INTEGRATING THE SENSOR
To integrate the sensor, you will require a suitably sized LCD with a display area close to the
active area of the sensor, as shown in Figure 5 (the active area of the sensor can be found on
the corresponding Zytronic sensor drawing). Where possible, it is advisable to have the
active area of the sensor 2-3 mm oversized on all four edges in relation to the LCD display
area. This will allow for some misalignment during integration.
FIGURE 5 SUITABLE LCD TO MOUNT THE SENSOR TO
Foam gasket should be used around the perimeter of the LCD to provide an air gap between
the LCD face and the rear of the sensor, as shown in Figure 6. This air gap is necessary to
prevent excessive electrical noise from the LCD causing interference to the sensor.
Guidelines for the required thickness of the gasket can be seen in the table below and are
sufficient for most LCDs. Some LCDs with very high levels of noise may require greater
spacing which would need to be determined by testing.
