Clokwork My Search has found that nobody makes panels like this. Due to the fact that DC dimming causes color inaccuracy, most manufacturers don’t want to implement it. Such a shame.
JTL Clokwork From what I've seen all OLED panels have the brightness "dip" in accordance to refresh rate even without explicit PWM. That being said I don't think anyone's ever measured the old (i.e Galaxy S1/S2) OLED panels that were in use before Samsung popularized PWM dimming across the industry.
JTL Clokwork Curiously I've seen this claim in a review of a Samsung OLED TV. Not sure I believe it. First because Samsung, and they don't demonstrate the waveform changing. The Samsung S95B isn't technically flicker-free, as there's a small decrease in brightness that corresponds with the refresh cycle of the display. This is very different from pulse width modulation flicker (PWM) on TVs with LED backlights, and it's not noticeable. This dip isn't even always there, and the display is flicker-free in the following modes: PC Mode: only with the brightness at max Dynamic Mode: brightness above 20 Standard Mode: brightness above 48 Game Mode: brightness above 25
Clokwork JTL good call. The only future tech I know about that could solve this is micro led, but they will find ways to mess it up for us. Micro led has the potential to stop temporal dithering too but my expectations are low. There’s that and the roadmap doesn’t seem to have panels in our hands until after 2030.
JTL Clokwork You can allegedly buy a microLED panel for a nonrefundable payment on the order of several multiples of ten thousand dollars. Something I'd pass on. However I'd be interested to know if it were possible to view a microLED panel in a "showroom" or similar. If possible and I could visit there's a chance I could bring my oscilloscope and photodiode to conduct some measurements.
Clokwork JTL I understanding your concern. the frame rate dip makes sense but I have my huge doubts as well that the display doesn’t utilize PWM. As far as I know, PWM is the only way for displays to keep their color accuracy. I’ll take DC dimming any day over PWM. The larger concern for me though is the Temporal dithering. I suffer from LCDs with this as well, for example any recent model ipad.
JTL Clokwork Well, DC dimming was the subject of your post so I'm discussing what I know. Temporal dithering and other alleged visual artifacts is a different problem.
Apple-Meta-USA Correct! OLED only have DC-Like-Dimming! Which is better than PWM, but still flickering. Such as LG C2, C3 and so on!
