LCD vs Projector
Electronics experts have been carrying out a debate for years between liquid crystal display (LCD) TVs and digital light processing (DLP) or projection TVs. Both TV technologies use projectors to convert signals from broadcast and cable networks into images. LCD TVs use a trio of glass panels to represent the primary colors with light passing through each panel. As the light is projected to the LCD screen, individual pixels and subpixels are modified to create the right lines and colors. A DLP TV uses a single chip with reflective mirrors to create primary and secondary colors rather than using color filters.
The LCD vs. Projector debate must start by looking at the virtues of both technologies. LCD proponents are quick to point out the improvements in image quality compared to DLP TVs. Experts often cite benefits like sharper images and fuller color when highlighting the positive aspects of LCD technology. Consumers who want to reduce their electrical bills and save energy are drawn to LCD’s use of efficient lighting. The DLP side of the LCD vs. Projector debate brings out advantages like smaller set sizes and contrast improvements to counter pro-LCD arguments. DLP advocates are quick to point to the diminutive packaging of TV sets that use color chips rather than sizable color panels. The color contrast on a typical DLP set is much lower than the contrast on an LCD set, creating a brighter image.
Consumers should also look at the weaknesses revealed in the LCD vs. Projector debate. LCD technology has come under fire in recent years for a general decrease in image quality over time. Consumers have complained that LCD TVs have pixels visible with the naked eye, thereby distracting viewers who are looking at individual colors rather than entire pictures. Another criticism of LCD TVs is the reduction of image quality due to uneven wear on the color panels over time. The primary criticism of DLP technology in the LCD vs. Projector debate is the use of a mirrored color wheel within the chip to shift colors before images are projected. DLP critics point out that this technology can sometimes create monochromatic images with red, blue, or green dominating the image if the wheel is not calibrated correctly.
In terms of what to get for yourself, you should think not only about the technical parameters but also about the size that you need, if you are not looking to build a Cinema in your living room, you will probably go for an LCD TV rather than for a Projector.
The main benefit of getting a Projector is that you can get a huge picture (for instance 110 Inch wide) for less than a 47 or a 52 Inch LCD.
Buying a projector also means that you will need to leave a lot of space on the wall, unless you’ll decide to get a Projector screen which can be taken off in any moment.
