OLED/mini-LED

Currently OLED has proven to be the best technology when it comes to color depth, viewing angles and contrast while maintaining relative low power characteristics. Furthermore there is no difference in response time over the whole of the operating temperature range.

The light structure and self-emitting technology makes it perfect for high end consumer and industrial applications. It is the most adopted technology when it comes to intelligent wearables and other leading technology applications and systems. It is becoming the most important display technology in mobile phones and increasing its market penetration in tablets and small to medium size laptops, especially those for image editing and high resolution drawings.

Those key features differentiate OLED from the markets dominating LCD (including TFT) technology, which is majorly depending of a front or rear light source. OLED doesn’t rely on a light source and is usually a lower power alternative.

The construction of an OLED takes less production steps and the display itself is ultra-thin. The thickness experienced by many customers is created by a glass substrate as a carrier. Prices may drop to a level where they are competitive enough to a TFT. Samsung and LG announced in 2020 to shut down their TFT factories and focus on OLED technology only.

In order to develop OLED market share, factories have developed a drop-in replacement for the common character and small graphic LCD modules. It has an identical structure like a COB type LCD and driving characteristics. DISvue® offers interchangeable OLED displays to directly replace e.g.a

2×8; 1 / 2×16; a 4×20 or 2×40 character LCD and several smaller graphic types like 128×64 and 256×64.

NOTE: OLED is a great technology that still needs to counter some drawbacks such as lifetime (different colors which have different lifetimes) latent image a.k.a. “burn-in” and pricing. The factories are working hard to improve these drawbacks and decrease them to a minimum.

 

MiniLED
A recent development to further improve image quality without drawback of current OLED displays is the technology referred to as miniLED. The LEDs are so small that they behave as a regular pixel. Technology companies like Samsung and Apple have already adopted to this new technology in the top line of their tablets. The miniLED displays are at this point mainly available to high volume consumer products, but this may change in the coming years.
