TCL has emerged as a leading contender in the television market, particularly in the mini-LED segment. Over the past few years, the brand has rolled out exceptional models like the TCL QM851G in the U.S. and the TCL C855 in the U.K.

Recently, I attended a launch event where TCL showcased its 2025 lineup for the U.K. and European markets, featuring the latest C-series mini-LED models. These innovations are set to compete head-to-head with Samsung and Hisense’s premier mini-LED TVs. The event also included a series of engaging tech demonstrations, notably one that dissected the inner and outer mechanics of a mini-LED television.

Among the various demonstrations, three particularly stood out: a retrospective on TCL’s mini-LED technology, a deconstructed version of a mini-LED TV, and an analysis of how brightness levels fluctuate across different streaming content, specifically using Netflix as a case study.

The Evolution of Mini-LED TVs

The first demonstration focused on the evolution of TCL’s mini-LED technology, specifically examining 65-inch models from 2016 to 2025. The lineup included the 65X1 (2016), 65X10 (2019), 65C825 (2020), and 65C8K (2025).

Over the years, TCL has significantly enhanced the number of local dimming zones in its backlight systems. Starting with 288 zones on the X1 and escalating to 1,680 on the C8K, the differences in picture quality were striking when these models were displayed side by side. For instance, during a night scene from “Life of Pi,” the C8K expertly managed deep black levels contrasted against bright highlights, showcasing the advantages of more dimming zones.

When comparing daylight scenes, the C8K outperformed its predecessors in brightness and color accuracy. While the X10 displayed a decent performance, the C825 showed subtler color contrasts, particularly in the vibrant hues of the tiger’s fur. Ultimately, the C8K showcased how crucial the number of dimming zones is for enhancing picture quality in modern TVs.

A Deep Dive into Mini-LED Technology

The next highlight of the event was a demonstration of the TCL C-series mini-LED backlight, albeit without a screen covering it. Side-by-side comparisons of the flagship C8K and the mid-range C7K, both playing the same fireworks display, illustrated the C8K’s superior brightness and detail rendering.

Additionally, a deconstructed mini-LED TV provided insightful visibility into the various layers that constitute TCL’s television sets. Viewers could observe the mini-LED backlight array along with layers designed for light diffusion, enhanced color, and light alignment, all of which contribute to the vivid viewing experience.

Understanding Brightness in Netflix Streaming

Despite its popularity, Netflix’s streaming quality often lags behind Blu-ray due to bitrate limitations. For instance, a Netflix 4K stream averages around 17 Mbps compared to a Blu-ray’s 40 Mbps and can reach up to 128 Mbps for 4K Blu-ray. This difference impacts overall picture clarity.

During a demo, a Live Video Analyzer connected to a TCL C-series TV showcased not just color gamut coverage for various Netflix shows but also their average and peak brightness levels. Surprisingly, even popular titles like “Emily in Paris” averaged only 40 nits in brightness. The results were consistently underwhelming, with scenes from “The Crown” showing as low as 1 nit.

The conclusion was clear: while TCL’s TVs are capable of impressive brightness, not all the content you watch will fully utilize this capability. As consumers, it’s essential to keep these factors in mind when evaluating TV performance, especially in a world increasingly dominated by streaming services.
