DISPLAY DEVICE AND LENTICULAR SCREEN

摘要

The invention relates to a display device (1) comprising LC panels arranged next to each other. To reduce the visibility of a seam (24) between two adjacent LC panels and to avoid grey scale inversion, collimated light is applied. A lenticular foil (9) is used to enlarge the viewing angle in the horizontal direction. If the seam (24) is only present in a vertical direction, the widest viewing angle in the vertical direction should be chosen. This choice leads to an asymmetric viewing angle in a horizontal direction. To reduce the asymmetry in the horizontal viewing angle, the lenticulars of the screen have a trapezoidal shape. The apex angle depends on the desired spread and viewing angle symmetry in the horizontal direction.
