A gate driver circuit including seven transistors and two capacitors is provided. A first end of a third transistor is coupled to a first pulse signal, a second end of the third transistor outputs a gate signal, and a control end of the third transistor is coupled to a first end of a second transistor. A first end of a fourth transistor is coupled to the second end of the third transistor, a second end of the fourth transistor is coupled to a first voltage, and a control end of the fourth transistor is coupled to a control end of the second transistor. A first end of a fifth transistor is coupled to a second voltage, a second end of the fifth transistor is coupled to the control end of the fourth transistor, and a control end of the fifth transistor is coupled to a second pulse signal.

Gate driver circuit

An e-paper display apparatus includes an e-paper display panel including multiple source lines, multiple gate selection lines, and multiple pixel circuits and a driver circuit coupled to the e-paper display panel and configured to output a driving signal to the gate selection line. The gate selection lines and the source lines are disposed along a first direction. The source lines corresponding to the gate selection line simultaneously receive respective data signals when the gate selection line is turned on. The driving signal includes a first period and a second period. The gate selection line is turned on during the first period, and the gate selection line is turned off during the second period. A time length of the first period is greater than a time length of the second period.
