How much do you know about mini projector
With the business activities increasing, more people need portable projector for high-quality presentation. So now does the projector meet people's needs? What styles does portable projector have?
Family of the projector
Viewing the current projector from the chip projector (image processing), it consists of LCD (liquid crystal) and DLP (digital processor) projector. As the two chips of different sizes, different imaging principle, so two different chips, the size of the projector is also different.
LCD mini projector is the core component of LCD panels, the technology used in projectors that the older, more mature technologies. With LCD 0.5-inch LCD panels in use, and improved optical design, LCD projector products have reached the weight of about 1.6kg, the portable has received a good development.
In contrast, DLP portable projector, thanks to DMD chip, an advantage in portable performance. Generally considered less than 2.5kg in weight portable projector projector, and processing technology using a portable DLP projector, weighing up to 1kg or so, it was dubbed the super lightweight projector.
Form factor portable projector can use a notebook computer bag sized bag carrying.
Scope of application of portable projector
In general, the application of portable projectors for business applications is not usually used to demonstrate the complexity of video and animation, but in general static documents, charts, for example, Word, PowerPoint documents such content, portable projector can meet.
Application of portable projectors for mobile business presentations and training of personnel participating is in dozens of people generally within the projected area in 60 inches or less. So, do not need a portable high brightness projector.
Indicators should be considered when choosing
In choosing a portable projector, the performance index is different from the standard product. Buying portable projector specifications needs to pay attention mainly brightness, contrast, resolution, lamp life and service.
Portable projector lumens brightness indicators are generally between 800 to 2000 lumens. Users select portable projector, the projector according to their size requirements, the environment brightness projection to determine the brightness of the projector the size of purchase. In general, if the demo environment of 15 square meters, poorly lit, then the projection brightness of 800 lumens is sufficient, if the presentation environment, there are some light, then the 1000 lumens is appropriate, if the open space, light environment should be considered about 2000 lumen projector. It should be noted that the current general machine in the whole semi-dark room to bright light can have good results. Brightness projector projector also because of different distance, the projector farther away from the screen, the image brightness will be lower.
Contrast imaging principle according to the different chips, in general, portable LCD projector may reach 400:1 contrast ratio over the DLP portable projector 1000:1 contrast ratio can reach over. Obviously the indicators in contrast DLP projector is better than LCD, but this does not mean that we must choose DLP projector, and in fact the general document projector can only 400:1 contrast ratio. Users can choose when to try projection effects.
Resolution of some store staff will advise you to buy the best machine image resolution, while the reporter recommends that users according to their actual usage selection. For example, if your projector and notebook computers are used for use with, then you select and present the same Notebook resolution projector ideal. Portable projector is now available to the general resolution of 800 × 600, can meet the needs of the general projection. At the same time, we should note that the prices of general projector with resolution enhancement and growth.

A couple questions on home theater projectors?
I am looking at getting a home theater projector for my living room but i dont know much about them, a couple questions i have are, first off the one i am looking at says it projects 40" to 200" now is the 200" the size at which it starts to destort or does it do that before?, also it says projector distance is 4.5 feet to 32 feet, do they have to be super far back to project say a 90" screen? and then the final question i have is in tv's dlp looks alot better than lcd is the same true for projectors?
I've provided links for further info on the answers below, so don't worry if they don't make too much sense right now.
Screen size is a function of the lens and distance from the screen. For most rooms you wouldn't want a screen bigger than about 100"-120" (It gets too overwhelming). Ideally you aim for a viewing angle (the horizontal angle between left & right edges of the screen viewed from the viewing position) of 30-40 degrees. So, the 40" - 200" is pretty meaningless. You can go smaller but it will be very bright and you probably can't get to 200" and have much brightness left. Distortion isn't an issue unless you get things "wrong".
All projectors have a "throw distance range". That's the range (from projector to screen) over which you can mount the projector and get a useful range of screen sizes and also stay within reasonable brightness levels. The throw distance range varies with the projector lamp and optics.
DLP projectors used to be a sure bet to be able to give better contrast and deeper blacks. That is no longer a given, though in most cases it's still true.
See the links for a viewing distance calculator, a throw distance calculator and sites with info and reviews on projectors. The info above will make more sense after reading some of the info on the sites below.
Hope that helps
