DisplayWeek 2019: Not Your Usual CES or E3 Convention

Last week, I went to DisplayWeek. DisplayWeek is full of engineers and manufacturer suppliers. It is not a media-heavy convention. I have posted an article DisplayWeek 2019 Photo Journal.

How were the viewing angles on the stacked LCDs?

Slightly worse than IPS but much better than TN!

Even viewed very off-axis, contrast-ratio remained extremely high, just there was a slight horizontal resolution loss effect because of the parallax. It wasn't noticeable for minor off-axis but noticeable at a 45 degree angle.

The cost of dual stack LCDs are predicted to be lower than flagship OLEDs.

Could you tell how good the backlight uniformity was?

Also, it sounded like they were saying it's actually each sub pixel being layered, is that correct? Are the layers actually so close together that it's accurate from a typical viewing angle? It seems like you could get some interesting artifacting if they aren't snug and perfectly aligned.

As far as I could tell in convention lighting and theater room, uniformity is better than all desktop gaming monitors as far as I could tell.

The layers seemed 2-3 millimeter apart from my guesstimate. It looked fine 10 degree off but I saw (tolerable) artifacts when 45 degrees off. The artifact seemed roughly akin to a halving of horizontal resolution when viewed 45 degrees off -- caused by parallax between the two layers.

Given the relative inefficiency of LCD and dual-stacking affecting this -- power consumption seemed surprisingly low -- most parts of screen were cool-ish or lukewarm -- so I'd guesstimate power consumption of a 65 incher stayed within a 100 watt average envelope or so. More than a single layer LCD, but still less than yesteryear's CCFL LCDs before the LED backlight era.

The panel refresh rate was 120Hz. Strobing, for motion blur reduction, should continue to remain suitable on dual-stack LCDs, assuming pixel response of both layers are sufficient fast. Dual-stack LCDs are theoretically cheaper to build than FALD backlights, though this particular dual-stack LCD was accompanied by a 100+ zone quantum dot backlight that helped keep the power consumption down, and provided what looked like OLED-league blacks.

Due to spammer robots abusing the PM feature, I had to disable PMs for new forum members until they have 5 posts.

Were there any MicroLED displays at this expo?
That's all I'm interested about.
