Understanding Front-projection TVs - LCD

LCD and DLP are very close in terms of performance, and even LCD's ability to produce good blacks has improved quite a bit. DLP still enjoys a slight edge in contrast ratio, however, mainly because its projectors can get a bit brighter than those of LCDs. The screen-door effect, which appears as a fine grid of pixels overlaying the screen, is also more noticeable on most LCD projectors. As we mentioned above, however, 720p LCD projectors still enjoy more features than their budget 720p DLP competition, including highly desirable items such as horizontal and vertical lens shift. No consumer-priced 1080p LCD projectors are currently available.

Upside:	Downside:	Forecast:
Can get extremely bright; decent uniformity; generally better black-level performance than LCD.	More expensive than similar-resolution LCD models; rainbow effect.	Already the most popular technology for home-theater projection, new less-expensive 720p versions will make DLP even more desirable.

Projector Lamps - FAQ

1. image seems dimmer than usual - what does this mean?
   
   It may be time to replace your projector lamp. Projector lamps dim as they age. Some projectors allow you to check the number of hours your lamp has been used through the built-in menu system. Check your user guide for information about this feature.
   
   
2. How many hours will my projector lamp work?
   
   Just like any light bulb, projector bulbs have an expected operating time, called lamp life. This value is expressed in hours and represents the number of hours before the lamp is at half its original brightness.
   
   The expected life of a lamp will vary based on the lamp technology and the projector; however, most projectors offer about 2000 hours. The lamp's success rate is based on a bell curve, so that a majority of (but not all) lamps will meet the lamp life hours specified. Some lamps will fail sooner and this is part of the acceptable operating range of the rating.
   
   For projectors that are used under normal operating conditions (no more than three to five hours per day in a clean, relatively dust-free environment) the lamp will have the greatest likelihood of lasting through its entire rated lamp life.
   
   
3. What can I do to help my projector lamp last longer?
   
   There are several things you can do to increase your lamp life. Do not allow the projector to become overheated by ensuring that there is adequate clearance near the intake and exhaust vents.
   
   Operate your projector in a clean, relatively dust-free environment.
   
   Clean air filters every 3 months or more often if there is a lot of dust or contaminants in the room.
   
   Striking the lamp ages the lamp as it causes slight changes to the shape of the electrodes that light the lamp, so light up your projector when you're ready to use it and avoid frequent on and offs.
   
   Avoid shock to the lamp or projector.
   
   Use "Lamp Economy Mode", If your projector has this feature, to lengthen the life of the lamp by reducing its brightness. In most cases you will get a 50% increase in lamp life with a 20% reduction in brightness and you will not likely notice the reduced lumen output.
   
   Allow the projector fan to turn off after you power down and before you unplug the projector. The only exception to this is a projector that is designed to keep the fan turning for a brief period after removing power.

Sharp PG-F325W

Cutting Edge Technology Provides High-Quality Picture

WXGA Compatibility

The 16:9 wide screen aspect ratio is becoming increasingly common for video and computers, and the PG-F320W projector uses wide-screen-compatible WXGA (wide XGA, 1280x800). WXGA provides a viewing area 1:3 times large than standart XGA (1024x768), delivering a wide ficture in full native size. The projector can be used in a variety of applications, such as business meetings with wide-screen computers as well as at schools and stores to display wide-aspect video content. in addition, compatibility with digital high-definition 1080p signals enables using the PG-F320W as a theatre projector.

BrilliantColor Technology

BrilliantColor Technology achieves greater ficture brilliance while providing more superior colour nuances by using a new colour-processing algorithm as well as processing that improves the ficture quality from the system-level colour signal. Brilliance is particularly improved for images with intermediates colours, such as ideo and natural landscapes.

Dust-Resistant Structure Minimizes image Degradation

After a projector has been used for some time, dust particles that have entered the interior accmulate on the oftical components and lower performance. The PTLB78VE prevents this with a unique dust resistant design.This totally redisigned package has touchsensor controls that eliminate the gaps around conventional buttons and a lens cover. The design also incorporates a cover that protects the zoom/focus ring when not in use.these features combine to help reduce dust entry. inside the projector, the airflow is efficiently controlled by a structure that reduces contact between extrnal air and the optical components. This all works together with the high-performance Micro Cut Filter to minimize image degradation.
