Answers: How do you build a DIY 4K projector?

• DIY 4K projector build
• Smart phone LCD panel modification
• Collimator and converging lenses
• Heat sink and cooling systems
• Large format camera lenses for projection

What it concludes

• A DIY projector built with a 4K smartphone LCD display and large format lenses delivers image quality comparable to a $2000 commercial cinema projector at a fraction of the cost.
• Using a CPU cooler with an LED light source is ideal for keeping the projector quiet and cool during operation.
• Large format camera lenses are necessary in DIY projectors because their image circles are large enough to cover the entire smartphone screen without vignetting.
