Assignee: MAGNACHIP SEMICONDUCTOR, LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. A display driver IC comprising:
a receiver configured to receive a data packet comprising image data and control data;
a decoder configured to decode the received data packet;
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 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 a 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;
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 provided to a rear end display driver IC; and
a transmitter configured to output the encoded data packet to the rear end display driver IC, and
wherein the encoded data packet is provided from a front end display driver IC to the 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.
