LG display reveals new four-stack WOLED panel

New panel type takes advantage of a 'Primary RGB Tandem structure'

We previously reported on the fact that Panasonic’s recently-unveiled Z95B Series of TVs were equipped with a brand new four-stack WOLED panel manufactured by LG Display. LG has just revealed details about the new panel type, which is claims can reach up to 4000 nits of white brightness, and up to 2100 nits of color brightness.

LG Display cites the panel’s ‘Primary RGB Tandem structure’ as the key to its innovation, echoing the nomenclature put forth by Panasonic.

“The Primary RGB Tandem structure applied to the fourth-generation OLED TV panel organizes the light source into four stacks by adding two layers of blue elements and independent layers of red and green elements,” explains LG. “It improves maximum brightness by increasing the amount of light produced by each layer compared to the previous structure.”

In addition to an increase in brightness, LG claims that the new panel type boasts 20% improved energy efficiency, as well as what it is calling a new ‘ultra anti-reflection filter.’

“…LG Display has developed a special film that offsets both light reflected from the display’s surface and light absorbed and reflected inside the panel,” the company explains. “With the advantage of this ultra-low reflection technology, the company’s fourth-generation OLED TV panel blocks 99% of internal and external light reflections, realizing perfect black just like in a movie theater with the lights off even in a midday living room setting (500 lux).”
