The part number of this panel is ATP0574-1. • 2.0 DISCRIPTION AND BLOCK DIAGRAM This panel in combination with a control IC chip is used to transfer the co-ordinates of the touched position to the host system (see block diagram on previous page). • 3.0 DRAWING Please see dimension drawing. Definitions of the major dimensions indicated on this diagram: Effective Input Area (A) Area guaranteed to meet all the characteristics detailed in this specification Anti-input Area (C) • An insulating area allowed to protect the touch panel from giving false readings when an enclosure touches the panel. (See fixing instructions) 4.0 CHARACTERISTICS • • 4.1 MECHANICAL Operating Force Hardness of Surface • • 4.2 OPTICAL Transparency Haze 0.05~0.49 N (5 ~ 50gF) Measured with a Silicon Measurement Rod R 8 (Round type 8mm) Silicon Rubber with hardness at 60˚C Pencil hardness 2H minimum against specification JIS K-5400 78% min. measured in the effective input area to JIS K 7105 using a MURAKAMI SHIKISAI KENKYUSHO type IIR 100 meter. 5% type measured in the effective input area using a MURAKAMI SHIKISAI KENKYUSHO type IIR 100 meter with an Anti Glare treated surface. • • 4.3 ELECTRICAL Rated Voltage: Resistance X axis: Resistance Y axis: Switch Bounce (Chattering): Insulation resistance: Dielectric Strength: Linearity: DC 7V max. 300 to 850 Ω (at the connector) 100 to 600 Ω (at the connector) 20ms min when using the silicon rubber measurement rod 10MΩ minimum at 25KV DC No problems when at 25KV DC for 1 minute 2% max. Note 1: Measurement condition of linearity is corrected within the control IC. In general the location accuracy is specified as follows: Actual co-ordinate point - theoretical co-ordinate point = location accuracy. In general a 9 point co-ordinate calibration system is used to adjust the micro controller accuracy. (20 points can be used in combination with an EEPROM design). Page 3 of 7 AZ DISPLAYS, INC.

A word is any Alphabet / Number / Mark. A pen applies a force of 250g. A failure is judged to happen when the current consumption or insulation resistance or dielectric strength are not met as shown in 4.3. The location accuracy with 9 point calibration must be ± 4.4 mm max. Effective input area 9 mm Notes 10mm • • 4.6 FINGER LIFE A finger is simulated by a silicon rubber plunger R8 (Round type 8mm size) hardness 60˚C at 200g at frequency 5Hz. A failure is judged to happen when the current consumption or insulation resistance or dielectric strength are not met as shown in 5.3. The location accuracy with 9 point calibration must be ±4.4 mm max. Operating force is 150g max. Page 4 of 7 AZ DISPLAYS, INC.

Not to be verified form glass side. To be no flaw which is bigger than that shown in the following diagram. The number of flaws is not specified. 3mm 5mm 2mm 2mm • • 6.0 GENERAL POINTS OF CAUTION Touch panels are made of glass, so care must be taken in handling them. Do not stress, pile, bend, lift by the cable or put any stress on the film, for example moving by film face vacuum. In order to clean wring dry a cloth which has been emersed in a natural detergent. DO NOT use any organic solvent, acid or alkali solution. Watch the edge of the panel when cleaning, again for safety reasons. Page 5 of 7 AZ DISPLAYS, INC. • ATP0644-3 6.0 CONNECTION AND MOUNTING The details below indicate the recommended mounting structure for panel and enclosure. The enclosure support to fix the touch panel must be over 1.0mm I width and must be outside the view (Transparent area). Also ensure that the enclosure does not cause miss input by touching the view area. The following diagram shows that the enclosure edge must be between the View area and the guaranteed active area. Ensure space is allocated for the diodes, and we recommend that the material to fix the panel and enclosure is elastic. Special design would be required to stop water ingress. The corners of the touch panel are conductive so do not touch any metal parts after mounting. Detect 1. 2. 3. 4.
