capacitive touch display incorporating a 4.3”, 480 x 272 (WQVGA) LCD with a LED backlight. The touch portion of the module consists of a glass sensor optically bonded to 1.1 mm cover glass with an FPC (Flexible Printed Circuit) attached for communicating with the touch panel. The touch panel assembly (sensor plus cover glass) is bonded to the LCD frame. Interfacing to the touch panel is done through an I2C or USB protocol communicating with the touch controller incorporated onto the FPC. The touch panel can provide accurate and responsive touch performance capable of sensing up to two unambiguous points. The integrated configuration of the Fusion touch display gives the end customer the ability to develop a touch user interface with a minimum of time and design effort that is instantly recognizable by the greater public. 2 TOUCH MODULE 2.1 GENERAL SPECIFICATIONS Table 1 - Touch Performance Specification Parameter Center Linearity Within 5mm of the edge Touch Sensor Resolution Value Unit Remarks mm Note 1, Appendix A 1 2 480x272 Single Touch 80 Dual Touch 55 Minimum Touch Diameter Detectable Resolution Serviced Interrupts/second Note 2, Appendix A 5 mm Note 4, Appendix A Minimum Detectable Separation 15 mm Number of unique detectable concurrent touches 2 Report Rate Page 1 TPK America LLC Confidential F04E-0101 2.2 ELECTRICAL – TOUCH PANEL When using the I2C interface these voltages and current are applicable.

The 2 interfaces are I2C or USB. 3.2 I2C INTERFACE The I2C interface of the touch module is a NXP compliant I2C interface (V2.1). The Fusion 4 Touch module uses an Atmel MaxTouch Touch controller integrated circuit. Touch Revolution provides reference drivers for developers to use when designing systems to communicate with the Fusion 4. For detailed information about the Touch controller please check directly with Atmel. TR is not able to distribute detailed information about Atmel touch controller without a 3-Way NDA. The reference drivers are available from the Touch Revolution webpage or by contacting support@touchrev.com. The Touch module uses 0x4A or 0x4B as its 7 bit I2C slave address. The I2C interface has 3.3K Ohm resistors pulling the SDA and SCL lines up to VCC (3.3V). 3.3 USB INTERFACE The Fusion 4 USB interface adheres to the Device Class Definition for Human Interface Devices (HID) version 1.11. The module reports as a Digitizer. It is compliant to the Windows 7 Digitizer Driver Specification1. The Fusion 4 is compatible to USB 2.0 FS device standards. The Fusion 4 USB device vendor ID and product ID definition are as follows: USB VID is: 0x1391, the PID is: 0x2112 The Fusion 4 maximum width in pixels is 4096. The Fusion 4 maximum height in pixels is 4096. The Fusion 4 maximum number of touches is 2. 1 The Full Windows 7 Digitizer Driver Specification can be found online at http://www.microsoft.com/whdc/device/input/DigitizerDrvs_touch.mspx Page 6 TPK America LLC Confidential F04E-0101 In addition to the basic digitizer function the Fusion 4 USB interface also supports a vendor command function that can be used to configure and control the touch panel. The definition of these functions can be found in Fusion USB Touch Configuration Controls document. The basic functionality includes the ability to reset the touch panel controller, perform specific i2c transfers, and perform touch firmware upgrades. 3.4 SWITCHING BETWEEN I2C AND USB The touch panel can only communicate via either USB or I2C. It cannot communicate on both interfaces simultaneously. To communicate via USB the VBUS pin must be connected to +5V. This will deactivate the I2C interface. Using the I2C pins while in USB mode will cause the device to malfunction. To communicate via I2C the VBUS signal must not be connected. It must be left floating. 3.5 TOUCH PANEL CONNECTOR The recommended touch panel connector is: FCI P/N SFV10R-1STE1HLF or equivalent. The pinout for the FCI connector is as noted in the following table Table 7 - Touch Panel Connector Pinout – Refer to Mechanical Drawings for Pin 1 Orientation Pin No. Symbol Description 1 2 3 4 5 6 7 8 9 10 VCC RST INT SDA SCL GND D+ DVBUS GND Power Reset Interrupt I2C Data I2C Clock Ground USB Positive USB Negative USB Power Ground Required Required for USB for I2C Yes Yes No Yes No Yes No Yes No Yes Yes Yes Yes No Yes No Yes NC Yes Yes Page 7 TPK America LLC Confidential F04E-0101 3.6          SIGNAL DEFINITIONS VCC 3.3V Power supply for the touch controller (required with and without USB).

Page 21 TPK America LLC Confidential F04E-0101 6 BARCODE 6.1 DESCRIPTION Every Fusion touch panel contains a unique 2 dimensional barcode. This barcode is used for serial number identification and part specification. 6.2 LOCATION The barcode is located on the flex tail as pictured below. Barcode label Figure 12 – Barcode Label Area (Rear View of Module Shown) 6.3 CONTENTS The barcode contains the unit serial number, Touch Revolution part number, and touch firmware release version. Page 22 TPK America LLC Confidential F04E-0101 7 HANDLING AND PRECAUTIONS 7.1 DISASSEMBLY OR MODIFICATION Do not disassemble or modify the touch display. This may cause damage to sensitive components and may cause dust or scratches between the touch sensor and LCD. Touch Revolution’s warranty will be void if the unit has been disassembled or modified. 7.2 UV EXPOSURE Long term exposure to sunlight can affect the optical performance of the LCD. 7.3 CLEANING The cover glass should be cleaned using a soft, lint free cloth. It is recommended that either an ammonia based glass cleaner (e.g. Windex) or a 50:50 solution of isopropyl alcohol and water be used for cleaning the sensor. Apply the cleaning solution to the cloth and gently wipe the surface of the sensor. To help minimize streaking, wipe in a circular motion starting in the center and working outwards. 7.4 STATIC ELECTRICITY Since the LCD and Touch panel use CMOS ICs, the device is susceptible to electrostatic discharge. Please use appropriate grounding when handling these modules. 7.5 ABSOLUTE MAXIMUM RATINGS Do not exceed the absolute maximum rating values for the supply voltages and environmental conditions to prevent damage to the touch display. 7.6 BREAKAGE If the LCD panel breaks be careful not to touch any liquid crystal material that may spill. Immediately rinse with water if liquid crystal material comes in contact with skin. 7.7 INPUT VOLTAGES Turn off the power supply before handling and/or inserting signal or power cables to the touch module. Page 23 TPK America LLC Confidential F04E-0101 7.8 STATIC IMAGES If fixed images are displayed for a long period of time, an afterimage is likely to occur. 7.9 OUTGASSING Do not store or use the touch module in an environment where caustic materials such as reagents, solvents, adhesives, and resins are present. Outgassing of these materials can damage the polarizer and ACF connections.

The distance between the actual location of the center of the slug and the reported location shall be less than or equal to the maximum specified error. Note 2: Report Rate Report rate is the maximum rate at which touch data is returned to the host PC. The report rate may drop to 30 interrupts/second for some unique two finger touch combinations. Note 3: Response Time Response time is the time elapsed between the first touch and interrupt assuming touch is in active mode Note 4: Minimum Touch Diameter The minimum touch diameter is the minimum diameter of a copper slug that is needed to record a touch.
