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, the plurality of light emitting diodes comprising a first light emitting diode adjacent to the first side and a second light emitting diode adjacent to the second side; and
a driving circuit coupled to the plurality of light emitting diodes, and configured to generate a reference anode signal and a reference cathode signal;
wherein an anode of the first light emitting diode receives a first anode signal from the driving circuit, the first anode signal is different from the reference anode signal by a first signal difference, an anode of the second light emitting diode receives a second anode signal from the driving circuit, the second anode signal is different from the reference anode signal by a second signal difference, and the first signal difference is smaller than the second signal difference; and
wherein a cathode of the first light emitting diode receives a first cathode signal from the driving circuit, the first cathode signal is different from the reference cathode signal by a third signal difference, a cathode of the second light emitting diode receives a second cathode signal from the driving circuit, the second cathode signal is different from the reference cathode signal by a fourth signal difference, and the third signal difference is greater than the fourth signal difference.
