Abstract: The present invention relates to a video display apparatus and an operating method therefor. The operating method for a video display apparatus according to one embodiment of the present invention comprises: receiving video information on an incoming video from outside or on a broadcast video; detecting conversion information between a 2D video and a 3D video within 3D video information, when the received video information is 3D video information; performing a 2D signal processing or a 3D signal processing on either the incoming video from outside or the broadcast video, according to the conversion information. In this way, it becomes easier to find out whether an incoming video from an external device is a 2D video or a 3D video.

Abstract: An image display apparatus and a method for operating the same are disclosed. The method of operating an image display apparatus includes receiving an input external image, receiving supplementary information indicating the number of external images to be displayed or the number of sub images in the external image to be displayed, rearranging the external image or sub images based on the supplementary information, and displaying the rearranged external images or sub images. Accordingly, it is possible to conveniently detect the number of external images to be displayed or the number of sub images to be displayed.

Abstract: The present invention relates to a video display device and an operating method therefore. An operating method for a video display device according to one embodiment of the present invention comprises the steps of: determining whether or not a text is contained in an input video; determining whether or not a text display mode is a 2D text display mode when a text is contained in the video; separating a text region in the video when the text display mode is a 2D text display mode; performing 3D signal processing on the video region separated from the text region; performing 2D signal processing on the text region; and displaying the 2D signal-processed text region and the 3D signal-processed video region on a display. Accordingly, text can be displayed clearly when a 3D video is displayed.

Abstract: The present invention relates to an image-processing method for a display device which outputs three-dimensional content, and to a display device adopting the method. More particularly, the present invention relates to an image-processing method for a display device and to a display device adopting the method, in which the display device for outputting three-dimensional content processes both left image data and right image data of three-dimensional image data into images, and outputs the images in a three-dimensional format.

Abstract: An electromagnetic interference (EMI) prevention apparatus for a flat panel display which is capable of modulating the frequency of an input clock signal using a spread spectrum clocking method to increase the frequency of the clock signal and reduce the amplitude thereof so as to reduce EMI by a clock signal generated from a format converter of the flat panel display. The amount of electromagnetic energy radiated from a signal source of the flat panel display can be reduced to eradicate the root of an EMI problem, thus excluding the use of a conventional shielding plate device.
