TIP
Vishay Dale
GENERAL DESCRIPTION
Each Vishay Dale^® touch panel has infrared LED emitters and
detectors 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
vertical beams and the last two numbers specify the number
of 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 to the host.) The controller determines the
coordinates of the touch point and reports them 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 is blocked, the coordinate of the center physical
beam is reported. When an even number of beams is blocked,
the coordinate of the virtual beam in the center of the blocked
beams is calculated and reported. The touch controller
supports ENTER, EXIT, CONTINUOUS and TRACKING
report modes or combinations of these modes. The controller
also has a beeper output. Hardware handshaking, software
handshaking, baud rates and auto-baud 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.
Vishay 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 includedto provide a splash proof seal.
