Requirements for Intelligible Audio Description
Aiming for audio description that is easy to follow
Research is being done on the automatic provision of audio description for program video. This exhibit features the subjective evaluation of the positive aspects of the audio description automatically generated from the game-related data of the Rio de Janeiro Olympics and Paralympic games.


Advanced Technology Behind 8K Shooting
Autofocus technologies and electronic variable neutral-density fi lters
Research is being done on technologies relating to shooting in 4K and 8K. This exhibit features high-precision autofocus technologies for 4K and 8K, and electronic neutral-density fi lters for cameras that can continuously control incident light over a wide range.


Audio Coding for Next Generation Terrestrial Broadcasting Systems
High-effi ciency coding and multifunctionalization by MPEG-H 3D audio
Audio coding scheme equipped with high-effi ciency and multifunction based on MPEG-H 3D Audio is being prepared, toward next generation terrestrial broadcasting. This exhibit features high-effi ciency coding technology that can compress 22.2ch audio signal to 1/50 of its original size, as well as multifuctionalization of audio services available in objectbased audio.


Movie Contents Preferred to Be Viewed in a Wide Visual Field
Producing effective images for 8K wide-fi eld viewing environments
In order to produce 8K video, research is being done on the characteristics of the images preferred for wide-field viewing. We performed an experiment to evaluate preferred physical size of various scenes in 8K and to investigate the effect of viewing distance on the preferred size.


Spatial Light Modulator with Narrow Pixel Pitches
Technology for the future holographic 3D displays
Research is being done on ultra high density display devices which are essential for realizing 3D electro-holography. This exhibit features a 2μm pixel-pitch spatial light modulator with a larger 1,000 x 1,000 pixel layout (100 times larger than that of last year), as well as new structural elements for lower driving currents.


Optical Phased Array
To realize an integral 3D display without lens array
For a future integral 3D display that does not require lens array, we are developing an optical phase array capable of controlling the direction and shape of light beams. This exhibition explains the principle of the beam steering in polymer-based optical phased array and experiments on beam defl ection of the fabricated devices.


Eco-Friendly Quantum Dot Light-Emitting Diodes
For wide-color gamut displays
Research is being done on light-emitting diodes using solution-processable quantum dots that offer luminescence with high color purity. We have come up with our own prototype eco-friendly, quantum dot light-emitting diodes that do not use toxic cadmium element.


High-Performance Thin-Film Transistors for Sheet-Type Displays
High-current operation utilizing the resistance-reduction phenomenon in oxide semiconductors
Research is being done on high-performance oxide thin-fi lm transistors in order to achieve high-resolution, low-power sheet-type displays. This exhibit features a technology for highcurrent operation of oxide TFTs utilizing the resistance-reduction phenomenon in oxide semiconductors.


Solid-State Image Sensor Overlaid with Photoelectric Conversion Layer
For more sensitive 8K Super Hi-Vision cameras
Research is being done on solid-state imaging sensors overlaid with a charge multiplication photoelectric conversion fi lm in order to achieve highly sensitive 8K cameras. This exhibit features efforts and improvements for reduction both in film dark current and in noise of CMOS circuits overlaid with the fi lm.


Elemental Technologies for High-Resolution Organic Image Sensors
Aiming for small, high-resolution single-chip color cameras
Research is being done on organic image sensors with three organic films that provide sensitivity for each of the primary colors. This exhibit features a cell-shaping technology for sandwiching organic fi lms between transparent electrodes and improving the cell properties.
