LIQUID CRYSTAL DISPLAY APPARATUS AND LIGHT EMITTING ASSEMBLY WITH LIGHT TRANSMISSION CONTROL ELEMENTS FOR ILLUMINATING SAME
摘要
A liquid crystal display apparatus (500) including a liquid crystal display (LCD) panel (502), a light emitting assembly (501) arranged to illuminate the LCD panel, and a light conditioning element (510) between the light emitting assembly and the LCD panel. The light emitting assembly includes a planar optical conductor (158) characterized by a length and a width. The optical conductor has a light input surface (225), light transmission control elements (151) and well defined light extracting optical elements (157) configured to redirect light received at the light input surface out from the optical conductor. The light transmission control elements divide the optical conductor into independently operable light emitting regions (152). An LED light source (156) is optically coupled to each of the light emitting regions adjacent the light input surface of the optical conductor. Each LED light source is small relative to the length and width of the optical conductor.
