Presentation Abstract

From Diffractive Lightfield Backlights to Switchable LC Cells: Practical Paths to Scalable Immersive 3D Immersive 3D is experiencing a renaissance, highlighted by the recent launch of mass-market products from Samsung, Acer, ZTE, Lenovo, and others. In this talk, I will review the underlying display architectures that have enabled this transition, comparing Leia’s earlier diffractive lightfield backlight (DLB) approach with our current front-face switchable LC cell technology. I will discuss key trade-offs in optical efficiency, form factor, cost, color fidelity, and temporal modulation, as well as the growing importance of software—particularly calibration, lens defect compensation, and predictive eye tracking. The presentation will share practical insights gained from bringing immersive 3D systems from research into large-scale production.

The Role of Organic TFT (OTFT) in the New Era of Flexible Displays and AR optics

Mike Banach – VP of Technology, FlexEnable Technology Limited

Presentation Abstract

The market for flexible displays is growing rapidly, and the technology to address the opportunity is diversifying. The performance and production processes for organic thin-film transistors (OTFTs) have been optimized to meet this demand, leading to FlexEnable’s recent historic breakthrough: bringing OTFT to mass-market for the first time. The Ledger Stax crypto wallet by Ledger, featuring an OTFT ePaper display uniquely wrapped around a 180-degree bend, is a prime example of the design freedom afforded by this innovative technology.

FlexEnable has developed a fabrication process that allows complete liquid crystal (LC) cells and OTFTs to be manufactured on plastic films instead of glass, utilizing standard flat-panel display equipment. These flexible, ultra-thin and lightweight OTFTs open the door to new product form factors and enable multiple applications – from wrappable displays to pixelated dimmers for all day-wearable AR glasses.

This talk will describe the development path for OTFT and showcase the current state of art performance. I will detail how OTFT can be combined with various display technologies and how the unique manufacturing approach has also laid the groundwork for an exciting range of LC optics applications.
