Abstract: The first shift register applies (4n−3)-th and (4n−2)-th gate signals to (4n−3)-th and (4n−2)-th gate lines, respectively, in response to a first clock signal, a second clock signal having a delayed phase by 1H time with respect to the first clock signal, and a third clock signal having opposite phase to the first clock signal. The second shift register applies (4n−1)-th and 4n-th gate signals to (4n−1)-th and 4n-th gate lines, respectively, in response to the first clock signal, the third clock signal, and a fourth clock signal having opposite phase to the second clock signal. Therefore, a number of transistors in the first and second shift registers may be reduced.

Abstract: In a touch sensing display device, a plurality of sensor scanning lines extend in a first direction and sequentially receive a first voltage, and a plurality of sensor data lines extend in a second, different, direction. A plurality of sensing elements are formed in regions defined by the sensor scanning lines and the sensor data lines, and each sensing element transmits the first voltage from a corresponding sensor scanning line to a corresponding sensor data line responsive to an external touch. A sensing signal processor converts voltages of the sensor data lines into sensing data, and, a touch determining unit processes the sensing data corresponding to the sensor scanning lines by at least one scanning line to determine positions of touch regions generated during at least one frame.

Abstract: A shift register includes a plurality of stages each generating an output signal in sequence and including a buffering section, a driving section, a first charging section, and a charging control section.

The first charging section includes a first terminal electrically connected to the driving section and a second terminal electrically connected to a first source voltage. The charging control section applies the output signal of a next stage to the first charging section. Therefore, a gradual failure of TFT is reduced.
