A Brief of PenMount Projected Capacitive Touch Controller Products
01/12/2012 | Bulletin No: PMY12001
While welcoming the New Year, PenMount wishes you a Happy, Healthy and Prosperous Year of 2012!
PenMount Bulletin will be issued on Thursday of the second week of each month from this year. In this issue, the up-to-date development of PenMount projected capacitive touch (PCI) control is briefly presented. After 3 years continuous research and development since 2008, the PCI controller for different touch screen sizes are now ready for customers’ applications. Inherited the spirit of full-driver-support in PenMount resistive touch controller family, more drivers for PCI are to be in place soon.
For PCI touch, in every 4-8mm there is a so-called ‘Drive’ or ‘Sense’ line (or pattern) on the touch screen. The size of a touch screen is therefore the major factor to decide the number of ‘Drive’ or ‘Sense’ to connect to PCI controllers. The table below shows the four controller boards rolled out during last year:
Remark：PCI（Projected Capacitive Input ）
The thickness of the cover glass of PCI can be thinner from 0.4mm up to 2.8mm. This gives the great opportunity of using gloves (medical sanitary, anti-static or that with material in cotton) for single or two fingers touching.
Multiple interfaces including USB/RS232/ I²C/SPI are ready for selection on PenMount PCI control board. Drivers for Windows XP/Vista/7 and Windows Embedded CE are supported. For Linux or Android, the driver in source format is offered for customers own development.
As we have mentioned above, the size of the touch screen is the major factor of selecting the right PenMount PCI controllers. There are still others which also contribute to the proper PCI operation and they are Drive-Sense pin-assignment, thickness of the cover lens, IO interface and others. PenMount PCI controller maintains a set of parameters to adjust the overall performance, e.g. speed and sensitivity. Customers may also check through PCIMset, an in-house developed tool offered by PenMount, to manipulate the parameters for the best PCI control.
It might be necessary for customers to upgrade PenMount PCI firmware in the field. ‘Pmfu’ (PenMount Field Update) is exactly the tool to accomplish the field update to keep the controller the most updated and compatible. You may contact our sales people for more detail.
