Apple’s new Vision MR glasses, priced at $3,499, use cutting-edge display technology called micro-OLED. This sets it apart from more affordable options like Valve's and Meta's—which use different kinds of displays. Micro-OLED represents a significant advancement in screen technology, earning recognition on numerous "best TV" lists in recent years.
MicroOLED is a display technology that combines micro- and OLED (Organic Light Emitting Diode) technologies to create small, high-resolution displays. It consists of an array of tiny OLED pixels, each emitting its own light when current passes through it， fusing together into seamless images or textiles.
Technically, MicroOLED displays consist of several layers. At the core is the OLED layer, which contains organic materials that emit light when an electric current is applied. This layer is sandwiched between two electrodes, namely the anode and cathode. The anode injects positively charged holes into the OLED layer, while the cathode injects negatively charged electrons.
The OLED layer itself is composed of individual pixels, each containing red, green, and blue sub-pixels. These sub-pixels emit light of their respective colors when the appropriate electrical current is applied. By combining the emitted light from these sub-pixels, a full-color image is produced.
What sets MicroOLED displays apart is their small size and high pixel density. The individual pixels in a MicroOLED display are often microscopic in scale, allowing for incredibly high resolutions and pixel densities. This results in sharp, detailed images with vibrant colors and excellent contrast.
MicroOLED technology offers several advantages. It provides wide viewing angles, meaning the display can be viewed from different perspectives without significant loss in image quality. Additionally, MicroOLED displays offer fast response times, making them suitable for applications that require quick refresh rates, such as virtual reality and augmented reality.
These displays are energy-efficient as well since OLED technology allows for precise control of individual pixels. This means that only the necessary pixels are lit up, while others remain completely turned off, resulting in energy savings.
MicroOLED displays find applications in various fields, including AR/VR headsets, medical devices, automotive displays, and consumer electronics. Their compact size, high-resolution capabilities, and superior image quality make them a compelling choice for industries that require advanced visual display solutions.
