Abstract

一种感应模组的检测方法、触控芯片、触摸屏及其组装方法，所述感应模组的检测方法包括对感应模组所包含的多条互不相交的感应通道分别进行悬空采样，以得到各感应通道的第一采样数据(301)；以两个感应通道为一组，并对各组感应通道分别进行互容检测(302)，互容检测包括，对每组感应通道中的一条感应通道进行打码，并对另一条感应通道进行采样，以得到另一条感应通道的第二采样数据；其中，任意一条感应通道至少包含于其中一组感应通道中；对于存在第二采样数据的各感应通道，根据各感应通道的第二采样数据和第一采样数据，得到感应模组是否存在开路现象的检测结果。利用上述基于互容检测原理对感应模组进行检测，检测成本较低且简便易行。
