进一步地, 该液晶显示器还可以包括驱动电路板 5 , 驱动电路板 5可以 为印刷电路板。 驱动电路板通过第一柔性电路板 4与引线连接。 例如, 第一 子引线 301的一端与连接结构 6的一端连接,第一子引线 301的另一端与显 示区域中的栅线和 /或数据线连接, 第二子引线 302的一端与连接结构 6的 另一端连接, 第二子引线 302的另一端与第一柔性电路板 4的一端连接, 第 一柔性电路板 4的另一端与驱动电路板 5连接。
本实施例中, 可选地, 连接结构 6为第二柔性电路板, 通过第二柔性电 路板连接第一子引线 301和第二子引线 302时,可以通过芯片覆膜工艺将第 一子引线 301、 第二子引线 302分别与第二柔性电路板连接。
本实施例中, 可选地, 村底基板包括玻璃基板或者柔性材料基板。 当村 底基板为玻璃基板时, 该下基板通常用于传统的 TFT-LCD中。 当村底基板 为柔性材料基板时, 该下基板可用于柔性显示屏中。
本实施例提供的一种液晶显示器,村底基板上形成有显示区域和位于显 示区域周边的周边区域, 周边区域中形成有引线, 引线包括第一子引线和第 二子引线, 第一子引线位于村底基板的正面, 第二子引线位于村底基板的背 面, 第一子引线和第二子引线通过连接结构连接。 本发明减小了下基板上单 面引线的长度, 从而减小了周边区域的布线面积, 使得液晶显示面板实现了 窄边框结构, 同时, 本实施例的技术方案还有效提高了村底基板的利用率。
本发明中的液晶显示面板可应用于紧凑型电视(Compact TV )或者智
能型电视 ( Smart TV ) 中。
图 11为利用现有技术的液晶显示面板作拼接屏的示意图,如图 11所示, 利用现有技术的液晶显示面板作拼接屏时,相邻两液晶显示面板间会产生拼 缝 7, 且拼缝 7较宽, 尤其是在近距离看拼接屏的图像时, 由于拼缝较宽, 造成拼接屏的整体视觉效果不佳。 图 12为利用本发明的液晶显示面板作拼 接屏的示意图, 如图 12所示, 利用本发明的液晶显示面板作拼接屏时, 相 邻两液晶显示面板间会产生拼缝 7, 但是拼缝 7较窄, 无论近距离还是远距 离的看拼接屏的图像时, 其整体视觉效果都非常的好。
以上实施方式仅用于说明本公开, 而并非对本公开的限制,有关技术领 域的普通技术人员, 在不脱离本公开的精神和范围的情况下, 还可以做出各 种变化和变型, 因此所有等同的技术方案也属于本公开的范畴, 本公开的专 利保护范围应由权利要求限定。
