Laser and LED projectors are two popular types of projectors that are widely used in a variety of applications, such as classrooms, meeting rooms, home theaters, and other presentation venues.

If you are in a hurry: Laser projectors produce images using lasers, while LED projectors produce images using light-emitting diodes (LEDs). The main difference between these two types of projectors is the light source used to create the image.

Below in the article, we will analyze in more detail how each of the projectors works, what their pros and cons are.

How Does a Laser Projector Work?

Instead of relying on conventional lights to create visuals, laser projectors utilize lasers as their primary source of illumination and cast vibrant, life-like hues with an unprecedented accuracy in color representation. In essence, it works similarly to traditional projectors by dispersing light through image or video sources and displaying them on any given setting.

Leveraging the power of lasers, a laser projector is able to create vivid and detailed visuals projected onto surfaces. Lasers are directed towards mirrors that reflect back onto a DMD or LCOS chip, which contains mini-mirrors capable of adjusting in order to direct light accurately into different directions - thus forming an image on any given surface.

Laser projectors use powerful diode lasers that radiate visible light at specific wavelengths. The lasers are usually divided into red, green and blue colors of lights to direct each hue onto the right mirror in a DMD or LCOS chip.

By manipulating the intensity of lasers and adjusting mirrors within the Digital Mirror Device or Liquid Crystal on Silicon chip, it is possible to create a laser light show with vivid colors and brightness. This focused beam passes through an optic lens onto any surface to display an image in all its glory.

With a laser projector, you can enjoy the benefit of long-term savings with its extended lifespan. These projectors come equipped with either one or three lasers which allow them to produce high brightness levels and consistent colors for an optimal viewing experience over time. Furthermore, they are capable of projecting RGB images in vivid detail due to their unique design.

Pros and Cons of Laser Projectors


  • High brightness: Laser projectors can produce high levels of brightness, which is important for use in bright rooms or outdoor settings.
    Longer lifespan: Lasers have a longer lifespan than traditional lamps used in projectors, which can result in lower maintenance costs over time.
  • Consistent color accuracy: Laser projectors offer consistent color accuracy over the life of the projector, which is important for applications such as digital cinema and medical imaging.
  • Quick start-up time: Laser projectors have a quick start-up time and can be turned on and off instantly, unlike traditional lamp-based projectors that require a cool-down period.


  • Higher cost: Laser projectors are generally more expensive than LED projectors.
  • More complex design: Laser projectors require a more complex design than traditional lamp-based projectors, which can make them more difficult to repair if something goes wrong.

How Does a LED Projector Work?

An LED-based projector uses LEDs as the light source, which is then directed through a video or image and projected onto a screen. Just like traditional projectors, this method of projection creates clear images on any surface - making it perfect for viewing movies, playing video games or presenting slideshows at home or in the office.

By using an LED projector, the light produced by LEDs is focused and reflected onto a set of mirrors. This then directs it to either a DMD (digital micromirror device) or LCD (liquid crystal display) chip. Containing millions of minuscule pixels that can be individually managed to permit light flow or obstruction, this creates the image you want!

LED projectors are typically constructed with distinct arrays for each of the three primary colors; red, green and blue. To generate their unique hues, every individual LED emits light at a specific wavelength.

Illuminated by brilliantly-hued LEDs, the projected light passes through a lens and is displayed as an image. We can adjust the luminosity and chromaticity of this scene simply by regulating the intensity of each LED array.

LED projectors offer countless advantages, from their environmentally-friendly operation to reduced operating costs over the long term. What's more, since they generate less heat than traditional lamps, LED projectors can be utilized in smaller rooms and restricted spaces with ease.

LED projectors offer lower brightness than laser ones, it can be a drawback in spaces with high levels of illumination or outdoors. Moreover, even if the color accuracy is great at first, it tends to decrease over time and affects its ability to reproduce shades accurately for extended periods of time.

Pros and Cons of LED Projectors


  • Longer lifespan: LED projectors also have a longer lifespan than traditional lamps, resulting in lower maintenance costs over time.
  • Energy efficient: LED projectors are more energy-efficient than traditional lamp-based projectors, which can result in lower operating costs over time.
  • Lower heat output: LED projectors produce less heat than traditional lamp-based projectors, which can make them more suitable for use in smaller rooms or confined spaces.
  • Lower cost: LED projectors are generally less expensive than laser projectors.


  • Lower brightness: LED projectors generally have lower brightness levels than laser projectors, which can be a disadvantage in bright rooms or outdoor settings.
  • Color accuracy: The color accuracy of LED projectors can decrease over time, which can result in less accurate color reproduction in the long term.
  • Limited color gamut: LED projectors typically have a more limited color gamut than laser projectors, which can result in less accurate color reproduction.

FAQs about which is better LED or Laser projector
