| Electrostatic detection technology
|
GlideSensor™ |
Electrostatic technology utilized in GlidePoint™, GlideSensor™, and Touchmotion™,
detects electrostatic capacitance change less than 1pF caused by the approach of a finger.
GlidePoint™ is made up of electrodes X and Y on a multilayer board, as shown in figure below.
It detects electrostatic capacitance between the electrodes.

| Optical panel molding technology
|
|
Optical simulation and precision mold & molding technologies are
integrated to realize clear, highly translucent optical panels.
Low residual stress molding by mold design based on the flow
analysis is used to realize the optical panel with little birefringence.

Keyboards for Notebook PCs |
Notebook PCs are becoming thinner. In order to achieve comfortable key
operation, it is important to balance stroke, peak load, and the key touch
hysteresis property. ALPS optimized the rubber dome form by
utilizing simulation records from 3D CAD technology, over 200 trial data,
and FEM analysis. The company can create a comfortable key touch in response
to any need.

GlidePoint™ / Low-profile Operation Panels |
 |
 |
|
With Film GlidePoint™, bonding the PET film and the printed wiring
board firmly is essential. ALPS has pursued optimal materials and
succeeded in developing a unique heat-cured resin, which firmly
bonds the PET film and the printed wiring board, securing the film's
silver pattern and the board's copper foil pattern at the same time. |
ALPS gathered all possible knowledge to develop Chip electronic
components that can be surface-mounted on the PET film. The Chip
electronic components are electrically connected to the circuit with
an electrically conductive adhesive and fixed with a UV-cured resin.
By having a consistent, mounted part for fine-pitch through-hole
printing, a wide range of products can be developed. |
| Software technology |
GlidePoint™ |
 |
The IC design technology and software technology of ALPS support
GlidePoint™ development in response to a variety of needs. The
company develops digital/analog-combined ASICs that achieve
both low power consumption and high reliability, as well as developing
the drivers completely within ALPS to respond to customization
in terms of language and functions.
Arranging virtual scroll bars and buttons on the surface of the
touch pad results in a comfortable one-finger operation. |
| Screen printing technology
|
Low-profile
Operation Panels |
Circuit boards applied with films are often employed for small low-profile light products. ALPS
supplies products that employ low-cost PET films instead of the polyimide film typically employed.
Finely pitched pattern printing is achieved by circuit formation technology developed
over past years. High-density wiring equivalent to polyimide film has been achieved, and combined
with through-hole (double-sided) printing technology, even denser wiring is possible.
