18 6 Touch Panel 6.1 Mechanical Characteristics Items Value Operation Force 10~100g Operation Life Tapping Durability 1,000,000 times Pen sliding Durability 100,000 times Surface Hardness 3H Linearity 1.5% Operation force is defined as the minimum force it makes the contact resistance stable when tapped with a 0.8mm radius rigid tip. 6.2 Structure And Area Definition The structure and the performance guaranteed areas of this touch panel are defined below: Fig. 1 Area A: Active area The area guarantees a touch panel operation with the following characteristics when pressed, (1)Operation force, (2) Electric characteristics, (3) Tapping durability, (4) Pen sliding durability, Area B: Operation non-guaranteed area The area does not guarantee a touch panel operation and its function. When this area is pressed, touch panel shows degradation of its performance and durability such as a pen sliding durability becomes about one-tenth compared with the active area (Area A) and its operation force requires about double. About 0.5mm outside from the boundary of the active area corresponds to this area. Area C: Pressing prohibition area The area forbids pressing because an excessive load is applied to the transparent electrode and a serious damage will be given to the touch panel function. About 0.5mm outside from the boundary of Area B corresponds to this area. Area D: Non-Active area (Frame) This area does not activate even if pressed. Area B and Area C: Sensitive area Area B and Area C both belong to the sensitive area. This area has a clearance between top and bottom contact side. Great press resulting in transparent electrode cracks, function defect to be exact, will deform surface transparent electrode. Please think about structure of sensitive area and case in order to avoid terminal user to fail to touch this area. Tel: FAX: Page 16 of 21

21 6.4. PRECAUTIONS FOR USE Precautions for operation A. Operate it with a polyacetal pen (tip R=2mm or over) or a belly of a finger without applying excessive load. B. Do not operate by other than polyacetal pen(tip R=2mm or over) and/or a belly of a finger like a hard or a sharp edges such as a ball point pen, sharp pencil., sharp tiptoe, etc. C. The input position may be fluctuated a little through long-time use. It is desirable to provide a zero-adjustment function by using a circuit and software. D. Use ethanol to remove stain from the product surface. If ethanol soaks into the joint of upper film and bottom glass, it may cause peeling and defective operation. E. Do not use alkaline detergents including glass cleaner, manicure remover (toluene), benzene or other organic solvents Precautions for storage A. Store the products at the temperature and humidity mentioned in the specification in a state of package with carefully. Do not expose the products in the direct sunlight. B. Avoid stacking touch panels together in a heap. Avoid pressure on touch panel surface for long time. Otherwise, it may cause the product to be scratched and/or defective operation. Tel: FAX: Page 19 of 21

22 6.4.3 Precautions for handling A. Finger sacks, gloves and mask to protect the products from fingerprint of stain, and also hold the portions outside the view area when handling. B. Using finger coat or gloves to avoid injury by possibly sharp edges when handling the products. C. Do not put a heavy, hard or sharp object on the touch panel. D. Do not handle the product by holding the flexible pattern portion in order to assure the reliability. E. Do not put one product on the other. Otherwise, it may cause the product to be scratched Other cautions A. Please note that dew gathering in the panel due to abrupt temperature or humidity change will cause deterioration of the performance. Tel: FAX: Page 20 of 21
