I'm seeing "integrated heatsink for better burn-in resistance" in the description of all the OLED monitors slated to come out in 2024.
These marketing news stories on TPU miss the most important feature of these panels.
"
new W-OLED panel with an RGWB subpixel layout instead of the old RWBG layout, which should noticeably reduce fringing on small text and fine details."
"Samsung’s second-gen QD-OLED panel with an improved subpixel layout. It still uses the triangular layout, but text fringing is a lot less noticeable and won’t be an issue for most users."
Good read on the two technologies.
