Abstract
A shift register and a touch display apparatus thereof are provided. The shift register includes a voltage setting unit, a driving unit, a control unit, a discharge unit, a first compensation transistor, and a second compensation transistor. The voltage setting unit sets a terminal voltage of an internal terminal. The driving unit is coupled to the internal terminal to provide a gate signal and a driving signal. The control unit receives the terminal voltage to provide a control signal. The discharge unit discharges the terminal voltage and the gate signal according to the control signal. The first compensation transistor and the second compensation transistor are coupled in series between a touch enable signal and the internal terminal, and control terminals of the first compensation transistor and the second compensation transistor receive the terminal voltage and the touch enable signal, respectively.
