Avec l'\u00e9volution rapide de la soci\u00e9t\u00e9, diverses industries pr\u00e9conisent la production de produits respectueux de l'environnement, et l'industrie des LED ne fait pas exception \u00e0 la r\u00e8gle. Les \u00e9crans transparents \u00e0 LED ont \u00e9t\u00e9 largement utilis\u00e9s dans diff\u00e9rents coins de la ville et sont devenus un symbole unique pour am\u00e9liorer l'image de la ville et embellir son apparence. L'industrie des LED doit \u00e9voluer avec son temps, r\u00e9pondre \u00e0 l'appel national et promouvoir des produits \u00e9conomes en \u00e9nergie et respectueux de l'environnement. Il est bien connu que les \u00e9crans d'affichage \u00e0 LED peuvent ne pas atteindre une efficacit\u00e9 \u00e9nerg\u00e9tique id\u00e9ale en raison de leur forte luminosit\u00e9, mais cela ne signifie pas qu'ils doivent \u00eatre des produits \u00e0 forte consommation d'\u00e9nergie. Alors, comment les \u00e9crans transparents \u00e0 LED peuvent-ils \u00eatre plus efficaces sur le plan \u00e9nerg\u00e9tique ?<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Choisir des mat\u00e9riaux respectueux de l'environnement <\/strong>
Le choix d'un \u00e9cran d'affichage LED fabriqu\u00e9 \u00e0 partir de mat\u00e9riaux respectueux de l'environnement, trait\u00e9s par des techniques sp\u00e9ciales, \u00e9limine le besoin de colle et conf\u00e8re \u00e0 l'\u00e9cran des propri\u00e9t\u00e9s d'\u00e9tanch\u00e9it\u00e9, de r\u00e9sistance \u00e0 la poussi\u00e8re et aux UV. Par rapport aux produits fabriqu\u00e9s selon des proc\u00e9d\u00e9s conventionnels, cette approche consomme moins de mat\u00e9riaux, ce qui la rend plus respectueuse de l'environnement.<\/p>\n\n\n\n

Technologie de r\u00e9duction du bruit \u00e0 courant constant <\/strong>
La puce de pilotage de l'affichage LED adopte un syst\u00e8me de puce d\u00e9di\u00e9 \u00e0 l'affichage LED avanc\u00e9 au niveau international, qui est \u00e0 la pointe de l'industrie dans le domaine des affichages LED en couleur. En combinant les caract\u00e9ristiques de la puce, une technologie de r\u00e9duction du bruit \u00e0 courant constant a \u00e9t\u00e9 mise au point pour r\u00e9duire au minimum l'impact de l'alimentation \u00e9lectrique et d'autres sources de bruit sur les \u00e9crans \u00e9lectroniques \u00e0 DEL. Certains circuits d'attaque peuvent \u00e9galement \u00e9conomiser de l'\u00e9nergie en r\u00e9duisant la tension d'origine de 5V \u00e0 4,2V, ce qui permet d'obtenir une fonctionnalit\u00e9 d'\u00e9conomie d'\u00e9nergie.<\/p>\n\n\n\n

Utilisation d'un syst\u00e8me de r\u00e9glage automatique de la luminosit\u00e9 <\/strong>
En fonction du jour et de la nuit, des lieux et des p\u00e9riodes, de l\u00e9g\u00e8res variations de la luminosit\u00e9 de l'\u00e9cran d'affichage peuvent avoir un impact significatif. Si la luminosit\u00e9 de lecture de l'\u00e9cran LED est sup\u00e9rieure \u00e0 50 % de la luminosit\u00e9 ambiante, nous ressentons une g\u00eane oculaire \u00e9vidente, ce qui entra\u00eene une \u201cpollution lumineuse\".<\/p>\n\n\n\n

Technologie de correction des gris \u00e0 plusieurs niveaux<\/strong>
Les syst\u00e8mes d'affichage LED conventionnels utilisent une hi\u00e9rarchie d'affichage des couleurs de 18 bits. Dans certains niveaux de gris bas et certaines transitions de couleur, les couleurs peuvent sembler dures, ce qui entra\u00eene une g\u00eane lors de l'adaptation \u00e0 la lumi\u00e8re color\u00e9e. Le nouveau syst\u00e8me de contr\u00f4le du grand \u00e9cran LED adopte une hi\u00e9rarchie d'affichage des couleurs de 14 bits, ce qui am\u00e9liore consid\u00e9rablement la duret\u00e9 de la transition des couleurs, rend les couleurs plus douces et \u00e9vite l'inconfort d\u00fb \u00e0 la lumi\u00e8re lorsque les gens regardent l'\u00e9cran.<\/p>\n\n\n\n

Alimentation \u00e9lectrique <\/strong>
La r\u00e9alisation d'\u00e9crans LED \u00e0 faible consommation d'\u00e9nergie se concentre principalement sur l'alimentation \u00e9lectrique. L'adoption directe d'une alimentation \u00e0 commutateur \u00e0 haut rendement en demi-pont ou en pont complet sur l'\u00e9cran LED existant, combin\u00e9e \u00e0 un redressement synchrone, produit un effet d'\u00e9conomie d'\u00e9nergie significatif. Dans l'\u00e9tat de courant constant du circuit int\u00e9gr\u00e9 de commande, des efforts sont faits pour minimiser la tension d'alimentation, afin d'obtenir un meilleur effet d'\u00e9conomie d'\u00e9nergie en alimentant s\u00e9par\u00e9ment les tubes rouge, vert et bleu.<\/p>","protected":false},"excerpt":{"rendered":"
