Laser Projectors

Laser projectors use a laser to project images onto a surface. These projectors are small, portable, and energy-efficient. Here’s how to use a laser projector:

• Connect the laser projector to a device using a USB cable or a wireless connection.
• Use software to display images on the laser projector.
• Adjust the focus and brightness of the laser projector to ensure a clear image.

Holographic Displays

Holographic displays use lasers and glass to create 3D images. These displays can be used to project images without a projector. Here’s how:

• Connect the holographic display to a device using a USB cable or a wireless connection.
• Use software to display images on the holographic display.
• Adjust the focus and brightness of the holographic display to ensure a clear image.
