Title:
SELF-LUMINOUS DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2014126698
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a self-luminous display device capable of suppressing image persistence phenomenon on a screen by calculating a quantity of light emission from a video signal and controlling the video signal flexibly.SOLUTION: The self-luminous display device comprises: a data calculation unit that calculates data related to a quantity of light emission accumulated in a first block unit in a target region for brightness control in a screen where a plurality of pixels each having a light-emitting element self-luminous according to an amount of current are arranged in matrix; a resampling unit that resamples the data in the target region calculated by the data calculation unit in a second block unit larger than the first block; and a scaling unit that scales the data resampled by the resampling unit to the first block unit and generates brightness control data for the target region.
