ChassisTouch FPD Monitors Installation Guide
3M Touch Systems Proprietary Information
For those applications that require flexibility of input, including gloved
hand use, we offer the ChassisTouch in a 5-wire resistive touch screen.
This technology has been tested in a laboratory environment to
withstand 35 million mechanical touches without noticeable degradation
to the surface.
The monitors also feature space saving designs, high resolution, low
radiation, and low power consumption. These qualities make the FPD
touch monitors ideal for applications that require superior color,
resolution, and clarity.
Video Resolution on a Flat-Panel Display
Flat-panel displays, unlike CRTs, are optimized to run at one resolution.
A flat-panel display has discrete points on the display which determine
the exact location of a pixel. Each flat-panel display has an exact
number of pixels associated with it. There is a one-to-one mapping
between the number of pixels and the video addressability, sometimes
called resolution.
Native Video Resolution
A flat-panel display should be used only at the resolution dictated by the
number of pixels on the panel. For example, the 15.1" ChassisTouch
monitors have 1024 pixels across the screen and 768 lines of pixels
down the screen and can accurately display one resolution (1024 x 768)
at full screen. The 17" ChassisTouch monitors have 1280 pixels across
the screen and 1024 lines of pixels down the screen and can accurately
display one resolution (1280 x 1024) at full screen.
Options for Using Other Video Resolutions
The 3M Touch Systems 15.1" and 17" FPD monitors support all
standard resolutions up to their respective native resolution for monitor
setup. Many video cards initially display a screen image at the SVGA
or VGA resolution. By supporting these resolutions, the monitor can
display the desktop controls that let you change to the optimal resolution
of either 1024 x 768 (15.1") or 1280 x 1024 (17").
