If you are looking for a projector but are not sure which one would be the best for your situation, both LCD projectors and overhead projectors are great options.
An LCD (liquid crystal display) projector is a relatively new form of projector. It uses advanced liquid crystal panel technology to produce and project images in a range of color and motion.
Overhead projectors are earlier models of the projector. They display an image from a clear film that rests on top of the projector.

Similarities
Both LCD projectors and overhead projectors achieve the same basic goal. They use light to project an image onto a screen or a wall.
They have some similar internal components as well. They both have strong lamps to project a light-based image, and have various fans and cooling mechanisms to keep them running well.
You could use both of these kinds of projectors to display images and presentations, and both are still in use today. With both of these projectors, you will be able to lead a meeting, presentation, lesson, or lecture.
Differences
LCD projectors and overhead projectors have more differences than they have similarities.
An LCD projector is able to project a more complex image because of its advanced technology, in comparison to overhead projectors. They can display moving images and images that are in color, and can receive input from other electronic devices.
Overhead projectors are a lot more basic in their design, and have been around for much longer than LCD projectors. An overhead projector is limited to projecting only what a person might write or draw on the clear piece of film that rests on top of the projector.
Unlike an LCD projector, overhead projectors are not able to project in color. They can only project a black and white image.

LCD projectors can be used in a variety of different situations because of their advanced technology.
On an LCD projector, you can give basic presentations with still slides and images. You could also project moving graphics, videos, and movies on an LCD projector.
They can be used to display a screen in real time, and have a variety of uses that are not necessarily tied to professional business meetings or lectures.
With an LCD projector, you would be able to display anything that you needed to be off of a computer. This is great for almost any situation, and you have a lot of control over what you are able to do when you are using an LCD projector.
They produce a very clear image, and once you turn the projector on all you need to do is manage what’s on the screen from a different device.
When using an LCD projector, you can have an entire presentation already done, and you do not need to do the extra work of writing it down again.
Cons of LCD Projectors
On occasion, advanced technology might not actually be a benefit. LCD projectors require an input to work, so you cannot use an LCD projector without also having a computer, phone, or other devices to send the image to the projector.
Without other technology, LCD projectors are useless. This also leaves more room for technology failures because you have to count on two machines to be in working condition to be able to properly use an LCD projector.

Pros of Overhead Projectors

Overhead projectors are very reliable. They use minimal technology, compared to more modern versions of projectors.
They’re great for classrooms and lectures, but they could also be used in any other situation. Essentially, they replicate a blackboard or a whiteboard, but they can be used while sitting down, which makes them a great option for those who can’t stand, or who require breaks from standing.
When you’re using an overhead projector, you are able to write what you want to. This is great for teaching purposes, and it is much easier to write on than a horizontal board.
Overhead projectors also tend to be easier to read, as they project a larger image compared to a blackboard or a whiteboard.
Cons of Overhead Projectors
There are a lot of limitations when you are using an overhead projector.
Overhead projectors do not take input from other devices. That means that you can’t use your phone, computer, or anything else to project an image through an overhead projector.
They are only able to display images that have been handwritten on a clear plastic film placed on top of the projector.
Their displays can only be in black and white because of the way that they project an image. When you place the film on the projector, it takes the marks from what you write and displays them on the wall, so it can’t pick up color.
Essentially, when you use an overhead projector, you are very limited in what you can display, and what you can do with it. Overhead projectors are not really good to use for entertainment, and are mostly good for professional or learning purposes.

Which Is Better?
Overall, there are more benefits to using an LCD projector. They are a lot more versatile than overhead projectors, and they can be used for many different situations.
Overhead projectors are better in a limited number of situations. They are great for simple classroom use, and to display writing in real time.
However, LCD projectors are more versatile than overhead projectors. If you are looking for a projector that you can use for many different purposes, you should go with an LCD projector.
While LCD projectors are more expensive than overhead projectors, if you are going to use all of its capabilities, it will be worth the price.
However, if all you need to use a projector for is a simple display of writing, buying an overhead projector is a good way of saving money. It will be convenient for what you need, and it will work great even though it’s an older model of the projector.
