There has been a lot of talk about OLED but it is only now that the generational shift from LED to OLED is running seriously. But those who keep track of the market may have heard QLED as well, and it’s hard to know what’s a better option. We figure out what’s what.
To distinguish between OLED and QLED can be difficult. The names of the technicians make them look similar, but it’s quite a big difference when you learn more about them in depth. In practice, there are two completely different technologies. They, in turn, give completely different results regarding image quality.
QLED builds on LED technology. It refines it and improves colority. While OLED is a very own technique created to take a holistic approach to image quality.
“OLED is a big step forward on the technology side, almost as it went from black and white to color. If you watch a TV that looks positive in the store, you can almost be sure it’s because it’s an OLED TV, “says Pär Josefsson, Product Manager at Philips TV.
This may be the reason why many TV manufacturers have hoped for the OLED train.
OLED TVs are often found among the top models. Previously, you needed to pay quite a bit for them, but prices have fallen.
“The production of OLED panels has become more efficient and technology has evolved. This makes it possible to find OLED models at a fair price, “says Pär Josefsson.
Differences between LED, QLED, and OLED
A TV with OLED technology can turn on and off each individual pixel in the panel separately.
This means that the noise can be controlled at the precision level, all the way down until all LEDs are extinguished, and the pixel becomes completely black. The result gives a striking blackness in the picture.
“The extreme blackness that can be reproduced reinforces both the clarity of the colors and the detail domain,” says Pär Josefsson.
With LED TV, the TV’s LEDs (backlight) can only be switched on and off in one or a few larger zones. No pixel will be completely black – even if so required.
QLED, in turn, builds on LED technology and puts a layer of nanocrystals behind the LCD panel. The crystals send light in red, green or blue. This makes the TV reproduce colors much better than it had done with standard LED technology.
Not only the panel that counts
TVs with OLED often has striking image quality. But in order for the TV to be able to utilize OLED technology seriously, a powerful image engine is also required. The sword may otherwise take over and the detail will be lost in dark parties.
be lost in dark parties.
“We have a picture engine called P5, which is especially designed to fit well with OLED panels. If you have a simpler picture engine, you get very much with OLED but lose the details in those areas, but with a good image engine like P5, it retains the details. Likewise the color. The OLED panel has a very wide color scale. The picture engine is important here too, so that you fully utilize the technology,” says Pär Josefsson.
Philips combines OLED technology with its popular feature Ambilight, which makes their models stand out on the TV market. Ambilight makes the image perceived as more contrast-rich, and also generates light flows around the TV. This makes the image look bigger than it actually is and TV viewing is more enjoyable.
OLED technology televisions are also extremely thin because they do not require any backlighting. This also provides new possibilities with the design.
