Curved screen

[9] Manufacturers suggest that curved screens allow greater range in satisfactory viewing angles and offer minimal trapezoidal distortion in comparison to flat-screens.

[citation needed] Backward curved screens have the potential to be used as digital signage that can be installed at various locations to produce marketing exposure.

[9] Curved screens are also widely used in IMAX and standard movie theaters for their ability to produce natural expressions and draw the audience deeper into the scene.

[11] In about 2009, NEC/Alienware together with Ostendo Technologies, Inc. (based in Carlsbad, CA) were offering a curved (concave) 43-inch (110 cm) monitor that allows better viewing angles near the edges, covering 75% of peripheral vision in the horizontal direction.

This monitor had 2880x900 resolution, 4 DLP rear projection systems with LED light sources and was marketed as suitable both for gaming and office work, while for $6499 it was rather expensive.

Multiple theaters, including the Cinerama Dome in Hollywood began to use horizontally curved screens to counter image distortions associated with super-wide formats such as 23:9 CinemaScope.

Since the introduction of flexible glass, liquid crystal displays (LCDs) can be applied to curved surfaces without bending existing panels.
