- Can show largest possible picture - font projectors generate a biggest possible image size
- Smaller image can be agreater option - if you do not want a huge image or may be yoy dont have enough space u can can trow a smaller image.
- Space saving - a smaller projectors that is mounte on the coffee table or book case cannot finish up the floor space
- Easy to install -the easy of istallation can vary actually (http://www.hdtvsolution.com)
Audience reach - Before computers came to dominate the classroom, overhead projectors were a popular tool for teachers wishing to enhance standard lectures with supportive visual aids. Businesses also found them useful for presenting visual aids during meetings and conferences. The overhead projector is suitable for presenting material for a range of audience sizes from small classes to large business conferences. (http://www.ehow.com)
User friendly - Overhead projectors are relatively easy to use. Those who may not be technically savvy enough to create and present a PowerPoint slideshow for a computer presentation will benefit from the user-friendly mechanics of the overhead projector. (http://www.ehow.com)
Rental savings -Overhead projectors are available for purchase at many office equipment retailers, although if you only require a one-time use, you may save a lot of money by simply renting one.
- No convergence problems. All projectors using three imaging devices, whether they are LCD, DLP, or LCoS, must have all three devices aligned perfectly so that the red, green, and blue information for each pixel is in convergence. (http://avm-technical.co.uk)
- Contrast advantages. Most business class DLP projectors have much higher Full On/Off contrast ratings than comparably priced LCD models.
- No image persistence. If one displays a static image for an extended period of time, an LCD projector with organic LCD panels may have a tendency to retain a subtle ghost of that image even after the subject matter is switched to another images
- No degradation of image quality over time. There is usually no degradation of image quality on DLP projectors when used over long periods of time, other than that which might result from excessive internal dust build-up. (http://avm-technical.co.uk)
Conclusion
The main aim of this project was to discuss how importance logistic department in the Nmibian defence force the career oportunity and the good thing to join this special department. and the the advantage of technology through projectors, technology lay a good fundamental foundation in the learning environment and make it easy for the the teacher or instructor to interact freely with the learne by providing quality teaching aid. This teaching aid crotribute alot because and make it easy for the learning to take place. There for is of the most important for the instructor to select over head projectors in order for him or her to facilitate the lesson plan without any difficulties. This signifacant contribution of technology towards teaching process is very much recomendable.
