Abstract: A display device includes a display panel including a first pixel column in which first and third color pixels are alternately disposed, a second pixel column in which second color pixels are disposed, a third pixel column in which the third and first color pixels are alternately disposed, and a fourth pixel column in which the second color pixels are disposed. The display device further includes a scan driver applying a scan signal to scan lines, a data driver including a first source channel supplying a first color data signal and a second color data signal to a first data line, and a second source channel supplying the second color data signal and a third color data signal to a second data line, and a demultiplexer successively selecting the first and second sub-data lines during a period in which the scan signal is supplied to each scan line.

Abstract: A display device includes: a data driver for supplying a data signal to each of a plurality of data lines; and a pixel unit including a plurality of sub-pixels. The pixel unit further includes one dummy data line disposed separate from a data line of a first column among the data lines. The data line of the first column is connected to sub-pixels disposed on odd-numbered pixel rows among sub-pixels disposed on a first pixel column, and is connected to sub-pixels disposed on even-numbered pixel rows among sub-pixels disposed on a third pixel column. The dummy data line is connected to sub-pixels disposed on the even-numbered pixel rows among the sub-pixels disposed on the first pixel column.

Abstract: A display device includes a pixel unit including first and second pixel columns arranged alternately along a first direction, and a third pixel column arranged between the first and the second pixel columns, a timing controller generating first or second image data by converting input image data, and a data driver generating a data voltage corresponding to the first or second image data and supplying the data voltage to the pixel unit. The first and second pixel columns each include first and second color pixels arranged alternately along a second direction, the third pixel column includes a third color pixel arranged along the second direction, and the timing controller compares a difference value between a grayscale value of the first color pixel and a grayscale value of the second color pixel with a reference value, and generates the second image data based on a comparing result.
