A non-volatile memory device includes a cell region and a peripheral circuit region at the semiconductor substrate. A plurality active regions are disposed in the cell region in parallel with each other. A plurality of cell line patterns cross over the active regions in parallel. A couple of tunnel insulating layers and the floating gate electrodes are disposed between the cell line patterns and the active regions. A dummy region is interposed between the cell region and the peripheral circuit region where at least one dummy line pattern is disposed in the dummy region.

In a color adjustment method for a video display apparatus, the display apparatus is initialized and a mean luminance value L is calculated from a maximum luminance value and a minimum luminance value of the display apparatus when powered up. The hue and saturation data, which are received in accordance with a keypress, are transformed into RGB control data by hue and saturation conversions. The saturation data denotes a distance from a white point on an X-Y chromaticity coordinate system of the display apparatus to a chromaticness point on the chromaticity coordinate system, and the hue data denotes an angle made by a first line connecting a red point on the coordinate system and the white point with a second line connecting the white point and the chromaticness point. Finally, the gains and DC biases of the RGB video signals are controlled on the basis of the RGB control data. Thus, a user can easily and variously control the color of a video display apparatus by hue and saturation keys for color adjustment, without the help of one skilled in the art.

A computer monitor in which USB devices connected thereto can be operated with a host power supply voltage provided through host-connected hub ports, even though a power supply voltage from a power supply of the monitor has been cut off. The monitor detects when a power supply voltage to USB devices connected thereto is beyond a rated voltage, and shuts off an abnormal voltage of more than the rated voltage to the USB devices so as to prevent them from being damaged due to the abnormal voltage.

Display apparatus for computer system

0An apparatus and method for saving power by cutting off the power supplied to a monitor when an input signal does not exist for a given time period. An input signal is checked to see if it is sensed from input means of the monitor. A power circuit is operated each time the input signal is sensed and simultaneously a time value for performing a power saving mode is set in a reference buffer. The receiving time of the input signal is counted by updating the time value set in the reference buffer each time an interrupt signal is received from a timer, and then the time value of the reference buffer is read. If the input signal is not sensed until a setting time elapses, an operating voltage of the monitor is cut off by controlling the operation of the power circuit.
