screen usually refers to the contact or touch on the display of the device by a
finger or hand. LCD touch screen monitors are also sensitive to other passive
objects, such as a stylus, however when the sensed object is active, as with a
light pen, the term touch screen is usually not applicable. To be able to
directly interact with an LCD touch screen monitor will indicate the presence of
a touch screen. LCD touch screen monitors have two main attributes. One is to
interact with the display directly, without the use of keyboard or mouse, and
the second no intermediate device is required such as a stylus, which needs to
be held in the hand. LCD touch screen monitors can be used with computers, or as
terminals to networks. Touch screen monitors first emerged from academic and
research laboratories in the late 1960s. LCD touch screen monitors have wide
applications, such as medical, industrial, POS, kiosks, transportation,
automation and gaming.
