A 5-Wire Resistive touchscreen is coated with a thin
metallic electrically conductive and resistive layer
that causes a change in the electrical current which is
registered as a touch even and sent to the controller
for processing. Resistive touch panels are generally
more affordable but offer only 75% clarity and layer can
be damaged by sharp objects. Resistive touchscreens are
not affected by outside elements such as dust or water.
Generally in the analogue resistive technology, top
layer acts as a probe detecting the other axis(X or Y)
and this structure, as the top layer gets worn out, may
degrade the linearity and the accuracy of detecting
coordinates with long time use. 5-wire resistive
technology is to complement these weak points and here
are its structure and the operating principles.
| As shown above, 5-wire technology utilizes
the bottom substrate for both X & Y axes'
potential measurements. All the electrodes
are placed on the bottom layer and the top
layer acts only as a voltage measuring
probe. This basic design difference of the
structure leads to much more durable and
stable characteristics and it works properly
even with non-uniformity in the top layer's
conductive coating. |
