Abstract
An exemplary embodiment of the present invention provides a display device including red pixels, blue pixels, green pixels, and white pixels, a plurality of gate lines, and a plurality of data lines, wherein the red pixels, the blue pixels, and the green pixels are disposed to longitudinally extend in a vertical direction, and the white pixels are disposed to longitudinally extend in a horizontal direction below or above the red pixels, the blue pixels, and the green pixels.
Claims16
A display device, comprising:
- red pixels, blue pixels, green pixels, white pixels, a plurality of gate lines, and a plurality of data lines,
- wherein the red pixels, the blue pixels, and the green pixels are respectively disposed to longitudinally extend in a vertical direction, and the white pixels are disposed to longitudinally extend in a horizontal direction below or above the red pixels, the blue pixels, and the green pixels, wherein one row of the white pixels is disposed for every two RGB pixel rows in which the red pixels, the blue pixels, and the green pixels are arranged, wherein there is two rows of RGB pixels interposed between every two neighboring rows of white pixels, wherein the row of the white pixels is disposed between the RGB pixel rows, wherein a same image signal voltage from one of the data lines is applied to all the white pixels disposed in one row of the white pixels.
A display device, comprising:
- red pixels, blue pixels, green pixels, white pixels, a plurality of gate lines, and a plurality of data lines,
- wherein the red pixels, the blue pixels, and the green pixels are respectively disposed to longitudinally extend in a vertical direction, and the white pixels are disposed to longitudinally extend in a horizontal direction below or above the red pixels, the blue pixels, and the green pixels, wherein one row of the white pixels is disposed for every two RGB pixel rows in which the red pixels, the blue pixels, and the green pixels are arranged, wherein there is two rows of RGB pixels interposed between every two neighboring rows of white pixels, wherein a same voltage is applied to all the white pixels disposed in one row of the white pixels, wherein the row of the white pixels is operated like one pixel.
A display device having a liquid crystal panel assembly, comprising:
- a plurality of gate lines;
- a plurality of data lines;
- and
- a plurality of rows of pixels, comprising:
- a first row of pixels consisting of a plurality of red pixels, a plurality of blue pixels, and a plurality of green pixels;
- a second row of pixels immediately adjacent to the first row of pixels and in direct contact with the first row of pixels consisting of a plurality of red pixels, a plurality of blue pixels, and a plurality of green pixels;
- and
- a third row of pixels immediately adjacent to the second row of pixels and in direct contact with the second row of pixels consisting of a plurality of white pixels,
- wherein a pattern of the first, second and third row of pixels repeats until the liquid crystal panel assembly is filled,
- wherein the first and second rows of pixels receive a gate control signal solely through a first gate line of the plurality of gate lines, the third row of pixels receives another gate control signal solely through a second gate line of the plurality of gate lines, the first gate line receives the gate control signal solely from a gate driving IC mounted in the display device, and the second gate line receives the gate control signal from a gate driving circuit integrated in the display device, said first and second gate lines are separate lines, and said plurality of data lines are connected to the first, second, and third row of pixels.
