Touch panel market has shown transformation with strong growth in last 2~3
years. With the growth of market and industry, competition among new and
existing companies are deepening, thereby demand for innovative technology for
differentiating is increasing noticeably. Demand of more convenient and smart
interface touch panel is increasing.
Because of the needs of consumers, accustomed to capacitive touch through
smartphone, touch panel market is beyond mobile-size and is expanding to
10-inch range of the medium-size. Based on the universality of capacitive
touch panel technology, a larger technology development to apply to 20-inch
and above has become an issue in recent years.
Because touch panel is a component that is put on top of the finished product,
it is required to have all the optical requirements, high-transmission, thin,
and lightweight, that are required in basic display. It also needs to have
basic electrical properties to perform electrical operation. In other words,
touch panel is a device required to have optical, electrical, mechanical
(durability, etc.) features, therefore, current touch panel major development
issues can be narrowed to 7 technical issues related to performance
development; enlargement, lightweight, slim, durability, high-transmission,
narrow bezel, air gap.
According to the tendency of popularization of capacitive touch, Displaybank
issued "High-Performance Touch Panel Structure Technology Related Key Patent
Analysis" report.
This report covers Korea, U.S., Japan, Europe patents that were published by
April, 2011 and out of all 2687 cases of RAW-DATA, capacitive touch panel
structure technology related key patent were extracted for in-depth analysis.
