Samsung sues TCL over OLED display patents in latest legal salvo

Samsung TCL Lawsuit

Samsung has filed a fresh lawsuit in a Texas federal court accusing Chinese smartphone maker TCL and its affiliates of infringing multiple OLED display patents. The suit also names two U.S.-based companies, Ultimate Eshop LLC and eTech Parts Plus LLC, which Samsung says are selling or importing replacement OLED displays that violate its patents.

In the filing, Samsung claims that TCL China Star Optoelectronics Technology Co. and Wuhan China Star Optoelectronics Semiconductor Display Technology Co. are producing OLED panels that infringe on three key patents: U.S. Patent No. 9,330,593, No. 7,414,599, and No. 11,594,578. These patents cover OLED pixel circuits and driving methods.

Samsung says it notified TCL of the alleged violations back in July 2022 but claims the company has continued to produce infringing displays. The complaint specifically targets OLED screens used in several TCL smartphones sold in the U.S., including the TCL 10 Pro, TCL 20 Pro 5G, TCL 30, TCL 30 5G, and TCL 30+.

Samsung TCL Lawsuit

The legal battle builds on a prior case at the U.S. International Trade Commission (ITC), where the ITC ruled that Samsung’s patents were valid and found that certain companies, including eTech Parts Plus, had infringed them. TCL had attempted to intervene in the ITC case after replacement OLED panels it produced surfaced in the U.S. market.

Samsung is also leaning on a recent win at the Patent Trial and Appeal Board (PTAB), which last year upheld the validity of two of the contested patents, bolstering the company’s legal position.

Samsung declined to comment on the latest lawsuit. TCL and the U.S.-based companies named in the suit have not yet responded to requests for comment.

Apple’s Foldable iPhone Could Fuel Big Gains for TCL CSOT

Apple-Foldable-Concept

Apple is expected to enter the foldable smartphone market in 2026, and its arrival could significantly impact the display supply chain. According to a new report from Counterpoint Research, global shipments of foldable smartphone panels are forecast to grow 46% year-on-year, with Apple’s panel procurement plans playing a major role in driving that increase.

While Samsung Display is projected to lead with a 57% market share, TCL CSOT is quietly emerging as one of the fastest-growing players in the foldable panel segment. Counterpoint estimates that TCL CSOT will see a 47% year-on-year growth in foldable panel shipments in 2026, placing it ahead of several competitors in terms of momentum.

The report highlights a shift in consumer preferences toward book-style foldable devices with large, inward-folding displays. These designs are gaining traction in both global and Chinese markets, where buyers are prioritizing screen size and productivity features over compact form factors. Samsung’s Galaxy Z Fold 7 has already outsold the Flip model in early sales during the second half of 2025, underlining the trend.

Global Foldable Smartphone Panel Shipment Share

Panel makers are expected to post uneven results next year. BOE may experience an 8% decline, while Visionox is projected to grow 8%. Tianma is forecast to achieve the highest year-on-year surge at 580%, though from a smaller base. TCL CSOT’s 47% growth positions it as a key player poised to benefit from rising demand and higher average selling prices.

Counterpoint also expects foldable smartphone shipments to grow 14% in 2025 and 38% in 2026. As Apple prepares to enter the market and push foldables into the mainstream, TCL CSOT appears well-placed to expand its presence in the global foldable display market.

In related news, TCL CSOT is supplying the display panel for AOC AGON’s 1000Hz gaming monitor, the AGP277QK, while TCL has also launched the PlayCube, A1S, and C1 portable projectors in the UK.
