3-dimensional image display apparatus and control method of the same

摘要

Provided are a 3-dimensional image display apparatus and a control method thereof, the apparatus including: a video signal receiving unit which receives a video signal containing plane image data or stereoscopic image data from an external signal source; a liquid crystal module which includes a liquid crystal display panel to selectively display the plane image data and the stereoscopic image data, and a backlight unit provided in a rear portion of the liquid crystal display panel; a power supply which supplies power to the liquid crystal module; and a controller which determines whether the received video signal contains the plane image data or the stereoscopic image data, and if the video signal receiving unit contains the stereoscopic image data, the controller controls the power supply such that the backlight unit operates in a power saving mode while the stereoscopic image data is scanned to the liquid crystal display panel.

1. A method of driving a display apparatus, the method comprising:
receiving a video signal from an external signal source; determining whether the received video signal is to be displayed in a 3-dimensional mode or a 2-dimensional mode; and controlling a power supply to supply electrical power to a light source in a first power mode in response to determining the received video signal is to be displayed in the 3-dimensional mode; and controlling a power supply to supply electrical power to the light source in a second power mode in response to determining the received video signal is to be displayed in the 2-dimensional mode, wherein an amount of electrical power consumed by the light source in the first power mode is different from an amount of electrical power consumed by the light source in the second power mode.
