Abstract: The present invention discloses a display device capable of performing black frame insertion. The gamma circuit comprises an either-or multiplex selector. The input data of one input end of the selector is a VCOM voltage outputted by the gamma circuit, and the input data of the other input end of the selector is a voltage converted from a predetermined value after digital to analog conversion stored in a multi time programmable memory of the gamma circuit. As the selector selects the VCOM voltage outputted by the gamma circuit under control of the control port, the outputted VCOM voltage is amplified by an operational amplifier in the gamma circuit and then outputted to the source driving circuit to be a first gamma reference voltage which is required as the source driving circuit performs digital to analog conversion.
