The potential interference between the degaussing coil and the touchscreen must also be evaluated. The coil will usually fit between the touchscreen and the inside surface of the bezel, as there is typically a natural cavity for it. If there is not enough space for the coil, you may have to provide additional setback for the CRT. It may also be possible to relocate the coil to the bell side of the CRT. Normally, this does not significantly reduce the coil’s effectiveness. However, you must determine this by inspecting the display for color problems after reassembly.

•Check for adequate clearance of the transducers and the cable from the bezel

structure. If the position of the cable causes difficulty, the touchscreen may be rotated 180° (only if the touchscreen is sealed and using Elo drivers).The preferred orientation of the IntelliTouch touchscreen is with the cable exiting from the right side, when viewed from the front of the display. Rotation will cause an inversion of the output coordinates, which will be compensated for automatically by Elo driver software, but perhaps not by other drivers. (Flat touchscreens should have the reflector stripes on the side facing the user.)

Verify Touchscreen Fit

1Check to ensure touchscreen dimensions match CRT display. Place the touchscreen on the face of the tube to see that the face of the CRT and touchscreen are about the same size, and that the radius of curvature (ROC) of each surface matches well. If both of these conditions are not met, you may not have the proper touchscreen for the display. Most color displays have standard size CRT's with standard ROC's, and Elo has touchscreens for most of them.

2Determine if the touchscreen will fit in the bezel without modifications to the

bezel. The bezel should not touch the transducers and should land in the sealing area, not on the reflector strips.2 Modifications, if necessary, should be done without compromising the mechanical integrity of the display. Also see Bezel Design section for recommendations.

Note: If the touchscreen will not fit flush against the lip of the bezel, do not force it. An interference fit between the edge of an IntelliTouch touchscreen and some of the plastic ribs found in display bezels can pinch and break the small wires which carry the signals along the edges of the touchscreen or even result in fracture of the glass after reassembly.

2.Clearance around the transducers should be 1-2 mm clearance above transducers (to prevent dampening vibration, electrical short or breakage), and 3-5 mm around transducers. Allow for

manufacturing variances of touch screen and integration. If the position of the cable causes difficulty, the touchscreen may be rotated 180° . The preferred orientation of the IntelliTouch touchscreen is with the cable exiting from the right side, when viewed from the front of the display. Rotation will cause an inversion of the output coordinates, which will be compensated for automatically by Elo driver software, but perhaps not by other drivers. (Flat touchscreens should have the reflector stripes on the side facing the user.)
