A display device is provided. The display device includes a data signal transmitter and a display panel. The data signal transmitter is used to transmit data signals. A display area of the display panel is divided into sub-display areas. Each sub-display area includes light emitting diodes, a data line, column switches, and row switches. A portion of the data line is formed as a data induction coil to receive one of the data signals by wireless sensing. The display panel selects one of the light emitting diodes as a selected light emitting diode by the column switches and the row switches. The selected light emitting diode is coupled to the data line to form a closed loop. The closed loop generates an induced current according to the data signal and causes the selected light emitting diode to emit light according to the induced current.
