19. A touch sensor device, comprising:
-
at least one terminal connected to at least one contact pad; at least one common terminal; at least one light emitter connected between the common terminal and the terminal; a touch sensor and light-emitting device controller unit recognizing a signal applied to the terminal and generating a touch detection signal in response to a first control signal, and controlling a current to flow through a selected terminal in response to a second control signal; and a controller generating the first and second control signals. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
