Abstract
(DE) Die vorliegende Erfindung betrifft eine Verbundscheibe für ein Head-Up-Display, mindestens umfassend • eine erste Scheibe (1) mit einer ersten Oberfläche (I) und einer zweiten Oberfläche (II), eine zweite Scheibe (2) mit einer ersten Oberfläche (III) und einer zweiten Oberfläche (IV) und eine thermoplastische Zwischenschicht (3), welche zwischen der zweiten Oberfläche (II) der ersten Scheibe (1) und der ersten Oberfläche (III) der zweiten Scheibe (2) angeordnet ist, • einen HUD-Bereich (B), und • eine erste Beschichtung (20) zur Reflektion von P-polarisierter Strahlung und genau eine elektrisch leitfähige Schicht (21) auf Basis von Silber aufweist, wobei eine zweite Beschichtung (30) zur Reduzierung der totalen transmittierten Wärmestrahlung vorgesehen ist.
(EN) The present invention relates to a composite panel for a head-up display, at least comprising a first panel (1) having a first surface (I) and a second surface (II), a second panel (2) having a first surface (III) and a second surface (IV), and a thermoplastic intermediate layer (3), which is arranged between the second surface (II) of the first panel (1) and the first surface (III) of the second panel (2), a HUD area (B), and a first coating (20) for reflecting P-polarized radiation and exactly one electrically conductive layer (21) based on silver, wherein a second coating (30) is provided for reducing the total transmitted thermal radiation.
(FR) La présente invention concerne un panneau composite pour un affichage tête haute, comprenant au moins un premier panneau (1) ayant une première surface (I) et une seconde surface (II), un second panneau (2) ayant une première surface (III) et une seconde surface (IV), et une couche intermédiaire thermoplastique (3), qui est disposée entre la seconde surface (II) du premier panneau (1) et la première surface (III) du second panneau (2), une zone HUD (B), et un premier revêtement (20) pour réfléchir un rayonnement polarisé P et exactement une couche électriquement conductrice (21) à base d'argent, un second revêtement (30) étant prévu pour réduire le rayonnement thermique transmis total.
