Micro LED Accelerates Penetration of Traditional Markets <br /> In recent years, LED display technology has continued to evolve from large-pitch outdoor displays to small-pitch indoor displays, with products gradually adapting to diverse user needs and widely covering indoor and outdoor application scenarios. In addition to traditional display technologies, direct-light emission technology has demonstrated enormous potential and is gradually moving towards micron-level Micro LED, driving the development of LED display products towards smaller pixel pitches and more diversified application scenarios.
According to TrendForce data, Micro LED technologies accounted for 20% of the market in 2023, and the market size is expected to reach 20 billion yuan by 2025, with a penetration rate exceeding 50%. Against the backdrop of intensifying domestic competition, new technologies such as COB and MiP are constantly emerging, providing key support for the steady increase in Micro LED market share and driving the development of this technology.
Micro LED has demonstrated broad market potential in multiple application scenarios. Taking conference rooms as an example, these scenarios offer moderate size but high demand, and Micro LED can replace traditional projectors and conference panels. In addition, Micro LED can also be applied to home theaters, lobbies, and other fields, boasting rich application prospects and strong future development potential.
Absen has developed 8 core capabilities for Micro LED . With the expansion of the Micro LED market, Absen is fully prepared, having formed 8 core capabilities covering testing and repair, chips, transfer and die bonding, packaging, driving, mechanical precision control, calibration, and control systems. These capabilities lay the foundation for achieving high contrast, wide viewing angle, wide color gamut, and uniform brightness and color of Micro LED displays.
Although Absen does not directly manufacture chips, it collaborates with industry partners to explore chip types and parameters that meet user needs. Secondly, die bonding and transfer technologies improve production efficiency and are key factors in the development of Micro LED. Packaging technology determines the product's reliability, stability, and the consistency of black ink, affecting the final display effect.
In terms of driving technology, Absen is gradually transitioning from traditional PM driving to PM+PAM and pure AM driving to improve display effects and reduce power consumption. Mechanical precision control plays a decisive role in the flatness of Micro LED products, directly affecting visual performance. Calibration technology is also crucial, as the uniformity of Micro LEDs can impact display quality.
Finally, control systems and testing and maintenance technologies ensure product stability and maintainability, supporting continuous technology optimization and application expansion. This strategic focus in these areas underpins Absen's competitive advantage in the Micro LED market.
Absen creates Micro LED display technology that is both black and bright.
The development of Micro LED technology is primarily driven by user demand. Users are constantly raising their requirements for display performance, especially in terms of clarity, contrast, color, and viewing angle. To further explore the ultra-high display potential of Micro LED, Absen has developed a "both black and bright" Micro LED display technology based on eight core capabilities, which is applied to the latest CL V3 and iCon series.
Absen's technical solution is based on groundbreaking parameters, combining world-class chips with HTB packaging technology to achieve a 99.3% black area ratio in LED displays, increasing the black field area by 70%. In this way, Absen can provide a purer black display effect, enhancing the contrast and visual depth of the image.
On the other hand, the product boasts a light transmittance exceeding 95% and a luminous efficiency exceeding 70%. Its ultra-high brightness and large black areas achieve a million-level contrast ratio, significantly enhancing display performance and revolutionizing traditional products. This product fully meets the market's demand for Micro LED displays with clear image quality, sharp contrast, wide viewing angles, vibrant colors, and uniform brightness.
In summary, Absen responds to users' high demands for Micro LED displays by improving core technologies such as black level ratio, light transmittance, and contrast ratio, providing the market with a clearer, brighter, and higher contrast display experience.
Absen will continue to drive innovation and development in Micro LED . Absen's foray into panel-based products began in 2016, with a commitment to continuous innovation and development of Micro LED technology. Since then, Absen has consistently launched new products. In 2018, it released its first-generation Micro LED product, subsequently introducing HDR technology. In 2021, the company launched its CL series of high-brightness products, further expanding its market applications.
In 2024, Absen launched FTB packaging and surface treatment technology, further improving display effects and achieving the technological advantages of "both black and bright" Micro LED displays. In addition, Absen also launched APMS power management technology to achieve energy saving and consumption reduction in Micro LED displays, providing end users with a comfortable and worry-free user experience.
Looking ahead, Absen will continue to deepen its research and development of Micro LED technology, focusing on tackling core technologies and driving breakthroughs in key areas. Simultaneously, the company will work closely with strategic partners to integrate upstream and downstream resources across the industry chain, proactively address future market demands and technological challenges, promote innovative development in the LED display industry, and lead the industry to new heights.
