Displays are devices for presenting information or recreating still or moving images. Numerous optical technologies are used in displays, including organic light-emitting diodes and inorganic light-emitting diodes, liquid crystals and fluorescent materials. Important considerations in display design are brightness, power consumption, range of viewing angles and colour reproduction.
Demonstration of holographic volumetric printing using time‑multiplexed holograms with laterally shifted Bessel PSFs for speckle‑reduced projection and a PLM‑based light engine enabling efficient phase‑only modulation for rapid 3D fabrication of multiscale objects with improved surface quality.
A perception-driven freeform eyepiece enables statically-foveated optical see-through head-mounted displays (OST-HMDs) with an 80° FOV and over 60 pixels per degree (PPD) peak resolution, delivering high perceived image quality while reducing pixel demand by over 35%.
The authors propose a 3D holographic method that generates physically consistent complex-valued light fields from multi-layer RGB-D data, achieving photorealistic defocus effects in scenes with transparency and reflection.
A full-colour 2D–3D switchable light-field display powered by a metasurface lenticular lens is proposed that is a promising solution for next-generation display technologies in both consumer electronics and commercial applications.
Photonics West 2026 highlighted how photonics research and innovations rapidly translate into commercial technologies, aligning with SPIE’s vision of photonics as a driver of economic opportunity.
A capillary-driven nanoimprint technology creates high-efficiency nanoscale quantum-dot light-emitting diodes (QLEDs) with sub-100-nm pixels, enabling ultrahigh resolutions of nearly 170,000 pixels per inch (PPI) for next-generation displays.
A study in Nature Photonics reports a miniaturized cascaded-diode-array spectral imager that enables electrically tunable spectral measurements from 365 nm down to 250 nm.
Full-colour tuning in rare-earth doped monolithic tellurite glass is realised via excitation pulse modulation, enabling a novel platform for laser-based transparent displays.
