Abstract
A driver for a display device includes: a timing controller for generating first and second signals; and a plurality of data drivers provided with a plurality of data drivers disposed on the left of the timing controller, a data driver disposed at the center thereof, and a plurality of data drivers disposed on the right thereof, wherein the plurality of data drivers disposed on the left are driven in response to the first signal, and the plurality of data drivers disposed on the right are driven in response to the second signal.
Claims22
A driver for a display device, the driver comprising:
- a timing controller for generating a first signal and a second signal;
- and
- a plurality of data drivers connected to receive signals from the timing controller for a left section, a data driver connected to receive signals from the timing controller for a center section of the display device, and a plurality of data drivers connected to receive signals from the timing controller for a right section,
- wherein the plurality of data drivers for the left section are driven in response to the first signal, and the plurality of data drivers for the right section are driven in response to the second signal.
A driver for a display device, the driver comprising:
- a timing controller for generating a first signal and a second signal;
- a first group of a plurality of data drivers for a first section of the display device, the data drivers connected to receive a signal from the timing controller, the first group of data drivers defining a group one data drivers arranged from a first data driver to an Nth data driver;
- an individual data driver divided into a first driving region that is driven in response to the second signal, and a second driving region that is driven in response to a carry signal generated from a previous-stage data driver;
- and
- a second group of a plurality of data drivers for a second section of the display device, the data drivers connected to receive a signal from the timing controller, the second group of data drivers defining a group two data drivers arranged from a first data driver to an Nth data driver;
- wherein the group one data drivers are driven in response to the first signal, and the group two data drivers are driven in response to the second signal.
A method of driving a display device comprising a timing controller for generating a first signal and a second signal, a first group of a plurality of data drivers for a first section of the display device, the data drivers connected to receive a signal from the timing controller, the first group of data drivers defining a group one data drivers arranged from a first data driver to an Nth data driver, an individual data driver divided into a first driving region that is driven in response to the second signal and a second driving region that is driven in response to a carry signal generated from a previous-stage data driver, and a second group of a plurality of data drivers for a second section of the display device, the data drivers connected to receive a signal from the timing controller, the second group of data drivers defining a group two data drivers arranged from a first data driver to an Nth data driver, the method comprising the steps of:
- supplying the first signal to a first group one data driver, and
- supplying the second signal to the first driving region of the individual data driver.
A method of driving a display device comprising:
- generating a first timing controller signal and a second timing controller signal;
- grouping a plurality of data drivers for a first section of the display device into a first group, the data drivers connected to receive a timing controller signal, the first group of data drivers defining a group one data drivers arranged from a first data driver to an Nth data driver;
- dividing an individual data driver into a first driving region that is driven in response to the second signal and a second driving region that is driven in response to a carry signal generated from a previous-stage data driver;
- grouping a plurality of data drivers for a second section of the display device into a second group, the data drivers connected to receive a timing controller signal, the second group of data drivers defining a group two data drivers arranged from a first data driver to an Nth data driver;
- driving a first group one data driver with the first signal;
- driving the first driving region of the individual data driver with the second signal;
- driving a second group one data driver with a group one carry signal after the first group one data driver completes processing the first signal;
- driving a first group two data driver with a group two carry signal after the first driving region of the individual data driver completes processing the second signal;
- driving sequentially each remaining group one data drivers with a carry signal generated by an immediately preceding group one data driver when the immediately preceding group one data driver completes processing its carry signal, the Nth group one data driver generating a carry signal that drives the second driving region of the individual data driver;
- driving sequentially each remaining group two data drivers with a carry signal generated by an immediately preceding group two data driver when the immediately preceding group two data driver completes processing its carry signal,
- wherein the second driving region of the individual data driver and the Nth group two data driver complete processing their carry signals at substantially the same time.
