Description

液晶显示器及其线路架构 技术领域
本发明涉及一种液晶显示器及其线路架构， 尤指一种改良液晶面板电源 及信号提供给驱动芯片的液晶显示器及其线路架构。 龍
功能先进的显示器渐成为现今消费电子产品的重要特色， 其中液晶显示 器已经逐渐成为各种电子设备如行动电话、 个人数字助理 (PDA)、 数字相机、 计算机屏幕或笔记型计算机屏幕所广泛应用具有高分辨率彩色屏幕的显示 器。
在制造液晶显示器的过程中， 基板与驱动芯片的连接方式分为以下数种： 携带式晶粒自动接合技术 (Tape Automated Bonding, TAB), 晶粒软板接合技 术 (Chip On Film, COF) 、 晶粒玻璃接合技术 (Chip On Glass, COG)。 携带式 晶粒自动接合技术与晶粒软板接合技术都是将驱动芯片接合在软板上， 软板 再接合至玻璃基板。 而晶粒玻璃接合技术 (COG)则是直接将驱动芯片接合在 玻璃基板上。
TAB 的使用以三层结构为主， 利用聚酰亚胺 (polyimide, PI)当作基材， 使用接着剂将铜箔与聚亚酰胺贴合。在内引脚结合（inner lead bonding, ILB ) 部分是使用共晶接合 （eutectic bonding ) 技术， 再填充底胶 （Underfill dispensing) 以保护接点结构， 而外引脚结合 （outer lead bonding, OLB ) 部 份， TAB是透过胶带 (tape)与玻璃面板接合之封装方式， 目前多应用于大尺寸 的面板产品。
COF为一个两层结构的软板， 少了传统 TAB中间的接着剂层， 因此更薄 更软， 具有较佳的桡曲性。 接合方式基本上是以覆晶技术， 将一颗或多颗芯 片、 被动和主动组件等， 封装在卷带上， 以这样方式封装完成的驱动芯片,将 可成为多功能的整合型芯片组， 并可进一步缩小尺寸。
随着显像质量的提升和整体成本的考虑，驱动芯片的引脚数将大幅增加， 而线路的间距却逐渐缩小， 所以高密度的接合制程是整个驱动芯片生产流程 的关键， 所占的生产成本比重也很高， 因此如何降低成本， 将是一个重要的 课题。
请参阅图 1， 图 1为传统的面板电源及信号提供给数据驱动芯片的线路架 构图。 目前大尺寸的液晶面板 10， 在长边的驱动需要用印刷电路板 (printed circuit board, PCB)12与所有利用 COF技术接合且位于薄膜基材 16上的数据 驱动芯片 14连接在一起。 然后， 输入接口 18将时序控制器和电源控制器 (图 未示)产生的控制信号、 数据信号以及电源信号， 通过控制信号线 22a、 22b、 数据信号线 24a、 24b以及电源信号线 26a、 26b传输给各个数据驱动芯片 14 去驱动液晶面板 10。 液晶面板 10尺寸的愈大， 那么印刷电路板 12的尺寸也 要加大。但是因为印刷电路板 12制程的限制， 传统上会使用数个印刷电路板 12来连接所有的数据驱动芯片 14。 这么一来， 印刷电路板 12的大小与数量 也会随着液晶面板 10尺寸的增大而增加。 发明内容
因此，本发明的主要目的是提供 种液晶显 刷电路板和液晶面板的设计， 并减小印刷电路板的面积， 使得印刷电路板不 需要随面板尺寸的变化而变化。 而且，在传输信号一致的情况下，模块可重 用， 可以节省材料成本。

具体实施方式
请参阅图 2， 图 2是本发明实施例的液晶显示器 200的示意图。 液晶显 示器 200包含液晶面板 202、 输入接口 204、 印刷电路板 214、 数个数据驱动 芯片 216a-216c、 226a-226c、 数个扫喵驱动芯片 208、 第一薄膜基材 230、第 二薄膜基材 232以及第三薄膜基材 233。 液晶面板 202是由液晶层和导电玻 璃基板重迭组成。 第一薄膜基材 230以及第二薄膜基材 232都连接于液晶面 板 202的导电玻璃基板。 输入接口 204是用来接收时序控制器和电源控制器 (图未示)产生的控制信号、 数据信号以及电源信号。 控制信号线 240a、 240b, 数据信号线 242a、 242b以及电源信号线 244a、 244b在第一薄膜基材 230和 第二薄膜基材 232之间， 以及在每二个第二薄膜基材 232之间都是布设在液 晶面板 202的导电玻璃基板上。 因此， 控制信号、 数据信号以及电源信号经 由控制信号线 240a, 240b, 数据信号线 242a, 242b以及电源信号线 244a, 244b送予数个扫喵驱动芯片 208、数据驱动芯片 216a-216c、 226a-226c。而图 2虽然仅绘示六个数据驱动芯片 216a-216c、 226a-226c及三个扫喵驱动芯片 208，但是数据驱动芯片以及扫喵驱动芯片的数目可根据不同液晶显示器的尺 寸做调整。 第一薄膜基材 230 与印刷电路板 214 是由异方性导电胶膜 (Anisotropic Conductive Film， ACF)黍合。
数据驱动芯片 216a-216c、226a-226c以及数个扫喵驱动芯片 208是以 COF 的方式设置于第二薄膜基材 232和第三薄膜基材 233上。 液晶显示器 200采 双端驱动的方式驱动复数个数据驱动芯片 216a-216c、 226a-226c, 也就是说， 数据驱动芯片 216a-216c、 226a-226c分为第一数据驱动芯片组以及第二数据 驱动芯片组。 第一数据驱动芯片组的数个数据驱动芯片 216a-216c相互串接， 而第二数据驱动芯片组的数个数据驱动芯片 226a-226c亦串接。 第一数据驱 动芯片组的数据驱动芯片 216a耦接于输入接口 204， 而第二数据驱动芯片组 的数据驱动芯片 226a亦电性连接于输入接口 204。 输入接口 204产生的控制 信号、数据信号和电源信号会经过控制信号线 240a、数据信号线 242a以及电 源信号线 244a送给数据驱动芯片 216a后， 再依序传递给第一数据驱动芯片 组其余的数据驱动芯片 216b-216c。 类似地， 输入接口 204产生的控制信号、 数据信号和电源信号会经过控制信号线 240b、数据信号线 242b 以及电源信 号线 244b送给数据驱动芯片 226a后， 再依序传递给第二数据驱动芯片组其 余的数据驱动芯片 226b-226c。而输入接口 204产生的控制信号和电源信号则 会再传递至第三薄膜基材 233上的扫喵驱动芯片 208以启动和控制扫喵驱动 芯片 208的运作。 而第三薄膜基材 233之间的控制信号线和电源信号线也是 布设在液晶面板 202的导电玻璃基板上。
当扫喵驱动芯片 208产生扫描讯号至液晶面板 202时， 液晶面板 202每 一列的像素会依序开启， 在此同时， 输入接口 204则会发出控制信号、 电源 信号与数据信号至数据驱动芯片 216a，而数据驱动芯片 216a在接收电源信号 时会启动 (enable)并接收输入接口 204所传送的数据信号， 然后将控制信号传 至下一级的数据驱动芯片 216b。 同样地， 下一级数据驱动芯片 216b在接收 电源信号而启动时， 会接收输入接口 204所传送的数据讯号再将控制讯号传 送至下一级数据驱动芯片 216c， 同样的做法直到控制信号传送至最后一级数 据驱动芯片。 类似地， 数据驱动芯片 226a-226c 也以同样的方式传送数据信 号、 电源信号和控制信号。最终液晶面板 202接收到数据驱动芯片 216a-216c 以及 226a-226c所输出的数据讯号至一整列的像素使其充电到各自所需的电 压， 以显示不同的灰阶。
在本实施例中， 第一薄膜基材 230以及印刷电路板 214连接在数据驱动 芯片 216a-216c、 226a-226c的中间， 但是第一薄膜基材 230以及印刷电路板 214的位置也不限定于此。 在另一实施例中， 第一薄膜基材 230位于若干个 第二薄膜基材 232之间的位置是位于将控制信号以及电源信号自所述输入接 口 204 传输给所有扫描驱动芯片 208 和所有数据驱动芯片 216a-216c、 226a-226c所需时间最少的位置。 本领域的技术人员可以理解， 该所需时 间最少的位置可以在确定面板的长宽比及导线的材料等具体数据后就 确定， 这里不再进行详细论述。 举例来说， 可以先计算各个扫描驱动芯片 208和各个数据驱动芯片 216a-216c、 226a-226c之间传递信号的时间，如果信 号由输入接口 204分别传输到数据驱动芯片 226a、 226b, 216a-216c、 与从数 据驱动芯片 226c至最后一个扫描驱动芯片 208的时间是最少的，则将第一薄 膜基材 230以及印刷电路板 214连接在数据驱动芯片 226b、226c之间的位置。
由于第一薄膜基材 230 以及印刷电路板 214 连接在数据驱动芯片 216a-216c、 226a-226c的中间，所以在数据的传递上较传统液晶显示器缩短数 据传输时间， 从而可以提高面板的响应速度。
综上所述， 虽然本发明已以较佳实施例揭露如上， 但该较佳实施例并非 用以限制本发明， 该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。
