请参阅图 1 , 所述液晶显示面板一般包括: 薄膜晶体管 (TFT )基板 100、 与 TFT基板 00相对贴合设置的彩膜( CF )基板 300及设于 TFT基 板 100与 CF基板 300之间的液晶 500, 在 TFT基板 100与 CF基板 300 贴合完成制成液晶显示面板后, 在将该液晶显示面板组装成液晶显示装置 前, 液晶显示面板需要进行点灯检测, 以检测液晶显示面板是否有坏点
( MURA )或亮点 (DOT/UNE ) 等缺陷。 现有的液晶显示面板的点灯方 式检测一般有两种, 第一种点灯方式检测为短路棒 ( Shorting Bar )点灯方 式, 第二种点灯方式检测为 1D1G ( IData IGate, 1 数据线 1扫描线)点 灯方式, 其中, Shorting Bar 可产生红色 ( R ) 、 绿色 ( G ) 、 蓝色
( B ) 、 黑色 (Black )及白色 (White ) 的各阶灰阶(Gray ) 画面, 1D1G 可产生黑色 ( Black )及白色 ( White ) 的各阶灰阶 ( Gray ) 画面。 通常在 液晶显示面板检查的初期是使用 Shorting Bar点灯方式检测的, Shorting Bar 点灯方式检测完成后需将 Shorting Bar 端子切断, 再进行黏结
( Bonding ) 的制程。 为了检查 Shorting Bar切断后的液晶显示面板的画面 状况, 就可以使用 1D1G点灯方式检测。
请参阅图 2, 为现有的 Shorting Bar点灯方式检测的示意图, 其中, 待 检测的液晶显示面板 700 相邻的两侧设有数个短接焊盘 ( Shorting Bar Pad ) 702及键合点 ( Bonding Pad ) 704, Shorting Bar检测治具包括第 测 试臂 902、 安装于第一测试臂 902上并对应短接焊盘 702设置的数个第一 接触探针 904、 第二测试臂 906及安装于第二测试臂 906上并对应短接焊 盘 702的数个第二接触探针 908, 在本例中, 所述第一测试臂 902上设有 三个第一接触探针 904 , 用于向待检测液晶显示面板 700 传输柵极 ( Gate )信号, 第二测试臂 906 上设有两个第二接触探针 908 , 用于向待 检测液晶显示面板 700 传输数据 (Data )信号, 进而使得液晶显示面板 700显示图像。
请参阅图 3, 为现有的: ID1G点灯方式检测的示意图, 其中, 1D1G检 测治具包括第一测试臂 902,、 安装于第一测试臂 902'上并对应短接焊盘 702设置的数个第一接触探针 904 \ 安装于第一测试臂 902'上并对应键合 点 704设置的数个第一导体 905, 第二测试臂 906,、 安装于第二测试臂 906'上并对应短接焊盘 702设置的数个第二接触探针 908,、 安装于第二测 试臂 906'上并对应键合点 704设置的数个第二导体 909, 在本例中, 所述 第一测试臂 902,上设有三个第一接触探针 904'及两个第一导体 905, 用于 向待检测液晶显示面板 700传输 Gate信号, 所述第二测试臂 906,上设有 两个第二接触探针 908'及一个第二导体 909, 用于向待检测液晶显示面板 700传输 Data信号, 进而使得液晶显示面板 700显示图像。
