GENERAL DESCRIPTION
Vishay Dale^® TIP products are infrared touch panels designed
to fit most flat panel display technologies. The touch panels
consist of infrared emitters and detectors, scanning
electronics, a microprocessor based controller, a bezel and
optical filter assembly and hardware to mount the touch panel
assembly to the flat panel display.
These touch panels are ideal for many applications including
medical instrumentation, machine or process controllers, point
of sale devices, public information displays, banking terminals
and military.
Each panel has infrared LED emitters and phototransistors
along the X and Y axis, forming a grid of infrared light beams
across the face of the display. The first two numbers of the TIP
"matrix" number specify the number of X axis (vertical) beams,
and the last two numbers specify the number of Y (horizontal)
beams. The controller scans the emitter/detector pairs one at
a time and determines whether both X and Y beams are
blocked, indicating that a finger or stylus is present. (When
beams are blocked on only one axis, they are ignored and not
reported.) The controller determines the coordinates of the
touch point and reports it to the host computer. By
interpolating, a "virtual" beam between two physical beams,
the number of touch points on each axis is effectively doubled.
When an odd number of beams along either axis are blocked,
the coordinate of the center physical beam is reported. When
an even number of beams are blocked, the coordinate of the
virtual beam in the center of the blocked beams is calculated
and reported.
Vishay Dale's^® TIP touch panels have a unique patented scan-
ning and logic system that make them virtually immune to most
lighting environments. The touch controller supports ENTER,
EXIT, CONTINUOUS and TRACKING report modes or combi-
nations of these modes. The controller also has a beeper out-
put. Hardware handshaking, software handshaking, baud rates,
auto-baud and X, Y coordinate invert features are jumper
selected. The user initializes the desired report modes and
requests reports when needed.
Several optical filters are standard to provide the most cost
effective filter for each application. "Non-standard" filters may
be specified as well. The filter increases the contrast ratio of
the display and protects the display face and electronics. Dale^®
can assist in recommending the optimum filter based on years
of experience as a display manufacturer. The perimeter of the
filter is bonded to the bezel, and a bezel to front panel gasket
is included to provide a splash proof seal. Optional PC based
software provides simple touch panel integration (see
ordering instructions).
