Sharp MicroLED Micro Displays Target Apple’s Goggles


Sharp developed a 0.38-inch full color panel featuring 1053 PPI and a 0.13-inch blue display with 3000 PPI, MicroLED display through its semiconductor subsidiary Sharp Fukuyama Semiconductor. MicroLED wafer base on silicon instead of sapphire is being used in some microLED micro displays  to potentially eliminate the transfer function.  Sharp is counting on Apple to be a major micro-LED customer and the company is allocating resources to that end toward the development of a high density near-eye display that Apple might use for the often rumored AR/VR glasses that are said to underdevelopment at Apple.  Thus far, Sharp’s Semiconductor subsidiary has produced a 0.38” full color micro-LED display with a ppi of 1053 and a 0.13” blue mono-chrome micro-LED panel with 3000ppi, but is looking at a 2023-2024 timeline for mass production.  A single color display, such as the one mentioned would need a conversion filter, likely quantum dots, to change the blue light to red and green, while the full color display would not.  Based on the concept of using micro-LEDs as self-emitting components, it seems self-defeating to use a monochrome display with a color filter.
