Which Tv Is Better Led Or Oled
The names of the technologies differ in only one letter, but the methods for creating the image are radically different. We will shed light on the possibilities of OLED and QLED TV screens.
Television technology today is experiencing a period of calm. Ultra HD 4K is already quite familiar in the market, HDR is gaining momentum, and streaming provides virtually unlimited availability of content at any time and in any conditions.
However, the confusion does not get any smaller: new abbreviations and marketing signs sprinkle like confetti at the wedding of the director of the confetti company.
Understanding them at times can be difficult, and most often the fault lies with the tricks of marketers. especially from the QLED camp. What is the difference between OLED and QLED?
OLED: Pros and Cons
OLED (Organic Light-Emitting Diode) is a technology for creating displays based on the fact that an organic carbon-based film is placed between two conductors that allow electric current, due to which the film emits light.
The main difference of this technology is that the light is emitted by each pixel separately, so that a bright white or colorful color pixel can be next to a pixel of black or a completely different color, and they will not affect each other.
This distinguishes them from traditional LCD panels, which are equipped with a special backlight, the light from which passes through a layer of pixels.
“With the LG OLED55B7V, you will always feel that you see exactly what was intended”
Other benefits of OLED technology are thinner and lighter panels compared to LED-backlit LCD TVs, a significantly wider viewing angle and a much shorter response time.
And the main disadvantage of OLED is the high cost of their production. are gradually becoming more realistic. in large part thanks to LG, the only manufacturer of OLED panels for TVs to sell them to other TV brands (such as Sony and Panasonic), increasing production and market competition. however, OLED TVs on. still remain much more expensive than models based on other technologies.
In addition, there are currently no OLED TVs with a diagonal of less than 55 inches on sale.
And finally, OLED TVs can not yet match the peak brightness with the best models with backlight.
QLED: Pros and Cons
The only major manufacturer who did not want to use OLED technology was Samsung, which preferred an alternative development called QLED.
QLED technology (Quantum-dot Light-Emitting Diode. quantum dot diode) theoretically has much in common with OLED, since each pixel also emits its own light, in this case using quantum dots. tiny fragments of semiconductors that are only a few nanometers in size.
“The biggest advantage of LED backlit LCD TVs relative to OLED models is their brightness”
Theoretically, such quantum dots are capable of creating incredibly bright, vibrant and diverse colors, surpassing even OLED in this respect.
The problem is that quantum dots in modern QLED TVs do not emit light; they have to rely on backlighting, just like the panels on conventional LCD TVs with LED backlight.
However, quantum dots still increase the brightness and control of colors compared to LCDs; however, this is still not the revolutionary technology of the new generation that everyone expected from QLED. it is rather a modification of the technology that Samsung used in 2016.
“The skin tones [of the Panasonic TX-55EZ95B] are perfectly balanced, they are distinguished by the naturalness of colors and a subtle elaboration”
But you should not write off QLED technology only because it does not correspond to the initial promises associated with the use of quantum dots. Judging by the models we have already studied, QLED TVs have a much brighter and more vibrant picture than their OLED competitors.
However, the need for additional illumination means that we will have to put up with the compromises of the LCD technology that we have been complaining about for so many years. And, of course, backlit QLED panels are not capable of being as thin as OLED. for example, LG TV’s OLED65W7 “TV wallpapers”.
But the main problem of this approach is that to illuminate small bright objects in the center of the screen, you have to significantly increase the overall level of backlighting, which negatively affects the depth of the black areas of the image.
The ability of OLED panels to highlight each pixel individually provides them with a significant advantage in this regard. Despite the fact that their overall brightness is inevitably lower, the contrast is simply magnificent.
If the image consists of very dark and very bright elements, OLED TVs are able to combine them much more efficiently, as demonstrated by Sony KD-55A1 and LG OLED55B7V.
The ideal technology will combine the brightness and brilliance of modern QLED TVs with black quality and incomparable contrast OLED panels, and most experts believe that this combination will be achieved in the next generation of panels in which quantum dots will emit light separately. and some manufacturers , including LG, is rumored to be already working on this.
Even on Samsung QE55Q7F it is sometimes noticeable that the level of darkness in these areas (especially black bars above and below the image when watching a movie) varies depending on the action on the screen, and this can be annoying.
How long to wait until the appearance of this next generation of QLED models is unclear. So today, TV buyers will have to choose one of two compromise options to their liking.
Judging by the models already familiar to us, the more natural and realistic image of OLED TVs seems more attractive than the energy of QLED competitors.
However, the current Samsung line is noticeably cheaper than the 2017 OLED models, so many potential consumers may prefer a QLED TV.
