TCL CSOT to Announce Gen-8 Inkjet OLED Investment Soon, Achieves 350PPI Milestone

SID Display Week 2025 TCL IJP Monitor

TCL CSOT is preparing to announce its Gen-8 inkjet-printed OLED (IJP OLED) production line investment between August and September this year. Zhou Mingzhong, Head of Technology Planning at TCL CSOT, confirmed the development during an interview after the Seoul Display Business Forum. The company is currently discussing the project with local authorities, which has slightly delayed the official announcement.

TCL CSOT has achieved a pixel density of over 350 pixels per inch (PPI) on its inkjet OLED panels. The company uses an RGB sub-pixel arrangement with equally sized sub-pixels, which eliminates the size imbalance typically seen in FMM OLEDs, especially with the larger blue pixels. Zhou stated that the blue OLED device’s LT95@100nits lifespan will reach 400 hours by 2026, a tenfold improvement over 2020 figures.

The company claims its inkjet OLED panels have an aperture ratio three times higher than conventional fine metal mask (FMM) OLED displays. This improvement is expected to enhance brightness efficiency and extend the overall durability of the panels.

TCL CSOT currently operates a Gen 5.5 inkjet OLED line at its T5 facility in Wuhan. It manufactured 21.6-inch medical OLED panels using this process in late 2024. The new Gen-8 line will support larger substrates, which are better suited for televisions and monitors.

During the forum, Zhou also highlighted potential applications for the technology. TCL CSOT has developed a 6.5-inch smartphone panel with 325PPI, a 14-inch 2.8K laptop display with 243PPI, a 27-inch 4K monitor with 163PPI, and a 65-inch 8K TV panel with 136PPI. The company displayed several of these prototypes at SID 2025.

The Gen-8 investment marks a strategic step for TCL CSOT as it aims to compete with South Korean display makers in the high-end OLED market.

Hisense G7 Ultra monitor unveiled with 1152-zone Mini LED, 4K 160Hz/1080p 320Hz modes

Hisense G7 Ultra

Hisense has announced the G7 Ultra gaming monitor in China, a 27-inch display designed for high-end gaming and professional content creation. The monitor will launch on September 26, with pre-orders now open across major platforms in China.

Hisense G7 Ultra Specifications

The G7 Ultra features a 4K FAST IPS panel and a 1152-zone Mini LED backlight system. This configuration enables precise brightness control and minimizes blooming. The panel reaches a peak brightness of 2000 nits and carries HDR1400 certification. Hisense has equipped the screen with its Obsidian Screen technology, which reduces reflectivity to just 1.8 percent and maintains visual clarity in bright environments.

The monitor supports two refresh rate modes. It runs at 160Hz in 4K resolution and 320Hz in 1080p mode. It also supports FreeSync Premium and achieves a 1ms GTG response time. An AM driving chip manages each dimming zone to improve contrast and detail uniformity. Hisense has also included a custom halo-control algorithm, adapted from its Mini LED TVs, to maintain consistent brightness across the panel.

Color performance is a major focus. The G7 Ultra covers 99 percent of DCI-P3, 99 percent of sRGB, 100 percent of Adobe RGB, and 85 percent of BT.2020. The monitor achieves ΔE<2 color accuracy and includes a quantum dot film layer to enhance color vibrancy. It supports 10-bit color depth (8+FRC).

Hisense G7 Ultra

For connectivity, the G7 Ultra includes HDMI 2.1, DisplayPort 2.1, USB-C with 90W power delivery, USB-A, USB-B, and a headphone jack. The USB-C port supports KVM switching and reverse charging. The monitor also features DC dimming and blue light reduction modes.

Hisense uses a Moon Shadow Gray finish for the chassis. The stand supports height, tilt, swivel, rotation adjustments, and VESA mounting. Hisense includes a factory calibration report, multiple cables, and a three-year on-site service warranty.

TCL SQD-Mini LED Tech Explained: New Benchmark for Mini LED Displays

TCL SQD-Mini LED

TCL SQD-Mini LED (Super Quantum Dot Mini LED) technology is the company’s most ambitious evolution of Mini LED to date. Debuting with the flagship X11L series, this new display tech is designed to overcome the limitations of conventional RGB-Mini LED systems by delivering better color accuracy, more efficient light control, and higher brightness, all while allowing for ultra-slim TV designs.

In traditional RGB-Mini LED setups, backlighting is achieved using red, green, and blue LEDs grouped together to form white light. While this allows for rich colors, it comes with downsides—namely, the potential for color bleeding, limited zone density due to complex layouts, and inconsistent performance when rendering mixed-color scenes.

SQD-Mini LED solves this by switching to a single-type blue LED light source, which passes through a high-density layer of upgraded quantum dots. These dots convert the blue light into red and green wavelengths, which are then blended to produce full-spectrum white light. The result is purer, more stable colors with minimal distortion.

TCL SQD-Mini LED

Unlike RGB-Mini LED, which achieves only localized high color gamut (often peaking at around 97% BT.2020), TCL’s SQD-Mini LED panel delivers a true global high color gamut, reaching 100% BT.2020 across the entire screen. It maintains consistent accuracy whether the scene is monochromatic or multi-colored. Because each pixel’s color generation process remains uniform, there’s no shift or compromise during complex scenes.

This architecture also makes the backlight more compact and thermally efficient. A single chip can replace a cluster of three RGB LEDs, allowing more dimming zones within the same area. In the case of the X11L, the 98-inch version reaches 20,736 zones—an industry-leading figure. Brightness is another strong point, with peak levels hitting 10,000 nits, ideal for true HDR playback.

SQD-Mini LED also enables thinner TVs. The X11L is just 2cm thick, making it the slimmest Mini LED TV ever. In short, TCL’s SQD-Mini LED is not just a refinement of Mini LED; it’s a full-stack rethinking designed to rival OLED in color precision while surpassing it in brightness and durability.
