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+.

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.

TCL C6K QD-MiniLED TV Series Launched in Europe with 144Hz Display and Gaming Perks

TCL TV C6K Premium QD-MiniLED TV

TCL has launched the C6K QD-MiniLED TV in European markets following its debut in India in May. The model appears under different names depending on the region, including C61K and C69K.

TCL C6K QD-MiniLED TV Specifications

The C6K supports multiple HDR formats, including Dolby Vision IQ, HDR10+, and HLG. The high peak brightness level allows viewers to see clear images even in bright rooms. TCL includes a High Vertical Alignment (HVA) panel with a native contrast ratio between 6000:1 and 7000:1, depending on the model. The panel also offers a wide viewing angle and power-efficient performance.

The TV supports a native 144Hz refresh rate at 4K resolution. TCL has included Variable Refresh Rate (VRR), MEMC 120Hz motion smoothing, and AMD FreeSync Premium Pro to improve the visual experience during fast-paced gaming and video playback. Features like Game Master Mode, Gamebar, and Superwide GameView add additional customization and responsiveness for gamers.

TCL uses its in-house AiPQ Pro Processor to enhance picture quality in real time. The chip performs pixel-level image adjustments and adapts brightness and contrast based on ambient lighting. The AI Contrast feature improves detail visibility in both dark and bright scenes by adjusting the image according to the viewing environment.

The C6K comes with an integrated 2.1-channel Onkyo speaker system. TCL includes independent subwoofers on the back of the TV to deliver deeper bass. The audio system supports Dolby Atmos and DTS Virtual:X, which aim to provide immersive, multi-directional sound without requiring external speakers.

The TV runs on Google TV and supports Google Assistant voice commands. It includes HDMI 2.1 and HDMI 2.0 ports, USB 3.0, Ethernet LAN, and Wi-Fi 6. TCL has also received TÜV Rheinland certification for low blue light emissions, which may help reduce eye strain during extended viewing sessions.

TCL QM5K QD-Mini LED TVs launched in US with premium display tech, HDR & gaming features

TCL QM5K QD-Mini LED TV

TCL is expanding its QD-Mini LED ambitions in the US with the launch of the new QM5K series, a feature-packed 4K smart TV lineup designed to strike a balance between premium performance and accessible pricing. Positioned as the entry point in the brand’s 2025 Mini LED range, the QM5K sits just below the more advanced QM6K lineup and follows closely on the heels of TCL’s flagship Q8MK debut.

TCL QM5K QD-Mini LED Specifications

At first glance, the QM5K doesn’t scream “entry-level.” It borrows much of the premium DNA from TCL’s higher-end sets, starting with the QD-Mini LED backlight system paired with the company’s new Halo Control System. This combo, now trickling down to more affordable models, allows the QM5K to push for deeper contrast and brightness precision, with up to 300 local dimming zones (LD300) helping it deliver richer blacks and more controlled highlights.

Color performance is similarly ambitious. Thanks to its QLED layer, the TV achieves vibrant, punchy tones while maintaining accuracy across a wide gamut, ideal for HDR content. Speaking of which, TCL packs the QM5K with nearly every major HDR format: Dolby Vision IQ, HDR10+, HDR10, and HLG, all covered under its HDR Pro+ umbrella.

TCL’s AIPQ Processor sits at the core, dynamically optimizing contrast, color, sharpness, and even backlighting in real-time, based on the input signal. It also powers Motion Rate 240 with MEMC frame insertion, a tech cocktail designed to reduce blur and improve clarity for fast-paced scenes, be it in films or competitive gaming. For gamers, TCL throws in its Game Accelerator 144 tech (on 55-inch and up), along with Auto Low Latency Mode (ALLM) for responsive, lag-free gameplay.

Audio isn’t an afterthought either. Models 55 inches and above include an Onkyo 2.1-channel speaker system with a built-in subwoofer. TCL also supports Dolby Atmos and DTS Virtual:X for immersive 3D sound, even through the TV’s onboard speakers.

Design-wise, the QM5K aims for minimalism. It’s ultra slim, with discreet cable management and easy-access ports, all wrapped into a clean aesthetic that won’t look out of place in modern living rooms. It runs on Google TV, supporting both Chromecast and Apple AirPlay 2, and integrates smoothly with Google Assistant, Amazon Alexa, and Apple HomeKit for voice control.

TCL C8K QD-Mini LED TV series launches in Europe with premium display and audio features

TCL C8K QD-Mini LED TV

TCL has launched its new C8K QD-Mini LED TV series in Europe. This lineup is identical to the TCL QM8K series released in the US last month. The European version, also known as the C81K in some markets, had already been previewed in April. It is now available in countries including Spain, France, and Italy.

TCL C8K QD-Mini LED TV Specifications

The C8K series uses TCL CSOT’s CrystGlow WHVA Panel with an almost bezel-free ZeroBorder design. TCL claims the panel offers 40 percent wider color viewing angles compared to previous models and significantly reduces glare with its anti-reflective surface. The combination of ultra-thin bezels, improved panel construction, and aerospace-grade aluminum alloy gives the C8K a premium, modern appearance.

Each TV in the series features TCL’s Halo Control System. The system enhances color accuracy and gray scale performance while reducing blooming and halo effects. The new Super High Energy LED chip and Super Condensed Micro Lens allow for better light control. The series also integrates TCL’s Micro OD technology, which minimizes the optical distance between the backlight and diffuser plate to improve image clarity.

The C8K supports up to 3,840 local dimming zones and achieves a peak brightness of up to 5,000 nits on the 98-inch model. The panel delivers a native contrast ratio of 7,000:1 and covers 97 percent of the DCI-P3 color space using advanced Quantum Dot technology.

The series also includes TCL’s Zero-Delay Transient Response technology, which minimizes lag between the input signal and backlight response. This ensures clearer motion and more accurate rendering of fast-moving content. Gamers will benefit from a 144Hz native refresh rate and Game Accelerator 288Hz support, along with AMD FreeSync Premium Pro certification.

The C8K features Audio by Bang & Olufsen, with up-firing Dolby Atmos drivers for immersive audio performance. The TVs also support Dolby Vision IQ, HDR10+, and IMAX Enhanced certification. TCL has added a new backlit remote and hands-free voice control.
