多个所述待驱动区域20中的每行发光单元21与扫描线11对应,多个所述待驱动区域20中的每列发光单元21分别与数据线12、第一电源线13以及第二电源线14对应;在一实施方式中,多个所述待驱动区域20中的每行发光单元21与扫描线11一一对应;多个所述待驱动区域20中的每列发光单元21分别与数据线12、第一电源线13以及第二电源线14均一一对应,当然以上对应关系不限于此。
所述驱动芯片30与所述待驱动区域20对应;所述驱动芯片30分别与对应待驱动区域20中的发光单元21对应的扫描线11、数据线12以及第二电源线14连接,此外所述驱动芯片30还与对应待驱动区域20中各发光器件D2的第二端连接;所述驱动芯片30用于驱动所述待驱动区域20中的每个发光单元21。比如,在一实施方式中,发光器件D2的第一端为阳极,第二端为阴极。在一实施方式中,为了提高亮度均匀性和显示效果,所述待驱动区域20与所述驱动芯片30一一对应。
图2以所述待驱动区域20包括两行两列发光单元21,每一行发光单元21对应一扫描线11,每一列发光单元21分别对应一数据线12、一第一电源线13以及一第二电源线14为例进行说明,但是并不能对本发明构成限定。
为了提高驱动的效率,在一实施方式中,所述驱动芯片30包括四个扫描信号输入端31、四个数据信号输入端32、四个电源控制端33以及四个电源接入端34。所述扫描信号输入端31与对应的待驱动区域20所对应的(待驱动区域20中各发光器件D2对应的)扫描线11连接;所述数据信号输入端32与对应的待驱动区域20所述对应的数据线12连接;所述电源控制端33与对应的待驱动区域20中各发光器件D2的第二端连接;所述发光器件D2的第一端与对应的第一电源线13连接;所述电源接入端34与对应的待驱动区域20所对应的第二电源线14连接。其中所述第一电源线13接入的电压比如为VDD,所述第二电源线14接入的电压比如为VSS,VDD大于VSS。当然可以理解的,所述驱动芯片30也可包括两个扫描信号输入端31、两个数据信号输入端32。也即扫描信号输入端与所述待驱动区域20连接的扫描线对应,数据信号输入端与所述待驱动区域20连接的数据线对应。当然,可以理解的,扫描信号输入端31、数据信号输入端32、电源控制端33以及电源接入端34的数量不限于此,具体数量可根据实际需求设置。在一实施方式中,所述驱动芯片30为四个驱动模块的集成芯片,每个驱动模块包括第一晶体管和第二晶体管,第一晶体管和第二晶体管的具体连接方式可参见图1。当然驱动芯片30的具体结构不限于此。
在一实施方式中,为了进一步减小发光单元的面积,从而进一步提高分辨率,所述待驱动区域20包括间隙区域(图中未示出),该间隔区域由相邻两个发光单元21之间的间隙处组成,所述驱动芯片30位于所述间隙区域内。也即所述驱动芯片30与间隙区域的位置对应。在一实施方式中,为了进一步减小驱动芯片与对应的发光单元之间的连接线的长度,其中每一个待驱动区域20具有一几何中心,比如待驱动区域20为长方形,待驱动区域20的几何中心与长方形的几何中心重叠。所述驱动芯片30的位置与对应的待驱动区域20的几何中心的位置对应,从而可以减小压降,提高亮度的均匀性,当然,所述驱动芯片30的位置不限于此。
在一实施方式中,为了进一步减小驱动芯片30与数据线12和扫描线11之间的连接线的长度,与所述待驱动区域20对应的全部数据线12在设定平面上的正投影与所述驱动芯片30在所述设定平面上的正投影部分重叠;其中设定平面为所述显示面板100所在的平面;和/或与所述待驱动区域20对应的全部扫描线11在设定平面上的正投影与所述驱动30在所述设定平面上的正投影部分重叠。在一实施方式中,与所述待驱动区域20对应的多条数据线12相邻设置,且位于相邻两列发光单元21之间。与所述待驱动区域20对应的多条扫描线11相邻设置,且位于相邻两行发光单元21之间。
在一实施方式中,为了减小发光器件D2的第一端与第一电源线13之间的连接线的长度,与所述待驱动区域20对应的相邻两条第一电源线13相对于该待驱动区域20对称设置。在一实施方式中,相邻两条第二电源线14也可相对于该待驱动区域20对称设置或者设于相邻两列发光单元21之间。
尽管图2中仅示出两个待驱动区域20和两个驱动芯片30,但是并不能对对发明构成限定,本发明的待驱动区域和驱动芯片的数量可以大于等于两个。
尽管图2以所述待驱动区域20包括两行两列发光器件21,但是并不能对本发明构成限定。
比如,在另一实施方式,如图3所示,所述待驱动区域20包括3行2列发光单元21,在一实施方式中,所述待驱动区域30包括m行n列发光器件,其中m大于等于n,且n等于2,从而可以减少数据线与驱动芯片之间的连接线的长度。在其他一实施方式,所述待驱动区域20包括2行3列发光单元,在其他一实施方式,所述待驱动区域20包括4行4列发光单元等等,也即驱动芯片30可以驱动2行2列的发光单元或者更多的发光单元。当所述待驱动区域20包括两行两列发光单元21,便于减小与驱动芯片30的连接线的长度,从而降低压降,进而提高亮度的均匀性。
如图4所示,与所述待驱动区域20对应的一部分扫描线11在设定平面上的正投影与所述驱动芯片30在所述设定平面上的正投影部分重叠。比如上面两条扫描线11与所述驱动芯片30在所述设定平面上的正投影部分重叠。当然,可以理解的,在其他实施方式中,与所述待驱动区域20对应的一部分数据线12在设定平面上的正投影与所述驱动芯片30在所述设定平面上的正投影部分重叠。上述两种实施方式可以同时存在。
本发明还提供一种电子装置,包括上述任意一种显示面板。所述电子装置包括但不限定于手机、平板电脑、计算机显示器、游戏机、电视机、显示屏幕、可穿戴设备及其他具有显示功能的生活电器或家用电器等。

其中第二连接部441通过第一过孔431与所述第一连接部421连接,构成信号线,该信号线可以用作第一电源线或第二电源线。例如,第二金属层45的材料包括透明导电材料、Mo、Cu、Al以及Ti中的至少一种。优选为不易氧化的金属材料,比如Ti。
S104、在所述第二连接部441和第三连接部442上制作第二绝缘层45,对所述第二绝缘层45进行图案化处理,以分别在与所述第二连接部441对应的位置形成第二过孔451以及在与所述第三连接部442对应的位置形成开口452;
其中,所述开口452用于将第三连接部442裸露在外,所述第二过孔451用于将所述第二连接部441裸露在外。

如图6所示,所述方法还可包括:
S106、在所述第二过孔451内以及所述第二绝缘层45上制作透明导电层46,对所述透明导电层46进行图案化处理,形成连接端子461。
其中所述外界信号通过所述连接端子461接入所述第二连接部441。
所述连接端子461用于接入外界信号,比如电源电压VSS或VDD。当第二金属层44为易氧化的金属材料,比如铜时,通过在其上制作连接端子461,可以防止第二连接部441被氧化,提高了信号传输的稳定性。
在一实施方式中,驱动芯片30是通过贴片的方式固定到显示面板100上的,当然驱动芯片30的具体设置方式不限。
由于多个发光单元共用一个驱动芯片,因此可以减小发光单元的面积,提高了分辨率,此外由于不需要为每个发光单元单独设置一驱动电路,因此减少了封装次数,提高了生产效率,降低了生产成本。

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。
