OLED: It's not perfect but it's close
Lower power consumption
- An OLED display doesn't need any of the electronics and circuitry used to drive the #led back light LCD shutter from a LED display, which makes OLEDs more efficient. LED screens produce black simply by fully closing the pixel shutter—the back light is still shining (it never actually turns off) but the light itself is being blocked. An OLED instead turns the pixel off entirely to produce the color black, saving energy in the process.
Better picture quality
- Since OLEDs incorporate their own color filters, they can produce deeper blacks and a wider gamut array. The lack of a permanently-on backlight promotes higher contrast ratios (the difference between the brightest and darkest pixels on the screen). And thanks to the lack of a shutter array, OLED displays can have refresh rates that are an order magnitude faster than those of LCD/LED sets. We're talking a boost from 480 Hz to 100,000 Hz—theoretically, at least. On top of that, OLEDs offer an impressively wide viewing angle—nearing 90 degrees off center for many panels—without the color and clarity losses seen in traditional LEDs.
Better durability and lighter weight
- Ditching the back light and shutter arrays also means manufacturers can replace the heavier, shatter-prone glass substrates often used in LED displays with lighter, stronger plastic substrates. And with the advent of injet-based printable OLEDs, these light producing compounds can be applied to more exotic and malleable surfaces. Additionally, the OLED films themselves are quite durable and can withstand a wider operating temperature range than regular LEDs without failing.
The price is only going down from here
- The ability to simply print out OLEDs as you would a term paper or silk-screened t-shirt holds incredible technological potential. It's also ludicrously expensive at present—look to spend about triple for an OLED set than a conventional LCD/LED these days—but once roll-to-roll production capabilities are scaled up sufficiently, the cost of spitting out an OLED panel should drop below what we're paying to make current generation LEDs.
