    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 dock signals. A selector selectively provides the at least one start signal and the dock 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.

    Abstract: A touch sensor includes: a substrate that includes active and non-active regions; driving cells disposed on the active region that extend in a first direction; sensing cells disposed on the active region that extend in a second direction that intersects the first direction; a first connection pattern that connects adjacent driving cells; a second connection pattern that connects adjacent sensing cells; and a touch driver disposed on the non-active region that includes thin film transistors that transmit a driving signal to each of the driving cells. The thin film transistor includes: a semiconductor layer; a gate electrode disposed on the semiconductor layer with a first insulating layer interposed therebetween; and source and drain electrodes connected to the semiconductor layer and spaced apart from each other. The first connection pattern is disposed in the same layer as at least one of the source or drain electrodes or the gate electrode.

    Abstract: An input sensing device includes: sensor pixels, a horizontal driver, a selection circuit, and a vertical driver. Each of the sensor pixels is connected to a plurality of driving lines and a one of a plurality of signal input lines. The horizontal driver sequentially applies a horizontal driving signal to the sensor pixels through the driving lines. The selection circuit is connected to n of the signal input lines (n is a natural number of 2 or more) and to one output line. The selection circuit sequentially outputs n sensing signals received through the n signal input lines to the one output line. The vertical driver receives the n sensing signals through the one output line. The horizontal driver applies the horizontal driving signal n times to a given one of the driving lines to correspond to the n sensing signals.
