An image display device capable of being incorporated into a projector, an HMD, or the like and capable of adjusting an image formation position for each image area, a projector, and a transmission type display device into which the image display device is incorporated. In an image display device, a refractive index distribution regarding a passing area of light emitted from an optical modulation device is changed by a pixel unit of a refractive index distribution variable panel. In a projector in which the image display device is incorporated, the refractive index distribution variable panel is inserted immediately after the optical modulation device so as to make it possible to perform focusing at all areas even for a screen (surface to be irradiated) having any shape.

A virtual cabin including: a semicircular floor to ceiling screen; a plurality of audio speakers positioned on the floor and ceiling; a ceiling mounted projector; a bass sub-woofer; at least one air vent, where the at least one air vent is adapted to provides airflow through the virtual cabin; and a seating arrangement. The ceiling screen preferably covers all the peripheral views of a room. The projector provides a visual experience associated with the virtual cabin, wherein the audio speakers are strategically place surrounding a perimeter of the floor.

A display with a detachable screen according to the present application includes a servo body and a display screen, the display screen is electrically connected to the servo body via an electric wire, the display screen is detachably connected to the servo body, and the servo body drives the display screen to move between an unfolded position and a folded position, and the electric wire is detachably connected to the display screen. The display with the detachable screen according to the present application has a simple and compact structure and occupies a small volume, and the assembling and disassembling is convenient and efficient, the display screen can be separately detached from the servo body easily, thus it is convenient to independently maintain and replace the display screen without the complicated process of detaching the entire display from an interior trimming panel of a luggage rack of a passenger aircraft.
