Sept 1 (Reuters) - Chinese ⁠consumer electronics company TCL 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 Samsung falsely marketed its M Model televisions as featuring the technology, which is 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 labeled 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 an unspecified amount of monetary damages.
