Features of 4-Wire Resistive TP:


Low Cost

  • The most important application of resistive touch panels, especially 4-wire ones, is with small displays in the low-cost sector.

Ease of Interfacing

  • With low-cost sector displays, it should be relatively easy to implement a Touch Panel solution. In such cases a low resolution Analogue to Digital converter is all that is needed to control and interface with them.

Touch Sensitivity

  • Touch panel may be activated by finger, nail, stylus, credit card, key or gloved hand. It is not affected by dirt, dust, water or chemical solvents.


Features of 5-Wire Resistive TP:


Stability and Reliability

  • The 5-wire resistive touch panel uses the stable bottom layer for both X- and Y- axis measurements.

  • Top ITO PET acts only as a voltage-measuring probe. Touch panel works properly even with non-uniformity or scratches in the coversheet's conductive coating.

  • With the advantages of high temperature process, products are optimized in material, structure and production; they are assured to have extraordinary stability, durability and reliability in electrical, mechanical, optical performance.

Touch Sensitivity

  • Touch may be activated by finger, nail, stylus, credit card, key or gloved hand. It is not affected by dirt, dust, water or chemical solvents.

Flexible in Design

  • Capable of providing sizes from 2.5” to 23”, 0" aspect ratio, and slim perimeter products. To overcome the weaknesses in abrasion and sunlight readability. Can supply Glass/Glass and Circular Polarized resistive touch panels to meet specific requirements.
