Electronic & Imaging Materials Research Laboratories

The Electronic & Imaging Materials Research Laboratories was established in 1987, and conduct the following types of research on electro-coating materials, LSI assembly materials, display materials and printing materials, and in new fields such as organic electronics, environment/energy, and medical electronics.

The Electronic & Imaging Materials Research Laboratories is a central research facility for expanding Toray's business in information and communications materials/devices, and developing materials/technology for the environment/energy and medical electronics fields. Here we create advanced materials and technologies based on our world-class technologies such as functional polymer design and synthesis, fine patterning, nano-particle dispersion, and thin-film forming.

Electro-coating

This laboratories is developing innovative materials with Toray’s unique highly heat-resistant polymers, and using these materials in protective and insulating films for semiconductors and displays, and optical transparent materials for image sensors and touch panels.

Photosensitive polyimide PHOTONEECE™

Insulation layer and planarization layer for OLED

LSI assembly

Toray is developing sheet materials with photosensitivity and high thermal conductivity, thereby helping respond to greater fineness and 3-dimensionality, and to achieve downsizing of power devices. We are also developing release layer materials for laser lift off used in micro LED manufacturing process, and photosensitive conductive materials for electrode wiring.

High thermal conductive polyimide sheet FALDA™

Displays

This laboratories has created world-class technologies ーsuch as organic light emitting display (OLED) materials and insulation materialsーfor big-screen TVs and smartphones, and is researching flexible display related materials, organic wavelength conversion materials, and other new technologies.

Printing

We are striving for further evolution of our unique waterless printing technology, and developing CTP (computer-to-plate) Waterless Plates for direct imaging input from computers. For film packaging, we are developing water-soluble inks, and environmentally-friendly low-CO₂-emissions printing systems.

New fields

We are conducting R&D on parts for X-ray imaging equipment, next-generation communication materials, and secondary batteries, and applying these in the IoT and medical electronics fields.
