ATP0574-1
⢠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
⢠⢠4.1 MECHANICAL
Operating Force
0.05~0.49 N (5 ~ 50gF) Measured with a Silicon Measurement Rod R 8
(Round type 8mm) Silicon Rubber with hardness at 60ËC
Hardness of Surface Pencil hardness 2H minimum against specification JIS K-5400
⢠⢠4.2 OPTICAL
Transparency
78% min. measured in the effective input area to JIS K 7105 using a
MURAKAMI SHIKISAI KENKYUSHO type IIR 100 meter.
Haze
⢠⢠4.3 ELECTRICAL
5% type measured in the effective input area using a MURAKAMI
SHIKISAI KENKYUSHO type IIR 100 meter with an Anti Glare treated
surface.
Rated Voltage:
Resistance X axis:
Resistance Y axis:
Switch Bounce (Chattering):

Dielectric Strength:
Linearity:
DC 7V max.
300 to 850 ⦠(at the connector)
100 to 600 ⦠(at the connector)
20ms min when using the silicon rubber measurement rod
10M⦠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).
