Abstract: A method to generate random and density controllable dot patterns on an optical device includes steps of dividing a 2D domain into multiple cell units; determining dot density in each cell; creating at random initial location of dots in each cell; solving the force operation cut radius of the dot; setting up a residual force; solving the force control parameter in the cell; performing the force operation for the cell; making the dots in the cell to achieve balanced positions after repeated operation; completing the generation of a dot pattern within a 2D domain; and transferring the dot pattern to the optical device by a transfer printing equipment.

Abstract: A light guide plate having micro-reflectors is to increase luminance of the light guide plate by changing light route. The light guide plate includes an incidence plane, an illuminating plane, and a bottom. Each of the micro-reflectors is disposed at the bottom and intersected with the light guide plate in a direction heading for a recess provided at the bottom of the light guide plate, and comprises a light reflection plane located between the incidence plane and the illuminating plane to define an angle ?. The light reflection plane is an arc quadrilateral or a sector when observed from top of the illuminating plane. The arc quadrilateral has two concentric arc sides parallel with each other.

Abstract: A light guide plate having micro-reflectors is applied to a back light module of a liquid crystal display. A light source is disposed on one side of the light guide plate. Each of the micro-reflectors is shaped like a pyramid protruding from the bottom of the light guide plate and comprises a transparent plane and two reflection planes. The transparent plane is disposed at right angle to the bottom of the light guide plate, facing and comparatively nearer to the light source. Both the reflection planes are inclined to the bottom of the light guide plate, facing the illuminating surface of the light guide plate and comparatively farther from the light source to reflect rays of light upward to increase luminance of the light guide plate, and thereby changing arrangement of the micro-reflectors to improve consistent luminance of the light guide plate.
