∽∽────────────────────────∽∽ Part 1 Trends in optically functional materials, the importance of anti-reflection coatings and future prospects ∽∽────────────────────────∽∽ [Purpose of the lecture] After understanding the basics of technology regarding optically functional materials and films, we will explain the technological trends and application development of anti-reflection films in particular, and look ahead to the future. [Program] 1.Trends in optically functional materials 1.1 Photonics polymers that make up optical films 1.1.1 Optical functions and classification of photonic polymers (In addition to PMMA, PC, PET, TAC, etc., we will introduce new materials such as transparent PI and fully fluorine resin) 1.1.2 Utilization of fluorine-based photonics polymer (Anti-reflective finishing agent, fingerprint remover, inkjet bank material, metal wiring forming material, etc.) 1.2 Basics and market of display optical films 1.2.1 Changes in displays and optical films 1.2.2 Types, functions, and market trends of display optical films 1.2.3 Principles and
characteristics of display optical films (individual introduction) Nanorin plint (wire grid, etc.), brightness improved film,

Importance of anti-reflection coating and future prospects 2.1 Anti-reflection in automotive displays 2.2 Anti-reflection in organic EL displays (Circular polarizing film method, color filter method) 2.3 Future trends of anti-reflection coatings (New film material, moth eye reflection prevention, etc.) [Q&A] ∽∽────────────────────────∽∽ Part 2 Fabrication and mass production technology of anti-reflection processed film by nanoimprinting ∽∽────────────────────────∽∽ [Purpose of the lecture] The moth-eye structure created using biomimetic technology has an uneven structure of several hundred nanometers, which significantly reduces reflection in the visible light range. Due to its anti-reflection function, high contrast, and transparency, it is attracting attention as a structure that suppresses surface reflections and reflections for display applications. It is also expected to improve the brightness of organic EL and the power generation efficiency of solar cells. Nanoimprint technology is a microfabrication technology that uses a mold with minute
irregularities like a moth-eye structure to transfer shapes onto resin. In this seminar, we will explain the mechanism of the anti-reflection function using the moth-eye structure and the design concept of the structure. We will also introduce a simple simulation system for the anti-reflection performance of the moth-eye structure, and explain the elemental technologies for mass production of nanoimprints, such as roll-to-roll equipment, large-area molds, and UV resin. [Program] 1. Introduction 1.1 Functional film business development structure 2. Nanoimprint 2.1 Overview of nanoimprint 2.1.1 What is nanoimprint? 2.2 Elements in mass production 2.2.1 Large area mold using interference lithography 2.2.2 Roll-to-Roll device 2.2.3 Issues during mass production 3.

∽∽────────────────────────∽∽ Part 3: Anti-reflection and antifouling technology using silica nanoparticles ∽∽────────────────────────∽∽ [Purpose of the lecture] Silica, which is composed of elements that are abundant on earth, is an inexpensive, stable, and industrially important substance. Silica’s low refractive index can be used to create an antireflection film, and its hydrophilicity can be used to create a superhydrophilic film. Methods for producing antireflection films used for various displays, lenses, etc. include a dry coating method using sputtering or vapor deposition, and a wet coating method using a composition liquid. The former has excellent optical properties and film strength, but because it is manufactured in a vacuum system, it is expensive to manufacture and difficult to apply to a large area. On the other hand, although the latter method is not as good as the dry coating method in optical properties and strength, it can be manufactured over a large area and requires no vacuum equipment, so it can be manufactured at low cost. Silica has a low refractive index (n=1.46) and is physically and chemically stable, so it is often used in coated antireflection coatings. In order to make it difficult for dirt to stick or to make it easier to remove, it is effective to provide one of the following: 1. Water- and oil-repellent film 2. Super-hydrophilic film 3. Lipophilic film. General silica is hydrophilic, and a superhydrophilic film can be produced using a coating solution containing it as a main component. In this seminar, we will discuss examples of studies on single-layer antireflection coatings and superhydrophilic coatings using silica nanoparticles. [Program] 1. Silica nanoparticles 2.Anti-reflective film 2-1 Preparation of polysilane/silica nanoparticle hybrid thin film 2-2 Development of polysilane/silica nanoparticle hybrid thin film into antireflection coating 3.Superhydrophilic membrane 3-1 Features of superhydrophilic membrane 3-2 Preparation of superhydrophilic membrane using silica nanoparticles [Q&A] ∽∽────────────────────────∽∽ Part 4 Display anti-reflection technology and application development ∽∽────────────────────────∽∽ [Purpose of the lecture] In the CASE era, in-vehicle displays are becoming increasingly important. In addition to traditional navigation and entertainment, functions related to the overall operation of the vehicle are increasingly being controlled through displays. Inside a car, external light due to environmental changes greatly affects the visibility of displays, so it is important to take this into account in optical design that includes reflection characteristics. In this course, we will explain the basic content of the requirements for displays and the efforts to achieve them. [Program] 1.Automobile trends 1-1 What is CASE? 1-2 About hybrids, EVs, and fuel cells 2.Current status of in-vehicle displays 2-1 Situation of each region 2-2 About the supply chain 3.Requirements for in-vehicle display 3-1 Applications of in-vehicle displays 3-2 Requirements for in-vehicle display 3-3 Requirements for optical properties 4.About realizing optical properties 4-1 Current status of each method 4-2 Structure of in-vehicle display 4-3 About optical design 5.About key parts and key processes 5-1 Status of each part 5-2 About the cover panel 5-3 About bonding technology [Q&A] *Product and service names mentioned in this news release are trademarks or registered trademarks of each company. *The information contained in this news release is current as of the date of announcement.
