It's important to remember that the terms "4k," "8k" etc. is shorthand that represents the horizontal resolution, not the total number of pixels (which is what matters when driving a display). 4k is the industry shorthand for a resolution of 3840 x 2160, which is about 8.3 million pixels. 8k is...

Why would you want a CRT with FALD? Firstly it doesn't make sense since CRTs aren't backlit, but secondly FALD is a bandaid for LCDs that tries to fix one of its main shortcomings by (poorly) approximating what CRTs already do perfectly: per-pixel light control with no bleeding. An LCD with FALD...

It's notable that the 32" panel with 4608 zones also has four LEDs per zone, which inclines me to think that it's for some other reason than processing power. My guess would be it's to average out any differences in brightness or color temperature between individual LEDs so at least each zone is...

BOE is a likely candidate. They have a panel that almost exactly fits the spec.

83 PPI https://www.calculatorsoup.com/calculators/technology/ppi-calculator.php

Very cool monitor, but 1440p and lack of VESA mounting make this overall a less versatile option vs. the 42" OLEDs. I was just posting about the reasons for keeping the PPI relatively low on OLED monitors in the near term; lower PPI is more efficient, which = higher brightness and longer...

Not that I know of. Although, all else being equal, smaller pixels need to be run harder to achieve equal brightness as larger ones, which increases power draw and heat output. So it may well be that a higher PPI panel would have more aggressive ABL.

Think about it like this: there's brightness, lifespan, and pixel density. If you increase any one, it reduces the other two. It's a balancing act.

OLED displays used in phones can be designed for high brightness because the lifespan is expected to be much shorter, and running at high brightness will age the emitters much faster, which is what causes burn in. The average phone screen is on for less than 4 hours a day, whereas a desktop...

I'm guessing any 27-30" OLED panels they make will be limited to 1440p, and 1080p for anything less than 27". The pixel aperture ratio probably gets too small for acceptable brightness/lifespan at higher PPI than that.

Can anyone using the QN90B as a PC monitor comment on the pixel bleeding issue described in this Amazon review?

There seems to be a tradeoff between brightness, lifespan, and pixel density with OLED, and increasing one spec reduces the other two. A 32" 4k has about a 26% higher pixel density than 27" 1440p, so I'm guessing they're trading lower pixel density for higher brightness and/or lifespan for a...

LG has a 240hz 27" 1440p panel planned according to tftcentral. Sounds like it will be WRGB.

I often see people conflating image retention and burn in when they really have nothing to do with each other. Even Vincent Teoh (HDTVTest) is guilty of this, and he should know better. Image retention is caused by charge build up in the cells. LCD, OLED, and plasma displays are all susceptible...

It does appear blue OLED + QDCC is patented by Samsung, so LG couldn't just straight up copy it. Could they do WOLED with QDCCs? Maybe, but it may not work as well for technical reasons. Ideally you use blue to downconvert to red and green. With white you might get unwanted wavelengths that...
