Abstract: A display device includes a first luminescent device, a second luminescent device, a multi-color strobe decoder, a pseudo signal circuit and a single-color driving circuit. The multi-color strobe decoder is configured to generate two gate control signals. The second luminescent device and the pseudo signal circuit are coupled to the multi-color strobe decoder. The single-color driving circuit is coupled to the first luminescent device and the multi-color strobe decoder. When the single-color driving circuit provides first current for driving the first luminescent device according to the first gate control signal and/or a brightness enhancing signal, the pseudo signal circuit is configured to couple a first bias voltage to the multi-color strobe decoder according to the first gate control signal. When the second gate control signal drives the second luminescent device, the second luminescent device is configure to couple a second bias voltage to the multi-color strobe decoder.
