Abstract
A display device includes; a signal controller which outputs a master image signal having first data information and second data information, a master data driver which samples the first data information and the second data information from the master image signal using a first sampling clock signal, generates a slave clock signal using the master image signal, and generates a slave image signal, which corresponds to the second data information, using the slave clock signal, and a slave data driver connected to the master data driver in a cascade manner, wherein the slave data driver samples the second data information from the slave image signal.
Claims20
A display device comprising:
- a signal controller which outputs a master image signal having first data information and second data information;
- a master data driver which receives the master image signal and generates a slave image signal;
- and
- a slave data driver connected to the master data driver in a cascade manner,
- wherein the slave image signal corresponds to the second data information.
A data driving apparatus comprising:
- a sampling clock generator which generates a first sampling clock signal and a second sampling clock signal having substantially the same frequency as the first sampling clock signal using a master image signal which comprises first data information and second data information;
- a sampler which samples the first data information and the second data information using the first sampling clock signal;
- a slave clock generator which generates a slave clock signal using the second sampling clock signal;
- a slave image signal generator which generates a slave image signal which corresponds to the second data information using the slave clock signal;
- and
- a data voltage generator which generates a data voltage corresponding to the first data information.
