Claim Text:
1. A computer-implemented method for generating a spatial arrangement of a plurality of elements of a discrete pattern for use in a display device, the plurality of elements being arranged in a spatially discrete manner, the method being executable by a processor device of a computer system, the method comprising: determining, by said processor device, for each of said elements, a density in an initial position given to the element from a density distribution of the elements in a region where said elements are arranged in said discrete pattern and placing, for each of said elements, a figure and a movement range of said figure, said figure having a size corresponding to said density and representing a region where said element repels other elements; solving, by said processor device, an optimization problem so as to minimize an objective function for imposing a penalty on each of a collision between said figures and a protrusion of said figure from said movement range using a position of each of said figures as a decision variable and computing an optimal solution of the position of each of the said figures; and outputting, by said processor device, the optimal solutions of the positions of said figures as said spatial arrangement of the elements to a display device, wherein each of said elements is a dot, said discrete pattern is a dot pattern including the plurality of dots being two-dimensionally discrete, each of said figures is a circle, and a radius r where r wherein said display device includes a backlight unit having a light guide plate that generates a luminance distribution for said display responsive to a scatter pattern, said output solution including position coordinate data representing positional coordinates of each dot in said discrete dot pattern applied to generate the scatter pattern in the light guide plate to reduce a luminance non-uniformity for said display.
