Difference Between LCD and DLP


Liquid Crystal Display, known as LCD, works by putting a bulb inside the television which produces light. This light is then transferred to millions of crystals, in which an electric flow is used to change the colors on and off, assigning the right color onto the screen. The colors are red, green or blue liquid crystals.

One advantage of LCD is it conveys better color saturation. They are bright, crediting them as a better entertainment set than DLP. They can be hung on the wall because of their size, which is less than 4 inches in depth, and less than 50 inches long. LCD’s also give a finer image than DLP at any resolution. It is also light-efficient, because it commonly creates notably high American National Standards Institute (ANSI) lumen output, than does the DLP at the same wattage lamp.

LCD’s have become popular because they are cheaper and simple to produce. They also cater for excellent viewing with angles of up to 60 %. Therefore, it allows viewing in a wide room, wherein some areas are not directly in front of the television. However, LCD’s have a shorter lifespan, usually up to 70,000 to 80,000 hours, or around 28 years of regular viewing. This is due to the crystals, and not with the light source, wherein the green color will fade, resulting in a red or blue tint. There is no other option but to change the TV set. Secondly, is the black level and contrast weakness, which are signi


ficant in good video image. And thirdly, is the screen door effect, because of the visible pixilation. It looks like you’re watching behind a screen.

Digital Light Processing, or DLP, uses a small computer chip, Digital Micromirror Device (DMD), with thousands of mirrors on it. The mirrors reflect the light through a color wheel, with the support of a light bulb that is focused at the mirror, and then onto the screen, which is considered as a rear projection.

DLP’s create a reliable picture quality for a longer length of time. It has a bulb that produces light on the screen, and it can be replaced. It also provides the largest television of the highest quality, and at a cheaper price, when compared to an LCD of the same size. DLP’s have no screen door effects like those found in LCD‘s, and it is used in digital movie theaters. It is a low heat display, and low energy consumption set. It has high contrast images because of its fixed pixel display. However, these pixels are limited. DLP’s life span is 80,000 to 100,000 hours, or around 30 years of regular viewing, before the colors fade.

One of the biggest drawbacks of DLP’s, is the colored streak across the screen called the rainbow effect, which is seen when you look away from the screen then look swiftly back, or when you view the screen from one side to the other side. The viewing angle, which is only 40% or less, and it’s rear projection, make the colors inconsistent from the far off side of the room. The depth, which is 6 to 18 inches, prohibits DLP’s to be hung on the wall.


1. LCD has better color saturation than DLP.
2. LCD could be hung on the wall because of it’s 4″ depth, and less than 50″ length, when compared to DLP’s 6″ to 18″ depth.
3. LCD has a bigger viewing angle, which is up to 60%, when compared to DLP’s 40% viewing angles.
4. DLP has a longer lifespan of 80,000 to 100,000 hours, or around 30 years of regular viewing, while LCD has 70,000 to 80,000 hours, or around 28 years of regular viewing, before the color fades.
5. DLP is cheaper and of a higher quality than a LCD of the same size.
6. DLP has no screen door effect, but it has a rainbow effect.
7. DLP is a low heat display, and low energy consumption set.
