LCD vs DLP

The liquid crystal display, known as LCD, works by placing a light bulb inside the TV that produces light. This light is then transferred to millions of crystals, in which an electric flow is used to change colors, and assign the correct color to the screen. The colors are red, green or blue liquid crystals.

One of the advantages of LCD is that it transmits better color saturation. They are brilliant, crediting them as a better entertainment package than DLP. They can be hung on the wall because of their size, which is less than 4 inches deep and less than 50 inches long. LCD screens also offer a finer image than DLP at any resolution. It is also efficient with light, as it commonly creates a remarkably high lumen output from the American National Standards Institute (ANSI), than DLP with the same watt lamp.

LCDs have become popular because they are cheaper and easier to produce. They also offer excellent viewing at angles of up to 60%. Therefore, it allows to see in a large room, where some areas are not directly in front of the television. However, LCDs have a shorter lifespan, usually up to 70,000 to 80,000 hours, or about 28 years of regular viewing. This is due to the crystals, and not to the light source, where the green color will fade, resulting in a red or blue tint.

There is no other option but to change the television. Secondly, it is the black level and the contrast weakness, which are significant in a good video image. And thirdly, it is the door screen effect, due to visible pixilation. It looks like you’re looking behind a screen.

Digital Light Processing, or DLP, uses a small computer chip, digital micromirror device (DMD), with thousands of mirrors in it. The mirrors reflect the light through a color wheel, supported by a bulb that focuses on the mirror, and then on the screen, which is considered a rear projection.

DLPs create a reliable image quality for a longer period of time. It has a light bulb that produces light on the screen and can be replaced. It also provides the largest television of the highest quality, and at a cheaper price, compared to an LCD screen of the same size. DLPs do not have screen door effects like those found in LCDs, and they are used in digital movie theaters. It is a screen with low heat and low power consumption. It has high contrast images due to its fixed pixel screen. However, these pixels are limited. The lifespan of DLP is 80,000 to 100,000 hours, or about 30 years of regular viewing, before the colors fade.

One of the biggest drawbacks of DLPs is the line of color on the screen called rainbow effect, which you see when you look away from the screen and then quickly look back or when you look at the screen from one side to the other. The viewing angle, which is only 40% or less, and its rear projection, makes the colors inconsistent from the other side of the room. The depth, which measures between 6 and 18 inches, prohibits hanging the DLP on the wall.

Summary:

1. LCD has better color saturation than DLP.
2. The LCD screen may hang on the wall because it is 4 “deep and less than 50” long, compared to the 6 “to 18” depth of DLP.
3. The LCD screen has a higher viewing angle, which is up to 60%, compared to 40% of DLP viewing angles.
4. DLP has a longer lifespan of 80,000 to 100,000 hours, or about 30 years of regular viewing, while LCD has 70,000 to 80,000 hours, or about 28 years of regular viewing, before the color fades .
5. DLP is cheaper and higher quality than an LCD screen of the same size.
6. DLP has no screen door effect, but has a rainbow effect.
7. DLP is a screen with low heat and low power consumption.
