Next, we will make a comparison between AMOLED vs OLED vs LED vs QLED: Which is better and what are the main differences between these screens? You will find the answer below. Undoubtedly, this information will help you choose your television. You will more easily answer questions such as whether Roku TV screens or any other brand are good.
LED screens
As its name indicates, LED screens are made up of small LEDs that together are capable of forming images. As you can imagine, LED televisions or screens contain a large number of LEDs and are characterized by offering a vibrant color image, usually more prominent than that of LCD televisions, but they also generate problems such as screen tearing.
Regarding its operation, LED technology panels have a large number of white LEDs, which are responsible for illuminating the pixels. This has the great disadvantage that the blacks never become so deep, since the white lighting is always present on the back to illuminate and give the image that the screen shows.
This technology, although cheaper, has some problems (beyond the one mentioned above in relation to blacks). A detail to consider is that these panels have reduced viewing angles, in other words, you have to see them from the front to get a prominent image.
OLED screens
It is a substantially more expensive technology than LED, however, OLED offers in most cases a much more outstanding image. This is largely due to the operation applied in this type of panel.
OLED panels do not have a system of white LEDs that illuminate a rear panel as in LED TVs/Monitors. In fact, they only have one row of LEDs, which is responsible for showing us the image. In other words, it is the LEDs themselves that show us the image, which clearly has a few advantages.
The main and great advantage of OLED panels is that each LED can be turned on and off individually. This change, although it seems subtle, greatly helps the quality of the image and mainly creates deep blacks, since the pixel is completely turned off.
QLED screens
QLED technology is a variation of LED technology, only, unlike the previous one, the color management is different. In this case, we have the so-called quantum dots, which are the ones that control the colors in these panels.
Certainly the general process is somewhat complicated to explain, but these televisions usually have a color quality superior to that of LEDs. However, on certain occasions these colors can be so vibrant that they appear unnatural.
AMOLED screens
Mobile technology is so advanced that there are even screens with 90 Hz or 120 Hz, we also have technologies such as AMOLED. AMOLED, refers to a variation of OLED technology, in fact, it is practically the same but focused on the world of cell phones. The technology was patented by Samsung and therefore it is very common to see it in its superior devices.
Either way, it’s fair to point out again that AMOLED is the same as OLED. Therefore, it has the advantages and disadvantages of this technology, only this time it focuses on cell phones.
In any case, for mobile phones this screen is usually highly recommended. As we pointed out before, you can create deep blacks by completely turning off pixels, something that in addition to image quality can also help with battery life.
AMOLED screens keep their colors vivid even when the glass breaks. In this case, it is convenient to use Cracked Glass Repair Kit to repair a mobile screen, which can help to recover the beautiful image produced by AMOLED panels.
