LED TVs and OLED televisions (organic LEDs) are famous for their low power consumption, superior image quality and brightness. However, LED TVs and OLED TVs are very different in terms of cost, life span, technology, and potential size.
It is said that OLED TVs have better image quality, consume less energy and have a much faster response time than LED TVs. But OLED technology is still relatively new, which means that OLED TVs are more expensive and their lifespan has not yet been tested if we want to compare it with the 100,000-hour LED life.
Although OLED TVs are thinner and weigh less, they are also smaller. Unlike LED TVs, which reach up to 90 inches, the largest OLED to date is only 55 inches, although this may change very soon.
LED indicates the light emitting diode. These are small solid-state devices that emit light due to the movement of electrons through a semiconductor. LEDs are relatively small compared to incandescent and compact fluorescent bulbs but can become extremely bright. However, LEDs are not small enough to be used as a TV pixel. That's why LEDs are only used as a backlight for LED TVs. LED TVs work using an LCD screen to control the luminous flux of LEDs that act as backlights.
OLED stands for organic light-emitting diode. Quite simply, an OLED is made with organic compounds that light up when fed with electricity. OLEDs can be made to be extremely thin, small and remarkably flexible. In an OLED TV, each pixel turns on independently of the others.
Dimensions and weight
With sizes ranging from a few inches to 90 inches, LED displays to have the advantage over other types of displays. The LED displays can be quite thin and light, but they are thicker and weigh more than the OLED counterparts due to the larger size of the LED diodes which give the display backlighting.
OLED displays currently reach 55 inches and do not have a wide range of sizes available for production. These televisions, however, are much thinner and lighter than their LED equivalents, since the size of the organic diodes is extremely small.
In terms of image quality, OLED surpasses LED TV in almost all aspects.
The best LEDs can have a reasonable apparent contrast ratio, although in general, they are mediocre. Because OLED can disable its pixels, it actually has an infinite contrast ratio, making OLED much better in this category.
The resolution for LED TVs has steadily increased over the years and, with some of the most recent displays, the number of pixels can go up to the 4000 range. OLED manufacturers, on the other hand, have only developed 1080p models.
LED TVs are extremely bright and therefore have a slight advantage over OLEDs in this category. OLED displays can also be bright, but running OLED pixels at maximum brightness for extended periods not only reduces the duration of the pixels, but pixels also take some time to return to total black. However, LED TVs are only technically brighter in general on a completely white screen. If a viewer thinks of a small white rectangle within a larger black screen, the OLED may appear brighter.
Although the LED has an excellent range of colors, the difference between the diode technology and the OLED allows the OLED display to create a significantly wider range of color space. This means that it can generate more colors with finer shades than its counterpart.
LED TVs have been around for a long time and have proven to last up to 100,000 hours of use reliably.
OLED TVs do not yet know how much life they have because of their recent development and their limited use in that time frame. Some colors within these types of displays may have different durations. As one color degrades, it will affect the rest, which makes this a problem. The compound used to create the blue color in OLED TVs is known to have a shorter life. Samsung seems to be fighting this problem by using a blue pixel that is twice the size of other colors and reducing the applied voltage. LG uses white subpixels and places a colored filter on them to create the desired red, green and blue colors. These bandages may very well work, but only time and use can tell how long OLED will hold up.
To begin with, LED displays to consume up to 20-30% less energy than other LCD displays. OLED displays are generally superior to LEDs in terms of energy consumption, use less energy in general and work more efficiently due to the ability of individual diodes to switch off without affecting the other diodes.
LED TVs actually try to block the light in the way they are designed. Therefore, due to the need of the human eye to capture light to see the screen, these televisions have non-optimal viewing angles.
While OLED TVs offer perfect viewing angles, since they produce light instead of trying to block it, the only models available now are curved. Secondly, due to the curve, anti-reflective coatings tend to dye the image if viewed from extreme angles. Also, in this case, the OLED technology is still superior in this sense in relation to the LED.
