Technology trend - Direct bonding -
In The touch panel products such as smart phones and tablet, the entire surface bonding process of the cover glass and the touch panel is essential. In recent years, (referred to optical bonding and full-lamination) bonding the entire surface of display device such as a liquid crystal panel and a cover glass with touch panel, the needs has been increasing.
By performing (optical bonding) the bonding of entire surface, can be obtained effects such as "Adhesion area is increased and rigidity is improved" and "Contrast is enhanced by suppressing the reflection and refraction of light at each interface".
In improve the yield in the process of entire surface bonding (optical bonding) process, high reliability and excellent optical properties OCA (optical transparent double-sided tape) and OCR (the optically transparent UV-curable resin), parts design of considering the reproducibility of bonding and a manufacturing apparatus for realizing a high reproducibility is required.
• Visibility improvement
• AR film unnecessary
• Power consumption reduction
• Prevent foreign matter
• Strength improvement
|Adherend||Cover glass + Transparent conductive film + Liquid crystal display module|

Smartphone tablet • Windows8 PC (Ultra book • Ultra book) • Smart TV
Smartphone tablet • Windows8 PC (Ultra book ) • Smart TV is being requested optical bonding (bonding) by OCA of the LCD module and the cover glass of GFF/G1F structure for thinner and lighter improvement. Because the initial bubble is difficult to occur, laminating from the edge position under normal pressure of "Glass bending lamination system", the yield rate is higher than other methods. Therefore, with the tremendous support from our customers, has a number of achievements.
