OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors.
The screen may also include a crossbar for added strength. Fiberglass screen material is typically available in 30 m (100 ft) rolls in varying widths, from 46 to 305 cm (18 to 120 in) wide. Aluminum screen material is available in 30 m (100 ft) rolls except the range of available widths is less than for the more commonly used fiberglass.

The screens are made by layering stacks of semi-conductor materials and metals between pliable plastic sheets. The stacks need to be perfectly aligned and stay that way. Alignment proves difficult during manufacturing when heat during manufacturing can deform the materials and when the resulting screen also needs to remain flexible.
Electroluminescent (EL) displays have been a niche format and are rarely used nowadays. Some uses have included the Apollo Guidance Computer 7-segment numerical displays, to indicate speed and altitude at the front of the Concorde, and as floor indicators on Otis Elevators from around 1989 to 2007, [7] mostly only available to high-rise buildings and modernizations.
A grey screen may thus succeed almost as well in delivering a bright-looking image, or fail to do so in other circumstances. Compared to a white screen, a grey screen reflects less light to the room and less light from the room, making it increasingly effective in dealing with the light originating from the projector. Ambient light originating ...
Many are made from black or other darkly colored, light-absorbing material (In North America, for example, heavyweight velour is the current industry standard [1]). Theater drapes represent a portion of any production's soft goods , a category comprising any non-wardrobe, cloth-based element of the stage or scenery. [ 2 ]
