"DLP vs. LCD Home Theater Projectors"
Projectors essentially convert video data and signals into light, which is beamed to a screen where the corresponding image is produced.

These home theater projectors which vary with respect to costs, portability, and of course, technology, treat light differently with different results, variously affecting intensity, resolution, size of image and of course color of the image. Sight or visual perception in the human brain being the result of reflection of light from objects, the capture of data relating to reflection and absorption of light by an object or objects, is what drives projector technology.
The LCD home theater projector, also known as liquid crystal display projectors, involves the use of liquid crystal display panels which are mapped out in pixels, the opening of closing of which modulates light proportionately to produce the corresponding image. The number of pixels is what constitute resolution, with higher resolutions indicating capture of more data and hence better or more faithful reproduction of images.
In choosing between the different home LCD home theater projectors for the theater experience, the parameters to be assessed would include intensity of light produced, the resolution, color conversion technology, the size of the images produced and of course contrast ratios, which is affected by the ambient light produced in the viewing room.
A common choice for church use, the LCD projector is the most popular home theater projector, being a favorite choice for various reasons of cost, ease of use, good quality video and portability, particularly since the development of the dynamic iris technology which effectively handles contrast issues.
Options in screen are either aluminum of glass bead screens, measured by 'screen gain', which is the measure of reflectivity of light as compared to that of a screen coated with magnesium carbonate or titanium dioxide. Other types include the DLP or digital light processing technology, besides LCOS which is Liquid crystal on silicon technology.
