Reveal #4 – Stacking Sub-Systems and Improving Visual Performance
The Pivotal Design decision to Transform a TFT Display from Ordinary to Outstanding is in the method of “Stacking” Sub-Systems. i.e.: Cover Lens, Touch Panels, TFT Glass & Backlight.
The age-old method is to Stack each sub-system with a space in between each layer. The more effective method is to use OCA (Optical Clear Adhesive).
By Stacking with spaces, light from ambient sources will bounce around in the spacing area. In turn, light from Backlights will also bounce around causing washout of display information and a loss of clarity.
OCA eliminates all spurious light bounces and thus Clarity is increased, and Elimination of Shadowing is accomplished.
