According to reports, the newly upgraded NEC business education projector new product New Venus series, covering 17 models such as CA4300U, CA4300W, CA4400X, CR2300U, CR2300W, CR2400X, etc., has been improved in terms of brightness, resolution, and contrast. . Its brightness covers from 3400 lumens to 4700 lumens, bringing a richer and more complete product selection to business and education customers who have diversified and customized display needs. New product CA4300U (4200 lumens, 1920*1200 full HD resolution) New product CA4300U (4200 lumens, 1920*1200 full HD resolution) New product CA4400X (4700 lumens, 1024*768 resolution) New product CA4400X (4700 lumens, 1024*768 resolution) While the brightness is upgraded, the new product has also improved in resolution, with three mainstream resolutions of WUXGA, WXGA, and XGA. Among them, CA4300W not only supports WXGA resolution, but also has a brightness of up to 4400 lumens. In addition, the full range of new products also uses 3LCD projection technology, with a high contrast ratio of 16000:1, so that the dark details can also be well presented, and the screen display is more gorgeous and rich. Compared with the 5000-6000 hours service life of ordinary lamp projectors, the new Venus series adopts a newly upgraded lamp with a lamp life of up to 20,000 hours (ECO mode). The new products all use the latest inorganic liquid crystal panels. Compared with organic materials, inorganic materials have high light resistance and better heat resistance, are not easy to deform, and are more durable. At the same time, the new Venus series also follows the NEC conflict air cooling technology, abandoning the traditional projector’s cooling method of single-sided LCD panel air intake and single-sided air outlet, and adopts both sides to enter the air at the same time, and the two winds The central position of the LCD panel meets and pushes each other, resulting in a spiral airflow, which makes the LCD panel heat dissipation more uniform and efficient; and the new “conflict air cooling system” can greatly extend the life of the LCD panel and the polarizer, and the fan noise is also reduced. Improved. The new Venus series has a rich throw ratio and supports up to 1.7x zoom lens. In addition to supporting horizontal, vertical, trapezoidal correction, 4-corner correction, and curved surface correction, the new product also adds 6-corner correction, multi-point keystone correction 17*11 points (HD model), so that it can be used for multiple single-machine applications or multi-machine integration. Applications are more convenient and flexible, providing strong compatibility for complex and diverse business and education scenarios. In addition, the settings of application software such as MultiPresenter and NaViSet2 intelligent network management system also make the operation of the new Venus series more intelligent. MultiPresenter integrates wireless projection, multi-screen display, web page sharing, projection control and other functions; in addition, the NaViSet2 intelligent network management system also realizes the intelligent network management and control of multiple devices, making customers’ operations more convenient and intelligent.

According to the Telecoms , China’s National Intellectual Property Administration (CNIPA) said that the country is leading the world in the number of patents related to 6G network technology.

Specifically, China accounts for 35% of about 38,000 6G-related patents in the world, or 13,449 patents. In second place is the US with the number of patents accounting for 18%. The 6G network is expected to be 100 times faster than 5G. Photo: PhoneArena. While the US and Europe have launched 6G research projects, strengthening cooperation to ensure benefits, CNIPA said that China has “taken advantage of the technology from 5G networks to continue to be at the forefront”. According to CNIPA, the country of billions should cooperate with a number of Japanese and Korean companies such as NEC, Samsung, and Mitsubishi to “reduce dependence on American and European technology” in some important areas of the 6G network. . Although China leads the world in 6G patents, only one Chinese company makes the list of the top 10 6G enterprises in the world. According to the PhoneArena , the three names holding the most 6G patents include NEC, Daewoo Communications and Mitsubishi. In the areas of artificial intelligence (AI) and terahertz of 6G, China accounts for 75% and 40% of patents globally, respectively. Regarding terahertz in 6G networks, the two largest patent holders are the University of Electronic Science and Technology of China, and China University of Metrology. Although it will take many years to perfect, 6G is expected to bring speeds of terabits, 100 times faster than 5G networks, wide coverage from underwater to space. Some applications of 6G such as immersive augmented reality environment, high-fidelity 3D image display. The speed of 6G brings benefits in many future fields, not only for users but also in the military sector, which is why industrialized countries are vying for the top spot in the research race. 6G. In November 2020, Google and Apple joined “The next G Alliance” (The next G Alliance) with the goal of making the US lead the world in the 6G race, reinforcing the long-term development of the company. 5G network. In February, Apple recruited a number of positions specifically related to 6G, the main work included “researching and designing next-generation wireless communication systems (6G) for wireless networks”, “participating in industry, academic forum on 6G”. In February 2019, former US President Donald Trump also mentioned 6G. “I want to have 5G, even 6G in the US as soon as possible. It’s stronger, faster and smarter than today’s standards. American companies have to work if they don’t want to be left behind,” Trump said. on Twitter. China launches first 6G satellite tinh This 6G satellite will be used to test systems for smart cities, environmental protection, disaster prevention and mitigation.
