High Contrast Viewing Angle Lcd Light-Switching Element
A new concept of the normally open LCD light switching element is proposed, which allows for the superior attenuation by using a single simple negative bireffingent c-plate compensation layer. The concept is based on the simultaneous use of highly angularly symmetric S LC-configuration (preferably 1...

| description | A new concept of the normally open LCD light switching element is proposed, which allows for the superior attenuation by using a single simple negative bireffingent c-plate compensation layer. The concept is based on the simultaneous use of highly angularly symmetric S LC-configuration (preferably 180° twist) and maximal use of the single (preferably ordinary ray) light propagation mode. The solution is best suitable for various light switching applications like LCD automatic protective welding light filters, as well as for multi-segment large display panels, where it provides for excellent uniformity of the light-attenuation in the "dark" state. |
