LCD Projectors (Liquid Crystal Display)
LCD Projectors function by spotless light through transparent LCD cells. Most LCD projectors us advanced polysillicon LCDs, which use three separate color panels (red, green, and blue) to produce the preferred color. Projected images are produced by the combination of light shinning through the LCD cells. LCDs have excellent color saturation, usually have adjustable brightness and contrast, are typically brighter than DLPs at the same lumen output, and they have a broader range of connectivity.
DLP Projector (Digital Light Processing)
DLP projectors were developed by Texas Instruments and project images by reflecting lights against hundreds of little mirrors called digital micro devices (DMD). Each mirror representing one pixel is powered by electronics that adjust the angle of the mirror according to the color being displayed. DLP projectors are lighter in weight than their LCD counterparts. They are all digital technology and typically have higher contrast ratios, meaning that they project video images better than LCDs. They are portable, tend to be smaller and lighter than LCD projectors and connect easily to other digital devices.
Projector lamp can transfer an image from multimedia projector onto a big screen for audience to view. They convey information to all kinds of audience from business organizations to education organizations.
Halogen Bulbs are mainly used for projection purpose for many years. These halogen bulbs produce a yellow tone on images. Projector lamps produce white light with the help of metal halide bulb. The produced white light shines onto a number of small glasses in the projector and passes the image through air and onto the screen. There are three main types of projector lamps overhead projector lamps, slide projectors and multimedia.
They have a flat surface. The image created by the bulb is sent to a special type of mirror which makes the image bigger and projects onto a blank screen. These type of overhead projectors are used in class rooms for education purposes. Business people can also use these in conference and meetings.
They contain a special slot for 35 millimeter slide. Slide shows are best used by business people and teachers who rely on demonstrating things. Photographers use these for special photography projects. They are easy to store and you can rely on them for long time.
The multimedia projectors are the most expensive. They project images, videos to a movie screen or onto a wall. They are used at movie theaters and expensive home
TOSHIBA TLP B2 Ultra Bulb TLP-LB2P
Price: $611.18
The Toshiba TLP-B2 was released in May of 2000, which in the projector world makes it somewhat of a dinosaur. But, the projector was tremendously popular at the time of its release and many people carry on to use the unit and buy replacement projector lamps for it as well.
The projector lamp for the TLP-B2 goes by the name of the TLP-LB2 and is a 120W projector lamp. The projector lamp outputs an eye-popping 1000 ANSI lumens, which is a ton for a projector that was manufactured back in the year 2000 and utilizes a 120W projector lamp. Usually brighter machines will employ projector lamps with higher wattages, as these lamps tend to be able to produce a brighter ANSI lumens rates. However, the Toshiba TLP-B2 is an exception to this rule.
Users of the Toshiba TLP-B2 generally have heaped praise on the unit. The number one draw to the Toshiba TLP-B2 is its small design. The projector has a footprint of only 24cm x 27cm making it one of the more compact units to be released in the first half of the decade.
There are some drawbacks to the Toshiba TLP-B2 that are merit mention. While the projector is solid and bright, some users do complain about the noise that the fan makes. These complaints range from huge disappoint to mild annoyance, however, it is clear that the projector’s fan does make more noise than the average projector.
Reviewing some of the other specs on the TLP-B2 one finds that the contrast ratio sits at a quality 400:1 level. The projector is not HDTV well-matched but does include personal computer and video inputs. The projector operates with an aspect ratio of 4:3 and a native resolution of 1024×768, which can be ramped up to a maximum 1280×1024 – another strong feature of the TLP-LB2.
