实施例二
参照图4,为本发明实施例二的液晶显示面板边缘区域结构示意图。
如图4所示,本发明提供的液晶显示面板,包括有显示区401及非显示区402,所述非显示区402设置有驱动单元,所述驱动单元包括有设置于驱动芯片绑定区403的检测模块、扇出走线区404、复用线区405以及保护电路406,所述保护电路406紧邻所述显示区401;所述保护电路406包括一扫描线,所述扫描线上连接有若干薄膜晶体管,所述薄膜晶体管的栅极连接所述扫描线,所述薄膜晶体管的源极连接于从所述扇出走线区404引出的数据线,所述,所述薄膜晶体管的漏极连接像素电极,所述保护电路406上的像素用于所述显示区401的静电防护,不用作显示画面。
所述扇出走线区404包括有若干扇出走线,所述扇出走线的输入端连接所述检测模块,所述扇出走线的输出端连接所述复用线,所述复用线连接数据线的输入端,所述数据线连接所述保护电路406中的薄膜晶体管后连接至所述显示区401的各像素。
其中,所述检测模块包括若干条检测线407,所述检测线407并联于奇偶检测信号线408,所述检测线407上连接有微型的PN结型二极管409。
在面板检测时,所述奇偶检测信号线408接受到检测信号,并将检测信号经由检测线407上的PN结型二极管409传输至相应的扇出走线,进而经由数据线对相应的像素进行充电检测,待面板检测完成,将驱动芯片绑定于非显示区402的相应位置,所述驱动芯片的管脚与所述扇出走线的连接点电性接触,将正常显示的驱动电压输入至各像素,由于PN结型二极管409具有单向导电特性,反向是截止的,正常显示的驱动信号不会反向通过所述PN结型二极管409到达奇偶检测信号线408输入端,进而驱动所述液晶显示面板显示正常画面。
依据本发明的上述目的,提出一种液晶显示装置,包括:液晶显示面板;背光模组,与所述液晶显示面板相对设置,为所述液晶显示面板提供背光;所述液晶显示面板定义为显示区及围绕于所述显示区四周的非显示区,所述非显示区内设置有驱动单元;所述驱动单元包括:若干扇出走线,所述扇出走线的输入端接入驱动信号,所述扇出走线的输出端延伸至所述显示区内,且与各像素所连接的数据线连接,用于驱动电压的传输;多条复用线,每条复用线连接部分所述扇出走线,用于控制所连接扇出走线的通断;保护电路,紧邻所述显示区,用于对所述液晶显示面板进行静电防护;以及若干检测线,所述检测线的输入端连接检测信号源,所述检测线的输出端对应连接所述扇出走线,用于对所述显示区内的电路进行检测。
本优选实施例的液晶显示装置的工作原理跟上述优选实施例的液晶显示面板的工作原理一致,具体可参考上述优选实施例的液晶显示面板的工作原理,此处不再做赘述。
本发明的有益效果为:相较于现有的液晶显示面板,本发明的液晶显示面板,通过若干检测线代替现有的面板检测电路,在实现面板检测的同时,结构简单,占用液晶面板边框的面积少,进一步实现液晶显示面板的窄边框化;解决了现有的液晶显示面板,由于面板检测电路占用边框的面积较大,导致液晶显示面板难以实现窄边框设计的技术问题。
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。
