The QLED is closer in tech to the old LED and LCD TV because it sports LED backlights, with the only difference being QLED’s use of quantum dots or QD.

WHATEVER brand your OLED TV may be, its panel is made by LG Electronics.

If money is no object and you want the latest and the greatest that TV manufacturers have to offer, then some of the very best big-screen television models, at least on paper, were unveiled during the 2020 Consumer Electronics Show (CES) in Las Vegas.

Samsung showed off its Q950TS 8K QLED, LG displayed the GX Gallery Series OLED, Panasonic re-positioned itself with the HZ2000 OLED, Sony left mouths gaping with the A8H OLED and TCL staked its claim to quality affordable big-screen TV with its 6-Series 2020.

Don’t go looking though for the said models anytime soon on showrooms because they will only start trickling down for actual sale probably by the next holiday season.

What buyers may consider, at least as tested by Tech Radar are the following brands and models that are on top of the heap and are presently available in stores, with their own strengths and weaknesses.

These are the Samsung Q90R QLED TV, LG C9 OLED Series, Vizio P-Series Quantum X, Samsung Q900R QLED TV, Sony A9G Master Series OLED, LG B9 OLED Series, Samsung Q70R QLED TV, TCL 6-Series QLED (R625), Hisense H9F Series and Sony Bravia X950G Series.

Insofar as resolution is concerned, 4K is a must for televisions ranging in size from 50 inches up. The old full high-definition 1080p resolution would simply not cut it for huge screens because of lesser pixel density and smaller dimension of actual image.

Without being technical, the less dense is pixel count, the less details will be visible for viewers; the smaller the dimension of the actual image the worse it would look when blown up.

Presently, there’s already 8K that simply upscale videos, including those shot natively in 4k resolution. In time though, videos shot natively in 8K would be more prevalent.

Another thing to consider are the vastly different technologies used by TV manufacturers to light up the screen. For Samsung and TCL, that would be QLED or “quantum dot” light emitting diode while for the top of the line of LG and Sony, OLED reigns supreme.

The QLED is closer in tech to the old LED and LCD TV because it also sports LED backlights, with the only difference being QLED’s use of quantum dots or QD.

QD are molecules that emit differently colored lights when hit by white light from LED. The dots are sandwiched in a film and, along with an LCD layer, create the picture.

OLED stands for organic light emitting diode and it is closer to plasma in technology than to LED. The individual diode in OLED lights up independently of one another, thus black can be blacker while minute lights on a scene — say the stars in an science fiction movie — would have clarity that would be lost in ordinary LED TV or even in QLED.

In CNET’s side-by-side comparison, OLED sets have generally delivered better overall image quality than QLED TV, in the same way that plasma always looked better than LCD and LED TV.

LCD being the backing technology of QLED is cheaper to manufacturer thus QLED TV are generally cheaper than OLED TV of the same sizes. As OLED also do not use backlights, they boast of thinner panels.

Sony, Panasonic and Philips all manufacturer OLED TV, but all use OLED display panels manufacture by LG.
