面板。
信号接入部15为扫描线11、数据线12以及电源线13提电源线号。本实施例由于数据线12以及电源线13沿显示面板1的短边方向延伸，而数据线12以及电源线13条数又较多，因此将信号接入部15设置在显示面板1的长边边侧，便于走线设置。当然本发明也不以此为限制，在合理对走线进行布局的前提下，信号接入部15也可以位于显示面板1的短边边侧。这种边侧不限于短边或者长边的一侧，也可以是两侧同时供电。本发明当显示面板为柔性显示面板时，信号接入部15还可折弯到显示面板1的背部(即无显示窗口的一侧)，进而减小边框尺寸。
综上所述，与现有技术相比，本发明提供的显示面板的若干电源线沿显示面板的短边方向延伸，相较于现有技术电源线沿显示面板的长边方向延伸，有效缩短了电源线的长度，改善了电源线上的电阻压降导致的显示不均问题。
以上所述的具体实例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
