Patent ID: 8810479

Claim:
In a multi-panel display device configured to align multiple flat panel display devices for representing a single image, the multi-panel display device comprises: at least one image display unit configured to align the multiple flat panel display devices aligned in an n×m formation (wherein m and n are integers being equal to or different from one another, and wherein m≧1, n≧1); at least one data converter being configured to correspond to each image display unit, dividing externally inputted video data in accordance with offset information inputted and stored by a user, and converting the size of the divided video data, thereby providing the converted divided video data to each flat panel display device, wherein the offset information includes structural position information of each display device, a total size information of the multi-panel display device, size information of each individual display device, and alignment position information of the display devices, wherein each data converter comprises an ID set-up unit internally setting up an ID signal based upon the offset information inputted by the user, thereby storing and outputting the set-up ID signal; a frequency converter performing expansion-conversion or reduction-conversion on a signal frequency of at least one synchronization signal inputted from an external source, thereby generating a frequency-converted synchronization signal; an image extractor detecting and dividing the video data with respect to the ID signal, thereby generating and outputting a plurality of divided video data; and a plurality of image converters expanding or reducing the size of the divided video data using the frequency-converted synchronization signal, thereby providing the size-converted divided video data to each of the flat panel display devices, wherein in the plurality of image converters each of the video data portions is read and outputted, based upon the converted synchronization signals, so as to perform expansion-conversion or reduction-conversion in both horizontal and vertical directions on the read video data portions, thereby generating converted video data portions, wherein the ID set-up unit sets up a unique ID signal based upon at least one of the offset information including structural position information of each display device, the size information of the inputted video data, the total size information of the multi-panel display device, the size information of each individual display device, and the alignment position information of the display devices, thereby storing and outputting the set-up ID signal, and wherein the image extractor detects the video data, which are inputted from an external source, for each region in accordance with the offset information including the structural position information of each display device, the total size information of the multi-panel display device, the size information of each individual display device, and the alignment position information of the display devices, thereby generating divided video data portions.
