Electro-optical display without reflection
First Claim
1. In an electro-optical display on an instrument panel of an automotive vehicle, said display including a liquid crystal layer and a polarization filter, said display for displaying characters and symbols in said liquid crystal layer the improvement whereina depth of installation of said device on said instrument panel is commensurate with the distance between said filter and said layer;
- andmeans for swingably mounting said display on said instrument panel are provided so that a central plane through the characters and symbols of the liquid crystal layer is selectively arrangeable in positions other than 90 degrees relative to a direction in which the observer sitting normally in the vehicle views the liquid crystal display and the configuration of the characters and symbols appearing in the liquid crystal layer is a projection of characters and symbols which is perceivable by the observer from a plane vertical to said direction of view of the observer to said plane of the liquid crystal layer.

Abstract
An electro-optical display for displaying characters and symbols on a display surface facing the viewer on the instrument panel of an automotive vehicle without specular reflection, particularly a liquid-crystal display therefor. The display surface is swingably arranged in a position other than 90 degrees relative to the direction in which the observer views the display surface and the characters and symbols are represented in such distorted manner on the display surface that they can be perceived without distortion from the direction of view of the observer.

10. In an electro-optical display for displaying characters and symbols in a liquid crystal layer of the display on an instrument panel of an automotive vehicle, the improvement wherein
the layer of said display is curved and is variably arrangeable in a position other than 90 degrees relative to a direction in which an observer sitting normally in the vehicle views the liquid crystal display; -
said display comprising said liquid crystal layer and a polarization filter curved as said to maintain a spacing between said layer and said filter; and
whereinthe characters and symbols appearing in the liquid crystal layer are a projection of characters and symbols which are perceivable by the observer from a plane vertical to said direction of view of the observer to said plane of the liquid crystal layer; and
whereina depth of installation of said device on said instrument panel is commensurate with the distance between said filter and said liquid crystal layer.

11. A dereflected electro-optical display for representing characters and symbols on a display surface thereof facing a viewer on an instrument panel of a motor vehicle having windows and defining a longitudinal axis, wherein
said display surface is arranged in a position wherein a central perpendicular to the display surface is downwardly inclined at an angle relatively to the longitudinal axis of the vehicle, and light arriving from the windows and reflected at the display surface is reflected into a region which is situated below viewing direction of the viewer viewing the display, and means for pivotally coupling said display to said instrument panel are provided so that said angle is selectively variable.
