So there it is. Confirmation of the fading consumer interest in FM and CD.

The least expensive video projection system with a laser light source is from Epson.

The most expensive digital projection systems with a laser light source are, of course, in movie theaters. I lost track of this link to a story that I meant to post ages ago. When the Covid pandemic hit, Sony decided to abandon the market, rather than pursue lasers as a light source.

Sony’s home projectors were also affected by the problem of UV light damaging imaging devices. The technology is called LCoS. It’s an LCD variant where light doesn’t pass through the panel, it’s reflected.

UV comes with the visible light from the UHP lamps found in every video projector before LED’s and lasers. When first reading about this problem I panicked, because my JVC projector uses LCoS. JVC issued a statement that their proprietary LCoS panels are not affected. Whew!

After ten years, my JVC DLA-HD750 is halfway through the lifespan of its third 2,000-hour UHP lamp, and I continue to be impressed with the image quality.
