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.
