In 2017 the technology of the screens and televisions continues to evolve, and we’re getting into the 4K and the HDR (high dynamic range)… and soon in the 8K. And we still have to take a tough decision: OLED LCD vs LED: What technology is better? The iPhone X has already decided to go for an OLED display.
On the one hand we have the LCD technology, by far the most common type of screens that we can find. If you see a television described as ‘LED’ is actually an LCD display with a backlight.
On the other hand we have the OLED technology, which is used in phones like the Samsung Galaxy S7 and tvs such as the LG 65G6. Some people say that OLED is the future, but is much better than a good screen LED LCD?
OLED LCD vs LED: What technology is better?
What is OLED display? What is LED LCD? Differences between LCD LED and OLED
easily in one sentence: The LED displays LCD panels use a backlight to illuminate the pixels while the OLED pixels actually produce their own light, which means that the brightness of an OLED display can be controlled pixel by pixel. This type of control is simply not possible with a LED LCD.
In the cheapest tvs and telephones with LCD TV, the LED display lighting part of the sides of the screen. In the light of these LEDs then passes through a matrix that produces the red pixels and blue and green. So in the LCD LED screens, control over the level of brightness across the screen is limited and the blacks are not perfect.
OLED LCD vs LED: contrast
the tvs and monitors, we often see a contrast ratio quoted by the manufacturer. This tells you the amount of white brighter in comparison with the black, and a decent LCD screen may have a contrast ratio of 1,000:1 (whites are a thousand times brighter than black).
In an OLED screen, the pure black should not issue any light at all and you get an infinite contrast ratio.
There are LCD screens that replicate quite well the type of contrast that is obtained with the OLED display, are the so-called DLED Direct LED screens). Here, the LEDs are located behind the LCD panel instead of on one side, giving you more control over how brilliant are certain areas of the screen (you will find this technology in some high-end tvs).
Having said that, the technology is improving every day, and every time there are more tvs Direct LED with greater control over the brightness in each area of the screen.
And what happens with the Samsung TV QLED?
Comes to tie up a little more. What is QLED? Quantum dot LED, and Samsung says that it is better than OLED… yet it is not true.
The QLED is a more advanced form of LED display. In addition to a traditional LED backlight system, the layer of quantum dots allows light to specific pixel by pixel in a database using frequencies higher or lower: the blue light is controlled by the light, while the red and green light is tuned by the respective points in the layer of quantum dots. What consequence? We get an RGB image that is brighter and more vibrant than in an LED display and is less expensive to produce than a OLED screen.
What problem? This technology is still in need of a standard LED backlight to produce the image, which means that it cannot produce the pure black and the contrast lived an OLED display.
And it is that the TV is so cheap: TVC Samsung 55″ QLED QE55Q74K FAMTXXC, costs about 1800 euros.
OLED LCD vs LED: Image Quality
Both systems are able to play a very good image quality, especially if you have a High Dynamic Range (HDR). This is the abbreviation for a series of enhancements that allow the retention of the details in the darkest parts of the image, better color reproduction, deeper blacks and brighter whites: you must search for the tag ‘Ultra HD Premium’, which is found in both OLED tvs and LCD LED.
What then? Summarizing. LCD LED will never exceed to OLED in black levels, but OLED LCD LED exceeds the maximum brightness.
You will find the OLED technology on many high-end smartphones such as the Samsung models, while Apple, Sony or LG used
Why are there fewer OLED tvs?
Are more difficult to produce and only 3 companies (mainly) do: Samsung, LG and Panasonic.
One of the OLED tvs cheaper than you can buy right now is one of LG, the LG 55EG910V – TV DHF of 55″ (about 1300 euros), but you don’t have 4K resolution, something that is becoming essential in 2017. What OLED display with 4K resolution? LG OLED55B6V 55″ 4K Ultra HD Smart TV
If we are going to LCD tvs with 4K, the price decreases enough, to less than 700 euros (55-inch 4K resolution, smart TV): LED TV 55″ LG 4K 55UH605V
and what is going to happen in 2017? In 2016 the prices started to decrease and that is being felt in 2017. Looks that OLED tvs will begin to produce in greater quantity, which is probably cheaper costs, and will increasingly OLED tvs 4K at affordable prices.
In 2017 you can buy 4K resolution tvs with very affordable with LCD technology for about 600 euros. What OLED screens will become so cheap? We fear not, but their prices are still falling.
LG is the manufacturer that produces better OLED panels on the market. 10 this year have presented new models of OLEd tvs at CES 2017.

LCD screens on Blackberry smartphones can often seem sharper than the OLED displays with the same resolution
OLED LCD vs LED: Angle view
OLED screens tend to have angles of vision almost perfect, although often you can deal with a slightly different hue when viewed from a certain angle.
In LCD screens, the angles of vision vary enormously depending on the technology used. And there are a lot of different types of LCD panels, the panels with IPS technology that best results dan (is not exclusive to be LED LCD).
OLED Color LCD vs LED:
The latest LCD screens can produce great colors, but it depends on the specific technology used. IPS screens and can provide a great color accuracy when calibrated properly, but the screens TN can often seem faded.
OLED screens have an even greater potential to show an excellent color in front of the best LCD screens, but the problem here is that the content does not reach them to the height, and can cause a color too.
Conclusion: Comparative OLED vs LCD
If you have a limited budget you will end up buying an LCD screen, and does not have to be bad if is well made. Currently OLED screens are much more expensive, but it seems that the trend is about to change.
The OLED displays are more difficult to produce and offer a few black and perfect viewing angle. The color reproduction in both cases is very successful, especially with the presence of new production technologies. In short, the screen calibration is really important.
Watch out for! In 2017 the OLED displays are beginning to gain ground due to its lower price. Following being tvs more expensive, but not as much as in previous years.
