Why do monitors try to produce black light?

Wouldn't it be easier and better looking to turn the pixels off in the area where black color should be produced?

Yes that's why they do it that way.

Amoled

>what is backlight

Only OLEDs and CRTs work that way, not LCDs.

Only OLEDs can turn themselves completely off to produce black because each pixel lights itself up.

Normal LCD screens have an LED behind them producing a white light to light up the LCD panel.

LCD monitors have 2 settings for backlight, on or off

The pixels work independently of the backlight and there's no communication between the 2

plasma displays did that, but were ultimately murdered for cheaper to produce/purchase LCD techs.

plasma displays had pixels which were essentially florescent light tubes, doped with colored phosphorus to make RGB. each pixel or cell, made its own light, no backlight, no polarization filter, which is why plasmas had unlimited viewing angles. largest downfall was the increased energy usage compared to LCDs, and the complaints of sunlight on the glass screen.

i still say plasmas are superior, if there was more support for them (before everyone decided to stop manufacturing them) they could put almost any other tech to shame. cept were energy use is a concern

1440p 120hz OLED monitors when?

It's the backlight that causes that whitish black look, not the pixels

Soonish. Maybe next couple year or so
The new Thinkpad Carbon X1 touch screen version is OLED(or going to be OLED)

>tfw I still got my panasonic st50
It really is a bitch in sunlight though, even if it doesn't hit the display directly.

The thin CRT technology that got murdered by a patent troll would put everything to shame

You realize they all do that, right, but certain monitors have light bleed through, right?

They have light bleed through because they're shitty monitors that were produced cheaply.

Bought it in 2012. Wasn't even expensive. One of the best purchases I've ever done.

>cept were energy use is a concern

So most tablet and laptop screens. It's sad.

>LCD monitors have 2 settings for backlight, on or off

Uh... no. How the hell do you think brightness settings work?

>The pixels work independently of the backlight and there's no communication between the 2
This, on the other hand, is correct.

Well technically it's only able to be on or off, but it can do so very quickly.
