Abstract
A touch-sensitive screen and a resistance touch-sensitive device using the same, wherein said screen comprises: an insulating substrate, a rectangular conducting layer formed on said insulating substrate, a conducting layer electrode array formed on the four edges of said conducting layer, a conductive coat formed on said conducting layer, and a conductive coat electrode wherein, at least 3 pairs of the conducting layer electrodes are deployed in said conducting layer electrode array; each pair of the conducting layer electrodes are deployed on the parallel edges of the conducting layer symmetrically; and the conducting layer electrode is set on each edge of the conducting layer. As the conducting layer electrodes are deployed symmetrically on the parallel edges of the conducting layer, the electric filed lines tends to be evenly distributed when the voltage is loaded onto the edges of the conducting layer; thus the linearity of the equipotential lines is enhanced.
