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