Abstract
A gate driving circuit and a display device using the same are discussed. The gate driving circuit according to an embodiment includes a first shift register configured to sequentially shift a gate start pulse in response to a gate shift clock and output a gate pulse shifted on a per block basis, each block including a plurality of gate lines, a second shift register configured to sequentially shift the gate start pulse in response to the gate shift clock and output a gate pulse shifted on a per gate line basis, and a controller configured to supply the gate shift clock to one of the first and second shift registers.
Claims14
A gate driving circuit comprising:
- a first shift register configured to sequentially shift a gate start pulse in response to a gate shift clock and output a gate pulse shifted on a per block basis, each block including a plurality of gate lines;
- a second shift register configured to sequentially shift the gate start pulse in response to the gate shift clock and output a gate pulse shifted on a per gate line basis;
- and
- a controller configured to supply the gate shift clock to one of the first and second shift registers.
A display device comprising:
- a display panel including a pixel array including pixels arranged in a matrix form based on a crossing structure of data lines and gate lines;
- a first shift register configured to sequentially shift a gate start pulse in response to a gate shift clock and output a gate pulse shifted on a per block basis, each block including a plurality of gate lines;
- a second shift register configured to sequentially shift the gate start pulse in response to the gate shift clock and output a gate pulse shifted on a per gate line basis;
- and
- a controller configured to supply the gate shift clock to one of the first and second shift registers.
