1. Capacitive Touch Panel Towards Simplification
The projection type capacitor is the mainstream of the touch screen technology. According to the report points out,
capacitance touch panel structure will tend to be simplified in the next few years, sensing carrier will be reduced, it
will be beneficial to the development of portable mobile devices. Facilitation project design of capacitance touch is
in two ways, one issensor-on-cover or called one glass solution, and the other is the panel embedded type touch
(in/on-cell). "
Panel embedded type touch mainly completed in the process of the panel factory integrated panel, and glass
solution depends on touch manufacturers and surface glass manufacturer cooperation or integration. Now Apple
products still use a piece of glass sensing carrier, the carrier two sides each have ITO transparent line, as for other
brand is mostly the same carrier in single coated with or two layers of ITO. For the surface glass integration touch,
this kind of single ITO line approach is a must, because the surface glass integration touch on one side is as the
touch of users.
Because of the touch screen capacitance projected annual growth rate is more than 100%, and the surface glass
also became one of the most important components of touch screen. Whether the glass surface integration or panel
embedded type touch, from beautiful and protect point of view, the glass surface for the projection of the touch
screen type capacitor is a must. According to the technical requirement and specification, the surface glass belongs
to the labor-intensive industries, yield is about 70%. The improvement of the process to make the yield up will be a
problem the industry needs to consider. In view of technology and supply chain characteristics, current touch
module factory and surface processing glass established the close cooperation, and some touch module factories
have even started to build their own factory surface of the glass production.
Price analysis by area and size
The whole touch industry remains in a change development period, and also each region and characteristics of the
development situation is not the same. Although touch sensor manufacturing and laminated process most is
automatic, but human remains very important, especially in the testing phase. Because Japan human cost is high,
supply chain also is very complicated. Mainland Chinese suppliers can provide the lowest price mobile phone
touch sensor. Taiwan manufacturer can provide touch sensors used in tablet computer with a lower price, this is
because Taiwan in the supply chain dominant more in the big generation (above G4.5) process of yellow touch
sensors.
At present the most popular mobile computer size is about 9.7 and 10.1 inch, and the average selling price of each
inch is about $1 to $1.5. DisplaySearch estimated touch sensor average price will fall gradually. But it also
depends on the shipments and demand, such as the average price of the popular notebook computer size (> 11.6)
touch sensor is still high.
The curve glass surface is a new direction of the design
As many Smartphone with touch function are very similar, so mobile phone brand manufacturers try to use the
curve glass surface to make appearance of the product differentiation. Because the curve glass surface is more
complex and high cost technology, DisplaySearch is expected that it will mainly used in high order products.
