The ‘2022 OLED Components and Materials Report’
recently published by UBI Research (www.ubiresearch.com), a company
specializing in OLED market research, summarizes Samsung Display’s pol-less
technology development status and future roadmap.
Pol-less technology applies black pixel define
layer (BPDL) and color filter instead of polarizer. It is called ‘On-Cell
Film’ (OCF) at Samsung Display and ‘Color filter On Encapsulation’
(COE) at BOE and Visionox.
Pol-less technology was applied to 'Galaxy Z
Fold3' for the first time. Samsung Display announced that it can reduce panel
power consumption by up to 25% even at the same brightness by increasing the
light transmittance by 33% by applying pol-less technology.

'Galaxy Z Fold4' to be released in the second half of this year will apply RGB
resist in color filters as a low reflective material instead of pol-less
technology. Samsung Display's pol-less technology requires
two photo processes for TFT and five photo processes for color filter. In the future,
it is expected that the process time and cost will be shortened by reducing the
photo process 3 to 4 times by applying new materials.
Samsung Display is expected to further develop
pol-less technology and apply it not only to smartphones but also to IT
devices.
