DHN Laser projectors promote the transformation of traditional teaching mo

As multimedia technology enters the school, multimedia tools such as computers
and projectors are increasingly becoming indispensable equipment in classroom
teaching. However, the lack of operation and function of these devices is also
increasingly obvious, mainly in the following: content display is dull, can not
mobilize the enthusiasm of teachers and the enthusiasm of students to learn;
lack of interaction and communication between teachers and students, can not
receive the ideal Teaching effect. As a result, many schools have begun to
replace teaching equipment, and the application of interactive large-screen
projection has brought new inspiration to the transformation of traditional
For some problems in the traditional classroom, let's take a look at how the
DHN laser projector DM907 is playing its functional role in the education
Question 1: After writing on the whiteboard, it is easy to leave a mark, which
is not clean and affects the next use effect.
Solution: DM907 uses touch as a human-computer interaction method. The hardware
uses a high-precision recognition infrared camera. The infrared pen can
smoothly and accurately perform writing, drawing and touch operations on the
curtain wall. It can replace the current interactive mode of electronic
whiteboard + projection on the market, providing a more convenient solution for
education and teaching.
Question 2: In order to ensure the clarity of the projected picture, the
traditional classroom needs to close the doors and windows, pull the curtains,
and turn off the front lights, but the darkness in the room is not conducive to
writing and reading.
Solution: DM907 adopts the latest laser light source, in addition to color, it
can synthesize the color gamut coverage of more than 90% of the natural color
seen by the human eye, achieving perfect color reproduction, at the same time,
brightness up to 4500 lumens, higher brightness and comparison The long service
life greatly reduces the maintenance cost in the later period. The color gamut
is wide, the brightness is high, and the service life is long. It can be seen
clearly without pulling the curtains off the lights, and does not affect the
students' copying notes.
Question 3: The traditional projector is easy to be blocked by the human body,
and the light is easy to glare on the face and the LCD screen is easy to use.
Solution: DM907 is an ultra-short-focus laser display projector, which is
installed on the wall. It can project a 100-inch large screen at a distance of
0.5 meters from the blackboard. People are usually in the area outside the
projector and the screen. The area will not have projected light to the eyes,
and the DM907 will be designed with more care and health. Teachers and students
can use it with peace of mind.
