China Education Equipment Purchasing Network News: Projectors have become an indispensable teaching tool in the classroom, and the government's investment in education is also gradually increasing. As the education industry, which occupies nearly half of the market share, it must be most manufacturers A piece of realm that is ecstatic. With the development of new technologies in the projector industry in the past two years, short-focus, interactive, dustproof and other technologies have become the new mainstream of the market. What will be the future development trend of the education projection market?
"Zero focal length" projector products continue to climb
Since the advent of application solutions for short-throw projectors and electronic whiteboards, it has brought revolutionary application changes to multimedia education. Education users have been unanimously recognized for the perfect combination of the two, which has greatly promoted the development of short-throw projectors. In particular, the education market occupies a 40% share, allowing various projection "princes" to fight this market with short-throw projectors.
The reason why short-throw projectors are so popular is that because of their small distance requirements, they often only need a projection distance of tens of centimeters, which can project a larger picture in a shorter distance. The short-throw projector is also very convenient when it is installed. It only needs to be placed in front of the projection screen. Compared with the conventional projector that can only be installed in the middle of the roof, it has more advantages of space saving and convenient installation. In addition to the short-focus function, it can effectively avoid the problems encountered by traditional projectors, reduce the probability of light being blocked, so that teachers do not need to lecture under dazzling light and improve the quality of teaching.
Since last year, short-throw projectors have grown explosively. Almost all manufacturers have expanded their existing short-throw projector product lines on a large scale. From first-tier major brands to emerging brands, there are generally at least four to five short-throw projectors. There are nearly ten products with the most products. New short-focus products from manufacturers cover many market segments such as Full HD and network projection. The projection ratio is getting shorter and shorter.
For example, BenQ launched an ultra-short throw projector with a projection ratio of only 0.3 last year, which can project a huge 80-inch screen at only 15 cm from the wall. To this year, Acer's first newly launched "0" distance projector can project a 70-inch screen on the wall, while Mitsubishi's recently launched direct projection ultra-short throw projector has a projection ratio of one to one, the shortest is only 0.375. In addition to the products already launched above, ViewSonic also said that it will also focus on playing the "short-focus" brand in 2011 and launch it as a series of short-focus models, with a projection ratio covering the four specifications of 0.3, 0.6, 0.68 and 0.9, which will form The most complete short throw lineup of all brands in the market.
With the continuous development of modern multimedia teaching technology, having healthy teaching has become a major trend in the future education industry. In the past, most classrooms used ceiling-mounted front projection. The projector with a longer focal length is farther away from the screen. When explaining, teachers will inevitably stand between the projection screen and the projector and face the light bulb. Even if they stand on the side, the light bulb The resulting glare, strong difference between light and dark also exist. Therefore, when the speaker demonstrates in the middle, his eyes are easily stimulated by strong light and affect his health.
At present, short-focus projection products on the market can project a 100-inch or larger picture within a distance of about 1.8 meters. Teachers can stand outside the projection range to explain, greatly reducing the chance of facing the bulb, not only effectively solving The problem of shadow caused by the body blocking the projection light is protected, and the teacher's visual health is protected. Judging from the new products of ultra-short throw projectors introduced by many manufacturers, there will be more and more projectors with a "0" distance, which will become an inevitable development trend in the future.
Highlighted projectors are sought after by educational users
In recent years, with the continuous deepening of projection applications, engineering projectors have begun to appear more and more in large-scale ladder classrooms, and high-brightness engineering projectors have become ideal choices for large-scale ladder classrooms, lecture halls and other places . In addition to the application of highlight engineering projectors, the popular education projectors with highlights have gradually become popular in the education market.
In fact, when purchasing an educational projector, the brightness index has always become a more important one of the performance parameters, and it is also the user's most concerned. However, the brightness index is not as important as the user thinks, and the choice of projector should still be based on demand. However, high-brightness projectors often have obvious advantages in situations with strong ambient light, so for many large classrooms and stairs In classrooms and other places, it is still necessary to choose a product with higher brightness.
With the incidents affecting the eyesight of the projector last year, after being reported by many media, the brightness of the projector has once again been concerned by education users. According to a reporter ’s investigation, since most of the school ’s projectors are placed at the far left corner of the blackboard, they are diagonal to the back door of the classroom. The students sitting in the front are relatively clear. It is difficult to see clearly when the light is strong. To avoid reflections, some classrooms are equipped with curtains, but not all classrooms are equipped with blackout curtains. In this way, the students sitting in the back row cannot see the projection content clearly, and in the long run, the eyesight of the students is hurt.
Since last year, the brightness value of new projectors launched by various manufacturers has been greatly improved compared with the past, and many newly launched projection products are advertised as bright. Although there is currently no strict definition on whether to highlight, but generally speaking, the brightness value above 2500 lumens can be called highlight projection. For an ordinary middle school classroom of 60-80 square meters, without shading, the higher brightness and resolution can be easily handled during projection. In this way, the teaching quality in the classroom is significantly improved At the same time, it effectively protects the eye health of students.
The analysis believes that the pictures, videos, audio and video, and text projected by the bright projector provide students with a vivid, vivid, and clear visual image, which makes it easier for students to concentrate on the experience, and the key content is also easier to master. With the gradual popularity of high-brightness projectors in the education market in recent years, coupled with the continuous emergence of high-brightness projector products, the brightness of educational projector products will also attract new heights, and projectors with high-brightness products will also Will be the focus of future education users.
Ultra-short throw projection with whiteboard application becomes the future trend
With the acceleration and deepening of the new curriculum reform and educational informatization construction, the traditional multimedia electronic classroom with projection screen as the display terminal is being replaced by a more interactive interactive whiteboard. Successful cases of receiving good teaching effects in the use of interactive electronic whiteboards are constantly emerging. The new ultra-short throw projectors with electronic whiteboards have also won the favor of many consumers with their respective advantages. Especially in the education industry, the combination of projectors and electronic whiteboards and other teaching tools has brought modern education work. A brand new situation.
The interactive electronic whiteboard is fully equipped with a multimedia teaching application system composed of a short-throw projector. It has become the trend of multimedia development of global teaching activities. To enable the interactive whiteboard to play the best teaching effect, it can avoid hurting the eyes of the teacher and reducing shadowing. The super short-throw projector for eye protection of the projected picture becomes the best combination. Using short-throw projectors can effectively solve these problems encountered by teachers.
Since last year, judging from the information on multiple projector channels, almost all of Banbantong ’s projector procurement projects around the world are written in black and white, and the overall plan requirements for short-throw projectors and whiteboards are written in the bid. The demand for short-focus in the education industry is likely to reach a growth rate of about 10 times compared to previous years.
In such a good situation, of course, all manufacturers have also seen the future market prospects, and have begun to enter this subdivided field, such as Acer, ACTO, Mitsubishi, China Optics, ViewSonic and so on. New short-focus products are constantly emerging, and the technology is also gradually becoming mature. In particular, the projection ratio is shorter than one, so that the projector can project a large screen of more than 80 inches when it is close to the electronic whiteboard, making the presentation more complete and the communication smoother.
However, with the current trend of homogenization of projector products becoming more and more obvious, short-throw projectors are also unable to escape this disaster. In the past, the price competition and the advantages of product performance are no longer a buying point. At present, most of the manufacturers' customers are mainly in the education industry, which requires the manufacturers to bring something different from other manufacturers, such as the sale of short-throw projectors bundled with electronic whiteboards, so that education is more acceptable when purchasing It will also be a new trend in the future.
The appearance of a short-throw projector with an electronic whiteboard has greatly improved the existing teaching methods. During use, teachers will not be exposed to light sources and will not cause shadows to affect the viewing effect. It has great advantages over traditional products. In the future, short-throw projectors and electronic whiteboards will continue to grow, becoming a major trend in the education industry.
