Researchers based in Korea report on size-dependent characteristics of indium gallium nitride (InGaN) red micro-scale light-emitting diodes (micro-LEDs) fabricated on 4-inch silicon (Si) substrates [Juhyuk Park et al, Optics Express, v32, p24242, 2024]. The team from Korea Advanced Institute of Science and Technology (KAIST), Korea Advanced Nano Fab Center (KANC), and Chungbuk National University, sees its work as being pioneering, adding: “This work is the first investigation into the size-dependent characteristics of InGaN/GaN red micro-L...

Los Angeles-based Q-Pixel has developed microLED display technology which it says has achieved the highest resolution, active-matrix colour display in the world. Q-Pixel’s display offers 6800 pixels per inch (PPI), surpassing current displays. The technology replaces the traditional three subpixel LEDs with a single polychromatic LED. Q-Pixel has fabricated its display entirely using microLED pixels, technology which has been notoriously challenging to implement. Unlike most advanced VR displays, which use micro-organic LEDs (micro-OLEDs), Q-...

Jun. 3, 2024 ---- Efforts to reduce the cost of Micro LED chips through size miniaturization are ongoing. Companies like LGE, BOE, and Vistar continue to invest in large display applications, while AUO has been focusing on developing smartwatch products. There is also growing demand for new display applications in head-mounted devices and for automotive uses. TrendForce’s “2024 Micro LED Market Trend and Cost Analysis Report” reveals that the market value of Micro LED chips is projected to reach $580 million by 2028, with a CAGR of 84% f...

The Micro LED development was hit hard in March 2024 after Apple decided to cancel the Micro LED watch project. Slowdowns in aspects including investments, technological development, and widespread use are unavoidable. Nevertheless, chip miniaturization, which is closely associated with cost reduction for Micro LED chips, continues to move forward. LGE, BOE, Vistar, and other manufacturers have invested in large-sized display applications, while AUO continues developing its watch products. Regarding novel display applications, Micro LED can be seen in head-...
