The following features are optional.
Dimming
To lower the brightness to minimum on a monitor without sacrificing contrast values. This is
especially useful on ships during night use in order to keep night vision intact.
Sunlight readable
Polarizing filter that is applied on top of the LCD display, increases color saturation and decreases
reflections on the panel in environments where strong sunlight is common.
Marine functionality
The following features are optional.
Surface Acoustic Wave (SAW)
Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen
panel. When the panel is touched, a portion of the wave is absorbed. This change in the ultrasonic
waves registers the position of the touch event.
Projected Capacitive Touch (PCAP)
Projected Capacitive Touch (PCAP) are made up of a matrix of rows and columns of conductive
material, layered on sheets of glass. Voltage applied to this grid creates a uniform electrostatic
field, which can be measured. When a conductive object, such as a finger, comes into contact
with a PCAP panel, it distorts the local electrostatic field at that point.This is measurable as a
change in capacitance. If a finger bridges the gap between two of the ”tracks,” the charge field is
further interrupted and detected by the controller. The capacitance can be changed and measured
at every individual point on the grid (intersection). Therefore, this system is able to accurately
track touches. Due to the top layer of a PCAP being glass, it is a more robust solution than less
costly resistive touch technology. It is possible for a PCAP system to sense a passive stylus or
gloved fingers.
