Abstract

material de base refletor para uma unidade de retroiluminação, unidade de retroiluminação, e, método para produzir um material de base refletor de espuma são providos um material de base refletor, que pode eliminar confiavelmente a geração de desuniformidade de brilho, uma unidade de retroiluminação usando o material de base refletor, e um método para produção do material de base refletor. a informação de formato de superfície do material de base refletor (7) é obtida por meio de um medidor de deslocamento a laser (3). então, a informação de rebaixo e projeção obtida é transformada por fourier, e a relação entre a frequência e a intensidade é comparada com dados de referência ajustados previamente. quando a intensidade excede 0,6 em uma região de frequência em uma faixa predeterminada, é determinada que o material refletor é não aceitável, e quando não existe dado que excede 0,6 na região de determinação, é determinado que o material de base refletor é aceitável.
