A method of designing a concave 3D video screen surface extending generally inwardly from a front edge of the screen surface, said screen surface including an equator dividing the screen surface into a normally upper portion and a normally lower portion, said method including the steps of:
- (a) determining a maximum screen width (Xmax);
- (b) determining a maximum screen height above the equator (Zmax);
- (c) determining a rounded corner radius (rc) for the front face;
- and
- (d) calculating the location of a plurality of screen surface points by inputting Xmax, Zmax, and rc into a master equation, said master equation being operable to define the shape of the screen surface based on Xmax, Zmax, and rc.
A concave 3D self-illuminating video screen system comprising:
- a display surface having a shape at least substantially characterized by the following master equation:
- y = ( [ 1 - ( [LeftBracketingBar] x [RightBracketingBar] P a P ) ] · b P ) 1 P , wherein a = X ma x 2 if [LeftBracketingBar] z [RightBracketingBar] < ( X ma x 2 - r c ) , a = ( X ma x 2 - r c ) + r c 2 - ( [LeftBracketingBar] z [RightBracketingBar] - ( X m ax 2 - r c ) ) 2 if [LeftBracketingBar] z [RightBracketingBar] ≥ ( X m ax 2 - r c ) , b = ( 1 - z 2 Z ma x 2 ) · ( X m ax 2 ) 2 , and P = 2 - ( k · [LeftBracketingBar] z [RightBracketingBar] Z m ax ) ,

- wherein k is in a range of from 0.1 to 0.95,
- wherein said display surface extends relative to orthogonal X, Y, and Z axes,
- wherein x is the orthogonal distance from the Y-Z plane to the display surface,
- wherein y is the orthogonal distance from the X-Z plane to the display surface,
- wherein z is the orthogonal distance from the X-Y plane to the display surface, and
- wherein the actual position of each point defining the display surface varies by less than 0.1 Xmax from the calculated position of the point as defined by the master equation.
A 3D self-illuminating video screen system comprising:
- a housing;
- and
- a concave self-illuminating video screen at least partly supported by the housing,
- said concave self-illuminating video screen including a display surface having a shape at least substantially characterized by the following equation:
- y = ( [ 1 - ( [LeftBracketingBar] x [RightBracketingBar] P a P ) ] · b P ) 1 P , wherein a = X ma x 2 if [LeftBracketingBar] z [RightBracketingBar] < ( X ma x 2 - r c ) , a = ( X ma x 2 - r c ) + r c 2 - ( [LeftBracketingBar] z [RightBracketingBar] - ( X m ax 2 - r c ) ) 2 if [LeftBracketingBar] z [RightBracketingBar] ≥ ( X m ax 2 - r c ) , b = ( 1 - z 2 Z ma x 2 ) · ( X m ax 2 ) 2 , and P = 2 - ( k · [LeftBracketingBar] z [RightBracketingBar] Z m ax ) ,
- wherein Xmax is in a range of from about 12 to about 60 inches,
- wherein Zmax is in a range of from about 0.25 Xmax to about 0.45 Xmax,
- wherein rc is less than about 0.1 Xmax,
- wherein k is in a range of from about 0.25 to about 0.75,
- wherein said display surface extends relative to orthogonal X, Y, and Z axes,
