The present invention provides an LCD capable of being driven with various frequencies without deterioration of image quality. According to the present invention, a method of driving an LCD in two-dot inversion for a low vertical frequency and in one-dot inversion for a high vertical frequency is provided. The method determines whether the vertical frequency of the LCD changes, changes the inversion type into one-dot inversion if the vertical frequency is changed from a low frequency to a high frequency, and changes the inversion type into two-dot inversion if the vertical frequency is changed from a high frequency to a low frequency. Moreover, if a flicker is generated when driving in one-dot inversion, the inversion type is changed into two-dot inversion. To avoid the unequal charging generated in the LCD driven in two-dot inversion, the pulse width of the gate signals are adjusted after measuring the load of the data line.

A head drum assembly comprises a stationary drum, a rotary drum, and a self-compensating dynamic balancer. The stationary drum is fixed to a shaft, and the rotary drum is rotatably mounted to the shaft so that it faces the stationary drum. The rotary drum supports a magnetic head. The self-compensating dynamic balancer automatically compensates for any eccentricity between the rotational axis and the centroid of the rotary drum by using the centrifugal force of the rotary drum being rotated.

A liquid crystal display includes a liquid crystal display panel for displaying picture images, and a color correction unit. Upon receipt of raw RGB picture data corresponding to raw RGB gamma curves, the color correction unit generates corrected RGB picture data based on values over a predetermined imaginative gamma curve established in accordance with the characteristic of the liquid crystal display panel. The color correction unit stores values over corrected RGB gamma curves corresponding to the corrected picture data, and gamma-corrects the raw RGB picture data based on values over the stored corrected RGB gamma curves, thereby displaying the picture images.
