在本实施例中,请参见图14,所述双面显示器包括第一栅极驱动电路816和第二栅极驱动电路826,所述第一栅极驱动电路816用于驱动所述第一显示面板110,所述第二栅极驱动电路826用于驱动所述第二显示面板120,所述第一栅极驱动电路816和所述第二栅极驱动电路826都位于所述弯折部150上,所述第一栅极驱动电路816靠近第一显示面板110一侧电连接第一扫描线117,所述第二栅极驱动电路826靠近第二显示面板120一侧电连接第二扫描线127,所述第一扫描线117排列在第一显示面板110上,所述第二扫描线127排列在第二显示面板120上。在本实施例中,由于只需要两个栅极驱动电路,从而可 以进一步节省成本,而且可以减小两显示面板的边框宽度,从而可以进一步增加第一显示面板110和第二显示面板120的显示区面积。另外,在本发明的其他实施例中,所述第一栅极驱动电路可以位于第一显示面板靠近弯折部一侧,所述第二栅极驱动电路可以位于第二显示面板靠近弯折部一侧。
第十实施例
图15为本发明第十实施例提供的一种双面显示器,图15的结构与图1的结构相似,因此相同的元件符号代表相同的元件,本实施例与第一实施例的主要不同点为栅极驱动电路的数量和位置。
在本实施例中,请参见图15,所述双面显示器包括共用栅极驱动电路860,所述共用栅极驱动电路860用于驱动所述第一显示面板110和所述第二显示面板120,所述共用栅极驱动电路860位于所述弯折部150上,所述共用栅极驱动电路860两侧分别电连接第一扫描线117和第二扫描线127,所述第一扫描线117排列在第一显示面板110上,所述第二扫描线127排列在第二显示面板120上。在本实施例中,由于只需要一个栅极驱动电路,从而可以进一步节省成本,而且可以减小两显示面板的边框宽度,从而可以进一步增加第一显示面板110和第二显示面板120的显示区域面积。另外,在本发明的其他实施例中,所述共用栅极驱动电路可以位于第一显示面板靠近弯折部一侧,或者所述共用栅极驱动电路也可以位于第二显示面板靠近弯折部一侧。
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:
所述双面显示器包括第一显示面板、第二显示面板和柔性电路板,所述第一显示面板和第二显示面板分别电连接柔性电路板的第一输出端和第二输出端,输送给第一显示面板和第二显示面板的信号都经由柔性电路板的输入端输入,从而接口得到了简化,安装连接也得到了简化。而且,所述双面显示器只需要一个柔性电路板,成本可以得到降低,柔性电路板的安装也比简单。
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。
