Patent ID: 8184114

Claim:
In a multi-panel display device configured of an alignment of multiple flat panel display devices for representing a single image, the multi-panel display device comprising multiple flat panel display devices, wherein each flat panel display device comprises: a display panel configured of a plurality of pixel regions; a data driver driving a plurality of data lines provided in the display panel; and a timing controller receiving image data and synchronization signals from an external source so as to divide the received image data, converting a signal frequency of at least one of the synchronization signals, and converting a size of the divided image data in accordance with the frequency-converted synchronization signal, thereby providing the size-converted divided image data to the data driver, wherein the timing controller comprises a data modulator dividing the video data enabling the divided video data to correspond to a structural position and size of a respective flat panel display device, and performing size expansion-conversion or size reduction-conversion on the divided video data with respect to the frequency-converted synchronization signal, thereby generating converted video data, a data alignment unit using at least one of the synchronization signals so as to align the converted video data with respect to the operation of the display panel, thereby providing the aligned converted video data to the data driver; and a control signal generator using at least one of the synchronization signals so as to generate a data control signal, and providing the generated data control signal to the respective data driver.
