Abstract: A gate driver IC (i.e., gate driver circuit), when set to a first mode by a logic signal of the terminal FNC*, shifts data in the gate driver IC in synchronization with one clock cycle of a clock inputted to the terminal CLK** (clock input terminal), and outputs a selection voltage or a non-selection voltage based on a data position in the gate driver IC; and when set to a second mode by a logic signal of the terminal FNC*, shifts data in the gate driver IC in synchronization with n clock cycles (n is an integer of at least 2) of a clock inputted to the terminal CLK**, and outputs the selection voltage or the non-selection voltage based on the data position in the gate driver IC.

A second gate signal line driving unit and a first gate signal line driving unit of a first gate driving circuit apply a control voltage to the first gate signal line and the second gate signal line, respectively. The second gate signal line driving unit of a second gate driving circuit applies a control voltage to the first gate signal line. An ON voltage, a first OFF voltage, and a second OFF voltage are sequentially applied to the first gate signal line. The ON voltage and the first OFF voltage are sequentially applied to the second gate signal line.

Abstract: A display apparatus includes: display pixels arranged in rows and columns, each display pixel being disposed at the intersection of one of gate signal lines arranged in rows and one of source signal lines arranged in columns; a gate driver IC capable of selecting the gate signal lines based on a designated order; a source driver IC that outputs a voltage signal to the source signal lines; and a TCON. The display pixels each include an organic EL element, a capacitor into which the voltage signal is written, a capacitor capable of receiving an electric charge in the capacitor, and a driving transistor that supplies a driving current corresponding to the magnitude of the electric charge in the capacitor to the organic EL element. The TCON sorts the order of writing to the rows so as to reduce the difference in the voltage signal between successive rows.

A gate terminal of the first switch transistor is connected to a first gate driver circuit. Gate terminals of the second and third switch transistors are connected to a second gate driver circuit, which includes a second gate signal line connected to both the gate terminal of the second switch transistor of a Nth row and the gate terminal of the third switch transistor of a (N+1)th row.
