C H A P TER 1 C HAP TER 1INTELLITOUCH TECHNOLOGY Introduction The IntelliTouch system has three main components: a clear solid glass screen formed to match the shape of a display, a sophisticated electronic controller, and a software driver. The IntelliTouch touchscreen is based on patented surface wave technology. Surface waves are mechanical waves that propagate in the surface of materials such as glass. The touchscreen may be a flat glass panel or a segment of a sphere or cylindrical gla

The IntelliTouch Touchscreen The IntelliTouch surface wave technology touchscreen consists of a glass panel molded to the shape of a display's face. Each axis of the touchscreen panel has a transmitting and receiving piezoelectric transducer, and sets of reflector stripes. See Figure 2.3 on page 10 for details on the construction of an IntelliTouch touchscreen. Figure 1.1 IntelliTouch Touchscreen Surface wave energy is generated by the transmitting transducers mounted in the corners of the

The IntelliTouch Controller The IntelliTouch controller provides the drive signal for the touchscreen, converts the received analog signals into digital touch coordinates, and sends these coordinates to the computer. The controller detects touches by comparing received signals to a reference waveform acquired when the touchscreen is in an untouched condition. The IntelliTouch controller detects dirt, dust particles, scratches and other contaminants on the screen and “learns around” them. It

Driver Software Elo driver software provides a consistent software interface among all Elo touchscreens and controllers. The driver software scales the absolute coordinates received from the touchscreen controller into translated screen coordinates, using the calibration points obtained with the video alignment program included with the driver software. The driver also performs other operations as directed by the application. Elo provides driver programs for the DOS, Windows 3.1, Windows CE

C H A P TER 2 C HAP TER 2COMPONENT INSTALLATION This chapter outlines the procedures for installing touchscreen components that will convert your monitor into a touchmonitor. Details are given on mounting the touchscreen, controller, and connecting cables. Safety Information WARNING The touchscreen installation procedure outlined in this chapter may require exposure to high-voltage components and handling of the CRT. This procedure can be dangerous and an accident is potentially lethal. Ther

Protective Clothing Wear safety glasses, gloves, a rubber apron, and heavy protective clothing for any portion of this procedure that involves handling or working near the CRT. Getting Started There are two types of display technologies, CRT displays and LCD displays. IntelliTouch touchscreens are available for most displays, however each display may pose unique installation issues. If, after reading these instructions, you need further assistance please contact Elo Application Engineering f

To prevent touchscreen breakage, there should be a compliant gasket between the back of the touchscreen and the front of the display to allow for variation in the surfaces when assembling. A gap is also required between the touchscreen and the face of an LCD display to prevent damage to the display. Unlike CRT's, plasma, EL, and backlit LCD displays may be a significant source of heat. The situation may be more significant if the unit is sealed. Any installation must avoid heat rise tha

Cutting these ribs and struts does not usually cause difficulties, although the stiffness of the bezel may be reduced slightly. Try not to cut into the posts for the CRT attachment screws.
