Claim 0:
1. A display device, comprising:
a glass substrate, comprising a first side and a second side, the first side and the second side being two opposite sides of the glass substrate;
a plurality of light emitting diodes, arranged on the glass substrate and as a row extending from the first side to the second side, each of the plurality of light emitting diodes receiving a first anode signal, a second anode signal, a first cathode signal, and a second cathode signal; and
at least one driving circuit coupled to the plurality of light emitting diodes, and configured to generate a first reference anode signal, a first reference cathode signal, a second reference anode signal and a second reference cathode signal,
wherein an anode of each of the plurality of light emitting diodes receives the first anode signal different from the first reference anode signal by a first signal difference and the second anode signal different from the second reference anode signal by a second signal difference,
a cathode of each of the plurality of light emitting diodes receives the first cathode signal different from the first reference cathode signal by a third signal difference and the second cathode signal different from the second reference cathode signal by a fourth signal difference, and
the plurality of light emitting diodes that are closer to the second side have the greater first signal difference and the greater third signal difference, and the plurality of light emitting diodes that are closer to the first side have the greater second signal difference and the greater fourth signal difference.
