For a couple of years, there are many high-end terminals that have decided to follow the same path that Samsung began with the first Galaxy S (10 years ago) by implementing screens with OLED technology, a technology that offers us some more vivid and realistic colors than traditional LCD screens.
However, this technology that little by little has been reaching televisions, is not ideal for this type of device for different reasons, something that is the QLED technology of Samsung technology that allows us to enjoy our television for more years without let's start suffer from problems with colors and brightness.
What is QLED technology?
Before the arrival of OLED technology to the screens of all kinds of devices, LCD technology was used, a technology that needs external lighting to be able to generate the image shown on the screen, hence the blacks are never black but rather dark gray.
OLED panels do not use exterior lighting, but rather each LED lights independently, so when black areas are displayed, they are actually black and not dark gray like LCD panels.
Samsung's QLED technology, like traditional LCD technology, requires an external light source, but it is an evolution of them. The main difference is that no need to illuminate the entire panel to display the image, but only individual pixels that have to display a color other than black can be lightened.
What benefit do QLED panels have over OLEDs?
Although OLED may seem like the ideal technology for large screens, it really isn't. The reason is none other than the marks on the screen that appear over time when displaying a static image continuously, such as the logo of a television channel or the status bars of video games.
If our television has begun to show marks on the screen, we must begin to consider changing it, since the only possible solution is to change the panel, the most expensive part of the television and that in no case compensates, since over time we will suffer the same problems again.
OLED panels do not use individual LEDs to display the image, so no at no time do they burn and leave marks on the screen. These panels illuminate only the pixels of the image, which allows us not only to enjoy a higher image quality, but also, we will not have problems with the duration of the television.
Samsung's QLED technology offers us a 10-year warranty
Quantum Dots, the technology behind these types of panels are some nanoparticles made of cadmium-free inorganic material (better for the environment) and it is practically impossible for them to show marks on the screen even if the device is at full brightness.
So confident are Samsung of this technology that They offer us 10 years warranty for screen marking. The QLED technology also allows us to enjoy 100% of the color volume regardless of the brightness of the screen, so we not only gain in durability, but we will also enjoy the best image quality currently possible in the market of the televisions.
OLED panels are ideal for smartphones and tabletsAs they do not show static images for many hours a day, it is not a good idea to buy an OLED TV for precisely the same reason. If you are thinking of renewing your old television this Christmas, Samsung offers us a wide variety of models with this technology, technology that also offers us a wide viewing angle.
