Nowadays, there are various display technologies such as TV monitors, among which people may be relatively new to Micro OLED. This article will introduce what kind of display technology MicroOLED is, what features it has, and in what fields it has applications.
MicroOLED is a display technology that we mention less often and may not be introduced more than MicroLED, but in principle, its relationship with OLED, in general, is easier for us to understand than the difference between MicroLED direct display and MiniLED backlight.
Simply put, MicroOLED is an OLED with a smaller display area while maintaining a similar level of resolution, a feature that allows it to have a higher pixel density (PPI) and to be more widely used in all types of near-eye displays.
Compared to inorganic LED beads, it is relatively easy to reduce the individual pixel size of OLEDs, which is determined by the current vapor deposition process and the printing process that is under development. After the liquid organic self-luminous material is precisely placed in the designated area of the panel, the next problem to be solved is the addressing and driving of individual pixels.
The current variety of OLED screens are mainly used with active drive, which is often referred to as AMOLED, due to the volume limitations of MicroOLED, it belongs to AMOLED at the same time but can not use the more traditional drive method. Therefore, unlike the glass substrate used in conventional OLED and LCD screens, the substrate for MicroOLED uses a single crystal silicon wafer (wafer).
In addition to the common features of conventional OLEDs: single-pixel light control, high color gamut, and low response latency, MicroOLEDs also have the ultimate small size as their core advantage. Taking the MicroOLED product line launched by Sony Semiconductor as an example, some of the products are able to provide 2K-level resolution in the display area of less than 1 inch, and there are also 0.7-inch display products that focus on brightness to provide up to 3000cd/㎡ peak brightness with standard 1080p resolution and 3000+ PPI. At the same time, they have very low power consumption and can be widely used in a variety of portable devices.
Thus, the application scenario of MicroOLED is very clear, except for XR glasses and other AR and VR devices, it can be used in almost any kind of near-eye device that tries to replace the optical structure with a digital display. One of the most notable examples is the electronic viewfinder of Sony's own micro-single products.
Like such near-eye display needs, there are also electronic telescopes, electronic microscopes, medical endoscopes and other professional equipment, MicroOLED provides a quality solution for them, and more scenarios are being explored for their applications.
As technology advances, MicroOLED display will have the trend of display area toward larger or smaller, while continuing to improve the resolution, brightness, color and other picture effects, which will provide momentum for the development of smartwatches, smart glasses and other wearable devices, the effectiveness and charm of future augmented reality technology may be presented to us by this display technology.
