Title:
TRANSPARENT LED DISPLAY DEVICE INTEGRATED WITH SMPS, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/210891
Kind Code:
A1
Abstract:
This method for manufacturing a transparent LED display device may comprise the steps of: forming a wiring having a metal mesh pattern in a grid pattern on a first surface of both surfaces of a transparent heat-resistant optical PET film by using a wet etching method on the transparent heat-resistant optical PET film on which a copper layer is formed; electrically connecting a wiring of a controller PCB with the wiring having the metal mesh pattern to each other by punching the transparent heat-resistant optical PET film and soldering the wiring of the controller PCB placed on a second surface of both surfaces of the transparent heat-resistant optical PET film with the wiring of the metal mesh pattern on the first surface; mounting color LEDs on the first surface of the transparent heat-resistant optical PET film; and integrally coupling SMPS to the transparent heat-resistant optical PET film.
