Abstract:
A liquid crystal display device is provided with a liquid crystal display panel, and a data driver IC that drives the liquid crystal display panel. The liquid crystal display panel is provided with a gate line, first and second data lines, and a pixel that includes a first sub-pixel connected to the gate line and the first data line and a second sub-pixel connected to the gate line and the second data line. The data driver IC is provided with a gamma correction circuitry and a drive circuitry. The gamma correction circuitry generates first gamma-corrected data by performing gamma correction on externally received image data in accordance with a first gamma curve, and generates second gamma-corrected data by performing gamma correction on the image data in accordance with a second gamma curve. The drive circuitry drives the first data line in response to the first gamma-corrected data and drives the second data line in response to the second gamma-corrected data.
