Abstract
An object of the present invention is to efficiently reduce the number of signal lines of a control port and an input port of a sensor switch required for controlling a touch by supplying a programmable voltage from a touch drive IC TDI, not a separate external voltage source, as a voltage applied to a touch sensor. The present invention provides a touch screen which is capable of implementing low power consumption, low-resistance signal wiring, touch IC price reduction, and the like by forming a switching transistor of the sensor switch only with a P-type transistor manufactured in a Low Temperature Poly Silicon (LTPS) process, and driving the switching transistor without using a negative voltage (−V).
