Abstract
(EN)
A positioning method and positioning device for a display module, which achieves the real-time monitoring of the alignment accuracy of a target display module (100) in the horizontal direction by means of providing a laser alignment device between the target display module (100) and supporting platforms (200, 300), and by means of whether a light source received by receivers (521, 522) in the laser alignment device is located on the same horizontal line; the application of the laser alignment device improves the alignment accuracy of the target display module (100) and increases the yield and quality of a product.
(FR)
L'invention concerne un procédé de positionnement et un dispositif de positionnement destinés à un module d'affichage, qui réalisent la surveillance en temps réel de la précision d'alignement d'un module d'affichage cible (100) dans la direction horizontale grâce à la fourniture d'un dispositif d'alignement laser entre le module d'affichage cible (100) et des plateformes de maintien (200, 300), et selon qu'une source de lumière reçue par des récepteurs (521, 522) dans le dispositif d'alignement laser est située ou non sur la même ligne horizontale ; l'application du dispositif d'alignement laser améliore la précision d'alignement du module d'affichage cible (100) et augmente le rendement et la qualité d'un produit.
