Abstract
An autostereoscopic display apparatus and a method for reducing crosstalk are disclosed. The apparatus includes an array of display pixels arranged in rows and columns, and an array of elongated optical elements extending parallel to one another and overlying the display pixels. For any given pixel, an optimized display value is determined according to a compensation equation based on the pixel's original value, a corresponding pixel value for the other viewpoint, and adjustable coefficients.

An autostereoscopic display apparatus, comprising:
- an array of display pixels arranged in rows and columns;
- and
- an array of elongated optical elements extending parallel to one another and overlying the display pixels, wherein for any given pixel, an optimized display value (final_c) is determined based on the following equations:
- whenc<c_inv,final_c=c+=(c−c_inv)×cp;
- whenc>c_inv,final_c=c+(c−c_inv)×cn,
- wherein c is an original display value of the given pixel, c_inv is a display value of a corresponding pixel for the other viewpoint, cp is a coefficient greater than 0, and cn is another coefficient greater than 0, wherein the coefficients cp and cn are adjustable to compensate color values.
A method for reducing crosstalk in an autostereoscopic display apparatus comprising an array of display pixels and an array of elongated optical elements, the method comprising:
- for each given pixel, determining an optimized display value (final_c) according to the following equations:
- whenc<c_inv,final_c=c+(c−c_inv)×cp;whenc>c_inv,final_c=c+(c−c_inv)×cn,
- wherein c is the original display value of the given pixel, c_inv is the display value of a corresponding pixel for the other viewpoint, cp and en are coefficients greater than 0, and the coefficients cp and cn are adjustable to compensate color values.
