En plus de v\u00e9rifier les param\u00e8tres des produits, ainsi que les certifications d'usine et les certifications de normes produit, comment pouvons-nous \u00e9valuer la qualit\u00e9 du produit en l'observant ?<br \/>\nNous pourrions v\u00e9rifier la qualit\u00e9 du panneau LCD en examinant certains d\u00e9tails, notamment l'apparence, le contraste, la luminosit\u00e9, la couleur d'affichage, le temps de r\u00e9ponse du signal, l'angle de vision, la fr\u00e9quence de rafra\u00eechissement de l'\u00e9cran, etc.<\/p>\n<p style=\"text-align: justify\">1 : Tout d'abord, lorsque nous obtenons un panneau d'affichage TFT, la m\u00e9thode la plus simple et la plus intuitive consiste \u00e0 v\u00e9rifier la qualit\u00e9 en observant l'apparence. Un produit de qualit\u00e9 excellente pr\u00e9sente \u00e9galement une tr\u00e8s bonne apparence. L'\u00e9cran ne comporte pas de rayures, le mat\u00e9riau du cadre ext\u00e9rieur est lisse et brillant, la couleur d'apparence est uniforme, la soudure du FPC est solide et il n'y a pas d'irr\u00e9gularit\u00e9 au niveau des points de soudure du FPC. Ces soudures de FPC sont toutes r\u00e9alis\u00e9es sur machine, et il n'y a g\u00e9n\u00e9ralement pas de probl\u00e8me. Mais nous v\u00e9rifions le m\u00e9canisme de contr\u00f4le de l'usine. Les ouvriers doivent \u00eatre minutieux lors de l'inspection des produits et du tri des produits d\u00e9fectueux ; un bon fabricant d'\u00e9crans LCD ne laissera pas les produits d\u00e9fectueux parvenir aux clients. La probabilit\u00e9 d'une telle situation est tr\u00e8s faible.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter wp-image-7573\" src=\"https:\/\/rjoytek.com\/wp-content\/uploads\/2022\/11\/quality-of-lcd-panel-1024x658.jpg\" alt=\"\" width=\"500\" height=\"322\" srcset=\"https:\/\/rjoytek.com\/wp-content\/uploads\/2022\/11\/quality-of-lcd-panel-1024x658.jpg 1024w, https:\/\/rjoytek.com\/wp-content\/uploads\/2022\/11\/quality-of-lcd-panel-1000x643.jpg 1000w, https:\/\/rjoytek.com\/wp-content\/uploads\/2022\/11\/quality-of-lcd-panel-300x193.jpg 300w, https:\/\/rjoytek.com\/wp-content\/uploads\/2022\/11\/quality-of-lcd-panel-600x386.jpg 600w, https:\/\/rjoytek.com\/wp-content\/uploads\/2022\/11\/quality-of-lcd-panel.jpg 1143w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify\">2 : Contraste, nous pouvons observer le contraste de l'\u00e9cran <a href=\"https:\/\/rjoytek.com\/what-causes-lcd-panel-failure\/\"  data-wpil-monitor-id=\"44\">l'\u00e9cran LCD<\/a> via une vid\u00e9o. Lors du test du produit, des images de couleurs RVB sont g\u00e9n\u00e9ralement fournies pour v\u00e9rification. Nous devons v\u00e9rifier la puret\u00e9 des couleurs rouge, verte et bleue, bien s\u00fbr, pour une personne ordinaire, cela n'est pas facile. Un bon produit offre une excellente performance de couleur et un bon contraste.<\/p>\n<p style=\"text-align: justify\">Nous devons \u00e9galement v\u00e9rifier si l'\u00e9cran LCD pr\u00e9sente des points blancs ou noirs \u00e0 l'aide d'images blanches et noires. Ces points de couleur impure sont soumis \u00e0 des normes de contr\u00f4le sp\u00e9cifiques. S'il y a trop de points blancs ou noirs sur l'\u00e9cran, vous devriez alors consid\u00e9rer que le panneau d'\u00e9cran LCD que vous avez obtenu pr\u00e9sente des probl\u00e8mes de qualit\u00e9. Plus le panneau d'\u00e9cran LCD est de qualit\u00e9, moins il y a d'anomalies de points noirs ou blancs, vous devez donc examiner attentivement votre panneau LCD TFT.

Vous pouvez ouvrir une vid\u00e9o de votre choix et l'observer sous diff\u00e9rents angles. Si la sp\u00e9cification indique qu'il s'agit d'un \u00e9cran IPS, alors l'angle sous lequel l'image reste claire est relativement large. Si vous constatez qu'elle est floue lorsque vous regardez de c\u00f4t\u00e9, votre \u00e9cran n'est peut-\u00eatre pas un IPS strict. L'\u00e9cran avec angle de vision ; que ce soit en inversion gauche-droite ou verticale, il doit \u00eatre centr\u00e9 sur l'axe parall\u00e8le de l'\u00e9cran LCD, en se d\u00e9pla\u00e7ant de haut en bas, de gauche \u00e0 droite. Si vous pouvez voir clairement une image similaire \u00e0 la plage d'angle indiqu\u00e9e dans la sp\u00e9cification, alors votre \u00e9cran LCD est de bonne qualit\u00e9.<\/p>\n<p style=\"text-align: justify\">4 : Temps de r\u00e9ponse du signal<br \/>\nLe temps de r\u00e9ponse du signal fait r\u00e9f\u00e9rence \u00e0 la rapidit\u00e9 avec laquelle le LCD r\u00e9agit \u00e0 un signal d'entr\u00e9e, g\u00e9n\u00e9ralement exprim\u00e9 en millisecondes (ms). Lors des tests, vous devez porter une attention particuli\u00e8re \u00e0 la vitesse de changement d'image et au temps de r\u00e9ponse de l'\u00e9cran. Si le temps de r\u00e9ponse d\u00e9passe 40 ms, il y aura un d\u00e9calage de l'image en mouvement, ce qui provoquera une r\u00e9manence ou des tra\u00een\u00e9es sur l'\u00e9cran. Bien s\u00fbr, \u00e0 moins que l'image ne se d\u00e9place tr\u00e8s lentement, vous ne le remarquerez peut-\u00eatre pas facilement.<\/p>\n<p style=\"text-align: justify\">Ce qui pr\u00e9c\u00e8de sont toutes des m\u00e9thodes permettant de v\u00e9rifier simplement la qualit\u00e9 du panneau d'affichage LCD.
