Back in 2021, Samsung Display announced its Eco²OLED technology which increase light output by 33% (and reduces power consumption by 25%) by removing the polarizer OLED layer. The technology also reduces the panel thickness (by around 20%) thus making it easier to create foldable displays.

Samsung, which now brands the technology as On-Cell Film (OCF) OLEDs, and the company has announced that it has managed to optimize its design further and achieve a further power reduction of 37% and reach a maximum (peak) brightness of 5,000 nits.

Samsung's technology, as was disclosed back in 2021, replaces the polarizer layers with color filters. Samsung (together with its partners) developed three different technologies - a black Pixel Definition Layer (PDL), a new color filter design and a new black matrix (see image below). The main idea behind its polarizer-free OLED is that each sub-pixel in the display (red, green or blue) are separated from each other and so do not interfere one with the other. It's not clear whether the new 2nd-Gen OCF OLEDs are based on the same architecture.
