ABSTRACT:
An apparatus for auto calibration of a display device, the apparatus including a signal generating unit for generating predetermined digital patterns, converting the digital patterns into R, G, B and Y, U, V color signals, converting the color signals into analog pattern signals, and outputting the analog pattern signals; a calibration performing unit for converting the analog pattern signals into digital pattern signals, adjusting the offset and gain of the digital pattern signals using control signals, and outputting the offset and gain of the digital pattern signals; and a control unit for operating the signal generating unit and the calibration performing unit once a calibration performing mode starts, comparing the digital pattern signals to reference values, and outputting the control signals for adjusting the offset and gain of the digital pattern signals such that the digital pattern signals are identical to the reference values.
