Abstract :
Avionic cockpit display applications require AMLCD´s having extended and specific viewing angle characteristics. A typical cone is +/-60 degrees horizontal, and 0 to +30 degrees vertical. We used a Berreman 4×4 matrix based model to identify the necessary birefringent film values to optimize the display. The key parameter in the model was maximizing the region where the contrast ratio is greater than 50:1, without distorting the color gamut. We will show how well our current production units match our modeling results
