With the rise of Mini/Micro LED technology, the performance of LED displays continues to improve, and display specifications are gradually developing towards small and ultra small pitch. At the same time, virtual filming (xR), cinema display AR/VR、 The rapid emergence of emerging applications such as naked eye 3D and creative displays has put higher demands on display control systems.
Recently, at the 2024 TrendForce Self luminous Display Industry Seminar, the director of the Nova Nebula Academia Sinica laboratory delved into the technical challenges and development space of display control systems in the context of the rise of MLED applications.
Nova Nebula launches multiple innovative control system technologies
In modern application scenarios, control systems not only need to solve hardware and technical problems, but also need to pay attention to end-user needs, daily maintenance, and industry pain points. Solving these problems is the key to promoting the expansion of the MLED market. To this end, Nova Nebula has developed multiple innovative technologies such as ultra large load controllers, multiple backup technologies, fault monitoring and warning technologies, which have effectively promoted the development of the industry.
Taking the Pangu Grand View Large Screen Project at the 2008 Beijing Olympics as an example, this project marked a milestone in the application of large-scale splicing screen displays. In such major projects, the control system must have high capacity, zero error, and foresight to ensure project success. However, there are still many technical bottlenecks that need to be overcome in simplifying operations and improving stability for controllers that can support extremely large loads.
Backup technology is also crucial in critical application scenarios. For example, during important moments such as National Day parades and live broadcasts of sports events, the malfunction of LED screens not only affects the success or failure of a single project, but may also damage the brand image of the entire market. Therefore, technological breakthroughs in redundant backup, link backup, and multi device backup are crucial for ensuring the stability and reliability of the system at critical moments.
In addition, fault monitoring and warning technology also plays an important role. This technology can identify network cable errors and light board defects before faults occur, and accurately locate faulty equipment such as receiving cards, controllers, or ports for timely maintenance. This technology is particularly important in places such as stages, landmark scenes, and long-term unmanned highway display screens. Through cloud based warning, the system can remotely monitor and promptly notify maintenance personnel for repairs, improving the reliability and maintenance efficiency of the system.
Control system helps expand the market for new MLED applications
With the continuous penetration of MLED technology in xR virtual shooting, cinema screens, in car, TV and other application fields, it is driving users to continuously upgrade their new display experience, and the display control system has also become an amplifier of new display value.
In the field of virtual shooting, the control system requires higher display and shooting system synchronization technology. Due to the display effect being directly captured by the camera, high-precision image quality adjustment must be achieved on different camera systems to ensure that the final image meets the needs of the human eye. At the same time, breakthrough demands have also been put forward in areas such as high image quality and color perception processing, fast screen matching, and scene switching.
In terms of cinemas and high-end professional displays, LED display control systems face technological bottlenecks such as image quality, color, and HDR, especially in meeting the new version of DCI certification standards. In addition, the control system also needs to support integrated media playback and security protection, providing standardized and regulated solutions for large-scale market applications.
In the field of in vehicle displays, control systems also face multiple challenges, mainly focusing on system startup speed, integration between the vehicle and cabin domains, image quality and calibration, as well as requirements for vehicle level management systems. Nova Nebula is striving to meet and has already begun to implement the requirements of the corresponding quality management system and research and development management system. At present, there are customers who have cooperated with the company in the fields of automotive products such as headlights, inner frame control display media, and taillights, and have successfully released related products.
In the field of LED all-in-one machines and consumer TV, the control system needs to meet the requirements of small size, low power consumption, and pleasing image quality. Consumer grade displays emphasize catering to the aesthetic preferences of users in different regions, thus having higher demands in terms of image quality enhancement and style algorithms. Integrated and chip based control systems also contribute to improving cost-effectiveness and promoting the popularity of MLED in the consumer market.
brief summary
With years of technical accumulation in the field of display control systems, Nova Nebula has developed a series of advanced display control system related technologies, and has helped create multiple milestone projects including the first large display screen in China - the main background screen for the Beijing Olympics. Based on the above technological foundation, Nova Nebula is currently focusing on the research and development of five core display technologies, including grayscale resolution, temporal resolution, spatial resolution, dynamic range, and color gamut range, continuously innovating to enhance the value of display screens.
With the rise of emerging applications of MLED, display control systems have ushered in various key development opportunities. Nova Nebula will continue to promote technological innovation, further enhance the overall value of display screens, and meet the growing market demand. At the same time, the company will strengthen cooperation with industry partners and work together to expand the prospects of the MLED market.
