Types of projectors differ so choose carefully

If considering purchasing a projector then the first thing to take into consideration is the fact that there are many different types of projector available. The types are split into two different categories, the TUBED types of projectors and the Liquid crystal projection types of projectors.

Of the two types of projectors the Liquid crystal projection is the easiest to use when it comes to the majority of users. While the TUBED types of projectors or CRT as they are also known, offer one of the sharpest and clearest pictures. While these are the two categories associated with the different types of projectors there are also many types for each. First we will take a look at the advantages and disadvantages of both the CRT and the LCP types of projectors.

The CRT without a doubt gives the best picture quality which of course is huge plus in its favor, however the downside to this type is that it is very expensive to purchase and installation has to be done by a professional. Another big disadvantage to this type is that once installed it cannot be moved around, it is usually fixed solid to the floor or mounted on the ceiling.

The Liquid crystal projection can be set-up by the novice and it is portable. It is also very easy to use and the majority of these types of projectors will have features such as zoom. The disadvantages to choosing this type is that when magnified the pixels show up more.

Now let's take a look at the various types of projectors, the type refers to the display of the projector, with the LCD having glass panels and the DLP taking advantage of mirrors. The standard LCD will usually have a single panel of glass which then takes control over the three primary colors. However these types of projectors are not as popular as the LCD made from polysilicon and the DLP models.

The digital light processing or DLP relies on just one single chip, this uses thousands of what are called micro mirrors to take care of the lighting of the lamp to send it through the lens. The majority of these types of projectors will use over 400,000 miniscule mirrors. This is one of the newest types of technology and also one of the most popular types of projectors.

The polysilicon models are a higher quality than the LCD and colors are controlled by three panels. The three panels allow the projection of polysilicon to have a saturation of color which is higher than the LCD, thus resulting in a far better picture.

Again there are pros and cons to the different types of projectors. While the LCD does have vibrant and more vivid colors, the amounts of pixels they have are limited. This means that when the picture is enlarged it is almost like viewing the screen through a fly-screen. Shadow detail is also known to be poor and the blacks on the screen can appear to be washed out, almost a murky grey.

The DLP has excellent contrast and the picture is bright and clear, however black again can be a problem and some who have bought this type of projector have noticed that colors can flash across the screen almost in a rainbow sometimes. Eye soreness after extended watching has also been reported by a few people.
