What Type Of HD Projector Should You Choose
With the wide range to choose your HD projector from on the market today making the best and most informed decision can indeed be trying. Other articles on this site have looked at the dimensions of your prospective HD projector. The weight of your projector. In addition you have read that you need to consider whether the brightness of the lamp will be sufficient for the room in which you intend to set up your home cinema. There are a number of other factors that you should consider and we will address these in subsequent posts, however this post is going to concentrate on what type of HD projector you should be choosing.
It may not be something you were aware of but the typical HD projector for many years was only available in LCD form. LCD stands for liquid crystal display. LCD displays have been used with great success in computer and home entertainment equipment for a number of years now. In fact such has been the success of LCD displays, and perhaps more importantly the reduction in the cost of manufacture of LCD screens that LCD technology has become pervasive, including our everyday HD projector. One problem with LCD HD projectors was that light from the lamp needed to be filtered through a red, blue and yellow LCD panels to produce the full colour projected image. This requirement resulted in the necessity to have three separate colour panels and this meant that the HD projector case needed to be larger to cope both with the panels and the additional electrical wiring that also required accommodation.
As with all things, technology waits for no man and an innovative company in the US call Texas Instruments attacked the problem and appear to have solved it with the of DLP technology. In a DLP technology HD projector the light from the lamp is converted immediately to a picture before it is projected. As a result a great deal of space is saved within the HD projector case allowing HD projectors to be smaller, more compact and lighter. This is great news, however there remains a small niggle. The accuracy of the DLP picture is not as good as that of the LCD picture. Is this important? Does it significantly impair the DLP HD projector. This is an answer only you can give, but generally speaking in a small home cinema set up high colour accuracy is unlikely to be a major problem and therefore I personally do not see it as a big deal.
