A system and method for interactive management of multiple wireless devices (such as PDA's or desktop or laptop computers) making graphical or video presentations while connected wirelessly to a display device whose wireless module converts the transmitted data from the wireless devices to the required format for display.

A liquid crystal display panel includes a counter substrate having a counter electrode and a multi-layered dielectric film both formed thereon, and an array substrate formed with pixel electrodes and thin-film transistors serving as switching elements. A layer of polymer dispersed liquid crystal material containing a UV-curable resin component and a liquid crystal component is sandwiched and sealed between the counter and array substrates. A light shielding film is formed over each thin-film transistor. The multi-layered dielectric film is a laminated structure of alternating thin-films of SiO2 and HfO2. Since the multi-layered dielectric film is of a nature capable of transmitting UV-rays of light therethrough, the UV-curable resin component positioned underneath the multi-layered dielectric film can be cured during the manufacture. Also, since the multi-layered dielectric film is of a nature capable of reflecting light of a visible region, it serves as a black matrix, reflecting the visible light modulated by the display panel. Black beads are used to keep the film thickness of the liquid crystal layer at a predetermined value. Preferably, a dielectric thin-film having a relative dielectric constant smaller than that of the liquid crystal material is formed on signal lines for transmitting signals to the thin-film transistors, to thereby accomplish an electromagnetic shield. Where color filters are to be formed on the pixel electrodes, those color filters may be formed on the signal lines to accomplish the electromagnetic shield.

A projection apparatus includes an image projection unit configured to form an image and project the formed image, a screen unit configured to display the image projected from the image projection unit, and a mounting unit on which the image projection unit and the screen unit are integrally mounted. The screen unit is formed to have a curvature.

A holographic waveguide display comprises: a source of light; at least one switchable grating layer comprising a multiplicity of grating regions each switchable between a diffracting state and a non diffracting state; means for spatio-temporally modulating light from the source to provide image light comprising at least one beam deflector for scanning the light in at least one of two orthogonal directions and at least one modulator for amplitude modulating the light. A first scanned angular range of light is diffracted through a first area into a first field of view by a first set of grating regions, and through a second area into to the first field of view by a second set of grating regions. Each grating region of the first and second sets has a first grating function. The first and second areas lie within an exit pupil of the display.

A screen for imaging a group picture of view point pictures is arranged and a screen shake detecting means and a means for correcting and controlling the group picture of the view point pictures projected on a screen to a proper position are provided.

A flexible screen with a mechanism for releasably attaching the screen to a transparent door or window is disclosed. A method of use is also disclosed.
