Electronic device including LED transmission device, and control method therefor

A method of arranging light emitting diodes (LEDs), the method comprising:

• dividing a transfer substrate arranged with a plurality of LEDs into a plurality of areas;
• determining a target pitch and a target arrangement position for transferring the each of the plurality of LEDs to a target substrate;
• determining a value of an output feature of the target substrate corresponding to an area from among the plurality of areas included in the target substrate based on the target pitch, the target arrangement position, and feature information about the plurality of LEDs;
• and
• based on the value of the output feature being within a predetermined range, arranging the plurality of LEDs on the target substrate based on the target pitch and the target arrangement position,
• wherein after the arranging, a plurality of output features of the plurality of areas included in the target substrate are uniform, and LEDs from different areas from among the plurality of areas of the transfer substrate are arranged in one area of the target substrate.
