上述触摸传感器的制作方法包括以下步骤:
步骤 101 , 在基板 1上沉积金属层, 并利用掩模板对金属层进行第一次 构图工艺, 得到金属桥(Metal Bridge ) 2。 另外, 还得到压合( bonding ) 区 域的金属层(未图示), 所述压合区域是指连接柔性电路板 ( FPC )的区域。
步骤 102,在经过步骤 101的基板 1上沉积第一绝缘层 3 ,并利用掩模板 对第一绝缘层 3进行第二次构图工艺, 使得在第一绝缘层 3上形成接触孔, 这些接触孔使各自下方的金属桥 2暴露出来。 另外, 在这次构图工艺中, 压 合区域的第一绝缘层 3被刻蚀掉以露出压合区域的金属层。
步骤 103 , 在经过步骤 102的基板 1上沉积透明导电层, 并利用掩模板 对透明导电层进行第三次构图工艺 ,得到 X方向的触摸感应层 4和 Y方向的 触摸感应层 4,。 另外, 还得到压合区域的覆盖在金属层上的透明导电层, 该 相互接触的金属层和导电层用于连接柔性电路板(FPC ) , 以导通触摸传感 器及具有触摸屏的液晶显示器中的薄膜晶体管液晶显示器(TFT-LCD )。 透 明导电层的材料为氧化铟锡(ITO ) 。
从图 1可以看出, X方向的触摸感应层 4是断开的, 其通过金属桥 2进 行连接从而被导通; 而 Y方向的触摸感应层 4,自身直接导通;
这里, X方向指平行于纸面的方向; Y方向指垂直于纸面的方向。 X方 向和 Y方向相互垂直, 但 X方向的触摸感应层 4 和 Y方向的触摸感应层 4' 不接触。
步骤 104,在经过步骤 103的基板 1上沉积第二绝缘层 5,并利用掩模板 对第二绝缘层 5进行第四次构图工艺,以得到保护 X方向和 Y方向的触摸感 应层的第二绝缘层 5。 至此, 触摸传感器制作完成。
由以上流程可以看出, 传统技术制作触摸感应器需要利用四张掩模板进 行四次构图工艺, 因此制作步骤比较多, 制作成本比较高。 发明内容
