Applications:
4 Wire Resistive touchscreen is an outstanding high quality
product, suitable for low cost solution. Suitablefor
GPS, medical, Light industrial ,Pos,Portable sport devices, Access
control terminals, Portable medical devices,
LCD and LED touch monitors,All-In-One ,Home appliances and other
fields.
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.
