Title
(EN) COLOR NEUTRAL EMISSIVE DISPLAY WITH NOTCHED REFLECTIVE POLARIZER
(FR) UNITÉ D'AFFICHAGE ÉMISSIF DE COULEUR NEUTRE À POLARISEUR RÉFLÉCHISSANT À ENCOCHES
Abstract
(EN)
A display system is disclosed and includes a display and a reflective polarizer disposed on the display. For substantially normally incident light, for a primary wavelength λb, the reflective polarizer transmits at least 60% of the incident light having a first polarization state x and reflects at least 60% of the incident light having an orthogonal second polarization state y. For each of a first wavelength λuv and a second wavelength λbg, 0 < λbuv ≤ 100 nmand 0 < λbgb ≤ 100 nm, the reflective polarizer transmits at least 40% of the incident light for each of the first and second polarization states.

Système d'affichage comprenant une unité d'affichage et un polariseur réfléchissant disposé sur l'unité d'affichage. Pour une lumière sensiblement normalement incidente, pour une longueur d'onde primaire λb, le polariseur réfléchissant réfléchit au moins 60 % de la lumière incidente ayant un premier état de polarisation x et réfléchit au moins 60 % de la lumière incidente ayant un second état de polarisation orthogonal y. Pour chacune d'une première longueur d'onde λuv et d'une seconde longueur d'onde λbg, 0 < λbuv ≤ 100 nm et 0 < λbgb ≤ 100 nm, le polariseur réfléchissant transmet au moins 40 % de la lumière incidente pour chacun des premier et second états de polarisation.
