• 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)

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).

Note taking life:
Input life :
100,000 words minimum
1,000,000 times minimum
Note 1:
Words are written in the notes area and the size of the word is 7.5mm x 6.75mm. 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.

• • 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.

• • 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.

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.
