atm0177b3a(az displays)tft module ver1.0 az displays 13 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. disassemblin g the lcd module can cause permanent dama g e and it should be strictl y 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 sunli g ht or stron g ultraviolet li g ht for a lon g time.
