Abstract
Having a microlens array on one side of the lightguide plate is now widespread in cell phone backlight systems. This paper describes a new design for the cell phone lightguide plate, which uses microlens array structure on one side and a progressive V-cut freeform surface on the other side. The illumination distribution of the lightguide becomes more reasonable. The results of the simulation show that the illumination of the lightguide plate is double that of a plate with only a microlens array in one side. If this lightguide is adopted, a layer of 3M brightness enhancement film can be reduced.
