Electronic device and controlling method of electronic device

A method of controlling an electronic device, the method comprising:

• transmitting, by at least one processor of the electronic device through a plurality of timing controllers of the electronic device, a first signal comprising image data and a control instruction for transmitting the image data in a first direction, wherein each of the plurality of timing controllers comprises two ports disposed in opposite directions, and wherein the plurality of timing controllers are connected to each other through the respective two ports;
• identifying, by the plurality of timing controllers, an input/output direction of each of the two ports of each of the plurality of timing controllers corresponding to the first direction;
• configuring the two ports of each timing controller of the plurality of timing controllers to correspond to the identified input/output directions;
• transmitting, by the plurality of timing controllers, the first signal in the first direction through the two ports of each timing controller of the plurality of timing controllers;
• and
• transmitting a state signal corresponding to a state of a display panel of the electronic device based on whether at least one of the plurality of timing controllers receives the first signal within a predetermined threshold time, wherein the state signal is transmitted from at least one of the plurality of timing controllers to the at least one processor.

A non-transitory computer readable medium having instructions stored therein, which when executed by at least one processor cause the at least one processor to execute a method of controlling an electronic device, the method comprising:

• transmitting, by the at least one processor through a plurality of timing controllers of the electronic device, a first signal comprising image data and a control instruction for transmitting the image data in a first direction, wherein each of the plurality of timing controllers comprises two ports disposed in opposite directions, and wherein the plurality of timing controllers are connected to each other through the respective two ports;
• identifying, by the plurality of timing controllers, an input/output direction of each of the two ports of each of the plurality of timing controllers corresponding to the first direction;
• configuring the two ports of each timing controller of the plurality of timing controllers to correspond to the identified input/output directions;
• transmitting, by the plurality of timing controllers, the first signal in the first direction through the two ports of each timing controller of the plurality of timing controllers;
• and
• transmitting a state signal corresponding to a state of a display panel of the electronic device based on whether at least one of the plurality of timing controllers receives the first signal within a predetermined threshold time, wherein the state signal is transmitted from at least one of the plurality of timing controllers to the at least one processor.
