China Education Equipment Purchasing News: With the continuous development of informatization education, flat teaching has already shown many disadvantages, such as too slow to update and stiff content, etc., and it is increasingly unsuitable for the development of new teaching. 3D projection teaching is currently becoming a new development trend. As the industry-leading Texas Instruments DLP, with its innovative technology, it has successfully brought Hollywood movie-like 3D effects into the classroom, creatively enabling schools to achieve immersion through affordable stand-alone 3D projectors. Teaching, which brings students a more real and dynamic learning environment, which greatly mobilizes students' enthusiasm for learning and greatly improves their academic performance. In addition, a survey conducted by JTM Concept on more than 1,000 students showed that the average test score of students in the class where DLP 3D technology is deployed has increased by more than 35%.
So how to equip the latest 3D technology teaching? Based on a 50 square meter classroom, the brightness of the projector should not be too low, but the brightness is too high and it is a waste, and it will cause eye damage, so usually come It is more appropriate to choose a projector of about 3000 lumens in a 50 square meter classroom. However, in order to avoid the light interference caused by the traditional projector and the series of problems such as the teacher blocking the picture, a 3D projector with ultra short throw function is no longer suitable. With it, coupled with 3D glasses and 3D teaching resources, a complete set of 3D teaching programs will be realized.
With these needs, I have locked a more suitable model among many projector products-this is the Acer U5200 reflective ultra-short throw projector, which distinguishes traditional projectors from the most commendable, except for the 3D function In addition, it has the ability to project a 77-inch screen at a distance of 13 centimeters, which is not possible with traditional projectors and short-throw projectors.
Acer U5200 Ultra Short Throw Projector
Acer U5200 uses the latest DLP display technology from Texas Instruments, with 2500 lumens brightness, 4200: 1 contrast ratio and XGA (1024 × 768) resolution. It uses reflective short-focus technology, making it free to place, making its application more flexible, while being able to adapt to more environments.
Acer U5200 ultra-short-throw projector uses TI's 3D teaching technology, combined with 3D educational teaching resources, can achieve vivid 3D teaching functions, make the teaching process more intuitive, vivid and interesting, and fully demonstrate the essence of teachers' classroom teaching , Efficient and able to focus on students' attention, and make the understanding of knowledge more profound, to achieve the "deep and clear" and "lively" teaching effect. Especially in the case of classrooms around 50 square meters, the U5200 ultra-short throw projector is more suitable for such applications.
In addition, the Acer U5200 also has the advantage of supporting USB. Teachers can project files in the format of PtG, JPEG, and BMP through USB storage devices. Both teaching reports and materials can be easily projected, which greatly facilitates teachers ’lesson preparation. jobs.
Acer U5200 also added EcoProjection technology to reduce standby power consumption to one watt, enabling environmentally friendly energy management. The life of the projection lamp is long, which reduces the cost of lamp replacement and ensures the reliable performance of the projector after long-term use; ECO mode can extend the life of the lamp and reduce noise and power consumption. This projector has built-in Auto ECO function, if there is no signal input within 5 minutes, it will automatically enter ECO mode, thereby reducing power consumption by up to 20%.
Acer U5200 projector is also equipped with network interface and network management tools, which can control and manage the projector through the network, so as to understand the running status of the projector in real time, and realize various operations such as remote power on and off, switch input source and so on. At the same time, the machine also added a USB playback function, which means that users can directly demonstrate the content stored in the USB storage, increasing the portability of the projector.
In recent years, short-throw has become the most popular projection technology, and projection manufacturers have spared no effort to launch various short-throw products. This has directly caused the phenomenon of serious homogenization of short-throw products. In order to avoid this phenomenon What happened to Acer, Acer worked hard on the product, launched a highly competitive U5200 product, which will undoubtedly bring a new experience to the short-focus market.
