S P E C I F I C AT I O N S ClearTek 3000 Profile FLAT CAPACITIVE TOUCHSCREENS The Profile sensor, MicroTouch's innovative design for flat capacitive touchscreens, incorporates advanced design and production techniques that result in the highest quality capacitive touchscreen on the market. Profile's thin, sleek design provides ease-of-installation for LCD panels and flat panel displays. The narrow border and wide viewing area, combined with the unmatched durability, reliability, and optical clarity, make Profile the ideal choice for public access and business applications. Profile incorporates ClearTek(R) 3000's ultra-smooth overcoat, which dramatically increases physical durability by resisting scratches and abrasions to the touchscreen surface and sets new standards in environmental robustness. Profile Touchscreen Profile Sensor Construction Profile Sensor Construction Profile touchscreens are constructed of an all-glass flat sensor with a transparent, thin-film conductive coating applied to its top and bottom surfaces. A very narrow electrode pattern is printed along the edge on the conductive layer with a sealing glass applied over the pattern for protection. A transparent glass overcoat (ClearTek 3000) is fused over the conductive coating to protect and seal the sensor. The ClearTek 3000 coating features CleanScreen, which controls the growth of bacteria and other microorganisms on the surface of the touchscreen -- an antibacterial agent. The glass sensor can also be treated to provide the suitable clarity and anti-reflective properties for specific touchscreen applications. How ClearTek 3000 Works How ClearTek 3000 Works Voltage is applied to the screen (1) and the electrode pattern uniformly distributes a low-voltage field (2) over the conductive layer. When a finger touches the screen (3), it "capacitively couples" with the voltage field, drawing a minute amount of current to the point of contact. The current flow from each corner is proportional to the distance from the corner to the finger.The controller simply calculates the flow proportions to locate the x and y coordinate of the touch (4).

ClearTek 3000 is constructed of a glass layer and a glass overcoat. The glass overcoat resists scratches and can be configured with a polished or antiglare finish. The following tests measure the resistance of ClearTek 3000 to a variety of chemicals. Test Objective. The glass overcoat has been tested to resist the following chemicals. Test Goal. To document which chemicals are compatible with the glass overcoat. Test Methods. ASTMD-F-1598-95 and ASTMD1308-87 (1993) Test 1 ASTMD-F-1598-95 tests for chemical resistance effects of solvents and reagents. After a 10-minute spot test, no evidence of physical damage and all samples met the requirements of post chemical functional tests. 6% Hydrochloric Acid 70% Nitric Acid 40% Sulfuric Acid Acetone Brake Fluid 10% Sodium Hydroxide Toluene Xylene Windex Gasoline Test 2 ASTMD-F-1598-95 tests for chemical resistance effects of volatile liquids.
