A display apparatus is provided. The display apparatus includes a display module and multiple light-emitting driving circuits. Each of the light-emitting driving circuits includes a timing control circuit and a driving circuit. The timing control circuit receives multiple clock signals and a previous light-emitting timing signal to provide a light-emitting timing signal and an internal voltage. The driving circuit receives a first phase signal among multiple phase signals and the internal voltage to provide a light-emitting driving signal to the display module based on the first phase signal and the internal voltage. The phase signals all present disabled levels during a vertical blank period.

Display apparatus

A scanning drive circuit includes: a start-up circuit, activated based on a start-up signal or a previous stage output signal to pre-charge a first internal node; a logic gate operating based on the start-up signal or the previous stage output signal and a first output signal to control a second voltage at a second internal node; a pull-down circuit determining whether to pull down a first voltage of the first internal node based on the second voltage of the second internal node; and a plurality of output circuits pre-charging a third internal node based on the first voltage of the first internal node and generating a plurality of output signals based on a scanning clock signal or a plurality of clock signals, and further determining whether to pull down the output signals based on the second voltage of the second internal node.

Scan drive circuit

A display device and a driving method thereof are provided. In the display device, a display panel has multiple first pixel rows and multiple second pixel rows arranged alternately. In a first time interval, a first gate driver sequentially drives the first pixel rows using a first driving method. In a second time interval, a second gate driver sequentially drives the second pixel rows using the first driving method. In a third time interval, a third gate driver sequentially drives the first pixel rows using a second driving method. In a fourth time interval, a fourth gate driver sequentially drives the second pixel rows using the second driving method. One of the first driving method and the second driving method is a pulse amplitude modulation driving method, and the other of the first driving method and the second driving method is a pulse width modulation driving method.

Display device and driving method thereof

A display panel is provided. The display panel includes a display array and a plurality of shift registers. The display array is disposed in an active region. The shift registers are disposed in the active region, and configured to drive the display panel. Each shift register is divided into a plurality of sub-circuits including a first sub-circuit and a second sub-circuit. The first sub-circuit is disposed in a first column of the display array. All first sub-circuits disposed in the first column are coupled to at least one global signal line. The second sub-circuit is disposed in a second column of the display array. The second sub-circuit disposed in the second column are serially coupled as at least one string through a plurality of jump signal lines.
