Document Type and Number:
WIPO Patent Application WO/2020/107789
Kind Code:
A1
Abstract:
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.
