• LCD (Liquid Crystal Display) projectors: Use liquid crystal layers to display images, providing high resolution, true-to-life colors, and sharp images.
• LED (Light Emitting Diode) projectors: Use LED lights for projection, offering long lifespan, energy efficiency, and fast startup.
• 3D projectors: Enable direct 3D projection without 3D glasses, creating immersive depth effects for presentations, entertainment, and 3D gaming.
• Ultra-short throw projectors: Can project from a short distance, saving space and avoiding obstruction of the light path.
• Portable projectors: Compact and easy to carry, suitable for mobile presentations or small spaces.
• Multifunction projectors: Combine projection with features such as built-in speakers, wireless connectivity, and smart functionalities.

2. Overview of Workplace Environmental Monitoring Services

a. What is workplace environmental monitoring for projector manufacturing factories?

Workplace environmental monitoring (or occupational environment measurement) in a projector manufacturing factory involves collecting, evaluating, and analyzing indicators of workplace environmental factors to implement timely measures, minimize environmental harm to workers’ health, and prevent occupational diseases. Monitoring is legally required for projector manufacturing factories.

Workplace environmental monitoring is crucial for protecting, caring for, and enhancing the health of employees, as they are the main resource of a business and directly contribute to its profit. Employees frequently exposed to hazardous factors beyond permissible limits may suffer health impacts and develop occupational diseases.
