DLP or LCD?
There are two common technologies and two rarer technologies used in home cinema projectors. The common ones are DLP (digital light processing) and LCD (liquid crystal display), the rarer CRT (cathode ray tube) and LCOS (liquid crystal on silicon) which are used on higher end projectors. Traditionally LCD’s strengths are in colour saturation and accuracy, efficiency and image sharpness. The better saturation gives a richer more vibrant look to the picture and colours are rendered more accurately. The better light efficiency means that for a gives lamp wattage, LCD projectors will tend to give more light than dlp. Image sharpness is near perfect with LCD (like the difference between and lcd monitor and a normal CRT monitor) whereas DLP has a slightly softer focus. LCD’s weakness lies in two area’s. The most commented on is the “screendoor” or “chicken wire” effect whereby you can see the pixel structure. In modern LCD video projectors this is much reduced by using higher resolutions and
