Use of resin over films to attach cover window to significantly reduce cost

Samsung Display is planning to apply new materials in its production of foldable OLED panels to reduce cost, TheElec has learned.

It is planning to use optically clear resin (OCR), which is a liquid, over optically clear adhesive (OCA), which is a film form, to attach the cover window on the OLED panel, sources said.

Samsung Display previously used OCA for its foldable OLED panels, which takes longer than OCR as the transparent film must be put in place.

Instead, it will now use inkjet machines to disperse the liquid OCR on the panels which reduces production downtime and is less expensive to procure.

The inkjet machines will be supplied by STI and Samsung Display has already placed the order.

STI had already supplied inkjet machines which are being used at the display panel makers plant in Cheonan in South Korea.

The latest batch of the machines will be placed in Samsung Display’s module line at its plant in Vietnam. The machines will go through a trial run first.

The machine can disperse OCR in drops and can print the pattern on the panel while avoiding cameras, speakers or holes.

The use of the liquid over OCA films will allow Samsung Display to make the panels thinner with less bezel.
