Introduction C HAPTER CHAPTER 2ABOUT ACCUTOUCH TOUCHSCREENS The Elo AccuTouch touchscreen system consists of a touchscreen and an electronic touchscreen controller. The AccuTouch touchscreen is based on patented resistive technology. The touchscreen may be a flat, spherical, or cylindrical and is installed over the face of the display. Since its shape matches that of the display face, an AccuTouch touchscreen has excellent clarity and minimal parallax. AccuTouch features include: Proven resistive technology. High accuracy and fast response. Hard-coated surface for scratch protection. Clear finish for maximum image clarity, or antiglare finish for reflection control. Pressure-activated by a finger, fingernail, gloved hand, or any stylus. Large selection of standard sizes for spherical, and flat displays. Custom sizes for OEM quantities. Easily sealed to enclosure for harsh environment protection. Operates even when wet. 2-17
The AccuTouch Touchscreen The AccuTouch resistive touchscreen consists of a glass panel molded to the precise shape of a display's face. A scratch-resistant, hard-coated plastic cover sheet is suspended over the surface of the glass by less than one-thousandth of an inch with tiny separator dots. The cover sheet may be clear for best image clarity or have an antiglare finish. For optimum optical performance, the touchscreen may be optically bonded to the cathode ray tube (CRT) face. See figure 2-1 for details on the construction of an AccuTouch touchscreen. The glass is coated with a transparent uniform resistive coating, and the cover sheet has a conductive coating. With a light touch on the cover sheet, the conductive inner surface of the plastic makes contact with the resistive coating on the glass. There is an electrical drive connection to each of the four corners of the resistive coating, and a pickup connection to the coating on the cover sheet. When the proper DC voltages are applied to the drive connections, the voltage at the pickup connection is proportional to the position of the touch. Refer to the Elo web site, www.elotouch.com, for more information on how the AccuTouch resistive touchscreen operates. Figure 2.1 AccuTouch Touchscreen 2-18 Elo Entuitive Touchmonitor
