Abstract: The present invention refers to a display device of a general spherical display surface, which comprises a general spherical body that is spherical or hemispherical or any form in between, a layer of displaying film covering substantially the whole surface of the body, and an electronic driver circuitry which is connected to the layer of displaying film for powering and driving the displaying film. The layer of displaying films is thin and cut, for instance, in a plurality of pieces in banana shape, half banana shape, hexagonal shape, diamond shape, triangle shape, soccer ball, or even in sphere or hemisphere of an integral part. Alternatively, the present invention may be a globe display device which has internally installed driving circuitry and wireless communication device mounted inside of the globe. The display device is capable of communicating with any Smartphone with an APP for operation, or a separate control device.

Abstract: The present invention provides a projection display system having a three-dimensional convex display surface, such as a spherical or hemispherical display surface, in which the condenser lens before the optical modulating device may have a reduced focal distance for focusing the light more tightly on the optical modulating device, so as to illuminate only the center portion of the optical modulating device. Alternatively, the projection display system may have a square light pipe or any shaped light pipe in the optics in order concentrate the light to illuminate only a center portion of the optical modulating device or devices. The light pipe may be at least one of a round shape, pentagonal shape, a hexagonal shape, an octagonal shape, etc.

Abstract: A display system has a display surface having a three-dimensional convex shape. A projection system projects an object field onto a continuous image field located on the interior of the display surface the display surface is extensive in its coverage, for example subtending an angle of at least 240 degrees to provide greater hemispherical coverage.
