Claim:
A parallax barrier 3D image display method, applied to reduce transverse ghost images, comprising: providing a screen of a flat panel display formed of red green, blue (R, G, B) sub-pixel units, wherein a single sub-pixel unit is formed of a color filter and a black matrix, a horizontal width of the single sub-pixel unit is P, a horizontal width of the color filter is C, and a horizontal width of the black matrix is 2b, P=C+2b, and a multi-view 3D image is displayed on the screen of the flat panel display in unit of sub-pixels; and providing a vertical strip parallax barrier formed of vertical strip light-transmissive elements and vertical strip shielding elements arranged alternately, wherein a horizontal width of a single vertical strip light-transmissive element is B′ t , and a horizontal width of a single vertical strip shielding element is B′ t ; the vertical strip parallax barrier is installed in the front of the screen of the flat panel display at an installation distance L B , and completely separates a view image of the multi-view 3D image at multiple best viewing points on an optimum viewing distance Z 0 ; wherein a design value of the horizontal width B′ t of the light-transmissive element is calculated through the following formula: B t ′ = n ⁡ ( 1 - C P ) ⁢ B 0 , a design value of the horizontal width B′ t of the shielding element is calculated through the following formula: B t ′ _ = [ N - n ⁡ ( 1 - C P ) ] ⁢ B 0 , n is an opening enlarging factor and is a positive real number satisfying 1≦n≦C/2b and n ≤ C 2 ⁢ b - P b ⁢ Δ ⁢ ⁢ L E L V , where ΔL E is a distribution deviation of eye interval, N is a total view number and is a positive integer satisfying N>2; B 0 is calculated through the following formula: B 0 = L V P + L V ⁢ P , L v is a distance between the best viewing points.
