For the students, nothing is more offensive than 'the teacher loves class', but in fact, if not to ensure the integrity of teaching, the teacher would not want to drag class and ring the lesson plan In fact, any teacher with a little qualification, regardless of whether he is writing a detailed lesson plan or designing a classroom, will carry out time budget management for each part of the course and may not be able to attend the classroom Accidental default solutions, such as taking into account the number of bear children in the class particularly love trouble, each class will be reserved for 2-3 minutes to maintain classroom discipline. Try to do not take up spare time.
Even so, accidents always come.
Classroom projector is a problem, PPT half, suddenly automatically shut down, press the remote control, press the control panel buttons do not react, the teacher originally intended to give students to see on the flight characteristics of birds to adapt to the video After class, look for the school's network staff, it really is because the filter too much ash, the machine can not effectively heat, and finally because of overheating protection and choose to automatically shut down.
But for the teacher, the more headache is the brightness of the projector.Each time to the courseware, there are always back row of students reflect the projection screen is too vague, can not see, so, in order to facilitate the copying, you need to verbatim Slowly read again Caixing, encountered more content, it will affect the efficiency of the class.
If the school changed the BenQ DX808ST short-throw projector dust situation will happen?
20mm single-layer filter can filter 90% of the dust impurities, to prevent dust inside the instrument, but also equipped with intelligent monitors inside the machine will automatically remind the user to replace the filter, to avoid over-weight filter will affect the normal use of the machine.
More specifically, the DX808ST uses a convex design infrared sensor color wheel, which is easier to receive and transmit infrared signals and less fouling than the traditional concave infrared sensor color wheel to reduce the situation of shielding infrared signals and ensure teaching Activities are normal and orderly manner.
Moreover, the brightness of up to 3,300 lumens, even in the bright classroom also promised to project a bright, clear images, even if the final row of students can see the whole picture content.
From the fully enclosed light machine, Yamagata fold dust filter to the infrared sensor color wheel, from the updated iteration of each of the dust-proof technology in BenQ, we can see that the education industry users pay attention to dust-proof performance, 'user needs Spend 80% of the time to solve the problem that is the core needs of our products', in the pursuit of user experience on this road, BenQ education projectors have been insisting.
