Milestrong's STJ Series transparent LED film display allows for two methods of installation: back side pasting and front side pasting. Steps to be followed in order to ensure seamless and safe installation are highlighted below.

Back Side Pasting
1. Preparation for Installation: Apply a good bond in the STJ LED film display on the front side of the glass using a rubber roller without water.
2. Peel the Back Side Protective Film Off: The protective film at the back of the LED film display should be peeled off.
3. Position Correctly and Fix: Place the film correctly and attach it to the surface of the glass using the rubber roller.
4. Air Bubbles: Check for air bubbles and remove them to get a smooth application.
5. Glass Glue Cleaning: Cleaning of excess glass glue from the connection plate before installing the power box.
6. Curing Time: Time taken between pasting the film and applying glass glue to sitting 24 hours without doing anything else to it, with the installation of the power box.
7. Installing Power Box: If the power box is on top, fix it with glass glue. Ensure the glass glue is scraped flat and an extra amount is cleaned off the board for firm attachment.

Front Side Pasting
1. Preparation: Before installation, prepare all the tools. Fill a spray bottle with water and a few drops of soap, then clean the glass thoroughly.
2. Peel and Spray: Peel off the front protective film and spray water evenly onto the adhesive surface of the film and the glass.
3. Dry key areas: Wipe off excess water from the connecting board and the area to be pasted by the board.
4. Positioning: Secure, in a desired position, the film, and spray water evenly on the back side.
5. Water Removal: Scrape off excessive water in the connection parts between the board and the film, then scrape the whole surface of the film. Apply firm and rapid pressure in scraping.
6. Final Check: When the water has already been removed completely, check for the installation to be perfect or with bubbles or some remaining water.
7. Cleaning of Glass Glue: Clean extra glass glue on a connection plate before mounting a power box.
8. Setting Time: Take 24 hours as the setting time for the film and glass glue before fixing the power box.
9. Installation of Power Box: Install the power box with glass glue; scrape it flat to ensure the uniformity of the glue. Scrape off the extra glue to avoid falling off.
10. Peeling off Final Protective Film: Peel off the protective film from the back side after installation at the corner to ensure the translucency of the product.

These will serve the purpose of establishing transparent LED display Milestrong STJ Series in a professional manner that is durable. Good preparation will lead to an appropriate display and long life.
