SID2026 TCL Huaxing world's first ultra-high transfer 50 ARR display technology debut

Under the wave of high-resolution, high-brush, and low-power consumption display technology, TCL CSOT's ultra-high-speed 50 oxide technology breaks the bottleneck of traditional backplane technology and combines the advantages of high performance and low cost.

According to reports, the world's first matrix zoned and frequency-zoned Oxide laptop screen equipped with this technology uses ARR (AI Refresh Rate) multi-zone dynamic frequency conversion technology to achieve an ultra-low refresh rate of 0.01Hz and reduce power consumption by 50%. It provides a high-quality, low-energy consumption core solution for AI PCs and next-generation display devices, leading LCD technology into a new generation.

▋ Demand iteration drives technology innovation LCD backplane opens a new track for performance improvement

For a long time, the performance improvement of LCD display technology has always been closely related to the evolution of backplane driver devices. As the industry's requirements for display experience continue to upgrade, traditional backplane solutions are no longer able to fully meet the comprehensive needs of multiple scenarios:

Amorphous silicon (a-Si) TFT: The process is mature and stable, but the mobility level is limited. There are performance bottlenecks in high-end application scenarios such as high resolution and high refresh rate. At the same time, static power control is difficult to meet the higher standards of current low-power designs.

Low-temperature polysilicon (LTPS) TFT: has high mobility and can support high-performance displays. However, the process is complex, the cost is high, and the leakage current control capability is limited. It is difficult to meet the low frequency and low power consumption requirements, and cannot support the G8.5+ large-generation line panel.

Traditional oxide TFT: Excellent performance in low off-state current characteristics, but there is still room for improvement in mobility. It is difficult to achieve synergistic optimization of high brush and high resolution at the same time, and cannot fully unleash the performance potential of LCD technology.

As the consumer market's image quality requirements for laptops and monitors continue to increase, and the professional market's performance demands for VR/AR, medical display and other equipment continue to grow, the industry urgently needs a new backplane technology that combines high mobility, low power consumption, high reliability and low cost to break through the performance ceiling of LCD displays. It is against this background that TCL CSOT's ultra-high-speed 50 oxide technology came into being. Through the substantial increase in mobility, real thousand-brush ultra-high frequency driving can be achieved, device miniaturization improves penetration and achieves extremely narrow borders, while creating key conditions for the implementation of single IC integration solutions.

▋ Underlying technology leads breakthroughs, UHMW 50 achieves a performance leap

TCL CSOT has deeply researched the underlying core technology, and jointly launched the independently developed UHMW 50 oxide technology with Professor Hideo Hosono. Through three core technology breakthroughs, it has built a complete technological closed loop of high-performance oxide TFT.

■ Process system reconstruction: Build an extremely uniform oxide semiconductor system

In order to achieve the ultimate uniformity and density of oxide semiconductor films, TCL Huaxing took the lead in breaking through the traditional process path and introducing industry-leading linked rotating target sputtering film forming technology. The superimposed composite stack design suppresses film defects, enhances the corrosion resistance of drug-resistant liquids, greatly improves device uniformity and stability, and lays a solid foundation for high-performance oxide TFTs. At the same time, a composite repair process is innovatively used to improve the interface, completely solving the device and process problems caused by the high In content of high-migration materials, and greatly improving the material mobility.

■ Core device challenges: Precise control of the hydrogen-oxygen level of the insulating layer to overcome the stability problem of ultra-high mobility devices

Ultra-high mobility oxide TFT devices are highly sensitive to environmental and process variables such as water vapor, hydrogen, and oxygen. The loss of hydrogen and oxygen components in the insulating layer will directly lead to device performance degradation. Based on the mechanism research and process accumulation of oxide devices, TCL Huaxing has constructed a precise hydrogen and oxygen level control system for the front and rear channel insulating layers. Through precise leveling of hydrogen and oxygen components, low-defect interface construction and high-density barrier layer preparation, it can simultaneously improve device leakage suppression, defect state control and environmental barrier capabilities, ensuring the stable operation of the device under high mobility.

■ Full-link design optimization: Circuit architecture and TFT design innovations unleash the performance potential of ultra-high-speed 50 oxide

As the mobility of oxide semiconductors increases, the gate's ability to regulate the channel is relatively weakened, and devices are prone to threshold voltage drift problems. At the same time, the output current of high-mobility devices has increased significantly, and the intrinsic thermal conductivity of oxide materials is low, resulting in intensified self-heating effects of devices, restricting performance and reliability. Through the development of new GOA circuit architecture, TFT device structure optimization and heat dissipation enhancement design, TCL Huaxing has achieved a deep adaptation of the circuit architecture and ultra-high mobility oxide device characteristics, fully unleashed the performance potential of high-mobility materials, and achieved the dual goals of product specification upgrade and high reliability.

Currently, TCL Huaxing has achieved breakthrough results in key device characteristics: the electron mobility of ultra-high mobility oxide devices can reach 50cm²/V·s, and its stress stability is equivalent to that of mass-produced oxides. It also has excellent withstand voltage characteristics and reliability, and has shown clear prospects for mass production. TCL Huaxing plans to achieve a breakthrough in mass production of this technology within 2026, thus establishing its industry-leading position in the field of oxide display technology.

▋ TCL CSOT ARR technology makes a grand debut, and the screen enters the era of scene intelligence

TCL CSOT's Adaptive Partition Refresh Rate (ARR) technology adopts ultra-high-resolution 50 technology, combined with innovative breakthroughs in panel design, materials, and driving algorithms, to achieve a leap in product performance and open up new development prospects for notebook displays.

Panel architecture + driver innovation: Build a new form of horizontal + vertical two-dimensional matrix partition driver

The innovative use of new GOA design and circuit design breaks through traditional display limitations and achieves flexible partition control. In the horizontal direction, "rows" are used as the smallest physical partitions to achieve precise frequency control at the pixel level; in the vertical direction, COG IC is used to complete the hardware partitioning, and then through precise control of software algorithms, software and hardware collaborate to achieve flexible partitioning in the vertical direction. The refresh rate of any area of the screen is truly independently controllable. High refresh and low refresh areas can be intelligently divided according to the screen content to achieve differentiated refresh in multiple areas.

■ Ultra-high-frequency 50 oxide technology blessing: enabling stable display of extreme high and low frequencies from 0.01 to 120Hz

Based on ultra-high-frequency 50 oxide technology, it achieves extreme high and low frequency stable display capabilities of 0.01~120Hz. It effectively overcomes the difficulties of traditional screens such as uneven brightness and screen flickering at low frequencies, and ensures that the screen brightness is highly uniform when switching between high and low brushes. Whether it is a 120Hz high brush dynamic picture or an ultra-low brush static picture, it can present stable and delicate visual effects.

■ AI empowerment: AI scene recognition + AI PQ image quality dual-dimensional upgrade

Relying on AI intelligent empowerment, it is equipped with dual algorithm capabilities of AI scene recognition and AI PQ image quality compensation.

AI scene recognition can intelligently identify dynamic and static content on the screen, accurately divide the attributes of picture areas, and intelligently schedule high and low refresh areas on demand; the dynamic area maintains a silky and smooth 120Hz high refresh rate, and the static document area can drop to an ultra-low refresh rate of 0.01Hz, significantly reducing screen power consumption without sacrificing the look and feel or flickering.

The AI PQ image quality compensation algorithm intelligently adjusts brightness according to different refresh rate partitions to ensure visual differences between high and low frequency areas; it also dynamically adjusts color gamut, contrast, and brightness according to different content scenes to provide users with a high-quality display experience.
