AUTO-STEREOSCOPIC DISPLAY DEVICE WITH A LENTICULAR SHEET SLANTED WITH RESPECT TO THE COLUMN OF COLOUR SUB-PIXELS

摘要

Auto-stereoscopic display device (1) comprising display pixels (5) arranged in rows and columns of different colour sub-pixels, each sub-pixel having an aspect ratio "a" being the width-to-height ratio, a lenticular sheet (9) arranged in registration with the display (1) for projecting a plurality of views towards a user in different directions, wherein said lenticular sheet (9) comprises elongated elements (11) with a long axis that is slanted (angleΘ) with respect to the general column sub-pixel direction thereby defining a slant s = tanΘand satisfying the inequalities 0.8 s≤a≤1.2 s with s < 1/3.
