Abstract
本实用新型公开了一种内嵌式触摸屏及显示装置，将黑矩阵分割为相互绝缘且交叉设置的第一触控电极与第二触控电极，由于是对黑矩阵结构进行变更以实现触控功能，因此，可以在现有的阵列基板或对向基板的制备工艺的基础上，不需要增加额外的工艺即可制成触摸屏，节省了生产成本，提高了生产效率。并且，由于不需要单独设置ITO材料的触控电极，此外黑矩阵的图形设置在像素的非开口区域，因此可以避免触控电极对显示装置的透过率造成影响。此外，由于第一触控电极与第二触控电极是由黑矩阵分割而成，避免了第一触控电极与第二触控电极之间产生正对面积，这样，减少了由该正对面积形成的互电容，从而提高了内嵌式触摸屏的触控灵敏度。
