Adhesive

The adhesive used in the display portion of the display, that directly affect the display capability of the display, is request a transparent optically uniform, and the adhesive failure such as foaming or peeling does not appear, even under various use environments that no dimensional change.

Double-sided tape (for paste of periphery)

It is used when make a air gap structure between the touch panel and display.

OCA (Optical transparent double-sided sheet. For full lamination)

The adhesive tape of the substrate-less which sandwiched between light release separator and heavy release separator, there is a urethane series and acrylic series.

Thermoplastic UV curing (The optically transparent double-sided sheet.For full lamination)

• Product structure does not change with the OCA, but there is a feature that generates a liquidity by applying heat, cross-linked by UV irradiation.

• Such as a liquid crystal panel, suitable to where dislike the local stress.

OCR (UV curing resin, For full lamination)

• Which is reactive liquid resin, there is a silicon series and acrylic series.
• Compared to the acrylic series, silicon series has excellent stability and cure shrinkage is low.

Absorbency of print step

OCA (optical transparent double-sided tape) Feature

That the pressure-sensitive adhesive tape of base material-less structure sandwiched by light release separator, the heavy release separator.

Challenge point

Absorbability of the like to the printing step of the cover glass.

→
Reflowable OCA Feature

Product structure is substantially equal to the OCA.

The difference between the OCR

• To follow-up to the irregularity cause the liquidity by applying heat.
• Apply to the place where hate the local stress such as a liquid crystal panel.

OCR (UV curing resin) Feature

Is a reactive liquid resin, cured by UV irradiation.
There are silicone-based and acrylic-based.

Challenge point

Such as display unevenness due to the curing contraction and protrusion after the bonding.

→
Hybrid OCR Feature

Handling is almost the same as OCR.

The difference between the OCR

• Generate OCA characteristics by Pretty Cure.
• For bonding after the cure, cure shrinkage reduced.
