OLED technology has evolved a lot in recent years and can be found every time. Panels with higher image quality. The latest expression of these screens in televisions is Samsung’s QD-OLED technology and LG’s microlens matrix; the latter is a response to the increasingly prominent Samsung panels.

However, one aspect that is open to improvement is the energy efficiency section. We know that OLED panels consume much less energy than the LCD type, as they do not have a continuously backlit panel. LEDs made of organic materials they turn on and off on demand depending on each scene.

The final cry of OLED technology may pass make use of phosphorescent materials in the blue subpixel. Universal Display Corporation (UDC) insists that this will be a major innovation and also the way OLED panels become much more efficient.

PHOLED will help make OLED technology more efficient

Light emission from OLED panels can be divided into two types: fluorescent and phosphorescent (PHOLED). Currently OLED panels already offer phosphorescent emission in red and green subpixels, but blue subpixel remains fluorescent due to technical and economic limitations. According to Universal Display, fluorescence emission uses only 25% of the emitted light, while phosphorescence uses 100% of the light.

The fact of making the blue subpixel emit phosphorescent type light It can increase the efficiency of the panel by 4 timesAs Mike Hack, vice president of UDC, pointed out a few months ago. It also recently made a statement based on this new technology, guaranteeing that its PHOLED technology will reduce energy consumption by 25%.

Regarding production costs, Hack added: “Using blue phosphorus in panel material costs will be profitable because the proportion of using blue phosphorus is very small.” This means that although blue phosphorus was priced high in the first place, it will be priced high in the future. The price increase will be balanced by considering the advantages of these panels in terms of both brightness and energy saving.

According to the hack, each company has its own plans for applying phosphorescence to the blue subpixel. He also managed to say a few words about the Micro OLED display of Apple Vision Pro and made the following comment: We expect the use of this technology to increase significantly We think more manufacturers will start using Micro OLED in their VR/AR headsets in the coming years.

Waiting for the preparations to be completed Mass production of PHOLED panels will be completed around 2024. According to Hack, there is no change in production planning, so it is possible that we may see the first devices to adopt these screens when the first units of these panels are produced.

Probably the first devices to include PHOLED panels laptops, tablets and even virtual and augmented reality devices. The purpose of UDC is to bet on PHOLED in the long run, so if these panels live up to their promises, we may see this technology implemented in television panels in the future.
