Summary of Key Points
TCL has filed a lawsuit against Samsung for false advertising regarding the 2026 M-series TVs, claiming they use Mini LED technology when they do not. This is the third time the two companies have gone to court in the United States in over a year. Although Samsung remains the second-largest shareholder of TCL CSOT, the competition in the market has intensified. At its core, this is a clash between a Chinese brand (TCL) seeking to enter the high-end market with Mini LED technology and a established player (Samsung) defending its position and profit margins in that segment. Behind the lawsuit lies the lack of industry-wide standards for Mini LED technology. The relationship between the two companies has shifted from a strategic partnership six years ago (a merger for complementary advantages) to full-scale competition. Such lawsuits are often a continuation of negotiations rather than a complete break.
1. Surface Claim of False Advertising, but Actual Struggle for Control of the High-End Market
The direct reason for TCL's lawsuit is Samsung's practice of marketing cheaper models as if they were Mini LED TVs. However, Mini LED technology represents a key opportunity for TCL to move into the high-end market. It represents a technology that offers clearer displays and better light control, making it an essential tool for Chinese brands like TCL to transition from the mid-to-low-end to the high-end segment. Industry data shows that TCL's shipments of Mini LED TVs more than doubled in 2025, allowing the company to charge higher prices. If the term “Mini LED” becomes widely used by all manufacturers, consumers will struggle to distinguish between genuine and fake products, potentially diluting TCL's premium pricing strategy. Therefore, TCL's goal is not just to address advertising claims but to maintain the definition of “Mini LED” as a high-end feature.
2. From Strategic Partnership to Rivals
Six years ago (2020), Samsung and TCL were complementary partners. Samsung, considering LCD technology to be outdated for the mid-to-low-end market, sold its panel factory in Suzhou to TCL CSOT for $1.08 billion and invested $739 million in the company, becoming its second-largest shareholder (12.33%). The arrangement was clear: Samsung would focus on OLED and high-end products, while TCL would take over LCD production, benefiting from Samsung as a major customer (accounting for 15% of TCL CSOT's large-size panel shipments). However, in the past two years, their roles have become more overlapping. TCL CSOT has acquired LG's factory in Guangzhou, developed printing OLED technology, and collaborated with Sony to compete with Samsung in the high-end market. In 2025, TCL sold 30.4 million TVs globally, just 5 million fewer than Samsung’s 35.3 million units, and even surpassed Samsung in December. This year, TCL formed a joint venture with Sony (owning 51% of the shares) in the home entertainment business, potentially overtaking Samsung as the market leader. Samsung’s remaining advantages are its high-end brand reputation and OLED patents, which are precisely the areas TCL is targeting. As a result, what was once a strategic partnership has turned into direct competition.
3. Lack of Unified Standards for Mini LED Technology
The complexity of this lawsuit stems from the absence of industry-wide standards for Mini LED technology. Questions such as the minimum size of the chips and the number of backlight zones are not clearly defined. This ambiguity allows both companies to claim their products as Mini LED, leaving the court as the venue for determining the standards. If TCL wins, the court will establish a definition of Mini LED that Samsung must adhere to; if Samsung wins, its products will be legally recognized as Mini LED, potentially eroding TCL’s competitive edge.
4. Litigation as a Tool for Negotiation
Such lawsuits are common in the industry. For example, Samsung has engaged in patent disputes with BOE, LG, and Chinese panel manufacturers, often resolving them through negotiations. The purpose of these lawsuits is not to determine right and wrong but to influence the terms of negotiations, such as sharing patents or dividing market shares. The ongoing partnership and supply relationships between TCL and Samsung demonstrate that their conflict is more about bargaining than a complete break.
5. The Rise of China’s Display Industry
This lawsuit reflects the growth of China’s display industry. Chinese companies are moving from focusing on scale (acquiring Samsung and LG’s panel factories) to pursuing higher profits in the high-end market. As a traditional player, Samsung is naturally trying to protect its high-end position. The inevitable outcome of this competition is the clash between new and established players. If industry standards do not keep up with technological advancements, litigation may become the most cost-effective way to resolve conflicts. Both companies are using lawsuits to pressure each other into making concessions.
6. The Inevitable Conflict in the Transition to High-End Markets
This conflict is also a result of the transformation of China’s display industry. While Chinese companies have grown in scale, they now aim to transition from low-profit, mass-market products to high-value, high-end products. Samsung, as a established player, is defending its market position. If industry standards cannot keep up with technological developments, litigation may become the primary means of resolving these structural tensions. The court’s decision will only be temporary, and the ultimate outcome will depend on the negotiations between the two companies.
In summary, this lawsuit is not about who is right or wrong but about a battle for control of industry standards as Chinese brands strive to enter the high-end market. It represents a necessary part of the industry’s transformation. For the general public, this conflict highlights China’s manufacturing efforts to move from a large-scale producer to a competitive player in the global market.
