Claim 0:
1. A multi-vision display device comprising:
a timing controller configured to receive source data and timing signals from a host, and generate a data packet comprising image data and control data;
a plurality of display panels; and
a plurality of display driver integrated circuits (ICs) cascade-connected to each other and each connected to any one of the plurality of display panels,
wherein each display driver IC comprises a driving unit configured to extract the image data corresponding to a panel identifier included in the control data and generate a data voltage driving a corresponding display panel,
wherein the data packet is a set of single control data and multiple image data arranged in a serial format,
wherein the image data included in the data packet is classified as PID0 to PIDn-1 according to the panel identifier when the multi-vision display device comprises n display driver ICs respectively connected to a corresponding display panel,
wherein the image data classified as PID0 to PIDn-1 is sequentially provided to first to nth display driver ICs cascade-connected to each other, where n is an integer greater than 2,
wherein each of the plurality of display driver ICs comprises:
a decoder configured to decode the data packet comprising image data and control data; and
a panel identifier modulator connected to the decoder and configured to:
modulate the panel identifier included in the control data and provided from the decoder, and
provide the modulated panel identifier to an encoder configured to generate an encoded data packet comprising image data and control data including the modulated panel identifier, and
wherein the encoded data packet is provided from a front end display driver IC to a rear end display driver IC, such that the image data classified according to the modulated panel identifier is displayed on a display panel corresponding to the rear end display driver IC.
