    Abstract: A circuit which detects an output current from a pixel and an output current from an input device, and converts the output current into data is provided. The current detection circuit includes an integrator circuit, a comparator, a counter, and a latch. The integrator circuit integrates the potential of a first signal during a period determined by a second signal and outputting it as a third signal. The comparator compares the potential of the third signal with a first potential and outputting a fourth signal. The counter outputs the number of pulses included in a fifth signal as a sixth signal during a period determined by the fourth signal. The latch holds the sixth signal. The integrator circuit preferably further includes an operational amplifier and some capacitors. The first signal is supplied from a pixel included in a display device or an input portion included in an input device.

    Abstract: Two gate drivers each comprising a shift register and a demultiplexer including single conductivity type transistors are provided on left and right sides of a pixel portion. Gate lines are alternately connected to the left-side and right-side gate drivers in every M rows. The shift register includes k first unit circuits connected in cascade. The demultiplexer includes k second unit circuits to each of which a signal is input from the first unit circuit and to each of which M gate lines are connected. The second unit circuit selects one or more wirings which output an input signal from the first unit circuit among M gate lines, and outputs the signal from the first unit circuit to the selected wiring(s). Since gate signals can be output from an output of a one-stage shift register to the M gate lines, the width of the shift register can be narrowed.
