Abstract:
1. A touch input device, comprising: a substrate which is provided with an upper surface; a plurality of sensible conductive layers, all of which are configured on the upper surface of the substrate and are arranged in columns and rows; and a plurality of first switch units, which are configured on the substrate and are electrically connected with the sensible conductive layers, such that one of a step A and a step B is completed by the first switch units, and the other one of the step A and the step B is not completed by the first switch units, wherein the step A is that the sensible conductive layers of same columns conduct electrically with one another, and the step B is that the sensible conductive layers of same rows conduct electrically with one another; wherein each first switch unit includes: two transistors, one of which is connected between two neighboring sensible conductive layers of a same column of the sensible conductive layers, and the other one of which is electrically connected between two neighboring sensible conductive layers of a same row of the sensible conductive layers, with each transistor being provided with an activation end, a first output end and a first input end; and an inverter, which is provided with an output end and an input end, wherein the input end of the inverter is electrically connected with the activation end of one transistor and the output end of the inverter is electrically connected with the activation end of the other transistor.
