Abstract: A signal processing circuit includes an input gamma adjuster configured to adjust gamma characteristics of an image signal and to output a gamma adjustment image signal, an image signal processor configured to generate a scaling signal corresponding to image characteristics of the gamma adjustment image signal and to convert the gamma adjustment image signal into an intermediate data signal in response to the scaling signal, and an output gamma adjuster configured to convert the intermediate data signal into a data signal on a basis of a first lookup table corresponding to a first gamma curve, a second lookup table corresponding to a second gamma curve, and the scaling signal.

Abstract: A liquid crystal display and a method for driving the same. The liquid crystal display includes: gate lines arranged in a row direction; data lines arranged in a column direction; and subpixels arranged in basic units of eight subpixels. Each subpixel is each connected to one of the gate lines and one of the data lines, and the subpixels are continuously arranged along a row and are arranged in a matrix. In the basic units, polarities between adjacent subpixels from a first subpixel to a fourth subpixel along the row are opposite to each other, polarities between adjacent subpixels from a fifth subpixel to an eighth subpixel along the row are opposite to each other, and polarities of the fourth subpixel and the fifth subpixel are the same.

Abstract: The present invention provides a display device including a first block including a first primary color pixel and a second primary color pixel having substantially a same area, a second block alternatingly disposed with the first block along the first direction, the second block including a third primary color pixel, a fourth primary color pixel and a white pixel. The first block and the second block have substantially a same area and the third primary color pixel has an area wider than the fourth primary color pixel and the white color pixel.
