ATP0644-3 Datasheet, PDF (3/7 Pages) AZ Displays – SPECIFICATIONS FOR STANDARD RESISTIVE TOUCH PANEL

AZ DISPLAYS, INC.
ATP0644-3
• DETAILED SPECIFICATION
• 1.0 APPLICATION
This specification applies to the 5.7" (inch) standard TOUCH PANEL (Pen/Finger type).
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

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).
