LG Display is one step closer to realizing the expected revolution in OLED display technology. The company announced that it has commercialized its blue phosphorescent OLED (PHOLED) technology, which solves the problem of the blue pixel, which is the biggest weak link in these displays.

LG is here with PHOLED displays

OLED displays create images by taking advantage of the light-emitting ability of organic compounds. These compounds use a structure containing fluorescent or phosphorescent. Phosphorescent materials consume less energy and have a longer life; therefore, they have been preferred for red and green pixels for years.

However, due to low efficiency and limited life on the blue pixel side, fluorescent-based solutions were still used. This was among the main reasons for problems such as screen burn-in.

As a result of its collaboration with Universal Display Corporation (UDC), LG Display developed a dual-layer panel architecture to overcome this structural problem. In the new blue PHOLED panels, one layer provides high-efficiency blue phosphorescent light, while the other layer contains a long-lasting fluorescent blue layer.

According to the company’s statement, the new technology will provide up to 15% energy savings in OLED TVs. This development directly translates to longer usage times in battery-powered smartphones, tablets and similar mobile devices.

Considering that LG Display supplies panels to major manufacturers such as Apple, Samsung, Sony and LG Electronics, it is expected that this technology will soon be used in a wide range of devices.
