Concave & Convex Video Display Technologies

(1/2) > >>

jonovid:
what happened to curved TV's
will we see retro convex video displays for arcade game cabinets?
as CRT display technologies became unavailable.

Gyro:
They were a sales gimmick, as were 3D TVs - I remember the hassle of getting that one into the HDMI spec for the manufacturers.

There might be a slight argument for concave PC monitors but the 'focal point' of the concave TVs was far too close to be anything more than a gimmick.

As for convex displays, you're never going to see them. The possibilities of producing an LCD or OLED that is curved in two axes simultaneously is non-existent, especially if it's just for a retro CRT look.

tom66:
Curved TVs were just a silly fad,  much like curved phones - turns out people don't really care for them.  I can see some benefit for curved monitors because in theory you could have an ultrawide screen with less physical area used for the same screen size, but it doesn't offer much of an advantage over two monitors next to each other so... meh.

Virtually all OLED screens can be made curved if required, however some can only flex in one axis.

You can emulate the CRT look in hardware or software:

Curved monitors are common and generally recommended for gaming once you go over ~32" or so.

If you want curves get a projector, cinerama has been around for at least 75 years
