I prefer LCD. AFAIK, all OLED screens on the market use PWM brightness control in the 100s of Hz range, which for many people causes phantom array effect during eye movement. LCDs can have DC backlights, avoiding this annoyance.
- Avamander 7y agoAlso most OLEDs have purple ghosting and burn-in which is annoying for many.
- shrimp_emoji 7y agoI've never noticed that. What I have noticed is OLED's true blacks. It looks great when reading at night[0] -- it's just the letters floating in darkness. With a backlit LCD, it's a moderately-bright gray rectangle with letters in it. 0: https://i.imgur.com/EpyXoAR.png https://i.imgur.com/EpyXoAR.png (FBReader with Monofonto font; book is one in The Hyperion Cantos series by Dan Simmons)
- JoshTriplett 7y agoFirst I've heard of that; interesting. From what I can tell, that's something software can potentially mitigate and smooth out on some displays?
- mrob 7y ago100% duty cycle PWM is the same as DC, so you can mitigate it by setting the hardware brightness to maximum and scaling image brightness down in software to compensate. This isn't a good solution because it sacrifices color bit depth, causing banding.
- opencl 7y agoSeveral of the Chinese manufactures have been adding a DC dimming mode to their recent OLED phones, i.e. Oneplus 7 and Xiaomi Black Shark 2.
