SPECIFICATIONS FOR STANDARD RESISITIVE TOUCH PANEL

AZ Displays 

AZ DISPLAYS, INC.

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 60˚C

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):

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).
