Changhong: Big Screen Education Chooses Laser Display Smart Terminal

Recently, the “big” trend has not only become a standard for home users to purchase televisions, but also has had an important influence in the field of education informatization.

Compared with traditional projectors or TVs as teaching display devices, laser display terminals have the advantages of near-projection distance, convenient installation methods, more excellent display performance, and green environmental protection, becoming more and more intelligent educational display terminal upgrades in schools. The preferred alternative.

Performance Revolution Education upgrades new trend

Demand stimulates technological innovation, and technological innovation in turn drives the continuous improvement of demand. This is also very evident in the process of education informatization. When ordinary televisions and projectors that have been used for many years are covered with dust and are difficult to meet the needs of modern teaching, users and suppliers of the educational information industry are constantly looking for breakthroughs and innovations.

This latest "revolution" falls on the laser display device, and behind this is the industry's big coffee - Changhong's thick and thin hair. On December 21, 2016, Changhong brought a New Year's gift to the industry. Changhong CHiQ laser product P5 series is used in the field of business education and equipped with a 120-inch wide-angle eye screen, priced at 29,997 yuan.

Changhong CHiQ laser cinema P5 series uses global high-quality parts materials, imported ultra-short focal-inverse lens, display size is flexible; built-in electric focusing function, easy to achieve 80-150 inch precision focusing, focusing, sharpness, uniformity industry Leading; adopting TI's DLP digital optical imaging technology, the imaging has a spatial characteristic and a strong sense of screen; imported Nichia light source, high brightness and a long life of 25,000 hours.

Changhong's technical team based on the development of more efficient laser light machine, using the dynamic elimination of speckle technology and telecentric light system, to achieve a major breakthrough in overall performance. Subvert the industry's existing blue laser excitation phosphor technology program, the first proposed integrated single-axis two-wheel color system technology program, through the remote rotation of the fluorescence device and the filter device, to achieve a blue and yellow green light sharing the same optical technology, great The problem is that the size of the light engine increases due to the optical path turning of the transflective fluorescent wheel is reduced, and the problem of the unsynchronized color system introduced in the double-wheel rotation is solved; the ultrashort-distance Galileo optical telephoto system, the wide-angle laser are innovated. The light-harvesting technology and highly integrated light-sharing and light-sharing technology have formed a great lead in technology, greatly simplifying the optical path, effectively improving optical efficiency and reducing power consumption. The light efficiency of the CHiQ laser theater lighter reaches 31 lm/W, while the current industry average is only 18 lm/W.

Ring protection eye cares for students' physical and mental health

Changhong CHiQ laser P5 series has a more relaxed viewing distance than LCD TVs (3.2-3.5 meters for laser theaters and 6 meters for LCD TVs). At the same time, laser cinema uses reflective display technology. Compared with the direct light of liquid crystals, the reflected light is softer and the healthiest display mode. Green and eye protection make watching TV the same as reading a book.

Chen Ning, general manager of Changhong Laser Display Technology Co., Ltd., said that laser display technology has the advantages of high brightness, long life, wide color gamut, low power consumption, and can achieve large size display.

Industry experts commented that Changhong's CHiQ laser cinema has brought educational display technology to a new stage of greater, more energy-efficient and greener environmental protection.

Brand strength promotes rapid development of education

Changhong is one of the earliest home appliances companies that independently researched and developed projection products. With cutting-edge R&D equipment and first-rate R&D team, Changhong has become a first-class laser display product R&D and manufacturing enterprise in the laser display field for over a decade of technology accumulation. With the ability to independently design, independently produce laser light machines, optical screens, and laser hosts, it is completely autonomous in its operations from R&D and design to complete production and manufacturing, ensuring product quality, delivery, and service. At present, Changhong has launched home laser theaters, laser education projectors, laser business projectors and laser engineering projection products and other products.

“From black-and-white TV, color TV, flat panel TV, projection display, and laser display, Changhong has experienced the precipitation of various industries in the display industry. In the face of the future trend of super-large display, Changhong has once again succeeded in early layout and lead.” Deputy Secretary-General, China Electronics Chamber of Commerce Lu edge wave gave a high evaluation.
