Abstract

Embodiments of the present disclosure relate to the technical field of touch control display, and an array substrate and a touch control display device are provided. The array substrate includes a plurality of touch emitting lines and a plurality of touch sensing lines arranged perpendicular to each other and isolated from each other, each of the touch emitting lines and each of the touch sensing lines form a touch sensing capacitor. The touch sensing can be realized by sensing a variation in the capacitance value of the touch sensing capacitor when touch occurs. Meanwhile, the projection of each of the touch emitting lines or each of the touch sensing lines on the substrate falls into the projection of gate lines or data lines on the substrate, thus the aperture ratio of the touch control display device is increased.
