In the age of high technology, TV manufacturers are striving to create high-quality and competitive displays. Two leading monitor manufacturing technologies are QLED and OLED. In the article we will tell you more about each of them, consider all the advantages and disadvantages.
OLED and QLED Technologies: Features
The acronym OLED stands for Organic LED. To create multilayer structures are used, which consist of layers of several polymers. Main advantages:
- high brightness of the display, over 100,000 cd / m2;
- perfect contrast, saturated colors;
- wide range of temperature conditions;
- small display thickness;
- wide viewing angle.
Disadvantages:
- short life of diodes of individual colors (up to three years);
- high sensitivity to moisture;
- the high cost of creating technology for large matrices.
QLED displays are an LCD matrix with LED backlighting on quantum dots. Differ from LCD in wide color gamut.
REFERENCE! The first company to launch QLED TVs was Samsung.
Pros:
- lower price than OLED;
- energy saving compared to OLED is 30 percent higher;
- high brightness (about 2 thousand nits);
- the screen is not thin, it is more difficult to damage;
- large selection of display sizes.
Minuses:
- weaker contrast control function due to lack of local dimming function;
- not the maximum viewing angle;
- imperfect black color.
Thus, the image of monitors with organic LEDs is more realistic. But such models are much more expensive than quantum dot displays.
What is the difference between QLED, OLED and LED TVs
The most common type of display is LED / LCD. The image is created thanks to the filters of pixels. But in TVs using this technology, black is far from perfect. Consider the differences in technology according to several criteria.
Contrast
In displays using LED / LCD technology, the contrast depends on the following criteria:
- manufacturer;
- panel type;
- dimming function.
On OLED monitors, the contrast level is infinite, and the black level is perfect. Models of QLED TVs with the type of display VA provide a good level of black and high contrast.
Brightness
The brightness level is not a decisive factor, since its lack can be replaced by a deep black color.
Nevertheless, manufacturers pay great attention to the brightness of displays. The ideal level of brightness can be found in monitors with QLED technology (up to 2 thousand nits).
For 4K LED / LCD displays, this value does not exceed 700 nits. OLED has lower brightness than QLED. But due to the deep black color, the image transmitted by the monitor looks impressive.
Color rendering
4K TVs with LCD or OLED displays have an extended color gamut, realistic colors. Organic LED technology delivers the most natural colors. QLED have a high level of brightness.
Motion blur
The best technology for this criterion is a display with an organic LED. QLED monitors can quickly control pixel color changes. TVs with LED monitors are characterized by a short response time, only premium 4K HDR LED models provide high blurring characteristics.
Leading manufacturers of QLED and OLED TVs
Among the leading brands producing TV receivers QLED and OLED, there are several.
Sony
The image of the Japanese manufacturer is considered high quality, one of the best. Since 2017, Sony began to produce TVs with OLED displays.
Advantages:
- High quality.
- Solid design.
- A wide selection of diagonals from 32 to 100 inches.
- The use of various types of matrices.
- HDR support.
- Using advanced technology to enhance the image.
- High-quality assembly.
The Japanese manufacturer has practically no shortcomings. For the best models, the price is high, but it is justified by impressive characteristics.
LG
The manufacturer is ready to offer multifunctional and high-tech models using OLED technologies. Benefits:
- Convenient Smart TV platform with the ability to upgrade.
- A variety of diagonals with a resolution of up to 4K.
- Native Active HDR technology.
- Perfect viewing angle.
Since 2017, OLED displays have supported Dolby Atmos. The disadvantages include the lack of a headset jack on some models.
Samsung
The first manufacturer to launch models with QLED technology. Benefits:
- A variety of models with both direct and curved screens.
- Remote control with voice switching television channels.
- Application of advanced technologies for the best image.
- Convenient Smart.
The disadvantages include the not always high-quality Russian assembly and the overpriced price of some models.
Panasonic
Launches premium models using organic LEDs. Pros:
- Models support several 4K formats.
- Stable and easy to use Smart.
- Solid design.
- Reliability and multifunctionality.
The disadvantages include the high price.
The largest manufacturers of TVs do not cease to compete with each other, improving and improving the methods of manufacturing displays. OLED and QLED are very close in characteristics. Which manufacturer and technology to give preference to, is up to the buyer only.
