Field sequential display device and drive method therefor

A field sequential type display device comprising:

• a display panel including a plurality of pixels arranged two-dimensionally;
• a backlight including a plurality of types of light sources having different emission colors, each of the types including a plurality of light sources;
• a field sequential data generation unit configured to generate display data used for driving the display panel and backlight data used for driving the backlight, based on image data for each frame including a plurality of pieces of color component data;
• a panel drive circuit configured to drive the display panel based on the display data in accordance with a color of a field in each field period;
• and
• a backlight drive circuit configured to control the light source of one or more types in accordance with the color of the field to be in a light emitting state, based on the backlight data in accordance with the color of the field in each field period,
• wherein the field sequential data generation unit includes
• a motion vector detection unit configured to detect a motion vector of the image data,
• a backlight data generation unit configured to generate backlight data that shows a brightness of the light source in each area for each field based on the image data, the area being obtained by dividing the backlight into a plurality of areas,
• an image data calculation unit configured to generate pre-interpolation display data that is display data before performing frame interpolation processing, based on the image data, or data equivalent to the image data, and the backlight data, and
• an interpolation frame generation unit configured to generate the display data by performing frame interpolation processing which includes motion compensation using the motion vectors, on the pre-interpolation display data.
