SYSTEM AND DEVICE FOR DISPLAYING VIDEO ON DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To prevent deterioration in display image quality by reducing a disturbance in an image occurring in a dynamic image among display images on a display panel. SOLUTION: This device is provided with a data processing means 6 dispersing the disturbance in the image at a fixed distance or above as filed unit or as frame unit according to detection of a signal level causing the disturbance in the image of an input video signal and an output processing means 7 dividing to N sheets of sub-field(SF) pictures answering to display gradations of N bits (N is integer of 2 or above, 356 gradations when N=8), weighting the number of applied displaying pulses of respective SF pictures by the number of answering bits and displaying a halftone. Thus, the disturbance in the image integraged on the human retina is dispersed at the fixed distance or above as field unit or as frame unit, and the disturbance in the image is reduced.
