PHOLED will be the next giant leap of OLED TVs and screens

PHOLED will be the next giant leap of OLED TVs and screens. Display technologies are advancing and evolving rapidly and among those in which companies such as Samsung and LG are now interested, and consequently also Apple, there is a technology called Blue PHOLED (PHosphor Organic Light Emission Display), particularly interesting from the point of view of energy efficiency.

This technology – developed by Universal Display Corporation – has been talked about for some time, and among the advantages indicated, the solution to the problem of blue fluorescent-type emitters, which are less efficient and long-lived than the phosphorescent emitters used for green and red.

Blue OLED emitters with a high IQE (Internal Quantum Efficiency) should allow you to create long-lasting RGB OLED, WOLED and QD-OLED displays that are brighter thanks to blue emitters stacked in multiple layers.

The PatentlyApple website explains that Samsung and LG’s OLED displays for iPhones currently use patented technologies from Universal Display Corporation (UDC), a company headquartered in New Jersey and with offices in China, Hong Kong, Japan, South Korea, Taiwan and also in Ireland where it has recently announced the opening of a facility that will deal with the production of UniversalPHOLED materials.

UDC claims that blue PHOLEDs are 100% efficient, while fluorescent emitters only 25%, with a considerable increase in efficiency that could be added to other improvements offered by proprietary technologies from Samsung and LG. In this article we report an image and a video of UDC.

According to Michael Hack, Vice President of UDC, by exploiting the fluorescence offered by the technology in question it could be possible to improve the luminous efficiency of various products “up to 4 times” and consequently the battery life of various devices. Hack further explained that the use of this technology will be decided by their customers (companies of the caliber of Samsung Display and LG Display”. The first products with PHOLED displays could arrive starting from 2024.

Analysts and forecasts predict that Apple will use OLED screens in iPad and MacBook. But the Cupertino giant has been investing for years in microLED technology which seems to replace OLED screens later in the years: the first should be Apple Watch in 2025.
