In the latest development of the ongoing intellectual property dispute between TCL and Samsung, a subsidiary of the Chinese electronics manufacturer TCL has initiated legal action against Samsung, Walmart, and Best Buy. The lawsuit, filed in the Eastern District of Texas, alleges infringement of three patents related to OLED display technology. This countersuit follows Samsung’s previous legal action against TCL in June, where Samsung accused TCL of violating its OLED patents.
The legal confrontation between these two industry giants underscores the competitive and litigious nature of the OLED market. Samsung has been actively defending its intellectual property rights in this sector. Notably, in March 2025, Samsung Display secured a favorable ruling from the U.S. International Trade Commission (USITC) against Chinese display manufacturer BOE. The USITC confirmed that BOE had infringed on three of Samsung Display’s OLED patents. However, the commission did not impose an import or sales ban in the U.S. against BOE, citing that the infringement had no significant impact on U.S. industries.

In a separate case, Samsung faced a significant legal challenge when a Texas federal jury awarded Pictiva Displays International Ltd. and Key Patent Innovations Ltd. $191.4 million in damages. The jury found that Samsung willfully infringed on two OLED display patents.

These legal battles highlight the complexities and high stakes involved in the OLED industry, where companies are vigorously protecting their technological innovations and market positions. The outcome of TCL’s recent lawsuit against Samsung and major U.S. retailers will be closely monitored, as it may have significant implications for the competitive dynamics within the OLED market.
