    Abstract: A multi-touch capacitive touch sensor panel can be created using a substrate with column and row traces formed on either side of the substrate. To shield the column (sense) traces from the effects of capacitive coupling from a modulated Vcom layer in an adjacent liquid crystal display (LCD) or any source of capacitive coupling, the row traces can be widened to shield the column traces, and the row traces can be placed closer to the LCD. In particular, the rows can be widened so that there is spacing of about 30 microns between adjacent row traces. In this manner, the row traces can serve the dual functions of driving the touch sensor panel, and also the function of shielding the more sensitive column (sense) traces from the effects of capacitive coupling.

    Abstract translation: 可以使用在衬底的任一侧上形成有列和行迹线的衬底来创建多点触摸电容式触摸传感器面板。 为了屏蔽来自相邻液晶显示器(LCD)或任何电容耦合源的调制Vcom层的电容耦合效应的列(感测)迹线,可以扩大行迹线以屏蔽列迹线,并且行 迹线可以靠近LCD放置。 特别地,可以加宽行,使得在相邻行迹线之间存在约30微米的间隔。 以这种方式,行迹线可以用于驱动触摸传感器面板的双重功能,以及屏蔽更敏感的列(感测)迹线与电容耦合效应的功能。
