Advantages of optical bonding:

The strength of VacuBond^_® dry optical bonding becomes evident when bonding electronic paper, which, in contrast to a TFT displays, has no mechanically stable structure, and no bezel. The high-tech silicone OPTαGEL^® securely connects the e-paper with a protective glass, or foils to a unit. The smooth surface of the e-paper is susceptible to scattered light and reflections, which is further exacerbated by the air gap between the e-paper, and a tape-bonded protective glass. The OPTαGEL^®fills this air gap, reduces reflections, prevents the ingress of moisture, and dirt, thus ensuring a high-contrast display of the e-paper contents. In addition to protective glass, Apollo displays also bonds foils that evenly distribute the light of the front lighting. Not only is our OPTαGEL^® long lasting, but e-paper bonding process is reversible, too.

As a medium-sized company, we specialize in order quantities of approx. 25,000 pieces / year, but also  co-operate with OEMs:

•  We install a complete bonding system on site (identical to ours)
•  We supply the latest machine control
•  We train the partners in constructing the production tools
•  We train the production team on the basis of current bonding

Advantages of optical bonding:

• Improved readability without increased power consumption:
  By eliminating the air gaps between the TFT display and the cover glass/touch, the light refraction is reduced and the contrast increased significantly
• No condensation or fogging:
  Optical bonding avoids the air gap between the panes of glass – moisture cannot penetrate
• No contamination:
  Optical bonding avoids the air gap between the panes of glass – dust and dirt cannot penetrate
• The danger of splintering glass is considerably reduced by the full-surface fixing / bonding with the high-adhesive Opto-Gel
• High Vibration and shock resistance:
  Optical bonding increases the strength and resiliance of the TFT Display; the high tech optoGel counteracts vibration resonances and dissipates shock energy to the sides 
  • The shock resistance was proven by drop-ball tests. The video shows drop ball tests with a smart phone: The first one with an Opto-gel protective film, the second one without protective film.
• Improved heat dissipation (up to factor 8):
  By eliminating the isolating air gap between the panes of glass, heat can dissipate through the front glass.
• Certifications:
  Together with our customers a wide variety of certifications in agricultural machinery, automation, automotive, avionics, MIL, ourdoor and railway were carried out successfully.
