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 include it in their most expensive models. However, TCL has taken a slightly different approach. While 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 focuses on a greater number of dimming zones
According to the company, the most important element affecting the quality of LCD image is the number of local dimming zones. The more such zones there are, the more accurately the television 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 higher number of zones translates into better contrast, stronger HDR effects, and less blooming around bright objects. This is why TCL considers SQD-miniLED to be a more promising solution.
RGB LED also has its own limitations
TCL also draws attention to a phenomenon referred to 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 acknowledges that RGB LED can achieve slightly higher colour saturation in selected HDR materials. Ultimately, it all boils down to a compromise between a wide colour palette and the precision of backlight 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. However, the ultimate answer to the question of which solution is better will depend on practical tests and comparisons of finished televisions.
