Competitive Advantage:
4 Wire Resistive touch screen is the product of choice for
manufacturers because it can easily produce high resolution of 4096
x 4096 or higher. There are several advantages of this technology.
Resistive touchscreens are low cost as compared to their ‘active’
counterparts.It can be produced to support multi-touch output.
Moreover, a stylus or any pointed object can be utilized to operate
such touchscreens.
technology principle:
The 4 Wire Resitive touchscreen consists of a glass layer with a
conductive coating on top and a polyester top sheet with a
conductive coating on the bottom. The conductive surfaces are held
apart by "spacer dots", usually glass beads that are silk-screened
onto the coated glass.
When a person presses on the top sheet, its conductive side comes
in contact with the conductive side of the glass, effectively
closing a circuit (this is called pressure sensing). The voltage at
the point of contact is read from a wire connected to the top
sheet.It can be touched by finger, gloved finger, leather or stylus
pen.It is inherently of many advantages such as high accuracy,
quick response, drift-free, stable and long durability for a life
time of 1,000,000 times finger touches.
