The Benefits of DLP Projection

As a follow up to our post on The Benefits of LCD Projection, we will now explore the benefits of a competing display technology: DLP (Digital Light Processing). Currently DLP is one of the leading technologies used in digital cinema projection.

Older DLP-based projectors use metal-halide lamps combined with a color wheel. The mechanical color wheel is placed between the lamp and the DLP chip(s). The wheel is divided into multiple sections. Older models only use the three primary colors: red, green and blue, while newer projectors take advantage of the secondary colors as well: magenta, yellow, and cyan. This enables the projector to have a broader spectrum of color (This new color performance is called BrilliantColor). The chip is synched with the color wheel so that the current color of the wheel that is in front of the lamp is displayed on the DMD (digital micromirror device). The mirrors oscillate back and forth, either directing light to or away from the lens path to turn the pixel on or off. Each mirror relates to a single pixel. The wheel rotates at a high-rate (up to 10 times the frame rate) so observers can see the full color.

DLP models either offer single chip or three chip projectors. The difference is that in three chip applications, each primary color is sent to its own DLP chip, instead of all colors being sent to a single chip.

Newer DLP projectors are using high-power LEDs or even lasers for illumination, which eliminate the need for the rotating color wheel, which in-turn eliminates the "rainbow effect" (red, green, or blue 'shadows' that can sometimes be seen in high contrast or fast moving images).

DLP Projectors typically provide a larger size projection due to the fact that DLP projectors focus more on brightness and color saturation than LCD and in most cases, higher quality. Also DLP produces a great consistent picture. One of the biggest benefits of DLP is that is has a longer lifespan and its compact design.

Another benefit of DLP is that pixelation is not as visible as it is in LCD (this is known as the 'screendoor effect' in LCD projection). Also it has better black levels and contrast, which can be vital in video images.

These are some technical aspects to keep in mind when choosing the right DLP Projector Rental.

The Benefits of LCD Projection

Liquid Crystal Display (LCD) Projectors display images typically by using small metal halide lamps. These lamps are used because they produce a wide range of colors at ideal color temperatures. Additionally, metal halide lamps enable a projector to emit large amounts of light (on average 2,000 to 15,000 Lumens) in a small area.

The light from the lamp is dispersed through a series of dichroic filters (liquid crystals) to three panels, one for each color component of a video signal (red, green, blue). An electrical current is applied to toggle the color on or off, depending on what shade of what color is being displayed. This gives the LCD projector its wide color range.

LCD Projectors work great in areas where it is difficult to control the lighting in the room, such as rooms with several large windows. Since the metal halide lamps produce bright light, they perform better in these scenarios. Since the lamps are fairly small, they make LCD projectors good for portability and are lightweight.

Typically LCD projectors have a larger viewing angle as well, which is good for large rooms with several viewers that are not centered in front of the projector.

Its important to keep these benefits in mind when getting an LCD Projector Rental from RentOurProjectors.com

JVC DLA-X7 Home Theater Projector wins Prestigious 2011-2012 EISA Award

JVC's DLA-X7 home theater projector was the recipient of the annual EISA (European Imaging and Sound Association) award. Being one of the first projectors to achieve THX 3D certification, the DLA-X7 boasts several impressive attributes. This projector offers an incredible 2D/3D experience with an astounding 70,000:1 native contrast ratio and a bright 1300 ANSI Lumens. Designed for use with 3D active shutter glasses, the DLA-X7 enables consumers to enjoy a full 3D experience while allowing for variety in choosing screen types. Additionally, this award winning projector has a powerful color management system, video processor and custom gamma control.

EISA is a collection of 50 magazines from 19 European countries, the winning products are chosen by the editor-in-chief of each magazine. Any product covered by the magazines during the past year are eligible to recieve the award.

EISA has created a short video clip about the DLA-X7 to honor JVC's achievement this year.

Apple Files Patent for Projectors in Devices

Apple just recently filed a new patent which they just published that hints at the fact that projectors could one day end up in some Apple devices including things like the iPhone, iPad or as an accessory in the company's line of notebooks in order to help make it easier to share content with others.

The application entitled "Projected display shared workspaces" was filed back in February 2010 and pulled up yesterday morning by Patently Apple. The patent outlines a system for taking what is on screen and projecting it onto a close surface. The interesting thing about the proposed system in this particular patent is that it has the ability to combine projections from multiple devices into one screen, hence the name "shared workspace".

The patent application notes that "consumers frequently share data stored on electronic devices with other people," however, portable devices usually come with small screens, thus making it harder for people to share things with a group. Apple's solution promises to solve all of that by offering a way for devices that have projectors to link up to one another. The result would be a bigger canvas for presenting media and other documents, using something like a server or Bluetooth to transfer the data between devices.

Another interesting piece of information that goes hand in hand with this patent application is the fact that Apple is connected to the domain Applepico.com. Pico Projectors are the commonly used phrase for small projectors found on point-and-shoot cameras, cell phones or as standalone devices.

However, this is not the first Apple patent application to look into integrating projectors onto portable devices. Another filing that was uncovered back in April of 2010 detailed the construction of a projector in a notebook. One month before that, another filing was shown detailing how projectors could be used if attached to a phone. This led to a 2007 patent filing which detailed using attached or built-in projectors in order to display media.

Pico projectors are continuously getting smaller with new technology constantly decreasing the physical space and power required to put a built-in projector on a portable device. Alps Electric just recently announced a new lens that measures just under 1mm square. Alps Electric plans on producing these lenses in bulk by the end of 2012.
