Abstract: A voltage generator that prevents latch-up includes: a charge pump circuit that is controlled by first through third enable signals, boosts an internal power voltage generated from an external power voltage, and generates first through fourth voltages; a detector that detects the first through third voltages and generates first through third flag signals that go logic high when the first through third voltages reach predetermined respective voltage levels and maintain logic low when the voltages do not reach the predetermined respective voltage levels; and a charge pump controller that receives the first through third flag signals, and generates the first through third enable signals to have the first through fourth voltages sequentially generated. The voltage generator can prevent latch-up that may occur in a boosting mode or in a normal operation mode.

Abstract: A charge pump circuit and related method are provided. The charge pump circuit includes first, second and third voltage generation units, first and second control units, and a latch-up prevention unit. The first generation unit regulates a first output signal, the second generation unit boosts a second output signal, and the third generation unit boosts a third output signal in response to the first and second output signals. The first control unit is connected between the first generation unit and the third generation unit, and the second control unit is connected between the second generation unit and the third generation unit. The first and second control units block respective outputs of the first and second generation units during the boosting time for the second output signal. The latch-up prevention unit prevents a latch-up operation caused by a parasitic transistor until the third output signal is maintained at a third voltage.

Abstract: A partial region on a screen can be selected for highlighting. Information related to the partial region is transmitted from a computer to a computer monitor. In one embodiment, the partial region information is sent over a different port from the one used to send video data. The image processor adjusts contrast and sharpness of the partial region according to the partial region information. Adjustments are made for differences in a coordinate system between the computer site and the display device. The partial region can be selected from the computer or from a user interface on the computer monitor. Selected partial regions can be moved in conjunction with movements of windows containing the image. Highlighted selected regions can also be automatically disabled when the window is deactivated.
