The Types of Home Projectors Available Today

The main types of projectors available in the market can generally be
divided into two categories; the first type being the home theater and the
second type is the multimedia types. These two types of categories have
different characteristics and usage.

The home theater projectors can be connected to every home audiovisual unit
via digital connection whereas multimedia projectors are widely used in
business and professional industries as the components are built to assist
multimedia presentations. With computer-based resolution, presenting Excel

The current technology is now installed with powerful display systems
namely Liquid Crystal Display (LCD), Digital Light Processing (DLP) and
Liquid Crystal on Silicone (LCoS) types of digital beamers. The LCD-based
projectors’ optical device consists of three LCD display panels for 3 three
primary RGB colors, which enable the device to project full-color images on
to the screen. The reasons most people opt for LCD types are because of the
affordability, sharper image display and great color saturation. However,
the LCD projectors are prone to display the screen door effect and could
accumulate dust blob trapped on the panel. Furthermore, the size of LCD
projectors is quite bulky compared to the other types.

Meanwhile, the DLP projectors use a single monochrome DLP chip and
generating colors with the spinning of the color filter wheel, including
primary colors on to the screen. The DLP projector is quite similar to its
LCD counterpart but it displays deeper black and smoother images albeit
with higher contrast and brightness. However, the DLP type could also
produce rainbow streaks during display and the entry and midrange
projectors have less flexible lens setup.

The latest technology is the Liquid Crystal on Silicone (LCoS ), which is
an implementation of the DLP and LCD projector technology. LCoS is an
innovative technology that is normally applied in television projection
called “micro-display” technology. The LCoS projectors applied the same
idea of DLP projectors but instead of using reflective lights, LCoS
projectors use liquid crystal to replace the individual mirrors. Other than
the high retail price and bulky physical, the LCos projectors have many
great features to offer consumers including a higher resolution and
smoother image display as well as color saturation to die for. Since LCoS
projectors are new in the market, at the time being, consumers’ options are
limited to only a few designs.
