give a twist to Quantum Dots

January 7, 2026 by usatoday24

TCL has been one of the leading proponents of democratization of MiniLED panelstechnology that it has carried to its entire range from 2025. Therefore, it has not surprised anyone that in 2026 it maintains its commitment to this technology. However, your proposal is different from Samsung either Hisense that are committed to changing the backlight matrix with Micro LED RGB systems. TCL has presented at CES 2026 a new technology called SQD-MiniLED that promises to change the landscape of high-end televisions. The proposal consists of combining the Mini blue LEDs with improved quantum dots to maintain brightness. that Mini LED screens provideapproaching the color purity of OLEDs. SQD-MiniLED: Vitaminized Quantum Dots by TCL TCL’s new technology focuses on the quantum dot filter responsible for breaking down and filtering the white or blue light emitted by the MiniLED diode array. The SQD that has been added to the name of this technology refers to Super Quantum Dot (or super quantum dots), the filter that contains the Super QLED Crystalswhich represent an evolution in the performance of the QD filters used in their televisions today. As the brand explained, the improvement in color volume of this technology is notable. Conventional MiniLED televisions reach approximately 83% of the BT.2020 color space, while the new X11L SQD, the only TCL television that will mount this new system, promises cover 100% of BT.2020. That means purer colors and a more complete visual palette. In addition, the new light filter is complemented by a new UltraColor filter with ultrafine particles (5 nanometers) that carries out a second filtering pixel by pixel, thus avoiding color interference and reducing the effect blooming (that halo that appears around bright objects on dark backgrounds, like subtitles). More dimming zones, more light control However, the development of the SQD filter for MiniLED is not the only improvement that TCL proposes to improve the image quality of its future televisions. Most high-end MiniLEDs offer between 1,000 and 5,000 local dimming zones, which is not bad at all. The X11L SQD, on the other hand, multiplies that figure up to 20,736 dimming zones for the 98 inch model. This increase is also supported by a 26-bit backlight controller capable of managing millions of control points, what TCL calls Precise Dimming Series. This combination is important because more dimming zones mean tighter control over which parts of the screen should brighten and which should remain dark. When you view a scene with stars against a night sky, that granular control allows the stars to shine without the glare spreading to dark areas. This is what allows us to combine deep blacks similar to those of an OLED, with peaks of extremely high brightness. The X11L SQD that TCL has presented as a test table for its latest technologies reaches the 10,000 nits maximum brightnessthe upper limit allowed by the Dolby Vision HDR standard. The combination of 20,736 dimming zones, together with 10,000 nits of brightness and 100% BT.2020 coverage, results in blacks controlled with extreme precision and a wider color volume than those currently offered by conventional MiniLED televisions. However, improving the panel’s performance does not imply an improvement in itself if that improvement is not well managed. Hence TCL has developed the new TSR AI processor with Super Resolution to manage the new capabilities of your SQD Mini LED panel by applying AI algorithms. The TCL will arrive soon to the United States and will start at $6,999 for the 75-inch models, increasing to $7,999 for the 85-inch version and $9,999 for the 98-inch ones. The brand has not confirmed its arrival in Europe and Spain, nor its price for the old continent.

The hundreds of black dots on train and car windows are not a whim: they are a shield called ‘frits’

November 29, 2025 by usatoday24

Traveling by car or train means looking around the windows. You probably don’t just look at the landscape, but at all the vehicle interior elementsthe closest being the edge of those windows. A common element on the train and on the car window is a black border with a curious pattern of dots that become smaller as the rows increase. It is not paint or an aesthetic element, but something that fulfills a crucial technical function to protect the integrity of the glass. They are called ‘frit band‘ either ‘frits‘, and it is one of the most important passive safety elements that these vehicles have. The Science of Car Window Blackheads Although it seems like it, these dots are not paint: they are ceramics baked at very high temperatures, which fuses with glass during manufacturing of the same. He process It is most curious, since first the still hot black ceramic paste is applied to the edges of the glass, and then it is baked together with the glass in the tempering and bending process. In Xataka In 2001, Renault launched a car ahead of its time: it was a miserable failure that now has another chance It is a structural element of glass and this process involves a permanent bond that does not wear over time. The dot pattern motif, known as “gradient matrix”it is not a whim either, but a solution to something that could spontaneously break the car window. Black glass absorbs much more heat than clear glass, and this is something you can easily check on a sunny day: the black band will be hotter than the rest of the glass. When the temperature is extreme, and on trips where the moon can being hit by small stonesif there were an abrupt temperature transition between the black border and the transparent area, stress points would be created that could cause cracks. That’s why they pulled out that gradient that works like a processor heatsink: creates a thermal transition zone which distributes heat more evenly. It is something that provides protection to the glass, but they serve something else: to help the bond between the chassis and the glass. On the perimeter of the crystals there is glue that joins the elements, and the ‘frits’ have a rougher texture that allows a better adhesion from glass to chassis. Also, being black, they protect the glue against ultraviolet rays, maximizing its durability and the security of the union of the components. A detail from Jeep, which introduced an Easter egg in these frits In the end, what might seem like a simple aesthetic element fulfills an important safety function. In the train, this adhesion and thermal dissipation, and in the car, added to the above, greater resistance of the moon to shocks. In some cars it has been used to place a nod, and the fact that they are circles and not another geometric element has an aesthetic part, but also functional because it makes us overlook them while driving. It is one more example of all that everyday technology that surrounds us and that perhaps we always wonder if it would have some function, but once that initial curiosity passes, we forget to look.
