![]() Using a cheap LCD panels can result in nothing more than an expensive paperweight. Normal LCD (Liquid Crystal Display) are not designed to be used in high-heat environments. Picking a cheap LCD monitor off the shelf for instance is a bad idea. There are a lot of articles with little to no foresight in this type of project. Now, here is where I have to return to the point that this may not be the first how-to article. There are many ways of using LCD‘s of many verities. Light passing threw the LCD creates the viewable content. LCD projectors act on a similar principle. Light passing threw the film, and interacting with a shutter created the viewable content. Historically, cellulous based films were used as the imagery medium. The Imagery Medium – The LCD Projector Panel So what are the most common practical light sources? All bulbs are sensitive to shock, getting bumped too hard can be a costly mistake. Commercial or non DIY projectors can have bulbs that are very very expensive, often in excess of $500.00 for a bulb that usually can only last for 2000 hours. Most all LCD based projection use Xenon or filtered Metal Halide, based light sources. Xenon’s were introduced in the 1950s, they are safe and easy to use, and are relatively cheap. The Light Source – The LCD Projector Bulbīack in the day traditional carbon arc were used in actual film based projection, but modern xenon arc lights are now more common. We will be glancing over them and providing some examples that could fulfill the requirements for our LCD Projector. There are many ways of accomplishing each of these requirements. You need simply 4 requirements to be met: a light source, the brighter the better some form of imagery medium, film or LCD it’s all the same conceptually a focusing mechanism to help provide a crisp image and finally a display medium. The principals that make projection in general possible are very simple in concept. We have hand tested each model shown and will update it frequently. So instead of answering 5 billion emails individually we put this break down on panels together. We have also received a plethora of questions on panels (would this make us in-famous?). We have been nearly overwhelmed with fan mail over the DIY Projector project. We let you decide what components are right for you, but give you a fully functional example. So what makes this guide practical? Simply put, the theory behind projection coupled with the breakdown of costs for each main component of the projector. ![]() Home theater receivers and a strong stereo system, along with this projector can make you feel like you are at the movies. ![]() For years people have been trying to make their own projectors due to the high cost of real LCD projectors. ![]()
