(1) handling of the product take hold of both ends without touch the fpc when customer pulls out products (lcd modules) from the tray. take the measures of electrostatic discharge such as earth band, ionic shower and so on, when customer deals with the product, because products may be damaged by electrostatic. since the lcd panel is made from fragile glass materials, impulse and pressure to the product must be avoided. as the surface of touch panel is easily scratched, use a soft dry cloth without chemicals for cleaning. do not push-pull fpc while the product is working, because wrong power sequence may break down the product. put the product rear side down on a flat horizontal plane. handle the fpc with care. when the product is operating, do not loose the logic signals. if any one or more of these signals were lost, the product would be damaged. flexing or adding pressure to the product will result in a non-uniformity image. when the product is mounted to customer chassis, evaluate the display condition carefully. do not fold the fpc. when folding the fpc, pattern disconnection may be caused. in case of bending fpc, the minimum curvature (r) must be more than 1.0 mm. (2) environment do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. keep the product on the tray in antistatic pouch in room temperature, because of avoidance for dusts and sunlight, if customer stores the product. in order to prevent dew condensation occurring by temperature difference, the product packing box must be opened after leave under the environment of an unpacking room temperature enough. because a situation of dew condensation occurring is changed by the environmental temperature and humidity, evaluate the leaving time sufficiently. (recommendation leaving time: 6 hour or more with packing state) do not operate in high magnetic field. circuit boards may be broken down by it. this product is not designed as radiation hardened. (3) characteristics response time, luminance and color may be changed by ambient temperature. do not display the fixed pattern for a long time because it may cause image sticking. the lcd may be seemed luminance non-uniformity, flicker, vertical seam or small spot by display patterns. optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change depending on operating time, because the product has led backlight. (4) other do not disassemble and/or reassemble the product. pack the product with original shipping package, because of avoidance of some damages during transportation, when customer returns it to nec for replacement and so on.
