Changhong leads the launch of national high-brightness LED projection display technology project

At the meeting, Pan Xiaoyong, member of the Party Committee and Deputy General Manager of Changhong Holding Group, said that Changhong will fully support the research and development work of this project, ensure project needs in terms of human and material resources, and work with all participating units to overcome difficulties and complete the project research and development plan with high quality under the guidance of the Ministry of Science and Technology and experts.

In recent years, the projection display market has been in a continuous growth trend. However, current projection products all use the passive light-emitting principle, which has problems such as low contrast, poor dynamic clarity, and complex optical paths. Moreover, the core components of projection display products—light sources and light modulator chips—are monopolized by a few companies in Japan and the United States. The purchase price is high and technology development is slow, which seriously restricts the development of the projection display industry.

It is understood that through the implementation of this project, the industry chain is expected to fundamentally solve the above problems, innovate the principles of projection display, master core technologies, and build an independent and controllable supply chain. Its important strategic significance and value include the following parts: building an independent projection industry chain, reconstructing a new platform, breaking foreign monopoly, developing global advantageous industries, and expanding overseas markets; promoting the transformation of projection display technology and promoting To develop the industry by leaps and bounds, create a larger market space for the projection industry, further highlight the differentiated advantages of the projection display and flat panel display industries, and enable the projection display industry to quickly integrate into mainstream display technology and develop simultaneously; while improving the performance of projection display while simplifying the system architecture, the main technology can cover all current projection display products, allowing domestic projection display products to lead the development and take the lead in international competition.
