Abstract
A display device including: a display panel including a plurality of pixels; and a data driver configured to arrange the display panel into a plurality of pixel blocks, and to output a data voltage with different slew rates to the plurality of pixel blocks, wherein the slew rates are based on distances of the plurality of pixel blocks from the data driver, wherein a boundary between adjacent pixel blocks with different slew rates is changeable.
Claims20
A display device, comprising:
- a display panel including a plurality of pixels;
- and
- a data driver configured to arrange the display panel into a plurality of pixel blocks, and to output a data voltage with different slew rates to the plurality of pixel blocks, wherein the slew rates are based on distances of the plurality of pixel blocks from the data driver,
- wherein a boundary between adjacent pixel blocks with different slew rates is changeable.
1 more element
A display device, comprising:
- a display panel including a plurality of pixels;
- and
- a data driver configured to divide the display panel into a first pixel block and a second pixel block, wherein the first pixel block is closer to the data driver than the second pixel block, to output a data voltage with a first slew rate to the first pixel block, and to output the data voltage with a second slew rate higher than the first slew rate to the second pixel block,
- wherein a boundary between the first pixel block and the second pixel block is randomly set.
1 more element
A display device, comprising:
- a display panel including a plurality of pixels;
- a first data driver configured to output a data voltage to a first portion of the display panel;
- and
- a second data driver configured to output the data voltage to a second portion of the display panel,
- wherein the first data driver divides the first portion of the display panel into a plurality of first pixel blocks, and outputs the data voltage with different slew rates to the plurality of first pixel blocks according to their distances from the first data driver,
- wherein the second data driver divides the second portion of the display panel into a plurality of second pixel blocks, and outputs the data voltage with different slew rates to the plurality of second pixel blocks according to their distances from the second data driver, and
- wherein a boundary between the plurality of first pixel blocks and a boundary between the plurality of second pixel blocks are set independently of each other, and are changeable.
