Abstract:
A display device employing a field-sequential method, comprising:a light source having a plurality of colors of emitted light; a light emission switching unit for sequentially switching the plurality of colors of emitted light of said light source within one frame; a light switching element for controlling an intensity of light from said light source for display; a control unit for controlling synchronization of a light-emission timing of each color of emitted light of said light source and a switching of said light switching element; and a frame number changing unit for changing a frame number per unit time; wherein said control unit controls the synchronization of the light emission timing and the switching in accordance with the frame number changed by said frame number changing unit, wherein said frame number changing unit comprises a discrimination circuit for judging whether display data is motion picture data or still picture data, and a changing circuit for changing the frame number per unit time based on a result of the judgement by said discrimination circuit.
