Manufacturing methods of flexible substrates and flexible panels by screen printing machines

A manufacturing method of flexible substrates via a screen printing machine, the screen printing machine comprising a stencil having at least one opening, a back-ink blade above the stencil, a scraper, and adhesive material, a bottom side of the stencil being configured with a substrate arranged, the manufacturing method comprising:

• moving the back-ink blade and the scraper along a first direction, the scraper being arranged above the back-ink blade, and the back-ink blade being configured to coat the adhesive material on the opening;
• moving the back-ink blade and the scraper along a second direction opposite to the first direction, the scraper being lowered down to a position below the back-ink blade, the scraper printing the adhesive material from the opening to the substrate so as to form a flexible substrate thin-film corresponding to the opening area on the substrate;
• and
• applying a baking process on the flexible substrate thin-film to obtain a cured flexible substrate, wherein a temperature of the baking process is in a range from 350 to 500 Celsius degrees, a time period of the backing process is in a range from 2 to 4 hours, and a thickness of the flexible substrate is in a range from 20 to 400 micrometers.
