Projectors become a common part of every educational institute, seminar hall, conference room, even the office. Different areas of the room require different types of projectors.
As an example, the cinema hall requires high regulation projector with heavy-duty performance. On the other hand, a simple Pico projector capable to project the seminar in a small classroom of around 15 students.
In the modern age, there are several types of multimedia projectors available now. It is a bit difficult to choose a perfect projector for your areas.
Here we will discuss the different types of projectors and assist you to choose the best projector for your areas.
Types of Projectors
In the world of projection technology, there are four common types of projectors. These are:
- DLP (Digital light processing)
- LCD (Liquid crystal display)
- LCoS (Liquid crystal on Silicon)
- LED and Laser Display
Apart from these, CRT projectors (Cathode Ray Tube) were commonly used in the modern age.
Our team members had completed deep research about these projectors. Here we discuss in detail the different types of multimedia projectors with their advantages and disadvantages.
As we mentioned above, DLP stands Digital Light Processing projector. That uses a million tiny mirror to reflect light towards the screen.
The setup contains a physical color wheel to provide sequential colors. The projector capable to projecting up to 4K video, which is a great opportunity to you.
As well as these DLP projectors available as single-chip and three-chip with green, red and blue DLP chips.
The output light of these DLP projectors is highly suitable for all kinds of environments like a classroom, conference room, or a seminar hall.
Whatever DLP projectors aren’t costly as it offers single-chip versions and a three-chip version. The single-chip models start at under $1000 and the three-chip version starts at around $10,000.
Areas to use DLP projector
- In a business conference room for conducting conferences and delivering a presentation.
- In your home theatres to display the movies, TV programs, and playing video games on a large screen.
- In control and command centers to make a video conference by telecommunications and utility companies.
- In classrooms to present lectures
- In hotels for launch events.
- Fast motion available
- 3D supported
- Adjustable Brightness helps to adjust images brightness
- Sharp lighting makes a clear picture on the screen.
- Blacks colors create a muddy rendering
- Limited placement flexibility
- Sometimes, the Rainbow effect visible on the screen.
LCD projectors stand Liquid crystal Display which is common projectors in the world. It creates images by using multiple elaborate steps to cast the images with three primary colors; green, red, and blue.
These colors are projected simultaneously on the screen to make a completely colored image. LCD projector contains the same Liquid crystal display as televisions and monitors.
There are three mirrors includes on the projector. Each beam of white light passed into three mirrors which are specially shaped to reflect the particular wavelengths of light.
This light will send towards the LCD panel as an electrical signal. The panel will arrange the pixels of the image. After combining the different colored images, it will produce an appropriate image on your projector screen. But they contain less brightness than the DLP projector.
Areas to use an LCD projector
- In a classroom of around 30 students
- Corporate Presentation
- In a home theater
- Tradeshows or exhibitions to present a seminar
- Good Rendering for Black color
- Excellent handling of Motion
- Noisy dynamic iris
- No laser light or LED option available.
LCoS projector is a common projector ion the modern age. The LCoS stands (Liquid crystal on Silicon) projectors that are manufactured with the latest technology.
They can produce the darkest levels and the highest contrast level on the large screen that makes the appropriate images like the original one.
The projector reflects the beam of light into three LCoS panels. Then it will combine the colors and produce the appropriate images with the perfect color combinations.
However, the LCoS projector is unable to provide the same brightness as DLP or LCD projectors and it is an expensive projector for several users.
Areas to use the LCoS screen
- In movie or home theater
- Seminar and conference room
- High contrast ration create an attractive image on the large screen
- It makes images like a film theater
- Dark Blacks
- Noisy 3D
- Blurry fast-motion scenes
- Low maximum brightness
- May it expensive for several users.
LED and Laser Projectors
The LED and Laser projectors are a great choice for those people who don’t want to make a deal of bulb replacing on their projector.
It contains a huge number of LED lights to boast out more light on the screen. These LEDs last for a long time (more than 20,000 hours) than traditional projector bulbs.
There are no color wheels available on the projector cause it replaces and adjusts the red, blue, and green color automatically.
Moreover, it is free from the noise which is created by the color wheel. Plus it is capable to reduce rainbow effect on the screen.
As a result, it makes a great choice to buy a projector with LED and Laser process. The LED and laser projector like Optoma HD91+ starts at around $4000 and it will rise quickly.
Areas to use LED and Laser
- In a home theater
- Conference room to present a seminar
- In a class of more student
- LED last more than 20,000+ hour
- No color Wheel
- Fast to power On and off
- Large color gamut
- Quiet operation
- No rainbow effect
- There is no opportunity to replace the bulb engine whether it eventually dies.
- Lower maximum brightness.
- May it is expensive for you.
Let’s discuss the different kinds of multimedia Projector.
If you want to view your picture slide on a large screen with your family member, the slide projector is one of the great choices for you.
It offers to view photographic slides through optical and mechanical processes. There is a reflector, a bulb, a focusing lens, and a holder included on the projector.
The Slide projector stands in the 1960s to enjoy an entertainment session with family members and friends. Now they become a popular slide show viewer over all the world.
You have to place the photographic slide on the holder. There is a condensing lens to absorb heat from its lights that protect the slide from damage.
Data Projector is a conventional projector in the lecture room and the auditoriums. The device efficiently projects the laptop or PC screen onto the large screen. You can use a supporting wall as a projector screen where it is visible to everyone.
Its VGA output regulation is around 1024 x 768 but you can use 1280 x 1024 and even higher regulation.
Thankfully the data projectors are more compact with cathode ray tubes. It makes lighter than a few years ago. For example, the MP1400 is compact only 4 lbs.
What’s the Native resolution of a Projector
If you are a new one in the world of projectors, you may feel a bit confused by the projector resolution type. There are two types of resolution in a projector. That is called native Resolution and maximum resolution.
All projectors make use of microdisplays. It doesn’t matter whether its brand or type. It is a similar task for LCoS or DLP. The microdisplays have a set number of pixels that we mentioned as Native resolution.
The native resolution is an actual resolution for a projector. It can’t display more than the native Native resolution.
On the other hand, the maximum resolution is a signal format. It has no connection with physical pixels or display regulation.
There are various kinds of maximum resolution in different devices. The highest resolution signal capable to project the particular pixels image on the large screen.
