What is ‘Direct Optical Bonding’?

Direct Optical Bonding is a proprietary manufacturing process adopted by Sharp Visual Solutions for their latest BIG PAD SC5 interactive displays[i].  Unlike conventional LCD display construction and assembly processes, the LCD panel is bonded directly to the protective glass touch layer with a transparent gel-like adhesive. This ensures zero air gap between the different transparent layers of the touch display and achieves the closest possible visual proximity of the glass touchscreen surface to the displayed on-screen content.  The result is minimised parallax differential, reduced internal reflection and reduced refraction of light to deliver an extremely precise touch experience along with the best contrast and visual performance available for an interactive LFD.

[1] Models featuring Direct Optical Bonding are the PN-80SC5 80 inch and PN-70SC5 70 inch with PN-60SC5 60 inch launching at a later date.

 


 

 

 

 

 

 

What is ‘Parallax Differential’ and why is it important?

Interactive touchscreen LFDs have become a standard tool for teachers in education and for collaboration in modern meeting and operations rooms. Accuracy, speed and responsiveness in these situations is crucial for efficient working and enjoyable use of the display. All too often the experience with some earlier generation touchscreen LFDs was that physical location of the pen or finger on the sensor glass was shown on the LCD display some distance from the intended location. This ‘parallax differential’ resulted in confusion, inaccuracy, lost time and a poor user experience. Direct optical bonding eliminates all these drawbacks, with pinpoint touch accuracy and a more natural user experience.
