Abstract
A gate driver can include a plurality of stages configured to output scan signals. An output of each stage among the plurality of stages is configured to connect to a pair of gate lines that are adjacent to each other, output an odd-numbered scan signal to an odd-numbered line among the pair of gate lines according to a first driving frequency, and output an even-numbered scan signal to an even-numbered line among the pair of gate lines according to the first driving frequency. Also, a phase difference between the odd-numbered scan signal and the even-numbered scan signal is 180 degrees.
Claims18
A gate driver, comprising:
- a plurality of stages configured to output scan signals,
- wherein an output of each stage among the plurality of stages is configured to:
- connect to a pair of gate lines that are adjacent to each other,
- output an odd-numbered scan signal to an odd-numbered line among the pair of gate lines according to a first driving frequency, and
- output an even-numbered scan signal to an even-numbered line among the pair of gate lines according to the first driving frequency, and
- wherein a phase difference between the odd-numbered scan signal and the even-numbered scan signal is 180 degrees.
A display device comprising:
- a display panel including data lines, gate lines and a plurality of sub-pixels;
- a data driver configured to supply data voltages to the data lines;
- and
- a gate driver configured to supply scan signals to the gate lines,
- wherein the gate driver includes a plurality of stages, and
- wherein an output of each stage among the plurality of stages is connected to a pair of gate lines that are adjacent to each other and configured to:
- output an odd-numbered scan signal to an odd-numbered line among the pair of gate lines, and
- output an even-numbered scan signal to an even-numbered line among the pair of gate lines, and
- wherein the odd-numbered scan signal and the even-numbered scan signal are output with a phase difference of 180 degrees.
A stage circuit for a gate driver, the stage circuit comprising:
- a start signal input circuit configured to receive at least one start signal and generate an output based on the at least one start signal;
- a switch circuit configured to receive the output from the start signal input circuit and generate an output;
- and
- an output circuit configured to, in response to receiving the output generated by the switch circuit, output an odd-numbered scan signal to a first output terminal and output an even-numbered scan signal to a second output terminal,
- wherein the odd-numbered scan signal and the even-numbered scan signal have different phases and a same frequency, and
- wherein a phase difference between the odd-numbered scan signal and the even-numbered scan signal is 180 degrees.
