How It Works? |
| |
Resistive technology is suitable for variety of applications and environments.Resistive Touch Panel is two transparent resistive ITO layers (conductive and resistive layers) consisting of a sensor. |
| |
|
| • |
4-wire analog resistive touch panel |
| |
Each ITO layer consists of two Conductive Bars.? When touch pressure
is inducted, then voltage is applied across the screen in the Y direction
and presses two layers together. The voltage can be contacted with
one of the X electrodes. The result of the touch creates a point, so the Y
coordinate can be determined.
Benefits
- Low cost
- Broad input flexibility.
- Dust-proof and liquid resistance.
- High accuracy and durability.

5-wire analog resistive touch panel |
| |
5-wire resistive has 4 linearization patterns and 4 electrodes (circular).
Linearization pattern and electrodes are resided in the same ITO layer.
Then 4-side of linearization pattern is called fifth wire.
Benefits
- High resolution and sensitivity.
- Broad input flexibility.
- Dust-proof and liquid resistance.
- High accuracy and durability.
- Long lifetime. (almost ten times of 4-wire resistive panel)

8-wire analog resistive touch panel |
| |
Compare a 4-wire touch screen with 8-wire touch screen; an 8-wire touch screen has more sense wires to the end of each conductive bar.
These sense wires calibrate out any voltage offset by the wiring or drive circuitry.
Benefits
- High resolution and sensitivity.
- Broad input flexibility.
- Dust-proof and liquid resistance.
- High accuracy and durability.
