21.5" 4-Wire Resistive Screen,Zero-Bezel

       21.5" 4-wire resistive touch screen
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.    

       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:
The 21.5-inch four-wire resistive touch screen has a 16:9 aspect ratio and the touch screen structure is G+F. Dimensions: 490mmX285mm, viewing area: 480mmX270mm, drive area: 476mmX266mm. The display error is less than ±1%, 100000 touch points per square inch, FPC flexible cable length is 90mm, (The longitudinal line (Long side Outgoing line),), the interface is square socket with double row 2x5, 2x6 needle, diameter is 0.0635 mm.    

       Product packaging:
The 21.5-inch four-wire resistive screen is divided into two inner and outer packages, with an EPE foam inner layer and a traditional cardboard outer layer. Place the touch screen into the corresponding EPE foam, each touch screen corresponding to each EPE grid. There are 10 grids, each grid can put 1~2 pieces. Then put the EPE into the corresponding carton. Each size of the touch screen corresponds to each size of the package. This 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.
