Choosing a type of projector is a hard choice. There are many types with different features that can affect your decision. You might want to think about how clear the picture will be on the screen – which is measured by megapixels.

The more megapixels, the more apparent it will be. If you have different projectors, you might want to think about how bright images will be and how dark they can get without being too much – this is called contrast ratio.

In this case, DLP-type projectors have a better contrast ratio than LCD-type projectors, so they may work better for you if you need primarily bright or dark images on your screen at once.

There are three leading technologies: DLPLCD (or tri-LCD), and LCOS (also called SXRD or D-ILA).

In the case of LED or LASER projectors, the acronym refers to the lamp technology.

Projection Technology and lamp Type
A projector, like a lamp, needs an energy source. As a result, it is defined by the technology utilized in projectors and the light-source technology. The term “lumen” refers to units of light energy emitted from an LED or laser light source (used in DLP or LCD projectors).

Types Of Projectors: DLP, LCD, LCOS

The technologies are developing, but some still have drawbacks. For example, the lens quality and size of yesterday’s technology have been reduced through technological improvements to fit our needs better today. 

However, there is also a difference when looking at the design features or projection surfaces used in screens.

The features indicated below are general. There are indeed models of all qualities (prices ranging from 200$ to over 2000$).


Developed by Texas Instruments, DLP (Digital Light Processing) is the oldest and most widespread projection type. This technology has been around for a long time, and it still helps to provide projects with quality images. The price is affordable too.

  • Image quality: sharpness, natural colors, good contrast, and deep blacks.
  • Quality/price ratio.
  • Rainbow effect potential: rainbow effect, see below.
  • Noise: some models are slightly noisy.

In most cases, LED projectors also use DLP technology.


We should talk about tri-LCD because that is the kind of model you will find if you buy one. You can find it with Sony or Epson brands, but they are less common than DLP projectors.

  • Image quality for high-end Epson models
  • No rainbow effect
  • Lower contrast, except high-end models
  • Price: Qualitative home theater models are relatively expensive.

Nowadays, you can see the “grid effect” on screens because of the spaces between pixels. It’s not a disadvantage anymore.


LCOS (Liquid Crystal On Silicon) technology combines the best of DLP and LCD., which may use different names for the same thing. For example, JVC calls it D-ILA, and Sony calls it SXRD. LCOS is a technology that provides good images for home theaters, but the price is high at around 2000$.

  • Exceptional image quality: contrast, color, depth of blacks.
  • No rainbow effect.
  • Price: no models below 2000 $.

The brightness in these projectors is not very high. Some models that cost $5000 have a lower brightness than 2000 lumens. They are mainly designed for watching movies, and they’re best in a projection room.

Lamp Technology: UHP, LED, Laser.


Today’s most widely used type of home theater lamp is the UHP (Ultra High Performance) mercury LED. These lamps are bright, and their lifespan ranges between 3000 h to 6000 hours.

But some models indicate 10,000-hour maximum longevity, making them one of your best options if you want quality light without worrying about cost or wastefulness over time like with other types!

A general rule when it comes down to selecting what kind of projector bulb will work well for any particular project isn’t always true in every single situation:


LED projectors are mainly DLP projectors with LED lamps. They are very efficient and work well. But they don’t have as much brightness as other projectors, so they are not suitable for watching movies at home.

However, there is no doubt that future models will always be better.

  • Long lamp life: 5 to 10x greater than conventional mercury lamps (10 to 30,000 hours depending on the lamp).
  • Very compact and light, ideal for mobile use.
  • Brightness: lower than on traditional projectors.

LED projectors are helpful in the professional world because they are compact and last for a long time.


The latest in “lamp” technologies for consumer projectors is the laser. The laser has many advantages, but these devices are still expensive. 

However, this technology will likely improve over time.

  • Very bright projectors: you will find models of 4000 lumens or more.
  • Lamp life: 20 to 30,000 hours on average (5 to 10 times more than standard lamps).
  • High-speed start/stop, no heating or cooling time.
  • Relatively expensive: compared to conventional projectors.
  • Few models available

What To Choose?

Projector technology is not the first thing to consider when choosing your projector. The resolution, brightness, or colorimetry are more critical than projection technology. 

For example, the difference between DLP and LCD is less necessary now than before.

It will depend on how much you have to spend and what you need. Some people need a lot of space. They will want to use the other technology. Other people need a small house for one or two people to use the first technology.

By scope:

  • Professional use: DLP or 3LCD (LED lamp if used on the move).
  • Home theater use: DLP, 3LCD, or ideally LCOS (SXRD, D-ILA).

By budget, for home theater projector use:

  • Less than 1000 $: DLP projectors offer excellent value for money.
  • Between 1000 and 2000 $: the choice will be between DLP and tri-LCD (especially if you are subject to the rainbow effect).
  • Over 2000 $: LCOS models (SXRD, D-ILA) will give you incomparable image quality.


What is the best color for a projector screen?

The best color for a projector is white. White screens reflect light better than any other colors, producing brighter images. If you use a colored screen, you’ll need to adjust the brightness setting on your projector to compensate for the difference between the projected image and the actual screen.

Why do premium projector screens cost so much?

Premium projector’s screen costs are high because they use expensive components such as LCD panels, also used for computer monitors. The price of these screens has been increasing rapidly due to demand from consumers who want to watch movies at home.

Where does a projector’s light originate?

A projector’s light originates from the lamp inside the projector. The lamp has two parts: a filament and a reflector. When electricity passes through the filament, it heats up and glows red hot. 

This heat causes electrons to move around the filament, which creates a current. The current then flows into the reflector, bouncing back and forth between the filament and the mirror until it reaches the end of the filament. 

At this point, the electrons stop moving and emit energy as visible light.

What are projector screens made of?

Projector screens are made from polyester film coated with aluminum oxide particles. The aluminum oxide particles reflect light into the screen, making the image appear brighter.

Where should you put your projector screen in your home theater?

The best place for your projector screen is at eye level. If you want to watch movies from different angles, you need to move the projector up or down.

Is there a downside to using a projector screen?

Using a projector screen is great for presentations, but it has some disadvantages. The most significant disadvantage is that the image quality is lower than a standard TV screen. 

Another problem is that the screen is usually smaller than a regular TV screen, so you cannot fit as much information on the screen at once.

Where will you be putting the projector screen?

The projector screen should be placed at eye level for optimal viewing. If you set the screen too high, you may need to adjust the chair’s height. 

Also, keep in mind that the distance between the screen and the wall should be about 2 feet.

What to know before buying a projector screen?

Before purchasing a projector screen, you should consider the size of the room where you want to place the screen, the resolution of the screen, the brightness of the screen, and how much light the screen will reflect into the room. 

If you plan to use the projector for movies, you may also need to consider whether you want to purchase a screen that has speakers built into it.

What Are the Different Kinds of Projectors?

There are three main types of projectors: LCD, DLP, and CRT. The first two types use light bulbs to create images, while the third uses cathode ray tubes.

All projectors require electricity to operate, which means they need batteries. Most projectors also come with remote control for easy operation.

Can I use a bedsheet as a projector screen?

Yes, you can use a bedsheet as a projection screen. The best way to do this is to cut out a hole in the middle of the sheet, then place a light source behind it. 

It will allow you to project images onto the sheet from any angle.

Which projector type is best?

The best projector for home use is the DLP projector. This type of projector uses digital light processing technology, which allows the image to be projected onto any surface, such as walls, screens, and projectors.

What are the different types of projector screens?

There are three main types of projector screens: LCD, DLP, and LED. The first two types use liquid crystal display technology, while the third uses light-emitting diodes. 

All three types offer excellent picture quality, but they differ in size, price, brightness, contrast ratio, and viewing angle.

Which is better DLP or LCD projector?

The answer depends on what you want to do with the projector. If you need a high-quality image for presentations, go with a DLP projector. However, if you wish to watch movies, go with an LCD projector.

What are projectors and its types?

Projectors are devices used for projecting images onto screens such as TVs, computer monitors, etc. 

There are two main types of projectors: LCD and DLP. The first one uses liquid crystal display technology, while the second uses digital light processing technology.

What is AV projector?

An AV projector is a device used for projecting images onto a screen. The image quality depends on the screen’s size, the projector’s resolution, and the brightness of the light source. Projectors are usually connected to computers via HDMI cables.

How many hours can a projector run continuously?

A projector can run for up to 8 hours at full brightness. However, if you use the projector during the night, you should turn off the light source when the projector is turned off. If you leave the light source on, the bulb may burn out.

Is 3LCD better than DLP?

The answer depends on what you want to achieve. If you need to project large images onto a screen, then DLP is probably the best choice. However, if you need to display small text messages, LCD might be better.

What is a 4K projector?

A 4K projector is a high-definition digital projection system used for large screen presentations. The resolution of these projectors is four times higher than standard HDTVs. They are also much brighter than regular TVs.


Having the correct type of projector for your needs is critical to achieving top-quality results. The last thing you want is a blurry image or one that doesn’t fill up the screen, significantly if it costs so much money!

So before you buy a projector, make sure to research what might work best with your current setup and plans.
