Apart from your regular TV, one other piece of technology that has proven to be one of the best in terms of viewing your multimedia content at home, colleges, and so on is a projector. Over the years, there has been an advancement in technology and innovations of projectors with many kinds of projectors out there
You might be quite interested in using or choosing a projector, however, you seem to be in state of dilemma over which ones to choose – is it going to be an LCD projector or a DLP projector which are the two most commonly used ones, which one better suits your goals and so on. Don’t fret!
For this reason, this article will show you all you need to know. Enjoy!

What is an LCD Projector?
An LCD projector is a kind of projector that uses liquid crystal display technology to view high-quality pictures over a series of processes. It is best known to display pictures on a screen or flat surface.
Breakdown – How does LCD projector work?
In case you are wondering about the magic behind the LCD projector, how the white light generated by the lamp turns your favourite movie into series of images, then you are in for a ride!
The LCD projector works by using high-intensity light beams from a lamp that move through numerous shifting pixels. The flowing white light hits a reflection.
The first reflector is made to reflect only red light while other colors in the white light pass through it. In the same process, the second and third reflectors reflect green and blue respectively.
The projector always reflect light at a 45 degree angle, therefore, there are some reflectors often called the “front silvered” that help to keep this in check. The reflective surface is kept in front, unlike other mirrors whereby the reflective surface is at the back. Once, the projector can eliminate the bend created by the three primary colours using the front silvered, it is then focused.
It is commonly seen that light scatters especially when treated as a wave, however, the projector needs to focus the light in only one particular direction, therefore, it has a polarizer and 3 focusing lenses that can set the wavy light straight. The three focusing lenses also as a filter that helps the projector to give only the color it wants.
To the most anticipated stage, which is the imaging stage, the three primary colours (Red, Green, and Blue) produced are combined in various amounts to giving any colour in the light spectrum within the colour wheel and LCD projectors are capable of producing over 15 million colour combination.
This is made possible with the help of liquid crystal display technology. In its basic form, the liquid crystal display has lots of slats. Think of it like when the projector needs more red color, the liquid crystal display just opens those slats on the red.
In the real sense, there are three crystal units each for the primary colors that are glued to one face of a special kind of prism. Then a lens allows you to easy focus, zoom the image whenever you are projecting.
Why you should choose an LCD Projector.
LCD projectors are quite important for presenting colorful electronic presentations. This is because they have good image quality, you can display computer and video images with an LCD projector.
Talking about the image quality, we are mostly conditioned to seeing bright clear, and colorful movies, so, LCD projectors have high ambient light and can produce more saturated images
Pros of LCD Projector
Below are some of the advantages of LCD Projector
- They use fixed crystals, no movement and hence reduce the noise level
- It gives higher light saturation
- It has high ambient light conditions
- It utilizes lesser power
- It has a lower heat level
- There is no rainbow effect
Cons of LCD projector
- They need constraint filter maintenance
- Image pixelation is more visible
- They are not portable
- Screen door effect
What is a DLP Projector?
DLP projector also known as Digital Light Processing Projector is a chip that utilizes micro-mirror devices called Digital Micromirror Device (DMD) of fixed resolutions onto a silicon wafer.
DLP projector could use color wheels (single-chip projector) or a prism (three-chip projector) to reflect light on a pixel-by-pixel basis. It is commonly found in video projectors.
How the DLP Projector Works?
The chips of the DLP projector m lions of microscopic mirrors present on the surface. There are two types of technologies involved in DLP projectors. The first is called the one-chip DLP projector.
The one-chip DLP projector creates an image using pixels directed toward or away from the light source thousands of times per second. It uses a mirror to reflect light, when the mirror is switched on, light gray color is reflected. It has a color wheel that filters the light into red, green, and blue. The single-chip used in this projector can produce up to 16 million colors.
The second type of DLP projector is the three-chip DLP. Here, the colour wheel does not filter the light but it allows the white light produced by the lamp to pass through a prism. The prism separates the white light into the three primary colours (Red, Green, and Blue).
Each chip in this projector handles a particular primary color. Therefore, the color reflected by the mirrors present on the chip is combined and then projected to the lens where an image is finally formed. The three-chip DLP can produce up to trillions of colors, hence a much larger grayscale.
Why should you choose a DLP Projector
If you want a more digitalized projector, the DLP projector can be your best shot. It is commonly found in home theaters and other applications. It has lots of external peripherals such as external speakers, it can connect to two to three smartphones, tablets, and so on.
DLP projector is also known for its high contrast when it comes to high-quality movies. In case you don’t want an expensive projector, a DLP projector is reasonably priced.
Advantages of DLP Projector
- Item 1
- Item 2
- Item 3
Cons of DLP Projector
- It exhibits the rainbow effect
- It produces noise
LCD vs DLP Projectors: a side-by-side comparison
There is no doubt about having the best projector suited for your particular needs. For your particular needs, we have compiled a list of features ranging from image quality to lamp life that will show you how you can select your projector at a glance. Check the table below.

How should you choose the right projector for yourself?
Now that you have gone through the reviews of each type of projector, you are left with the option of choosing one. There are some factors you need to consider before you purchase the best projector for you.
These factors will help solve any challenges in choosing the right projector. Below are some factors you should be put into consideration
- Room size – The first thing you need to consider before getting a projector is the room size. Depending on what size screen you want, you may not have enough spaces to project a certain distance from the screen. This distance is called throw ratio
- Projector Type – Now consider which type of projector you want, is it an LCD or DLP. What is your preference, what are the features and benefits, what purpose do you need them for, is it gaming, movies, or just PowerPoint presentation? All these questions will help you to choose the right projector
- Brightness – Movies do have high brightness, so it is understandable if you want to get such brightness from a projector
- Budget – Your budget is also another factor to consider. Is the type of projector you want costly or reasonably priced?
It is clear that LCD Projectors are quite better than the DLP projectors from the comparison chart. They have features such as sharp Image quality, brightness, color, saturation, resolution, and so on that have a great benefit when you are viewing your multimedia content.
Although, DLP projectors are also good in their own right. They are quite portable, digitalized, and give high contrast pictures. However, your goals, preferences, and factors are to be considered before you finally make your purchase. In our final thoughts, we implore you to make that purchase now and enjoy your projector while it lasts. Ciao!
