4 1. Operating Precautions 01) Since front polarizer is easily damaged, please be cautious and not to scratch it. 02) Be sure to turn off power supply when inserting or disconnecting from input connector. 03) Wipe off water drop immediately. Long contact with water may cause discoloration or spots. 04) When the panel surface is soiled, wipe it with absorbent cotton or soft cloth. 05) Since the panel is made of glass, it may be broken or cracked if dropped or bumped on hard 05) surface. 06) To avoid ESD (Electro Static Discharde) damage, be sure to ground yourself before handling 06) TFT-LCD Module. 07) Do not open nor modify the module assembly. 08) Do not press the reflector sheet at the back of the module to any direction. 09) In case if a module has to be put back into the packing container slot after it was taken out from 09) the container, do not press the center of the LED Reflector edge. Instead, press at the far ends of 09) the LED Reflector edge softly. Otherwise the TFT Module may be damaged. 10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the 10) Interface Connector of the TFT Module. 11) Please pay attention for the matter as stated below at mounting design of the TFT module with 11) Touch Sensor & enclosure: 11) After installation of the TFT Module with Touch Sensor into an enclosure 11) (Notebook PC Bezel, for example), do not twist nor bend the TFT Module with Touch Sensor 11) even momentary. At designing the enclosure, it should betaken into consideration that 11) no bending/twisting forces are applied to the TFT Module with Touch Sensor from outside. 11) Otherwise the TFT Module with Touch Sensor may be damaged. 11) Enclosure support to fix TFT Module with Touch Sensor must be out of view (transparent) 11) area.(do not design enclosure presses the view area to protect from miss input) 11) Enclosure edge must be between view area & Guaranteed active area. 11) (Enclosure edge must not touch with view area) 11) We recommend the material of support to fix touch sensor is elastic material. 11) Do not bond top surface (film) of touch sensor with enclosure. 11) The corner parts have conductivity. Do not touch any metal part after mounting. 11) Special design is required for water resistance use. 11) Cleaning Touch panel by Air gun, pressure 2kg/cm2 below is suggested. This is preventing FPC 11) to peel off when air is blowing to FPC from glass side. 11) The mounting structure must has a reserved space for the FPC tail and never touch or squeeze 11) the FPC by case or another components preventing FPC to peel off. 12) Small amount of materials having no flammability grade is used in the LCD module. The LCD 12) module should be supplied by power complied with requirements of Limited Power Source 12) (IEC60950 or UL1950), or be applied exemption. 13) Severe temperature condition may result in different luminance, response time. 14) Continuous operating TFT-LCD display under high temperature environment may accelerate 14) LED light bar exhaustion and reduce luminance dramatically. 15) The data on this specification sheet is applicable when LCD module is placed in landscape 15) position. 16) Continuous displaying fixed pattern may induce image sticking. It is recommended to use 16) screen saver or shuffle content periodically if fixed pattern is displayed on the screen. 17) Do not lift Touch Panel by cable(fpc). 4/30

27 11-3 Handling Notes Precautions This product is intended for use in standard applic ations (computers, office automation, and other office equipment, industrial, communications, and measurement equipment, personal and household devices, etc.) Please avoid using this product for special applications where failure or abnormal operation may directly affect human lives, or cause physical injury or property damage, or where extremely high levels of reliability are required (such as aerospace systems, vehicle operating control, atomic energy controls, medical devices for life support, etc.). Handling Notes Do not press or scratch the product with any object with a sharp edge or end. Do not forcibly bend or fold the product. When the product is stored, make sure it is packed in a packing box and stored in a storage temperature range, eliminating any outside load. Do not use or store the product under a condition where the product will be exposed to water, organic solution or acid. Do not use the product under the direct sunlight if a film material is used on it. Do not disassemble the product. When you handle the product, hold the product by its body. Do not hold by the tail. Clean the product with a soft cloth or a soft cloth with neutral detergent or alcohol. When contaminated with chemicals, wipe them off immediately with caution not to cause injury to human body. The edge of the glass is not rounded and may cause injury. Construction Notes The environmental specifications, mechanical characteristics, and electrical characteristics are only applied to the Active Area. Do not use the touchscreen when the condensationoccurs. The condensation inside of the touchscreen is a natural phenomenon and should disappear after the touchscreen is warmed up. Electrical & Software Notice Projected Capacitive Touchscreen was designed to work with our controller board. If the driver software is to be developed by the customer, please study the characteristics of touch screen and controller before development. Mounting Notes Projected capacitive touchscreen detects the touched locations by measuring the increased amount of the capacitance value between its electrodes at inputs. Once it is built into a system, capacitance couplings are continually yielded among the touchscreen, FPC tail, controller board and metal Chassis. When turned on, our projected capacitive touchscreen will automatically adjust its sensitivity level to the surrounding environment at the standby state in order to avoid the affects by the surrounding capacitance couplings. If surrounding environment changes or materials to alter the electrical field (a large capacitor, power-supply unit, LCD panel, or materials with high dielectric constant) is near, these external factors will adversely affect the function of the touch screen to detect the correct input positions. At structure design, please refer to the mounting notes below and ensure enough gap distances among each component in order to avoid the external factors described above. 27/30

Mounting Fix the touchscreen firmly so that the gap distances between the touchscreen and other components will not be affected by touching or will not change with the passage of time.

Between LCD panel and touchscreen: L1 Between touchscreen and the surface of the bezel: L4 Between touchscreen and the back of the bezel: L2 Between tail and LCD panel, tail and metal chassis : L3 &

28 Mounting Fix the touchscreen firmly so that the gap distances between the touchscreen and other components will not be affected by touching or will not change with the passage of time. An unexpected input may be caused if the gap is too narrow. The locations on which a certain gap distance is required are as follows. Between LCD panel and touchscreen: L1 Between touchscreen and the surface of the bezel: L4 Between touchscreen and the back of the bezel: L2 Between tail and LCD panel, tail and metal chassis : L3 & L5 (an insulating tape can be used) In case of using capacitive sensor outside, the moisture may cause the trouble. Mouting Toutchscreen on a display It is recommended to use an insulating resin material for the bezel. Ensure the gap between the touchscreen and front bezel (L4) If a metal plate is used for the bezel, unintended capacitance couplings may occur on the periphery of the active area. If a metal material is used for bezel, ensure the gap of approximately 2mm between touchscreen and bezel (L2). In order to avoid the gap distance L1 from being changed with the passage of time, it is recommended to apply the adhesive tape onto all the 4 sides with no space (fully sealed) when gluing the touch screen. Tolerance There is a tolerance of 0.2 to 0.3mm for the dimensions of the touchscreen and tail. A gap must be made in the case and the connector to absorb the tolerance. Fig Tail The tail must not be forcibly stressed or bent too hard. The conduction in the insulated area and wire breaking may be caused Fig /30
