Patent ID: 7961205

Claim:
A display apparatus comprising: a display panel comprising a plurality of pixels, each of which comprises red, green and blue horizontal sub-pixels, each of the horizontal sub-pixels having a first side extending along a first direction and a second side extending along a second direction substantially perpendicular to the first direction, the second side being shorter than the first side; a data modifier configured to receive first, second and third image data for red, green and blue vertical sub-pixels each having a first side extending along the first direction and a second side extending along the second direction, the second side being longer than the first side, the data modifier configured to modify the first, second and third image data, and to output first, second and third modified image data for the red, green and blue horizontal sub-pixels; a timing controller configured to receive the first, second and third modified image data from the data modifier and to output a data control signal and a gate control signal in response to a control signal from an external device; a data driver configured to receive the first, second and third modified image data from the timing controller in synchronization with the data control signal, to convert the first, second and third modified image data into data voltages, and to apply the data voltages to the red, green and blue horizontal sub-pixels; and a gate driver configured to sequentially output a gate pulse in response to the gate control signal to turn on the red, green and blue horizontal sub-pixels, wherein the first, second and third image data are defined as data values corresponding to first, second and third positions at center regions of the red, green and blue vertical sub-pixels, respectively, the first, second and third modified image data are defined as data values corresponding to fourth, fifth and sixth positions at center regions of the red, green and blue horizontal sub-pixels, respectively, wherein the second and fifth positions are the same, and wherein the data modifier is further configured to: generate the first modified image data based on a first image data of a preselected pixel among the pixels and a first image data of at least three pixels adjacent to the preselected pixel; output a second image data of the preselected pixel as the second modified image data; and generate the third modified image data based on a third image data of the preselected pixel and a third image data of at least three pixels adjacent to the preselected pixel.
