Projector Maintenance costs climbing up through the roof?

Projector Maintenance costs climbing up through the roof?

Built to Last + Filter Free = Lower Total Cost of Ownership with BenQ DLP projectors

More and more projectors are sold either for office usage or for home cinema. Formerly LCD projectors were less expensive compared to DLP projectors which were known as more reliable – both in performance and in maintenance. Nowadays, DLP projector prices decreased significantly. So the arguments to purchase DLP projectors are increasing even more.

But what happens after the purchase of a projector? What is the TCO (Total Cost of Ownership)? How can the user take care to reduce the TCO for projectors? Below there are the main indicators for TCO.

Top Three Costs of Owning a Projector
1. Filter cleaning and replacement
2. Lamp replacement
3. Color decay and cleaning

What criteria influence the TCO? Which trouble does a user face? Mainly it is dust!

How can dust affect a projector?
• Clogged filters may increase the operation temperature – the projectors goes hot
• Can reduce overall lumens – less brightness
• May reduce contrast and readability – bad performance
• Images can look dull/colorless – colors do not match anymore, the color spectrum decreases

LCD Projectors - Maintenance
All LCD projectors have filters with a typical LCD projector recommending filter cleanings as often as every 100 - 300hours. What if the filter is not cleaned and gets clogged? Optical components can overheat and be vulnerable to dust contamination. A clogged filter means an increase of the temperature which can significantly impact the contrast and brightness and also the lamp life. This can happen every month to three months depending on the usage time of the projector.

The filter replacement or even the filter cleaning often requires the removal from stand/ceiling mount.

BenQ DLP Projectors - Sealed Engine - dust resistant/filter free
All BenQ projectors use the DLP technology (a patented technology from Texas Instruments), which provides necessary motive power to make the pictures look sharper. This industry recognized technology improves color accuracy and enables better use of lamp spectrum to achieve brighter projection. Plus, all DLP projector components are completely sealed so that dust cannot affect the image.

What factors reduce the maintenance of DLP projectors?
• The DLP chip and the optical engine are completely sealed
• DLP Chip is cooled from the back – lower operation temperature
• Enables filter-free projectors

Due to the sealed DLP chip - with glass over the front of the mirrors – no dust can settle on the mirrors and block the picture. The DLP chip is a semi-conductor device and not a panel so it can be cooled differently than an LCD panel. The DLP chip uses mirrors which reflect the light so they are cooler. The DLP chip is cooled from the back and enables manufacturers to design a sealed optical system preventing dust from settling on key optical components and eliminating the filter from the projector.

There are over 160 Filter-Free DLP projectors on the market today from leading brands. 

Who benefits from less maintenance cost the most?
• Education  Classroom environments have high levels of dust
• Places of Entertainment - Sports bars and karaoke bars have high amount of smoke
• Industrial environment - Power plants, steel plants and mines have high concentrations of residual particulate matter
