18.5inch Capacitive Touch Screen

Technology Capacitive touch screen > Can withstand more than 50000000 point > 4096x4096 Resolution > USB Interface > High accuracy and sensitivity > Glass + Film or Glass + Glass or PET + Glass  > Finger, gloved hand and touch pen activation > Sensitive and fast response > Our products have passed CE, FCC, ROHS certification!   Capacitive touch screen technology description Capacitive touch screen is a four-storey glass screen surface and laminated within the glass screen is coated with a layer of ITO, the outermost layer is a thin layer of silica glass, laminated ITO coating as a face, four electrode leads in the four corners, inner ITO good shielding to ensure a good working environment.     When finger touch the metal layer that is, because the body farm, users and touch-screen surface with a coupling capacitor, high frequency current, capacitance is a direct conductor, so fingers sucked away a very small amount of current from the contact point. The respectively current outflow from the touch electrode on the four corners of the screen, and flows through the four electrode current is proportional to the distance from the fingers to the four corners, controller through the accurate calculation of the four current percentage, came to the location of the touch point.   Product Specification  Interface Type:  USB  Resolution  4096x4096  Screen Ratio 16:9  Material  Glass + Glass  Certificates  CE, FCC, RoHS  Input method  Finger or touch pen  Position accuracy  2~5mm  Operating Voltage  3.3V adjustable  Operating current  2.5~10mA Depends on IC  Response time  Less than 10ms  Touch action force  30~60g  Operating temperature  -10°C~60°C  Storage temperature  -20°C~80°C  Surface hardness  ≥7H  Working environment  Under sunlight, indoor and outdoor  Transparency  ≥92%  Isolation resistance  ≥20MΩ DC 25V  The number of hits  ≥50000000/point  Warranty  1 year   Support Systems  Windows XP/Win 7/ Win 8/Win 10/Linux/Android Product image: Packaging   FAQ Q1: Are you a manufacturer or trading company?
