Now, with JBD’s Hummingbird I MicroLED projector reaching a new milestone at 6 lumens, consumer AR is on the verge of its next significant evolution. The new Hummingbird I optical module redefines AR capabilities, achieving an unprecedented 6,000 nits of brightness—a level never before seen in AR technology. This breakthro...

(Image credit: Samsung) Micro-LED TVs are something of a white whale for the biggest TV manufacturers. The display technology has plenty of potential, promising emissive pixels and infinite contrast without sacrificing brightness levels and deep blacks. It also doesn’t suffer from the degradation in performance associated with organic display types like the best OLED TVs. Thanks to how micro-LED TVs are manufactured – with clusters of “micrometer-scale LEDs”, or “almost microscopic lights” transferred onto larger LED mo...

(Image credit: Hisense) Although it might be known as delivering some of the best Mini-LED TVs in the market, Hisense is seemingly taking a new approach with an upcoming OLED TV slated to hit Europe this September. The new display, known as the Hisense A85N, is equipped with HDR10+, Dolby Vision support, and a purported 1,000 nits of peak brightness. It uses LG Display’s WOLED panel, which should give it quite the edge against major competitors Sony and Samsung. OLED tech isn’t exactly new for Hisense, as the display manufactur...

Lumileds’ R&D team realizes Lambertian distribution from microLEDs Lumileds has realized significant External Quantum Efficiency (EQE) performance for MicroLEDs in the past years. EQE, is the ratio between the energy contained in the light emitted from the LED and the energy in electrons injected into the semiconductor material. However, for microLEDs, and display applications in particular, EQE on its own is not a sufficient measure of performance. To properly assess the efficiency of a microLED, one must also be able to measure the direction...

Researchers based in China have been exploring the benefits of using freestanding (FS) gallium nitride (GaN) as a substrate for micro light-emitting diodes (LEDs) [Guobin Wang et al, Optics Express, v32, p31463, 2024]. In particular, the team developed an optimized indium gallium nitride (InGaN) multiple quantum well (MQW) structure with improved performance at lower current injection (~10A/cm2) and lower driving voltages as suitable for the advanced micro-displays used in augmented (AR) and virtual reality (VR) setups where the higher cost of FS-GaN can be compe...

Samsung Display is one of the biggest innovators in the industry. Among the wildest concepts the division has worked on over the years is the extendable display.
