A New Tech Could Fix The Two Major Issues With OLED Screens Of Smartphones And TVs

A new display technology called "PHOLED" is expected to launch commercially in 2024, after several years of development by the Universal Display Corp. OLED.

What Happened: The blue Phosphorescent OLED (PHOLED) technology is expected to become available to manufacturers in 2024, allowing them to overcome issues affecting OLED technology currently used across smartphones and TVs.

OLED (organic light emitting diode) technology suffers from longevity and power efficiency issues. Display burn-in issues are also possible – sometimes, these burn-ins can be temporary, but permanent burn-ins deteriorate the user experience.

PHOLED technology is expected to fix these problems, but making it commercially viable has proven challenging.

One of the problems faced while developing PHOLED was the difficulty in getting the blue color to work without damaging the material that is used to generate it.

"We've had a lot of bright chemists and physicists working on this problem for years," Universal Display's vice president of business development, Michael Hack, told IEEE Spectrum.

According to Hack, the company has now figured out how to fix the shortcomings of PHOLED technology.

"A lot of research groups have worked on it, many people have published on it, but we believe we have it," Hack said.

Universal Display's Hack says the company is on the verge of initiating mass production of this technology.

"The more energy involved, the more likely bad things can happen, so it's been hard to get long lifetimes. But we will have it available in 2024," Hack added.

Universal Display showcased its advances in PHOLED technology in May at the SID Display Week event.

Why It Matters: The new PHOLEDs bring numerous advantages, including a more stable pixel structure, the potential for higher-resolution displays, a projected 25% efficiency boost, and a decrease in heat production, which should prolong the lifespan of adjacent electronics.

All these factors combined should improve traditional OLED displays’ longevity, brightness, and power efficiency.

Reduced heat generation should also improve the lifespan of other components like the battery and chipset, among others – heat is known to slow and even damage electronic components.

How long manufacturers take to implement this technology into their products remains to be seen.
