Patent ID: 8378940

Claim:
A display apparatus, comprising: a display panel having a width-fixed pixel zone, a width-variating pixel zone and a border zone arranged sequentially from its center to its edges, wherein there are a plurality of width-fixed pixels disposed in the width-fixed zone, and there are a plurality of width-variating pixel groups disposed in the width-variating pixel zone, the width-variating pixel groups having respective widths present in a first decreasing sequence {P 1 , P 2 , . . . , P N }, wherein P 0 >P 1 , P 0 representing the width of each of the width-fixed pixels; and a lens having a focus-length-variating portion and a planar portion, wherein the planar portion is aligned with the width-fixed pixel zone, and the focus-length-variating portion is disposed to correspond to the border zone and the width-variating pixel zone, the focus-length-variating portion having a plurality of microstructure groups, and respective focus lengths of the focus-length-variating portion corresponding to the width-variating pixel groups are present in a second decreasing sequence {f 1 , f 2 , . . . , f N }; wherein the number of the width-variating pixel groups and the number of the microstructure groups are the same as an integer N, and each of the width-variating pixel groups is composed of at least one width-variating pixel, and the total number of the width-variating pixels of the width-variating pixel groups is a total count M, the total count M satisfying the following relationship: M ≧( d ×tan θ)/ P 0 ; wherein M is a positive integer, d representing the distance between the display panel and the lens, θ representing a slant view angle.
