I've recently been learning about how fonts render based on subpixel layouts in monitor panels. Windows assumes that all panels use RGB layout, and their ClearType software will render fonts with that assumption in mind. Unfortunately, this leads to visible text fringing on new display types, like the alternative stripe pattern used on WOLED monitors, or the triangular pattern used on QD-OLED.

Some third-party tools exist to tweak how ClearType works, like MacType[1] or Better ClearType Tuner[2]. Unfortunately, these tools don't work in Chrome/electron, which seems to implement its own font rendering. Reading this, I guess that's through FreeType.

I hope that as new panel technologies start becoming more prevalent, that somebody takes the initiative to help define a standard for communicating subpixel layouts from displays to the graphics layer, which text (or graphics) rendering engines can then make use of to improve type hinting. I do see some efforts in that area from Blur Busters[3] (the UFO Test guy), but still not much recognition from vendors.

Note I'm still learning about this topic, so please let me know if I'm mistaken about any points here.
