realme has today announced the first SLED 4K smart TV in the world. This is a new peek in technology. Though the TV is not available for sale yet, it will present an interesting alternative to Quantum Dot based displays (QLED).

The SLED technology will launch on a 55-inch TV. The new type of panel is expected to deliver 108% coverage of the NTSC color spectrum, but will keep the amount of blue light under control, something that TÜV Rheinland has attested.

What is SLED?

It’s a new technology on the LCD formula, the main innovation concerning the backlight. Normally, the backlight is white, which is then fed through RGB filters to create the familiar color triplet.

Not same with SLED as the backlight uses red, green and blue LEDs to create the triplet. This is still an LCD, though, meaning it has polarizers and a liquid crystal layer.

How is SLED display technology different from QLED? This is different from QLED too, which starts with a blue backlight and uses quantum dots that absorb blue light and emit red or green. Then an LCD layer helps control the amount of light that passes through each pixel.

Anyway, the goal is not to get just any red, green and blue light, but to get the optimal wavelength for each color. This helps render a wider color spectrum and improves the image quality overall.

realme believes that SLED is a better solution to the problem than QLED. Competitors like Samsung and OnePlus already have QLED TVs in the Indian markets, this is realme’s attempt to trump them.
