Can Samsung Kill LG OLED with Quantum Dot Technology?
- Samsung developing QLED TVs
- Potential for better picture quality than LG's OLED
- Technology 3-5 years away
You might remember that LG OLED killed it at CE Week’s TV Shootout. When pitted against Samsung curved, Sony 4K and VIZIO Ultra HD TVs, LG OLED came out as the decisive winner.
And yet, CNET states that Samsung, who has denied plans to produce its own line of OLED (organic light emitting diode) TVs, is still top dog in the TV manufacturing game. That's a title that could be hard to keep when left with only LCD (liquid crystal display) technology that's been around for decades.
But what if something better than OLED was out there?
Samsung has confirmed that it is currently developing QLED TVs for the commercial market. According to CNET, QLED (quantum dot light emitting devices) has the potential to match the ‘infinite’ contrast ratio of OLED, with better power efficiency, better color and more.
QLED TVs emit quantum dots, microscopic molecules that, when hit by light, emit a different colored light. “Quantum dots let LCD TVs offer wide color gamut without losing a significant amount of light output.”
The problem is that LCDs can’t match the contrast ratio of OLED or plasma TVs. Per-pixel control is needed to create next level picture quality. That’s where electroluminescent quantum dots come in.
Instead of an LED supplying the light for the quantum dots, electroluminescent quantum dots glow directly from supplied electrons.
According to CNET, this ability is the key to better picture quality.
OLED TVs use yellow and blue OLED materials to create “white” light, which is filtered using RBG and clear color filters. This is similar to how LCDs create color.
A large benefit is that this makes the TVs cheaper to manufacture. The downside is that getting a wide color gamut is more difficult.
RGB OLED, the next logical step, is more difficult to manufacture in large sizes.
Quantum dot technology has a lot of potential. Direct-view electroluminescent QLED TVs are still 3 to 5 years away. In theory, QLED has the potential to match or succeed OLED performance while boasting a wide color gamut and lower power consumption.
Guess we'll just have to wait and see.
