Abstract: An input sensing device includes sensor pixels initialized in response to a reset signal provided through a reset line, and output a sensing signal to a read-out line in response to a scan signal provided through a scan line. A controller generates at least one start signal and clock signals. A selector selectively provides the at least one start signal and the clock signals to first control lines or second control lines. A reset driver connected to the first control lines, and supplying reset signals to at least some of the reset lines based on the at least one start signal and the clock signals provided through the first control lines. A scan driver is connected to the second control lines, and supplies scan signals to at least some of the scan lines based on the at least one start signal and the clock signals.
