Touchscreen FAQ
1. What are the main applications for PenMount PCI product?
We are focusing on industry and business fields which applications request a durable and a total solution product.
2. What is the construction of AMT PCI touch sensors?
The current AMT PCI sensor constructions are either two or three layers of ITO film laminated to the top glass. We called it the GFF or GFFF type.
3. What is the purpose for the rear side conductive layer of PCI touch?
The bottom layer conductive film of PCI touch panel is for shielding purpose, to prevent the system or LCD noise to affect the controller signal detecting.
4. What is the bending radius for PCI tail?
Tails bend radius is 1mm.
5. What is the difference between cover-glass and décor-glass?
Cover glass is the pure transparent glass used for AMT standard PCI (GFFF).
Décor glass is a cover glass which has an additional color printing on the backside (e.g. black frame).
6. What is the surface hardness of PCI?
PCI cover glass has a clear surface with a hardness of MOHS 5.
7. Does PenMount PCI have EMI design?
Yes, all PenMount PCI touch sensor is design with EMI shielding to avoid the interference from LCD or own system .
8. Will AMT release the PCI touch sensor with COF design?
Yes, the 7” PCI with COF tail is ready; there will come 4.3” and 5.7” PCI with COF tail in Q2 of 2012.
9. What are the thicknesses of cover glass that AMT PCI Sensors can support?
- S Series (P3002-3.5” / P3003-4.3”): up to 1.8mm
- MS-1 Series (P3004-5.7” / P3005-6.4” / P3006-7”): up to 2.8mm
- MS-2 Series (P3012-7”): up to 5mm
- ML Series (P3007-8.4” / P3008-10.4”): up to 5mm
- L Series (P3009-12.1” / P3013-15”): up to 2.8mm
10. Can PenMount PCI solution detect multiple touches?
Yes, concurrent dual touches for today’s PCI product.
11. How many touch does PenMount PCI support?
PenMount PCI touch solutions support dual touch and gestures.
12. Does PenMount PCI solution operate on Windows 7?
Yes, the Windows 7 inbox driver is compatible with PenMount PCI.
13. How long/short can the tail be on PCI touch?
Shorter is better! A short tail reduces interferences between the electronic components.
14. What kind of PCI sensor surface coating does AMT have?
Clear, AG or AR.
15. What’s the sensor light transmission rate on 1.1mm clear surface glass?
87% +/- 3%
16. Can projected capacitive touch screen be operated when there is liquid on the surface?
Sometimes liquid on the surface of a projected capacitive touch screen might cause malfunction, which is a limit yet to be overcome for projected capacitive touch technology.
17. Can I operate a projected capacitive touch screen with gloved fingers?
AMT PCI touch panel with PenMount PCI control board are able to support gloved finger operation by certain kinds of gloves: latex glove for medical and clean room, household latex glove, cotton glove, work glove.
18. What’s the maximum size that PenMount projected capacitive controller supports?
From 3”to 15”projected capacitive touch panels are supported by PenMount projected capacitive controllers. Larger sizes are under development.
