Abstract

La presente invención describe un dispositivo de visualización de panel plano que incluye un chasis de base, un panel de visualización, una unidad de luz trasera conectada con el chasis de base para emitir luz al panel de visualización, y que incluye un substrato montado con una pluralidad de diodos emisores de luz (LEDs), cada uno generando luz y una placa de guía de luz dispuesta entre el panel de visualización y el substrato para difundir las luces generadas desde los LEDs respectivos, y un miembro de fijación formado en cualquiera del chasis de base, el substrato, y la placa de guía de luz para una conexión al chasis de base con la placa de guía de luz. El chasis de base, el substrato y la placa de guía de luz pueden ser montados convenientemente entre sí en un tiempo sin el uso de tornillos.
