Abstract: An image display apparatus for correcting a motion compensation error and a method thereof are provided. The image display apparatus includes an image signal processing unit which detects a motion vector from an input image signal to determine a border region between a non-image display region and an image display region; and a controller which determines the kind of input images through a location information on the border region to control the image signal processing unit to compensate for and output a motion of the input image signal according to the kind of the input images.

Abstract: An apparatus for adjusting a sampling phase in analog to digital conversion, and an adjustment method thereof is disclosed. Provided are an apparatus for adjusting a sampling phase of a digital display including a phase locked loop (PLL) circuit unit for converting a frequency of a sampling clock signal and outputting the converted frequency, the sampling clock signal for converting an analog video signal into digital format, an analog to digital converter (ADC) for converting the incoming analog video signal into digital format using the sampling clock signal input from the PLL circuit unit, a detection unit for detecting a maximum phase shift of the video signal converted at the ADC, and a control unit for controlling the PLL circuit unit so that the sampling phase can be adjusted in accordance with the maximum phase shift detected by the detection unit, and an adjustment method of the apparatus.

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.
