A few years ago, a big-screen television using so-called “OLED” screen technology cost so much that it was out of the reach of most shoppers. But this year’s Consumer Electronics Show featured a flood of new OLED sets and prices have dropped enough to put them in reach of a lot more people. But what is “OLED” tech and how is it different from LED or LCD flat screens?
Organic Light-Emitting Diode uses a carbon film that allows diodes to emit their own light rather than using a backlight, as LCD screens do. The way OLEDs work allow them to create higher-contrast images and much darker blacks than LCDs, an advantage that older plasma TVs also had. Want more details? You can find that here.
Most of the major TV makers are jumping on the OLED bandwagon, but that doesn’t mean it’s the end of the line. Samsung recently claimed its new “Quantum” or QLED sets are even better. Let your eyes be the judge.
