ATM0700D8A-CT( az dis plays tft module v1.0 az displays 17 the laminator (protective film) is attached on the surface of lcd panel to prevent it from scratches or stains. it should be peeled off slowly using static eliminator. static eliminator should also be installed to the workbench to prevent lcd module from static charge. 10. operation a) driving voltage should be kept within specified range; excess voltage shortens display life. b ) response time increases with decrease in temperature. c) display may turn black or dark blue at temperatures above its operational range; this is (however not pressing on the viewing area) may cause the segments to appear ?fractured?. d ) mechanical disturbance durin g operation ( such as pressin g on the viewin g area ) ma y cause the se g ments to appear ?fractured?. 11. if any fluid leaks out of a damaged glass cell, wash off any human part that comes into contact with soap and water. the toxicity is extremely low but caution should be exercised at all the time. 12. disassembling the lcd module can cause permanent damage and it should be strictly avoided. 13. lcd retains the display pattern when it is applied for long time (image retention). to prevent image retention, do not apply the fixed pattern for a long time. image retention is not a deterioration of lcd. it will be removed after display pattern is changed. 14. do not use any materials, which emit gas from epoxy resin (hardener for amine) and silicone adhesive agent (dealcohol or deoxym) to prevent discoloration of polarizer due to gas. 15. a void the exposure of the module to the direct sunlight or strong ultraviolet light for a long time. the brightness of lcd module may be affected by the routing of ccfl cables due to leakage to the chassis through coupling effect. the inverter circuit needs to be designed taking the level of leakage current into consideration. thorough evaluation is needed for lcd module and inverter built into its host equipment to ensure specified brig htness.
