Abstract
An array substrate and a touch screen adopt a horizontal electric field driving mode. The array substrate with the horizontal electric field driving mode comprises a substrate, a plurality of common electrode lines formed on the substrate, and a plurality of gate lines formed on the substrate and a plurality of data lines intersecting the gate lines. The common electrode lines function as sensing electrodes or driving electrodes and the data lines or the gate lines function as the driving electrodes or the sensing electrodes during a touch period. The touch screen with the horizontal electric field driving mode can reduce the number of manufacturing processes, lower the production cost, and meanwhile, reduce the touch noise caused by a liquid crystal layer, thereby increasing the touch sensitivity efficiently.
