LOMOX® OLED Innovation

Major Market Opportunity for OLEDs in Flat Panel Displays and Low Energy Lighting

OLEDs are considered to be today’s “ultimate” flat panel display technology because of their:

  • Substantially reduced cost vs. liquid crystal displays (LCDs)
  • Potential for “roll up” displays on flexible substrates
  • Extreme thinness (less than 1 mm)
  • Light weight
  • Brilliant colours
  • Low energy consumption.

The replacement of existing light sources with OLEDs will reduce energy consumption substantially (by 60%) causing a major reduction of CO2 and positively impacting the greenhouse effect significantly. Compared to LEDs and fluorescent lighting, OLEDS

  • Generate more pleasing white light and better colour rendition
  • Enable “design colour” on demand
  • Provide new design opportunities for architects

Technology Solution

There are critical problems that exist with OLED technology in its present state. The technology is not scalable to large-sized displays (approximately >6” diagonal) at reasonable manufacturing costs. In addition, more than half the light generated is lost inside present-day OLED devices, causing the operating lifetime of screens to be unacceptably short. The OLED challenges for Low Energy Lighting are as follows:

  • Operational lifetime
  • Device Efficiency
  • Shelf Life
  • Production Costs

LOMOX® addresses these major problems through:

  • Fabrication of device structures with our patented materials by a very high-yield photolithographic process similar to those in the state-of-the-art semiconductor industry.
  • Use of holographically-generated nanostructures to eliminate the 50% loss of light emission in all OLED displays to date. Previous work has shown that reactive mesogen (i.e., polymerisable liquid crystal) OLED emitter materials can be photo-patterned into multicoloured display pixels with no loss in light output due to the photo-patterning process.
  • Delivering emitter materials with substantially improved chemical stability and better processes for incorporating them into OLEDs.

These new materials will yield long-lived easy and inexpensive-to-fabricate OLED displays.
