Abstract

Visible-light Excited Phosphor Sheet (VEPS) system applies blue LED chips to excite the extrinsic flat YAG-phosphor layer to perform uniform and flat lighting, that can further reduce the backlight thickness but to complicate the lightemitting mechanism. In this paper, the optical properties of VEPS system were discussed. Besides, a theoretical model was developed to optimize the geometrical structure of VEPS system. Consequently, the optimized result was demonstrated on the small-sized VEPS module.
