Abstract
A touch panel and a touch-sensitive display device are provided. The touch panel includes transversal electrode arrays and longitudinal electrode arrays with mutually perpendicular extending directions. The transversal electrode arrays and the longitudinal electrode arrays are each connected to a controller by a wire. All the wires are each serially connected with a first resistor. A sum of an owned resistance of each wire and a resistance of the first resistor serially connected with the wire constitutes an equivalent resistance, and all the equivalent resistances respectively corresponding to all the wires are equal. By the above solution, the invention can avoid the problem of inaccurate detection caused by error resulting from different wire resistances, and the detection accuracy of the touch panel is effectively improved consequently.
