Abstract

Una estructura de posicionamiento de una placa de guía de luz, un módulo de luz de fondo, y un dispositivo de pantalla, la cual comprende: una pluralidad de miembros de posicionamiento (20) que se disponen entre una primera cara de una placa de guía de luz (3) y una placa posterior (1), en donde la primera cara está adyacente a una cara de incidencia de la luz de la placa de guía de luz (3), y la reflectividad de la superficie de los miembros de posicionamiento (20) más cercanos a la cara de incidencia de la luz es menor que la reflectividad de la superficie de los miembros de posicionamiento (20) más alejados de la cara de incidencia de la luz.
