Abstract
The disclosure discloses a backboard, a display device, and a method for fabricating the same, and the backboard includes: a backboard body; and a plurality of LED installation mounts arranged in an array on the backboard body, wherein each of the plurality of LED installation mounts includes at least two lead-out electrodes to be connected with LED pins, and a coil structure around each of the at least two lead-out electrodes, wherein the coil structure is configured to produce a magnetic field upon being powered on. The coils can be formed on the backboard body in the backboard to absorb electrodes of LEDs to thereby position them precisely so as to transfer the LEDs in a mass manner with a high good yield ratio, and the lead-out electrodes can be powered on to thereby detect abnormally operating LEDs.
