摘要: A backlight assembly (100) for providing bright and uniform light beams to illuminate an LCD panel includes a source (120), reflector (130), diffusion sheet (150). The is positioned between the sheet, has at least one diffraction grating (151) formed on surface thereof facing source. simple configuration panel. Furthermore, made of transparent piezoelectric material. When electric field applied by controlling circuit, induced deform. Thus distribution intensity can be modulated according need.
