Overview:
The GreenTouch 4wire resistive touch screen uses the proven four-wire resistance technology, which is the best choice for high reliability, input flexibility and superior anti-interference. Touch is achieved by pressing the sensor, suitable for a variety of strong magnetic fields, strong electric fields , complex lighting and other complex operations. The 4wire resistive touch screen with EETI control card or FangXian control card can run various operating systems perfectly, and can provide products of various sizes and customized product selection.

   4 wire resistive touch screen operation principle: 
 The 4wire resistive touch screen consists of a glass underlayer or film underlayer with a conductive coating and a cover layer with a conductive coating. The two layers are separated by tiny insulation points.
When touching a resistive touch screen, the controller separately drives the circuits on the bottom and overlay layers (X-axis and Y-axis)
The voltage is +5V and simulates the position of the touch from the change after the touch.
    

   75背面.jpg    Quality Assurance:
GreenTouch's 4wire resistive touch screens are made of well-known Chinese brands and are protected by FPC press-fits from different manufacturers. The result is a longer use of the GreenTouch 4wire resistive touch screen, life.  4wire resistive touch screen is highly sealed to IP65 standards, and each touch screen is tested for 3H pencil hardness by ASTM D3363. Already have ROHS, CE and FCC international agency certification.

   Product drawings:
7. 5 inch four-wire resistive touch screen display ratio of 16:9, touch screen structure is G + F. Dimensions: 172mmX109mm, viewing area: 165.4mmX100.4mm, drive area: 164mmX99mm. Display error is less than ±1%, 100,000 touch points per square inch,FPC flexible cable length 65mm, (Long side Outgoing line), the interface is a square socket with a double row 2x5, 2x6 needle, diameter 0.0635 mm.

   8包装.jpg    Product packaging:
The 7.5-inch four-wire resistive screen is divided into two types: inner and outer packaging. The inner layer is EPE foam and the outer layer is a traditional cardboard box. The touch screen is placed in the corresponding EPE grid, and each EPE grid is placed 5 to 10 pieces. Then place the EPE in the appropriate carton. Each size of the touch screen corresponds to each size of the package, and the figure is for reference only.

   Company Profile:
The GreenTouch factory is located in the high-tech city of Shenzhen, China. It covers an area of more than 2,000 square meters and has a plant area of more than 1,700 square meters. GreenTouch's resistive touch screen, projected capacitive touch screen, infrared touch screen, projected capacitive touch film, touch display and touch All-in-one, touch digital signage and open touch displays are developed and produced here.
