Page 13: Intellitouch Technology
H A P T E R NTELLI OUCH ECHNOLOGY HAPTER 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. -
Page 14: The Intellitouch Touchscreen
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. -
Page 15: The Intellitouch Controller
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. -
Page 16: Driver Software
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. -
Page 17: Component Installation
H A P T E R OMPONENT NSTALLATION HAPTER 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. -
Page 18: Protective Clothing
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. -
Page 19: Bezel Design
• 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. •... -
Page 20: Crt Integration
On bezel and cabinet, choose paint finish and/or surface texture so fingerprints do not show Figure 2.2 Bezel edge It may be necessary to cut ribs and struts inside the bezel. Cutting these ribs and struts does not usually cause difficulties, although the stiffness of the bezel may be reduced slightly. -
Page 21: Definition Of Terms
Definition of Terms: MONITOR: The term "monitor" refers only to the monitor, television, or other display that is to be integrated. BEZEL: The term “bezel” refers to a specific part of the molded plastic cabinet of the monitor. The bezel is the part that covers the front of the CRT and separates it from the rear case. -
Page 22: Summary Of Installation Steps
Summary of Installation Steps The CRT installation process consists of the following steps: Incoming inspection Disassembling the monitor Attaching the touchscreen to the CRT Installing the controller Routing the touchscreen cables Reassembling the monitor Sealing the monitor Specific compatibility may not be confirmed until well into the installation. IntelliTouch touchscreens can be installed on most types of CRT displays. -
Page 23: Incoming Inspection
Incoming Inspection Unpacking the Touchscreen Handle the touchscreen with care. Note the transducers in the corners are especially fragile. Note the location of the transducers and wiring. If any of these are accidentally broken during handling or installation, or if a wire is pulled loose, the touchscreen will not operate. -
Page 24: Remove The Back Case
Remove the Back Case Figure 2.3 on page 10 shows the typical construction of a 15-inch display. Disassembly usually starts with removal of the back case. For assistance with disassembly, consult your particular manufacturer's service manual. Carefully lay the monitor on its face on the padded work surface and remove the screws that attach the back case to the bezel or frame. -
Page 25: Remove The Electronic Chassis
It may be necessary to remove some sheet metal to gain access to the anode lead—be very careful to do this without making contact to the anode lead itself. Carefully discharge the CRT using the following procedure: Connect a clip lead or a heavy-gauge wire to the mounting ears or the spring- tensioned ground strap. - Page 26 • Various cables connected to the power switch, pilot light, front panel controls, etc. Other cables may have to be unplugged from the electronic chassis. The need for this may not be apparent until the chassis is removed, as instructed below. Another preliminary step in determining touchscreen/display compatibility should be performed at this point.
-
Page 27: Remove The Crt
Remove the CRT Removal of the CRT is next. Prepare a soft surface to set the CRT on. Remove the screws attaching the CRT to the bezel, and then remove the CRT. Do not lift or carry the CRT by the neck or yoke assembly. Avoid contact with the anode button, which may still have some residual charge on it, (you may wish to discharge it again at this point). -
Page 28: Verify Touchscreen Fit
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. - Page 29 It may be necessary to cut ribs and struts inside the bezel. 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.
-
Page 30: Attaching The Touchscreen
Attaching the Touchscreen Once you have verified all dimensions and checked that the bezel has plenty of clearance around the transducers and lands inside the sealing area, you are ready to install the touchscreen. Check room for cable routing: • Route away from noise sources (flyback transformer, power supply, yoke, high voltage lead, etc.) Cable can be on either side. -
Page 31: Proper Placement Of Adhesive Tape To The Touchscreen
Use two layers of the double-sided adhesive tape to achieve a total thickness of 1/16-inch (2 mm). While specific touchscreen and CRT combinations may allow the use of thinner materials, 1/16-inch (2 mm) is generally necessary to allow for variations in ROC between the two glass surfaces. Review the fit between the touchscreen and the CRT before applying the tape. -
Page 32: Spacing The Crt From The Bezel
When you have a good feel for the placement of the touchscreen, clean the back side of the touchscreen and the face of the CRT again. Avoid all contact between the cleaning solution and the mounting materials as the cleaner may cause the mounting materials to eventually release from the glass. -
Page 33: Installing The Controller
During the spacer selection process, you may have to install the CRT with the touchscreen attached in the bezel several times. To prevent the CRT from dislodging the spacers, temporarily insert plastic tie wraps or toothpicks as guides in the mounting post holes. After selecting the correct spacers, discard the guides and fix the spacers more securely in place with the adhesive "doughnuts"... -

Page 95: Glossary
Autosizing-True autosizing occurs when a monitor can maintain a constant image size across different video modes. Two common ways of achieving autosizing are mode sensing, pre-programmed factory settings and user defined modes. Bandwidth-The range of frequencies over which the video display’s electronics can respond. - Page 96 DPMS™-Display Power Management Signaling standard. VESA® standard which ensures that monitor and video manufacturers produce power saving products that work together. DQ-DAF-Double-Quadruple Dynamic Astigmatism and Focus. The basic technology of the DQ-DAF is the same as the DAF. The DQ-DAF has two sets of quadruple lenses in addition to the main focus lens.
- Page 97 Invar-Shadow Mask-A special type of shadow mask that is made out of Invar, an alloy that is able to withstand high temperature generated by the electron beam. The Invar shadow mask allows the CRT to generate a brighter image than the conventional shadow mask.
- Page 98 MPR-II-The radiation emission standard published by the Swedish National Board for Measurement and testing. Multi-Frequency vs Fixed Frequency-Fixed frequency monitors can only sync on one horizontal scan rate (e.g. 31.5 kHz). Most of this type of monitors are VGA only. There are two basic types of multi-frequency monitors: the tri or quad sync multi-frequency monitor, and the variable multi-frequency monitor.
- Page 99 Primary Colors-In light (and in monitors, which produce light) they are the basic colors-red, green and blue-that can be added together to create any other color. Raster Area-The area of the CRT which has the ability to display a video image.
- Page 100 Swim-An image should be rock-steady on the monitor screen. Swim, like similar characteristics jitter and drift, is a measure of how much an on-screen image wavers over a given time. Triad-A triad contains three phosphor filled dots-one red, one green and one blue-arranged in a triangular fashion.
