GENERAL DESCRIPTION

Each Vishay Dale

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

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.
