Abstract

A display apparatus, includes: a display panel including: gate lines extended in a first direction, data lines extended in a second direction, sub-pixels, and a first color filter, a second color filter, and a substantially colorless portion sequentially arranged in the first direction in one-to-one correspondence with the sub-pixels; and a light providing unit configured to supply a first color of light and a second color of light different from the first color of light to the display panel in association with a first sub-frame and a second sub-frame, respectively. At least some of the sub-pixels are grouped into a sub-pixel group including an “a”דb” matrix arrangement, the sub-pixel group being connected to an amount “a” of the gate lines and an amount “b” of the data lines, and “a” and “b” are positive integers greater than zero and “b” is greater than “a.”

a light providing unit configured to supply a first color of light and a second color of light different from the first color of light to the display panel in association with a first sub-frame and a second sub-frame, respectively,
wherein at least some of the sub-pixels are grouped into a sub-pixel group comprising an “a”דb” matrix arrangement, the sub-pixel group being connected to an amount “a” of the gate lines and an amount “b” of the data lines,
wherein “a” and “b” are positive integers greater than one, and
wherein “b” is greater than “a,”
wherein, in association with the sub-pixel group:
a first data line and a second data line are directly disposed between a first sub-pixel corresponding to the first color filter and a second sub-pixel corresponding to the second color filter, the first sub-pixel being directly spaced from the second sub-pixel in the first direction; and
a third data line and a fourth data line are directly disposed between the second sub-pixel and a third sub-pixel corresponding to the colorless portion, the second sub-pixel being directly spaced from the third sub-pixel in the first direction, and
