Title:
FIELD-SEQUENTIAL DISPLAY DEVICE AND DRIVE METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/087597
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the scale of a circuit that generates display data and backlight data in each field. A field-sequential data generation unit (10) is characterized by including: a motion vector detection unit (11) that detects the motion vectors (MV) of input image data (D1); a backlight data generation unit (12) that generates backlight data (D2) on the basis of the input image data; an image data computation unit (13) that generates pre-interpolation display data (D3) on the basis of the backlight data and on the basis of image data (De) equivalent to the input image data; and an interpolation frame generation unit (14) that generates display data (D4) by performing frame interpolation including motion compensation using the motion vectors of the pre-interpolation display data. As a result of using such a configuration, backlight data is generated on the basis of input image data not subjected to frame interpolation, and circuit scale is reduced.
