Abstract: The present invention provides an apparatus for controlling a video output of an audio video navigation (AVN) system, including: a display unit which displays a video in the AVN system; a signal dividing unit which divides an input first signal, transmits the video to the display unit using a second signal obtained by dividing the first signal and senses a user input on the display unit using a third signal obtained by dividing the first signal; and a video output control unit which controls an output of a video which conforms with a predetermined standard, using the first signal and controls an output of a video corresponding to the user input.

Abstract: A liquid crystal display (LCD) device with a register-type gamma reference voltage generating unit inside a data driving IC, thus to remove a source block dim phenomenon in a Chip on Glass (COG) cascade structure, and a driving method thereof. The LCD device comprises an LCD panel on which a plurality of gate lines and data lines intersect with each other. A TFT is formed at each intersection, to thus define images. A data driving unit supplies a gradation voltage to the LCD panel through a gamma voltage generating unit. A gate driving unit supplies a gate pulse to each gate line on the LCD panel. A timing controller controls the gate driving unit, the data driving unit and the gamma voltage generating unit.

Abstract: A method of driving a lamp includes receiving a source power output from a power source; generating a first control signal; adjusting at least one attribute of the received source power based on the first control signal to generate a first lamp-driving power, the first lamp-driving power inducing a first tube current having a first tube current value within the lamp; after generating the first control signal, generating a second control signal, different from the first control signal; and adjusting at least one attribute of the received source power based on the second control signal to generate a second lamp-driving power, the second lamp-driving power inducing a second tube current having a second tube current value within the lamp, wherein the second tube current value is different from the first tube current value.
