The competition among television manufacturers is entering a new phase. More and more companies are promoting RGB LED technology as the future of LCD screens and an alternative to OLEDs. Samsung, Sony, and Hisense are incorporating it into their most expensive models. However, TCL has taken a slightly different approach. Although it also offers RGB LED televisions, it has equipped its flagship model X11L with SQD-miniLED backlighting. The manufacturer argues that this is currently a more advanced and practical solution.
TCL is aiming for a larger number of local dimming zones
According to the company, the most important element affecting the quality of LCD picture is the number of local dimming zones. The more zones there are, the more precisely the TV can control the brightness of individual parts of the image. The flagship TCL X11L offers as many as 11,520 zones, while the RM9L model with RGB LED has 2,912. According to the manufacturer, a greater number of zones translates to better contrast, stronger HDR effects and less halo effect around bright objects. This is why TCL considers SQD-miniLED to be a more promising solution.
RGB LED has its own limitations
TCL also points out the phenomenon known as “crosstalk.” This involves the bleeding of colours between adjacent areas of the image. In practice, this can lead to situations where bright coloured elements affect the appearance of surrounding objects. The manufacturer claims that SQD-miniLED technology provides a more stable colour representation regardless of the scene. At the same time, the company admits that RGB LED can achieve slightly higher colour saturation in selected HDR materials. Ultimately, it all comes down to a compromise between a wide colour gamut and the precision of backlighting control.
TCL believes that at the current stage of LCD television development, the number of dimming zones is more important than the RGB LED technology itself. The company argues that SQD-miniLED allows for a more predictable and accurate image. Ultimately, the answer to the question of which solution is better will depend on practical tests and comparisons of ready-made televisions.
