Abstract: Apparatus, method, and system for synchronization and a three-dimensional (3D) display apparatus using the same are provided. The 3D display apparatus includes: a power generator which generates power based on a received alternating current (AC) power signal, a detector which detects zero crossing points of time of the received AC power signal, and a controller which generates a reference signal based on the detected zero crossing points of time and transmits the reference signal to at least one other 3D display apparatus.

Abstract: An audio/video (AV) apparatus and a signal control method thereof are provided. The AV device includes: an AV interface which is configured to transmit and receive a first signal including AV data according to an High-Definition Multimedia Interface (HDMI) standard and to transmit and receive a second signal including an integrated data packet; a signal converter which selectively converts a received signal received through the AV interface; and a controller which determines whether the received signal is the first signal or the second signal, and controls the signal converter to bypass the received signal or convert the received signal into a converted signal according to the determination.

Abstract: A display apparatus having a backlight unit whose brightness is adjusted according to input image signals. The display apparatus processes input image signals in order for them to be appropriate to a display characteristic in an image signal processing unit and outputs each chromatic signal, R, G, and B, related to a color configuration of the image signals, processed in the chromatic signal output unit. Then a display panel drives an image display screen according to each chromatic signal. Meanwhile, a chromatic averaging unit calculates average brightness of the input images from each chromatic signal to transfer to a controller. The controller controls an inverter through an inverter current limiting unit in order for currents provided to the backlight unit in the display panel, to be controlled according to the average brightness of the input images calculated in the chromatic signal averaging unit.
