CINNO Research data shows that in 2024, the Chinese Mini LED TV sales will soar nearly 7 times year-on-year, with the penetration rate skyrocketing from under 5% at the beginning of the year to 18% by the end. The new round of national subsidy policies is expected to push the penetration rate to nearly 40% by 2025.
In response to the explosion of the MLED technology-driven trillion-dollar market, upstream display driver chip companies are already positioning strategically. For instance, New Vision Microelectronics recently invested ¥120 million (~$16.3 million) to set up a new display industry merger and acquisition fund, targeting key technologies such as chip design and mass transfer. The iteration speed of new display technologies is far surpassing traditional cycles, and driver chips must break through the limits of accuracy, power consumption, and cost to support full-scale innovation across sectors, from consumer electronics to automotive displays.
I. Technology-Driven: MLED’s High Precision Requirements Force Chip Architecture Innovation
Traditional display driver chips have long followed a “integrated” versus “separated” technological division of labor. Integrated chips, represented by AMOLED, support flexible display requirements for smart wearables. For example, the Apple Watch Ultra uses a single chip to integrate source drive and timing control functions for low power consumption and miniaturization. On the other hand, separated chips are commonly used in large-size scenarios with multi-chip combinations, such as Samsung’s QD-OLED TV, which uses 16 driving chips to achieve million-level partitioned light control.
However, MLED technology imposes near-demanding requirements for precision, power consumption, and integration—especially for Micro LED. For instance, the pixel density can reach 1800 ppi (for AR/VR scenarios), far exceeding the 300 ppi of traditional LCD, forcing chip architecture to shift from “functional adaptation” to “performance reconstruction.”
In terms of technical breakthroughs, MLED‘s extreme demands on refresh rates and grayscale have led to the engineering application of hybrid drive technology. Traditional PWM dimming faces severe flickering issues at low grayscale levels, while TBSilicon’s Hybrid PWM+PAM scheme, which combines pulse-width modulation (PWM) and pulse-amplitude modulation (PAM), achieves a 1200Hz refresh rate at 1 nit brightness, with dynamic contrast rising to 1,000,000:1. This resolves the screen tearing issue in virtual filming, where synchronization between camera and screen is critical.
This breakthrough by TBSilicon was validated at ISE 2025, where its 24-bit grayscale gradient image used pixel-by-pixel color temperature adjustment, achieving ΔE < 0.5 for the dark regions of starry sky scenes, reaching the level of professional monitors. Meanwhile, Sunmoon Microelectronics‘ SM6016N chip, utilizing ASIC architecture, compresses data processing time to the microsecond level and supports 4096 partitioned light control, significantly reducing timing delays compared to traditional solutions.
Another key technological challenge is mass transfer and chip integration. The core obstacle to Micro LED mass production lies in the transfer yield and driving integration. Traditional elastic stamp technology yields only 70%, while Aledia’s silicon-based nanowire technology increases the yield to 95% by vertically integrating the driving circuit.
The recently released LEKIN Semiconductor SiMiP (Silicon-based GaN Single-Chip Full-Color Micro-LED) is a disruptive innovation. This technology integrates the red, green, and blue pixels into a single chip, bypassing the mass transfer challenge and improving the yield by more than 30% while reducing production costs by 40%. This offers a cost-effective solution for Micro LED direct-view large screens. This technological breakthrough complements the BOE’s glass-based MLED, which uses active AM drive technology to eliminate the scanning flicker issue in traditional PM drive, significantly improving the visual comfort of automotive HUDs (Head-Up Displays).
II. Market Expansion: Emerging Scenarios Fueling Explosive Demand for Chips
The wave of technological breakthroughs is driving the rapid expansion of MLED applications. As MLED technology rapidly penetrates the TV sector (with CINNO Research forecasting a 40% penetration rate for Mini LED TVs by 2025), its applications are accelerating into emerging fields like automotive displays, virtual filming, and AR/VR.
i. Automotive HUD: A Key Application Scenario for MLED
Automotive HUDs have become a major scene for MLED technology implementation. BOE’s LTPS P0.9 glass-based MLED product, using AM active drive technology, reduces power consumption by 40% while achieving flicker-free 7680Hz displays, making it suitable for automotive scenarios with strong light and vibration conditions. In 2024, the HUD penetration rate in Chinese passenger cars reached 14.3%, with vehicles priced over ¥300,000 ($41,000) having a penetration rate exceeding 36%. The driving chips need to meet the AEC-Q100 Grade 2 automotive-grade certification to maintain signal stability in extreme temperatures from -40°C to 105°C. For instance, NovaStar‘s MLED display ASIC chip, using 3D stacking technology, compresses signal transmission delay to 5ns and integrates redundant circuit designs.
ii. Virtual Filming: Meeting Demands for MLED Displays
In virtual filming, MLED displays face stringent requirements of 24-bit color depth, HDR 2000 nit brightness, and 7680Hz refresh rates. BOE’s solution showcased at ISE 2025 utilizes NovaStar‘s MLED high-speed interface chip, achieving 16-bit grayscale and 97% DCI-P3 color gamut, with synchronization errors controlled to under 0.1ms. This technology has been applied in the filming of The Wandering Earth 3, enhancing efficiency by three times and reducing scene switching time from hours to minutes compared to traditional green screen production.
iii. AR Glasses: Meeting Extreme Requirements for MLED Chips
AR glasses demand MLED chips with 1800 ppi pixel density and less than 1mm³ package volume. Leyard and Saiflus have jointly developed a monochrome MLED micro-display, integrating the driving circuit into the Micro LED wafer using silicon-based integration technology. The module thickness is reduced to 0.8mm, with power consumption of only 15mW, making it suitable for all-day wear. Market data shows that by 2025, the global MLED driver chip market for AR/VR is expected to reach $1.2 billion, with a compound annual growth rate of 67%, and AM MicroLED will account for over 80%.
Despite the strong demand from emerging scenarios, MLED driver chips still face the three major challenges of “performance – cost – yield”. In the automotive sector, LTPS glass-based MLED is 30% more expensive than traditional PCB solutions and must achieve scale cost reduction through 8-inch wafer mass production (with BOE’s Zhuhai production line already operational). In the AR/VR field, the yield for Micro LED mass transfer is only 70%, and Aledia’s silicon-based nanowire technology increases the yield to 95%, but the equipment investment increases by 2.5 times. In virtual filming, high-speed interface chips depend on sub-28nm processes, with a local production rate of less than 20%. The 14nm MLED control chip jointly developed by Huawei and NovaStar is expected to begin mass production in 2026.
III. Industrial Collaboration: Full-Link Integration Accelerates Chinese Substitution
When technological innovation resonates with market demand, deep collaboration across the industry chain becomes the key to victory. With companies like BOE, AMTC, and others completing full-link layouts from “chips – packaging – inspection“, MLED technology is moving from a display revolution to industrial ecosystem restructuring. The synergistic effects of the industry chain are becoming increasingly prominent in the commercialization process of MLED.
Chinese display companies are accelerating technology implementation through vertical integration. BOE has acquired HC SEMITEK to lay out Micro LED chips, and combined with NovaStar‘s Demura testing system, they have optimized the collaboration between driver chips and panel processes, reducing overall costs by 20%. AMTC‘s strategic cooperation with NovaStar focuses on MLED display control solutions and core integrated circuit development, promoting the mass application of testing equipment.
This full-link integration model has shown significant results in cost control. Some agencies predict that by 2025, China’s MLED driver chip production capacity will exceed 5000KK/month, with scale effects reducing the unit price from $0.8 to $0.4 per chip, providing critical support for the 40% penetration rate of Mini LED TVs. However, there are still concerns behind the technological leap. While silicon-based integration solutions offer excellent performance, their equipment investment is three times that of traditional solutions, and in the short term, they will still rely on policy subsidies and joint industrial investments.
Looking ahead, the competition for MLED driver chips will enter a three-dimensional game of “performance – cost – ecosystem.” In the short term, Hybrid drive technology and silicon-based integration solutions will dominate the high-end market, while glass substrates + AM driver technology will continue to make breakthroughs in the automotive, AR, and VR industries. Ultimately, MLED’s massive market potential can only be realized through deep collaboration across the entire industry chain, and the driver chip industry’s technological transformation will be a key step in accelerating the industry’s growth.
IV. Conclusion
The growth of the MLED market is reshaping the technological landscape of the display industry. Micro LED technologies are making significant strides in applications such as automotive displays, AR/VR devices, and virtual filming, all while creating an ecosystem that requires continuous innovation in chip architecture, manufacturing processes, and industrial cooperation. With the industry working toward scaling production and reducing costs, we are on the cusp of a display revolution that could drive trillions in market value.
