Chinese consumer electronics company TCL has sued South Korea's Samsung in Los Angeles federal court, accusing its ​rival of falsely advertising some televisions as using "Mini LED" technology.

The lawsuit, filed on Monday, alleges that Samsung falsely marketed its M Model televisions as featuring the technology designed to improve picture quality.

Samsung "took a cheap, non-Mini LED model from a ​recycled product line and peddled it to the public as a 'supreme' ​Mini LED model at an attractive price point," TCL said.

Samsung ⁠said in a statement on Tuesday that it intends to vigorously ​defend itself against the lawsuit and stands "fully behind the quality and accuracy of ​our product descriptions."

"Samsung's false advertising misled consumers who wanted the higher picture quality associated with Mini LED televisions into buying Samsung's falsely labelled product, unfairly damaging TCL's sales, goodwill, ​and valuable technology in the process," TCL attorney R.C. Harlan said ​in a statement.

TCL's lawsuit said that the Mini LED technology in its televisions delivers "substantially better ‌picture ⁠with greater dynamic range and higher contrast ratios."

The company said it overtook Samsung in U.S. Mini LED television sales between 2023 and 2025 because Samsung failed to develop Mini LED televisions at a competitive price.

TCL said ​Samsung launched its ​M Model televisions ⁠in March at prices below TCL's cheapest Mini LED televisions and advertised them as featuring Mini LED technology. ​

But the lawsuit alleges that M Model televisions "contain none of ​the ⁠technological advancements associated with Mini LED technology" and are recycled from Samsung's standard LED televisions.

"This age-old tale of corporate greed proved successful, as Samsung's sham products ⁠stole ​back TCL's hard-won market share," TCL said.

TCL asked the court for an order blocking Samsung's "Mini LED" technology and for an unspecified amount of monetary damages.
