Abstract
(EN)
A liquid crystal display, comprising a backlight module (10), a liquid crystal display panel (30), and a dynamic backlight light-shielding plate (20) located between the backlight module (10) and the liquid crystal display panel (30), wherein the dynamic backlight light-shielding plate (20) includes a reflective electroluminescent material. The liquid crystal display has the beneficial effects of the dynamic backlight light-shielding plate (20) including a reflective electroluminescent material being arranged between the liquid crystal display panel (30) and the backlight module (10), that is, further improving the dynamic contrast ratio, and further improving the utilization rate of a light source of the backlight module (10).

L'invention concerne un affichage à cristaux liquides, comprenant un module de rétroéclairage (10), un écran d'affichage à cristaux liquides (30), et une plaque de protection contre la lumière de rétroéclairage dynamique (20) situé entre le module de rétroéclairage (10) et l'écran d'affichage à cristaux liquides (30), la plaque de protection contre la lumière de rétroéclairage dynamique (20) comprenant un matériau électroluminescent réfléchissant. L'affichage à cristaux liquides a les effets bénéfiques de la plaque de protection contre la lumière de rétroéclairage dynamique (20) comprenant un matériau électroluminescent réfléchissant disposé entre l'écran d'affichage à cristaux liquides (30) et le module de rétroéclairage (10), c'est-à-dire améliorant davantage le rapport de contraste dynamique, et améliorant en outre le taux d'utilisation d'une source de lumière du module de rétroéclairage (10).
