A color cathode-ray tube includes a panel portion, a neck portion, a funnel portion connecting the panel and neck portions, a fluorescent layer formed on an inner surface of a face plate of the panel portion, a shadow mask disposed opposite to the fluorescent layer, an electron gun housed in the neck portion, and an internal magnetic shield disposed in the funnel portion. The resistor chain comprises a plurality of conductive electrodes that to form overlap resistors therebetween. Pressure at a touch location on the waveguide gives rise to a touch event causes the waveguide to bend or flex.
