The Advantages and Disadvantages of LCD Projector Hire
A projector is a vital piece of electronic equipment which is required for all types of presentations, conferences, seminars etc.
A projector is a vital piece of electronic
equipment which is required for all types of presentations, conferences,
seminars etc. It is “part-and-parcel” for business management. Projectors can
be categorised into two technologies:
DLP – Digital Light Processing
LCD – Liquid Crystal Display
The two different types refer to the
internal systems that the projector uses to compose an image. The LCD systems
have improved drastically over the couple of years while the DLP models are
more competitively priced. LCD and DLP still have unique advantages when
compared with each other. However, both technologies are good in quality,
offering clear and vibrant images, and it is up to every individual to decide
which technology is best based on specific requirements such as brightness,
resolution, contrast and connectivity.
The LCD Projector Hire is common amongst
the corporate sector for all their business meetings, seminars, workshops etc. The
projector is used by many manufacturers such as Epson,
The LCD contains three separate glass
panels – one for red, green and blue components of the image that is being
transferred to the projector. As the light passes through the panels,
individual pixels can be opened to allow light to pass or closed to block the
light. This action modulates the light and produces the image that is projected
onto the screen. Thus is it known as 3LCD.
few Advantages on LCD Projector Hire:
- LCD is generally more ‘light efficient’ than the DLP. For
example, if you use a lamp of the same wattage in both an LCD and DLP, the
LCD will produce a brighter image.
- With 3LCD projectors you will get a beautiful colour in clear,
defined images – even in a bright room. You will also have more than
double the brightness in colour luminance, compared to non-3LCD
projectors. This projector is also capable of projecting bright, vivid
images with a low output lamp.
- Considering the above mentioned system in the LCD projector,
and when compared with DLP, many people would prefer the LCD for the
exclusive brightness feature.
- LCD produces a sharper image (more precisely focussed).
Disadvantage on LCD Projector Hire:
- It has a chicken wire effect causing the image to look as
though it is heavy with pixels. However, with the recent technology
development of 3LCD, this disadvantage is hardly noticed.
- It is bulky due to the
many internal components it carries, making it slightly inconvenient for
- ‘Dead Pixels’ – they can become permanently on or permanently
off. This is barely noticeable with one dead pixel. However, if the
projector develops a great number of dead pixels, this can be a hindrance
to the projector.
- LCD can fail fast and replacements are very expensive. DLP
chips can also fail, but since this system has fewer parts, failure in a
DLP projector is relatively rare.
LCD Projector Hire is seen as more popular
as the colour reproduction is critical and this machine has it as its best. The
DLP projectors are also working towards obtaining better colour accuracy, so
that they too could provide their services to the corporate sector.
