LED monitors

[Mike Kujbida]

A friend of mine started using one recently and found that it was a lot easier on his eyes.

Other than a very few OLED devices, when companies say “LED” monitor these days, they mean LCD with LED backlight. Usually, this also means some kind of dynamic LED backlighting.

A normal LCD is like a shutter — it can transmit light or block it, but it’s only do good at blocking it. Thus, the typical 1000:1 or so contrast ratio of an LCD display, versus 15,000:1 from a CRT. Common cheap LCDs also have a limited color capacity, often only a functional 6 bits per pixel (for TN displays; MVA and IPS, and the many other variations, generally address this problem).

So anyway, the LED idea is pretty cool. Early dynamic LED/LCD displays used multiple LEDs lighting at the edge of the display. By modulating the LED as well as the LCD, they could increase the effective dynamic range of the display. More recently, backlit LED/LCD displays use individual displays for increasingly smaller blocks of pixels. So they can extend the dynamic range increasingly further.

It’s a real improvement, particularly good for video rather than computer displays, which is why TVs have been using this for a few years, and it’s only now showing up in monitors (well, and the fact that monitors are increasingly just using television panels). Just keep in mind you’re still primarily an LCD display.
