LCD or DLP Projectors?
The answer is it depends on the application. Here is a list of pros and cons of each system.This is not a definitive list and as technology progresses the pros become greater and the cons are being rectified.
3-Chip DLP Projector, Pros• Perfect colour accuracy.
• Good contrast; much greater than film theatres.
• Good shadow detail.
• Provide the highest brightness of any projector technology.
• Overall image quality deemed as the best of any type of micro display technology.
• Same technology as projectors installed in digital theatres.
• Pure digital technology.
3-Chip DLP Projectors, Cons
• Very expensive compared to the other technologies.
• Generally larger and usually louder fan noise than single chip versions (this is usually because of the lamp required for the brightness).
• Lamps usually don’t last as long (this is usually because of the lamp required for the brightness).
Single Chip DLP Projectors, Pros
• Excellent contrast and shadow detail.
Generally produces reduced noise levels.
• Very little space between each pixel creates a very smooth image even when using lower resolution projectors.Very few, if any, dead pixels. Light engine failures are very rare so repairs are less costly than other technologies.
• Technology doesn’t degrade over time. With proper routine maintenance, DLP projectors consistently provide “just-out-of-the-box” performance. DLP is the only technology that makes this claim.
• Plenty of Full HD 1920×1080 resolution projectors are offered.
Single Chip DLP Projectors, Cons
• Colour separation effect, AKA “rainbow effect” can be apparent on these projectors and can be distracting to watch, although most people don’t notice the effect. Today improvements in technology have improved this significantly.
• Brightness not as high as 3-Chip DLP or LCD machines.
• Due to the colour wheel, Single-Chip DLP projectors are not suitable for filming as banding and flicker will appear on the captured footage.
LCD Projectors, Pros:
• Can be very bright even in home theatre applications.
• True high definition models are the least costly of any technologies.
• Low brightness models will usually have long lasting lamps.
LCD Projectors, Cons:
• Dead pixels can occur and are irreparable.
• Contrast ratios are usually lower than those on DLP projectors.
• Shadow detail and absolute black levels fall short of DLP projectors.
• LCD panels are organic and can deteriorate over time. The less the machine is used each day, the less of a problem this is. Projectors that are used for over eight (8) hours a day can exhibit problems fairly quickly.
• Colour uniformity across the image is lower than that of DLP powered projectors.
• You may notice a “screen door” effect, a grid effect between the pixels when viewing at close distances.
