An output device for controlling an operation of a double-sided display panel, according to an embodiment of the present invention, comprises: a master controller for controlling an operation of a front display panel; a slave controller for controlling an operation of a back display panel; a first MUX which is controlled by the master controller and receives a first image inputted to the master controller and a second image inputted to the slave controller; and a second MUX which is controlled by the slave controller and receives the first image and the second image, wherein the master controller may control the first MUX and the second MUX to output either of the first image or the second image to each of the front display panel and the back display panel, on the basis of an image output control command.

Output device for controlling operation of double-sided display

The present invention relates to a multi-vision having a daisy chain type, capable of automatically setting an ID of each multi-vision set in a multi-vision where a plurality of sets are connected to each other in a daisy chain form, and an ID allocating method thereof. The multi-vision having a daisy chain type includes: a plurality of multi-vision sets; a first off switch provided at an IR communication line output port of each of the multi-vision sets, and configured to block an IR signal applied to each multi-vision set; series communication lines connected to the plurality of multi-vision sets in a bypass form; a second off switch provided at an output port of the series communication line of each multi-vision set, and configured to block an ID value which is to be bypassed to a next multi-vision set through the series communication line; and a controller configured to set an ID of a reference multi-vision set by blocking the first and second off switches, and configured to transmit an ID increased value to a next multi-vision set by releasing the blocked output state of the second off switch from the reference multi-vision set.

Multi-vision having daisy chain type and ID allocating method thereof

A device configuring a multi-display system is disclosed. The device configuring the multi-display system includes a first interface unit providing an access path for access to another device, a second interface unit connected to the first interface unit through a first bus and a second bus, a processor transmitting a first command and receiving a second command, a TX line connecting the processor to 'one of the first bus and the second bus' to transfer the first command, an RX line connecting the processor to 'one of the first bus and the second bus' to transfer the second command, and a switch unit connecting the RX line and one of the first bus and the second bus, or connecting the TX line and one of the first bus and the second bus, wherein the processor controls the switch unit to respectively connect the RX line to the first bus and the TX line to the second bus or to respectively connect the RX line to the second bus and the TX line to the first bus.

Display device and command transmission method thereof

A multi-vision device can include a first display set configured to display a first split image of an entire image of content according to a progressive scanning method; a second display set disposed on a lower side of the first display set to display a second split image of the entire image; and a control unit configured to scan the second split image on the second display set according to a reverse-progressive scanning method, invert the scanned second split image vertically and display the inverted second split image on the second display set.
