Projector Reviews: What’s New In Technology


There are two different types of projector technologies available:  DLP and LCD.  Each of these technologies is different and which one you choose will have a bearing on how you operate them.  An LCD projector is able to display an image that is much brighter than a DLP projector.  At the same time an LCD projector will be limited to the length of time you can use it due to its transmissive design.  The DLP projector has an engine design that uses reflection to create the picture from many thousands of small mirrors.  This means that heat from the projector lamp won’t have an impact on any of the components within the projector.  You can operate a DLP projector without interruption or any loss in the way the projector performs.  The only performance loss you might notice is when the bulb in the lamp burns out over a period of time.  This can lead to a slight reduction in the brightness of the image.  For most projectors you can simply replace the bulb at which time the DLP will start to perform at its optimum.

On the flip side the LCD projector can only be used for about 8 to 10 hours each day.  If you operate the projector for longer than 10 hours the picture will start to deteriorate without returning to its former state.  In an LCD projector the light will pass through the chips in the LCD and then on through the optics to display on the screen.  The heat that comes from the projector lamp will transfer to the LCD chips.  This means that the LCD chip will start to decay as the heat starts to build up from continuous use.  This will affect the way the image is displayed on the screen by altering the colors, warping the contrast, and lowering the quality of the picture.  The bottom line of having an LCD projector is that you have to expect that the continuous heat source will bend the surface of the LCD so that eventually you’re left with an “etching” effect.  This can cause permanent damage to your projector.

Making the choice between and LCD projector or a DLP projector will depend on how long you want to use it and how much you want to spend.  Expect to pay much more for DLP projectors.  The LCD projector is a good choice for families who want to upgrade from a simple projector and who don’t have the immediate budget to afford a higher quality projector.
