Realme is a Chinese company known mainly for cheap phones, but it has just revealed a TV technology that shows you the handicap of Samsung’s QLEDs.
When it comes to TVs, the best performers in the world in terms of contrast and the number of colors they can display are still OLEDs. For this reason, they are also very expensive. This does not mean, however, that there is no fierce competition in the mainstream area, where Samsung makes the law with its QLED or Quantum Dot LED.
To the surprise of many, Realme unveiled the first 4K TV whose panel uses SLED technology. It is not for sale yet, but since the presentation, the advantages over QLED have become obvious. In the first phase, the SLED will reach a 55-inch TV.
The new screen technology has already been certified by the TUV Rheinland authority and they have confirmed that it is capable of reproducing 108% of the colors specific to the NTSC spectrum. At the same time, however, it will significantly reduce the amount of superfluous blue light specific to QLED.
As a reference, SLED is a significant upgrade to the LCD formula, just like LED or QLED. The revolutionary change is related to the liquid crystal panel lighting solution. Typically, an LCD is backlit with a white panel, whose light output passes through RGB filters to create a familiar image.
In the case of SLED, the backlight is made with red, green and blue LEDs to create the triplet needed for a vivid and contrasting image. Unlike OLED, however, the respective backlight system is still installed behind a layer of liquid crystals.
Realme is convinced that the solution they found for SLED is significantly better in terms of color and color accuracy compared to QLED. As for the technology that Samsung is fighting with its fist, it uses a blue backlight system, and through “quantum dots”, the blue light is absorbed, and in its place is emitted blue and green light. . Then, an LCD layer helps to enhance the amount of light that passes through each pixel.
