Abstract

Perfeccionamientos en aparatos indicadores, con un display electroóptico pasivo de magnitudes eléctricas con superficie la indicación rectangular, y una carcasa con una parte inferior en forma de un paralelepípedo abierto por arriba, y una superficie cubierta que porta al display en una situación inclinada respecto al plano de extensión de la parte inferior en forma de paralelepípedo, en la que los dos lados longitudinalmente de la superficie de indicación del display rectangular comprenden un ángulo con el plano de extensión, caracterizados porque la superficie cubierta está formada al menos en una zona que contiene el display, por una placa que consta de un material con un índice de refracción mayor, contiene partículas fluorescentes, tiene ventanas de salida de luz asociadas al display y está azogada preferentemente en sus superficies laterales ("placa fluorescente"), porque el display se porta por una superficie parcial de la placa fluorescente paralela al plano de extensión del display, porque para las transiciones de la superficie soporte a las restantes zonas de la placa fluorescente sirve la formula **(formula)** (R= radio de curvatura exterior, de espesor de la placa fluorescente, nf=indice de refracción de la placa fluorescente y na= índice de refracción del espacio exterior), porque especialmente los contactos eléctricos del display se hallan en por lo menos uno de ambos lados estrechados de la superficie de indicación del display y pasan al interior de la carcasa por un escote de la placa fluorescente, y porque sobre el display esta puesto un marco unido con la placa fluorescente.
