 STRONGARM
Industrial Displays |

Additionally, unlike most other display offerings, STRONGARM displays are updated to the current available technology almost as soon as it is released and tested. Users can be assured that what they are purchasing is always state-of-the-art. This fact combined with the fact that STRONGARM maintains their bezel stud pattern as electronics change means that users can replace/upgrade units without the worry that they will need to create new hole patterns and cutouts for the updated device.
Specifications for standard STRONGARM displays are:
Touchscreen options available: Resistive Touchscreen (for 90% of all touchscreen
applications) The resistive touchscreen uses a Surface Acoustic Wave Touchscreen (safest touchscreen for hazardous area applications) The Surface Acoustic Wave Touchscreen has a glass overlay with a grid of transmitting and receiving piezoelectric transducers. The touchscreen controller sends a 5 MHz electrical signal to the transmitting transducer, which converts the signal into ultrasonic waves within the glass. When the screen is touched, a portion of the wave traveling across it is absorbed, thus changing the received signal. The signal is then compared to a stored reference signal, the change recognized, and a coordinate calculated. The process happens independently for both the X and Y axes. By measuring the amount of the signal that is absorbed, a Z-axis is determined. Infrared Touchscreen (for applications where touchscreen
is exposed to extreme abuse) The To learn more about these offerings, please contact Q-mation at 215-675-5800

STRONGARM’s Flat Panel Displays are designed to survive
the most demanding industrial applications. Because the display
elements are built into precision-milled, solid aluminum or
stainless steel bezels, they remain secure and free from stress
no matter the installation.
This insures that the possibility of life-shortening display
deformation is significantly reduced when installing a STRONGARM
display in a panel cut-out or other surface installation where
flex could be an issue.

overlay with a uniform resistive coating. A polyester coversheet
is tightly suspended over the top of the glass, separated by
small, transparent insulating dots. The coversheet has a hard
durable coating on the outer side and a conductive coating on
the inner side. When the screen is touched, the conductive
coating makes electrical contact with the coating on the glass.
The voltages produced are the analog representation of the
position touched. The controller digitizes these voltages and
transmits them to the computer for processing. 
Infrared Touchscreen relies
on the interruption of an IR light grid in front of the display
screen. Integrated into the display bezel is an opto-matrix
frame that contains a row of IR-light emitting diodes (LEDs) and
photo transistors, each mounted on two opposite sides to create
a grid of invisible infrared light. The opto-matrix frame is
isolated from the outside environment by an IR transparent
barrier. The IR controller sequentially pulses the LEDs to
create a grid of IR light beams. When a stylus, such as a
finger, enters the grid, it obstructs the beams. One or more of
the phototransistors detects the absence of light and transmits
a signal that is the X and Y coordinates. Because the infrared
scanning is done in front of the display, a bulletproof, 3/8"
thick polycarbonate window is installed between the IR grid and
the display itself. This window provides a level of
environmental protection for the electronics that is unique to
the infrared touchscreen technology.
