This optimal position is directly along the central axis of the TV with the central point of the screen at eye level. Viewers seated in any other position come to experience degradations in picture quality ranging anywhere from minor to severe, the most notable being trapezoidal distortion. The claim that curved screens provide a wider field view is disputed, by another claim that a substantial offset from the center provides greater viewing distortion than that of a flat screen. However, the equidistant claim by manufacturers of the various parts of the screen from a centered view is supported. Curved screens and multi-screens have applications in gaming. This variance in the distance traveled results in a distortion phenomenon known as the pincushion effect, where the image at the left and right edges of the screen becomes bowed inwards and stretched vertically, making the entire image appear blurry. A standard IMAX screen is 22m wide and 16m tall, but there are screens with even larger dimensions. ![]() To drive the solution, LG electronics has developed Infrared-based touch solutions for the curved display. Countless 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. Curved 21:9 monitors were then developed to address this issue and provide a distortion-free, wide-angle viewing environment. ![]() Since the introduction of flexible glass, liquid crystal displays (LCDs) can be applied to curved surfaces without bending existing panels. The screen technologies used to create curved LCD screens are Vertical Alignment, which helps to reduce any white glow that may affect an angular view, and IPS Panels, which are more susceptible to distortion.
