ABSTRACT:
Stereoscopic perspectives changing with the position of the observer's eyes create a natural depth-impression. An electronically controlled adaptive monitor is disclosed that imitates this feature without any additional devices such as glasses, so that items in front and behind the screen appear in a three-dimensional manner. Alternatively, the monitor can also be used as a high-resolution two-dimensional screen. This combined performance feature is achieved at a reasonable price by mounting a grid-shield with vertical cylinder lenses in front of the monitor. At the focal point of the cylinder lenses is an electronically controlled shadow-line grid-LCD, allowing the alternating passage of right and left pictures sequentially at 100 or 120 Hz. Depending on the position of the observer, the location of the shadow-lines is changed adaptively, while the respective right- and left-eye perspectives of the 3D-picture can be calculated in real-time simultaneously. A sensor system at the rim of the screen detects the exact head- and eye-position of the observer.
