Display system incorporating an electro-mechanical wave transducer

摘要

A display system ( 20 ) employs a light source ( 21 ), a display panel ( 31 ), and an optical filter ( 23 ). An optical path (OP) extends from the light source ( 21 ) through the optical filter ( 23 ) to the display panel ( 31 ) where light emitted from the light source ( 21 ) propagates along the optical path (OP) through the optical filter ( 23 ) to the display panel ( 31 ). The display system ( 20 ) further employs an Nth order electro-mechanical wave transducer ( 24, 40 ) to vibrate the optical filter ( 23 ) to thereby facilitate a desired illumination of the emitted light onto the display panel ( 31 ).
