Paper-Thin, Ultra-Flexible MicroLED Display Technology

iBeam Materials Inc, a the leader in technology for large-area monolithic microLED displays, announced that it has successfully demonstrated the ability to make high-performance GaN Field-Effect Transistors (FETs) directly on thin, flexible and rollable metal foil substrates. These transistors can be produced without the need for a transfer step and can be integrated side-by-side with microLED emitters previously demonstrated by iBeam for use in a display. The monolithic process for integrated large-area microLED displays brings the industry closer to practical mass production and breakthrough applications. iBeam expects to see the technology available for large-scale manufacturing by 2022.
The advent of paper-thin, ultra-flexible microLED displays eliminates the traditional restrictions for the form factor of displays, redefining what devices look like and opening up the potential for a new class of mobile, wearable, lighting and instrumentation products. With a tough but thin form factor and a high level of flexibility, large-area microLED displays made with iBeam technology can curve, bend and conform to various shapes, radically departing from traditional planar forms. In addition, microLEDs offer extremely high brightness and much greater efficiency than traditional LCD and OLED displays. For more information see the IDTechEx report on Flexible, Printed OLED Displays 2020-2030: Forecasts, Markets, Technologies.
"This breakthrough in technology is a game-changer and brings us much nearer to the holy grail of displays," said Vladimir Matias, Founder & CEO of iBeam Materials. "We expect bright, bendable but tough, paper-thin and extremely power efficient displays to enable entire new classes of products. The new technology will rewrite the rules for the shapes of displays and products that use them."
The mass availability of microLED displays depends both on technical achievement as well as practicality of mass production. The breakthrough of iBeam Materials technology demonstration establishes that making these thin, rollable, next generation displays is now feasible. Earlier technology breakthroughs from iBeam include the patented process that allows manufacturers to deposit devices directly on a variety of substrates such as thin, flexible large-area metal foils. Producing microLEDs directly on a metal foil substrate, the iBeam technology enables roll-to-roll mass production. iBeam plans to demonstrate the scalability of robust manufacturing processes and the ability to produce these displays at much lower capital and operational costs than traditional displays.
"The iBeam promise of a paper-thin display made with transistors and emitters integrated into the same material and on flexible metal foil can lead to all kinds of new and interesting display products," said Ross Young of Display Supply Chain Consultants.
