Abstract

Provided is a self-luminous display device including a data calculation section configured to calculate, by using a supplied video signal, data relating to a luminance amount accumulated in a unit of a first block in a target region for luminance control in a screen on which a plurality of pixels are arranged in a matrix, each of the pixels including a light emitting element which emits light by itself according to a current amount, a resampling section configured to resample the data relating to the luminance amount in the target region, in a unit of a second block, the data relating to the luminance amount being calculated by the data calculation section, the second block being larger than the first block, and a scaling section configured to generate data for luminance control in the target region by scaling the data resampled by the resampling section. According to the invention, the luminance can be calculated according to the video signal, and the image persistence phenomenon of the screen can be inhibited flexibly by controlling the video signals.

Description

technical field [0001] The present invention relates to a self-luminous display device, a control method and a computer program for the self-luminous display device. Background technique [0002] As flat-panel thin display devices, liquid crystal display devices using liquid crystals and plasma display devices using plasma have been put into practical use. [0003] A liquid crystal display device is a display device provided with a backlight, which displays an image by changing the arrangement of liquid crystal molecules by applying a voltage and by transmitting and shielding light from the backlight. In addition, a plasma display device is a display device that has a plasma state by applying a voltage to a gas enclosed in a substrate, and passes ultraviolet rays (ultraviolet rays are generated by energy generated when returning from a plasma state to an initial state) Images are displayed by irradiating phosphors to convert ultraviolet rays into visible light. [0004] On...
