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.

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...
