摘要:本发明公开了一种曲面光栅及曲面显示装置,包括:多个光栅周期,各光栅周期均包括位于中间的开口区和位于两侧的遮光区;位于曲面光栅中心线两侧且与中心线之间距离相等的光栅周期的宽度相等;光栅周期的宽度随着光栅周期与中心线之间距离的增大而等间距减小,光栅周期的开口区的宽度随着光栅周期与中心线之间距离的增大而等间距减小。将曲面光栅设置成光栅周期宽度和开口区宽度随其与中心线之间的距离增大而等间距减小,从而可使各像素单元在透过对应的光栅周期开口区的边缘时,菱形观看区域在垂直与曲面光栅方向上的顶点向两侧延伸,由此使观看者在该方向上具有更广的观看空间。

Abstract: The invention discloses a curved surface grating and a curved surface display unit, which comprises multiple grating periods, each grating period comprises opening area in the middle and shading area in the both sides; The width of the grating cycle which is on the both sides of the center line of the surface grating and equal to the distance to the center line is equal; the width of the grating period decreases in equal interval with the increasing distance between the grating period and the center line, the opening area width decreases in equal interval with the increasing distance between the grating period and the center line. The width of the grating and the width of the opening area are increased in equal interval with the decreasing distance to the center line, So that each pixel unit penetrates the edge of the corresponding grating period opening area, the rhombic viewing area extends to both sides on vertex in the direction of the vertical to curved grating, thus, the viewer has a wider viewing space in that direction.
