Abstract

The random dot pattern generation by the use of molecular dynamics (MD) is proposed to the light guide design used for the backlight. Several numerical techniques are developed to provide the great advantage for the combination the subsequent optical optimization for the dot density adjustment satisfy the uniformity requirement demanded by the LCD display. The cell divisions technique is proposed, which allows the dot density adjustment within each cells dividing from the light guide. In addition, the technique is developed to account for different cells to localize the repulsive force acting within the cell to achieve high dot density gradient in the dot distribution. Moreover, the average force control technique is developed to handle the uniformity of dot distribution across the cell boundary. Finally, several illustrations are included to show the validity the robustness of the proposed MD dot generation algorithm.
