Why Laser Projector Is The Future Of Projector? (Part II)

In the last article, we have talked about the benefits of the laser projector, now we’d like mentioned something you must care about when purchasing the laser projector.

There are many models to be optional on the market and each one counter different prices. You may get confused why some models are cheaper or more expensive, how do you choose. Here, I want to advise two key points for you:

1.DLP chip.

The different chip will totally counter different prices, 0.47 DMD with great prices but maybe not perform very well in brightness, test result shows it can achieve at most 1200-1600lum. Another disadvantage of 0.47chips is it not suitable for big screen, it may occur color fading in size like 100inch. The latest DLP technology used in the projector now is 0.65DMD, which have much improved in both problems.

2.Fewer laser, lower prices.

You may also notice that laser source has a pure laser and hybrid laser. Pure laser working structure is: Laser source with phosphors to create light as following picture shows.

For hybrid source, working structure is: LED source+ Laser source+ Phosphors. One benefit of the hybrid is saving cost.

Use the hybrid source, it may emerge three questions:

2.1 Hybrid SSI(ReD +Laser or Red/Blue+Laser)will generate imbalance question due to different color source.

2.2 Due to the large light-emitting angle of the LED, the light-emitting angle relative to the laser light source is small, and the optical system can not collect more light energy to increase the brightness by increasing the number of LEDs, it will cause hybrid source with bad light collection efficiency, on account of this, it will reversely result in hybrid projector in high brightness mode must sacrifice color balance, if choose the color balance mode must sacrifice brightness, it will only 1500 lum.

2.3 Hybrid source (LED & Laser) efficiency decay trend inconsistent, long-term use will result in can not maintain color balance, will also affect the lifetime of the projector.

3.Bottom Line

So many benefits of laser projector as I mentioned, but it still not popular in the market,why?In other words, What’s its disadvantage?That’s relatively expensive compared with traditional lamp projector, So how much will it cost for laser projector?The price will vary due to different chip and the laser source, different configuration required depends on your needs.Another solution for this disadvantage is IQ projector with 0.65DMD, pure laser projector are in end-year promotion, you can get this product with best prices ever,if you’re interested, don’t lose this opportunity.

Any market to accept new products will take time, the thing we can do is to go ahead than others, or we will leave behind by them.Lasers provide unparalleled superiorities, there is no doubt that laser projector would be the future of the projectors!


What A Peculiar Encounter with Snowing Huangshan Mountain -IQ Annual Group Travel 2017

It’s quite exhilarating for IQ members to come and see snow as there rarely snows in the south area of China, especially for Fuzhou city where our headquarter locates. Therefore, IQ’s going to visit one of the world cultural heritages-Huangshan Mountain-as our destination for annual group travel 2017. Get ready for the snowing world.

At the first day, we were heading for Huangshan Mountain. Even at the foot there’s falling snow already. Knowing that the temperature would be much lower than that of downtown, everyone was wrapped up to keep warmer.

Guess whether our little boy reached the summit or not with such heavy coat.


The journey began with a long slope called as Hero Hill. And yes we are all heroes after climbing up the hill.

Then we were attracted by the famous landmark of Guest-Greeting Pine which stretches out from a cliff to welcome visitors from all over the world.

Could you find it in the picture below?

Though it’s not easy to walk downstairs by clinging to the rope, we were not held back and taking care of each other to finish the trip.

It’s tiring but meaningful. Along the journey was full of laughter.

Wrote down IQ to give direction for the way ahead.

And this is IQ team spirit.

The beautiful scenery and smiling faces.

The next sunny day we paid the visit to the local towns.

Time flew by and travel came to the end. Here are some lovely pictures ‘behind the scenes’. Come have a look.

Weightlifting game:

Was it more attractive to view from such a strange angle??



Why Laser Projector Is The Future Of Projector?

As you may notice, more and more laser projectors have come to your view gradually.In the past, laser source projector mainly used in the outdoor and professional theater display, but now it increasingly applied in the business, education and home theater.So what is the laser projector, what exactly makes it different from traditional lamp projector?

Firstly, vivid color and ample brightness. Laser projector can achieve far greater color space than the traditional light, its color performance is more than 2 times the traditional projector, high color saturation, can truly restore color.Due to the low attenuation of the laser light source, Laser projector makes its output quality maintain high brightness, color saturation and contrast in the long-term, the picture color has always been staying the same.

Secondly,20000H lifetime and free maintenance.Most of lamp projector lifetime is 3000-6000 hours in the standard mode(5000-8000 hours in eco mode),laser projector is 16000-20000 hours in standard hours(maximum to 30000 hours in eco mode).

Normal lamp projector needs to maintain replacing the lamp regularly, and may occur rupture or explosion due to the unstable lamp structure. By comparison, on account of the high reliability of laser structure, laser projector can truly achieve maintenance-free use: no danger of lamp exploding and lamp replaced should be at least a decade.

Thirdly, High efficiency and energy saving.As the light source, the blue laser beam will be turned into red, green and blue light by the color wheel, then RGB light will be projected on the DMD chip to almost 100% display the image on the screen, which means laser only create the exact colors needed, which uses less power. But for the normal projector create light, the projector will waste most of this light, only leaving the red, green and blue parts, inefficient and energy-costing.             

There are also some other awesome advantages with laser projector, ultra short throw create a big screen,3D application,dust-proof design, nearly instant on/off, no need to warm up or cool down is cool for projector owner.If you’re interested,you can learn more in IQProjector or inquiry to grace@iqboard.net directly.

Knowing more about laser projector, you may wonder how much does laser projector with so many unparalleled advantages cost?And What should you pay attention when purchase?

I will clarify detail on these question on next article(Part II) later.

Why Classroom Management Is Important for Teachers?

In addition to being highly knowledgeable in the subject matter, teachers also need to know how to manage classroom dynamics effectively. This entails organizational and disciplinary skills that both help make different types of classroom interactions more systematic and aligned with the learning objectives. Otherwise, classes that are conducted by teachers with very minimal classroom management skills tend to produce less favorable outcomes, such as low student achievements. Some studies, in fact, suggest that when teachers are inefficient at managing disruptive classroom behavior, the average pace of cognitive development among all students suffer greatly.

If you happen to handle classes where disruptive behavior is present, then there are classroom management techniques that you can implement to reduce or even eliminate disruptive classroom behavior. This article presents two solutions–one a process and the other a set of methodologies–that you can use in various combinations depending on the learning conditions in each of your classes.

Class Management Process

This set of steps aim to transform the classroom environment into one that actively encourages learning. By modifying both the physical and human aspects of the classroom, teachers will be able to establish an ecosystem that has a positive atmosphere and one that compels everyone to attain learning goals.

  1. Have a plan.Nothing beats a comprehensive strategy for achieving learning goals. Each learning session must follow a pre-planned outline that details 1) the expected learning outcomes; 2) how the teacher is to introduce, demonstrate, or explain a lesson or subject matter; 3) the techniques by which the teacher will motivate the class to actively participate in the learning process; 4) how the students will participate; and 5) the alternative strategies in case the actual learning outcomes and student behavior are not what has been expected.
  2. Establish the best learning climate possible.Excluding human factor, the overall learning conditions in any classroom can be modified readily. How a room looks and feels have a direct impact on learning. Lighting can be configured depending on the teaching purpose, for example (well-lit rooms facilitate clear reception of all sensations especially those that are visual while a darkened room magnify sound sensations and may be good for articulating pronunciations, and other verbal concepts; a spotlight focuses students’ attention to a particular learning stimulus such as the teaching conducting a lecture, a visual image, or the whiteboard.). Get rid of disruptive background noise (a faulty electric fan or air conditioning unit, for example) whenever possible. Clutter and other visual pollution that unnecessarily divert people’s attention should also be addressed.
  3. Conduct class sessions efficiently.Clarify the goals you want your students to achieve and the ways by which they can achieve them. Never appear to be disorganized to your students. Be consistent in order to set an example and establish a clear system for different classroom activities.
  4. Practice authority positively.Develop mutual respect but integrate wholesome humor in your interactions. This will allow you to reach out to all your students and to avoid neglecting anyone. Maintain a positive and accessible demeanor so that your students will be encouraged to communicate. Practice the so-called three F’s required of successful educators: firmness, fairness, and friendliness.
  5. Class Management Techniques

Managing student behavior is critical to the success of your teaching sessions. You can use any of the following techniques in order to establish the right learning attitude among your students.

  1. Subject Focus.Everyone in your class should be primed for learning before you introduce a new subject matter. When students are engaged in chatter that is unrelated to the subject matter or appears to be doing something not related to the lesson, don’t continue your teaching until you get their full attention. Temporarily stop discussing the subject matter whenever you think students are not paying attention since that would be a waste of time and effort. Otherwise, opting to teach even when students are not paying attention will establish the notion that it is okay to be rude and to ignore someone speaking to you.
  2. Modelling.For the learning process to be healthy and effective, teachers need to establish their leadership and authority inside the classroom. They also need to exhibit the very traits they want their students to develop and possess. As role models, teachers should know and practice how to show respect and concern for others so that students can emulate their actions. In addition, teachers should show decisiveness and fairness in order to establish a good, disciplined environment for learning.
  3. Proximity and Modality.Students tend to be more involved when teachers are at arm’s length compared to when they are more distant. This is because people tend to do whatever they want to give the chance to do so. In a classroom setting, students in locations that are farthest from the teacher are likely to do their own thing and misbehave compared to those who are in close proximity to the teacher. To address this issue, move across the room during lectures or seatwork as much as possible. Equally, engage as many students as possible and make it clear that you confer due attention to everyone and care about their learning achievements.
  4. Reward System.Teachers should understand what motivates students and use these as platforms for cognitive development. Human needs such as a sense of belonging and affirmation can be used for further nurturing good classroom behavior. Also called “Positive Discipline” by some educators, this technique showcases positive traits instead of calling students’ attention to bad behavior. Praise and reward often accompany this technique and are used to reinforce everyone’s preference for good behavior.
  5. Regular and Random Aptitude Assessments.To check whether students are learning as much as expected, teachers should give regular tests in the form of announced exams, seat works, group activities, and other assignments such as random concept checking. Unannounced quizzes should also be regularly given not only to monitor students’ progress but also to compel students to consistently pay attention in order not to fail in the surprise quizzes.
  6. Lesson Management.The teacher’s understanding of people’s motives and behavior is just one side of the coin. The other side concerns teachers themselves. The fact is, while it is assumed that teachers know their subject areas adequately, sharing their knowledge is another matter. Due preparation and planning are necessary to conduct each learning session successfully.

Teaching is a rewarding profession and is critical in preparing the next generation of people for meeting the challenges of tomorrow. It can also be a highly stressful discipline especially for new teachers who are easily intimidated by adverse classroom dynamics. These guidelines should be able to help teachers streamline their classroom engagement strategies in order to yield positive outcomes–both for them and their students.
