A touch screen, also known as a touch panel, refers to a touchable screen that is usually covered with a pressure plate on a semi reflective LCD skin. It is highly sensitive to pressure, and when an object is pressed on it, a current signal is generated to determine the position of the pressure source, which can be dynamically tracked.
The use of touch screens is very extensive, from common PDAs, ATMs, smartphones, to industrial touch computers, and so on.
ELAPLUS Touch Screen Fit Solution
Optical bonding technology is used to bond a protective transparent overlay screen to the underlying LCD panel. Using this fitting method can usually eliminate the air gap between the two layers and greatly improve the visibility of the screen.
| ● Excellent realistic effects ◇ Fast and accurate touch response time ◇ Can achieve a larger display size than other packaging methods ◇ Organic silicon adhesive can maintain transparency for a long time ◇ Generating high contrast displays with less device power at lower operating temperatures | ● Enhance display images ◇ Higher resolution and clearer display ◇ Low surface and ambient light reflection ◇ Broader perspective ◇ Reduce eye fatigue caused by reflexes ◇ Stability/low modulus helps to avoid the Mura effect |
| ● Improve user experience/sensory experience ◇ Prevent condensation and atomization in humid environments ◇ In harsh environments, resistant to scratches and dirt ◇ Eliminate the impact of CTE differences between different materials ◇ Support multi touch display screen interaction ◇ Anti-vibration and anti-vibration sealing ◇ More flexible and lightweight manufacturing display screens | ● Potential applications ◇ Higher brightness lighting environment ◇ Automotive, consumer, and industrial electronics ◇ Large advertising screen or educational black and white board ◇ Direct display technology ◇ Optical packaging and other functional applications ◇ Structural display screen and touch sensor components |
BEGEL thermal-curing gel
The display screen and touch screen are mainly fully bonded with optical adhesive, which is a silicone gel elastomer with colorless transparency, high light transmittance, and small curing shrinkage.
BEGEL8506A/B organic silicon liquid optical adhesive can be used with BESIL9096 sealant as a cofferdam.
