.puters-and-Technology You have decided that it is time to purchase some new presentation projectors for your .pany but you dont know where to start. You know that it is important to get a machine that is functional, reliable and affordable, but you also want one that makes colors pop and contrasts spike. You will need to be.e familiar with your options before you make a purchase in order to get the best machine you can. The projectors presentation devices that are used today are available in different colors, bringing cinema theater quality to your meetings. Advanced technology delivers distinct, crisp and clear contrasts and brilliant colors like never before. Images .e to life, and between the incredible picture and great sound quality, these are not your business projectors from the 1970s. You have to understand how these machines work to make sure that you are going to end up with the portable presentation projector that will be best suited to the needs of your team. There are two main types of digital projectors right now, so you need to start your search by understanding the difference between them before you move on to other characteristics of machines. The presentation supplies and projectors rely on receiving an electric signal from a data source to work. The electric signals are either digital or analog, with data sources being things like DVD players, Blu ray players, etc. The electric signals are transformed into the image that is projected onto the screen for everyone in your meeting to enjoy. One note: if the signal that is sent is analog, it will have to pass through an analog to digital signal converter to transform into the digital signal. The two types of digital projectors that are available at this point are LCD (liquid crystal display) projectors and Digital Light Processing (DLP) projectors. In a LCD digital conference room projector, the digital signal is processed to polysilicon panels. A light source is passed through a series of dichroic mirrors. Mirrors that are dichroic separate the various color wavelengths and then through the polysilicon panels. Then, activated pixels process the light into a final .pilation, which is then projected through the lens and onto the screen. The DLP projectors use something called a DMDT chip to process the digital signal. The light source is passed through a color wheel and onto that chip. The light then is reflected off of the chip through the lens, then onto the screen. This is pretty new technology, and it has led to a revival of sorts with presentation projector systems and the miniaturization of the industry. For more information about these types of machines and all of the options available to you, be sure to spend some time on the Inter. researching what the market holds. About the Author: 相关的主题文章:
