    5-Wire Touch Screen Our new 5-wire touch screens provide high clarity,
    exceptional durability and reliability. The 5-wire touch screens are offered in four
    sizes 10.4",12.1,15"and 17”and provide the ideal solution for repetitive
    applications such as point-of-sale and restaurant systems.

    8-Wire Touch Screen Our 8-wire touch screen is the standard for rugged
    environments where the touch screen unit is larger than 10.4 inches. The
    advantage of the 8-wire touch screen is its ability to withstand extreme heat,
    humidity, airborne contaminants;
    it is also immune to voltage and resistance fluctuation. The 8-wire design is   
    recommended for factory machinery, industrial applications, voting machines,
    KIOSK and other larger size electronic applications.

     Surface Finish: 
    In order to provide the best match for any application's environment, we offer a 
   choice of surface finishes for all their touch screen components.
   1) Antiglare: Antiglare finish is desirable in environments where glare from ambient
       lighting may interfere with viewability, and/or the likelihood of frequent   
       scratching is high. The antiglare finish provides higher clarity and is well suited
       to drag-and-drop operations. High antiglare index provides the strongest    
       resistance to environmental reflection, and is well suited to outdoor settings.

   2)Clear: Where ambient glare is not likely to be a problem, our clear finish provides 
      the best possible image quality and best visual results.

   3)Hardness: Our touch screens carry a surface hardness index greater than 3H
      (pencil hardness).

   Tail termination type: 
   1)Integral: 
　 a. Extends circuitry wires to form tail
    b. Can not separate from circuitry layer
　 c. Sturdy construction

   2)FPC (Flexible Printed Circuit):
　 a. Narrower allowable bend radius
　 b. Accepts many more repeated connections

   3)HSC (Heat Sealed)
　 a. Narrowest bend radius available
　 b. Maximum flexibility
　 c. Lowest cost
