Abstract
A display panel driver includes a plurality of stages. An N-th stage of the plurality of stages is configured to output a scan signal and an emission signal synchronized with each other based on a first power voltage, a second power voltage, and at least one clock signal. N is a natural number.
Claims20
A display panel driver comprising a plurality of stages,
- wherein an N-th stage of the plurality of stages is configured to output a scan signal and an emission signal synchronized with each other based on a first power voltage, a second power voltage, and at least one clock signal, and
- wherein N is a natural number.
A display apparatus comprising:
- a display panel configured to display an image;
- a first driver comprising a plurality of stages and configured to output a scan signal and an emission signal to the display panel;
- and
- a second driver configured to output a data voltage to the display panel,
- wherein an N-th stage of the plurality of stages of the first driver is configured to output the scan signal and the emission signal synchronized with each other based on a first power voltage, a second power voltage, and at least one clock signal, and
- wherein N is a natural number.

A method of driving a display panel, comprising a plurality of pixel rows, using a display panel driver, comprising a plurality of stages, the method comprising:
- applying a clock signal and a power voltage;
- generating a scan control signal in response to the power voltage and a first scan signal that is outputted from an (N−1)-th stage;
- transmitting the clock signal, in response to the scan control signal, to a scan output node, wherein a high pulse of the clock signal pulls up a second scan signal of an N-th stage;
- outputting the second scan signal;
- generating an emission control signal in response to the scan control signal;
- transmitting the power voltage, in response to the emission control signal, to an emission output node to pull up an emission signal;
- and
- outputting the emission signal,
- wherein N is a natural number, and
- the second scan signal drives an N-th pixel row and the emission signal drives an (N−2)-th pixel row.
