What are the Peculiarities of OLED TV Technology?
OLED is a technology of screens with self-illuminating organic diodes that change colour independently of each other. Due to the fact that each point (pixel) is lit separately, the contrast of the picture is significantly increased, and the black and white areas of the image appear deeper and more natural. Disputes often arise among connoisseurs of modern technologies: to what extent do OLED (organic light-emitting diode) screens deserve the attention that has been paid to them lately? Is this really a step into the future and a worthy replacement for ageing LED monitors and TVs?
Main characteristics of OLED TVs
So, if an LED is a liquid crystal display with LED backlighting behind a panel, then in an OLED screen, each pixel is a light source that can change colour independently of its “neighbours”. This effect is achieved due to organic light-emitting diodes, each of which illuminates itself, as a result of which the contrast of the image is significantly increased.
When an LCD TV displays a picture that is completely black, you may notice that the picture is lighter in some parts of the screen. This is precise because of the backlight. As for OLED, when each LED is lit separately, the black picture will be absolutely black, and the contrast (the difference between the blackest and whitest pixel) is much higher than in LED.
OLED screens are often curved to provide extra depth to the image. The OLED display type has only gained popularity, and other large companies have also joined in the development in this area.
Main advantages of OLED technology?
Contrast. Talking about the benefits of OLED TVs, it’s worth dwelling on contrast in more detail. If for ordinary LED screens this characteristic has a value of about 1000: 1 (a white pixel is a thousand times brighter than black), and with a dynamic (change in brightness depending on the amount of dark or light colours on the screen) and local dimming value reaches 20,000,000: 1, then when using OLED this figure tends to infinity.
Colour rendition and viewing angle. Other advantages of OLED include a very high level of colour rendering and the ability to see a perfectly clear picture from any viewing angle. Therefore, this type of screen is the dream of connoisseurs of high-quality realistic images.
Dimensions. It was with the advent of OLED that it became possible to produce flexible screens on plastic film or metal. In addition, they can be made very thin (less than 0.2 mm thick) and lightweight without sacrificing functionality. This allows the development and implementation of fundamentally new design solutions.
Energy consumption. OLED is also characterized by low power consumption (due to the absence of additional backlighting).
Disadvantages of OLED TVs
Lifetime. According to experts, the main disadvantage of OLED displays is pixel burnout (especially blue colour), which, in turn, leads to colour distortion and loss of contrast. This will shorten the lifespan of the TV.
Brightness. An often-cited downside to OLEDs is also the fewer brightness levels. However, against the background of high contrast, this drawback is not so noticeable: there will still be no colour loss on high-quality OLEDs.
OLED technology is a significant breakthrough in the creation of crisp, high-contrast images on the screen. The high cost does not scare fans of a full-fledged OLED picture, which is difficult to compare with any other technology. Therefore, there is every reason to believe that OLED will be in demand in the high-quality TV market for a long time. To find the varieties of OLED TVs visit the PRC Direct website.
