Keeping Your Classroom Always Up and Running With Dustproof Projectors

What Influences the Future of India’s Education Sector?

Higher education in India has brought about a transformation in the country's GDP at the turn of the century. But the imminent threat to schools’ edtech investment from the deteriorating environment requires the help of technological advancement to safeguard values of the investment.

What Influences the Future of India’s Education SectorAccording to studies, it has been proven over time that uninterrupted and interactive learning has been a validated tactic to increase retention and assimilation of information in Indian students. Indian schools have implemented smart solutions to offer an affordable yet effective education to the masses. 80% of India’s school teachers have agreed to the smart educational system.Interactive displays such as projectors, form an integral part of the modern, technology-driven education sector in India, hence making them extremely viable to the cause. However, quality of the Indian education system is not as positive as expected due to the lack of smart solution adoption and the rising costs of maintaining them.

And dust is the key factor to the rising maintenance cost.

AQI (Air Quality Index) Indian ShoolsBased on the latest WHO list, India has the dubious distinction of being home to 22 of the 50 most polluted cities globally. Indian schools have open playgrounds with sand pits, and most classrooms are subjected to no windows or open windows. Adding to this, the AQI (Air Quality Index) levels are higher inside than outside, meaning that the level of harmful particles in indoor environments is higher than that of outdoor environments. With around 100K units of projectors being installed annually across India’s classrooms, the potential threat posed by harmful dust in the environment is imminent.

How does Dust Damage the Value of Your Projectors?

Proper precautions are necessary, especially when we witness such changing times. With air pollution at its peak in India, the need of the hour is to focus on damage control excessively. Recent studies show alarming numbers of dust pollution, and hence, classroom projectors have been adversely affected by dust. Proper dustproof mechanisms will assist in extending the lifetime of projectors. Without such mechanism, the maintenance costs will be significantly higher, leading to an increase in unnecessary expenses.

In the absence of dustproof technologies, projector’s performance could experience the following:

  • Picture Quality Deterioration -Due to dust accumulation on internal parts, it could lead to the deterioration of image quality, image blemish, and colour decay. Ultimately, this can affect the overall learning experience in classrooms.
  • Thermal Issue-If certain amount of dust is accumulated in the filter or the ventilation system, it will lead to projectors’ airflow being considerably reduced, resulting in overheating and undesirable maintenance costs.
  • Total operational breakdown- When dust accumulates on colours wheel of projectors, the projection will result in abnormal colours, flickering and may eventually cause shut down without warning.

Dustproof Technology to Safeguard the Future of the Indian Education Sector

Dustproof Technology BenQ-ProjectorProblems caused by harmful dust can be avoided in the long run by taking corrective measures. BenQ’s Dust GuardTM Series has passed testing in a simulated environment with large amounts of fine dust, soot, and milled cotton lint. It filters out large amounts of harmful dust and allows projectors to become invulnerable to them. Also, with the sealed optical engine design, the anti-dust accumulation sensor and dust filter, the dustproof mechanism enhances the safety of the projector.

The dustproof solution ensures optimal reliability and performance by extending projector’s lifeline, reducing maintenance frequency by ⅓ and ensuring high image quality without colour decay. It also blocks out 90% of particles and PM 2.5. The Dust Guard series is also equipped with smart eco-technology, further ensuring reliable eco-friendly operation in classrooms.

The education sector will continue to grow in the next few years. To ensure all Indian students receive the best quality education, it is time to look for relevant solutions in order for us to define our path to future success.
