AZ DISPLAYS 11 ATM3224D SERIES TFT GRAPHIC MODULE VER1.0 12.0 PRECAUTION FOR USING LCM 1. When design the product with this LCD Module, make sure the viewing angle matches to its purpose of usage. 2. As LCD panel is made of glass substrate, Dropping the LCD module or banging it against hard objects may cause cracking or fragmentation. Especially at corners and edges. 3. Although the polarizer of this LCD Module has the anti-glare coating, always be careful not to scratch its surface. Use of a plastic cover is recommended to protect the surface of polarizer. 4. If the LCD module is stored at below specified temperature, the LC material may freeze and be deteriorated. If it is stored at above specified temperature, the molecular orientation of the LC material may change to Liquid state and it may not revert to its original state. Excessive temperature and humidity could cause polarizer peel off or bubble. Therefore, the LCD module should always be stored within specified temperature range. 5. Saliva or water droplets must be wiped off immediately as those may leave stains or cause color changes if remained for a long time. Water vapor will cause corrosion of ITO electrodes. 6. If the surface of LCD panel needs to be cleaned, wipe it swiftly with cotton or other soft cloth. If it is not still clean enough, blow a breath on the surface and wipe again. 7. The module should be driven according to the specified ratings to avoid malfunction and permanent damage. Applying DC voltage cause a rapid deterioration of LC material. Make sure to apply alternating waveform by continuous application of the M signal. Especially the power ON/OFF sequence should be kept to avoid latchup of driver LSIs and DC charge up to LCD panel. 8. Mechanical Considerations a) LCM are assembled and adjusted with a high degree of precision. Avoid excessive shocks and do not make any alterations or modifications. The following should be noted. b) Do not tamper in any way with the tabs on the metal frame. c) Do not modify the PCB by drilling extra holes, changing its outline, moving its components or modifying its pattern. d) Do not touch the elastomer connector; especially insert a backlight panel (for example, EL). e) When mounting a LCM makes sure that the PCB is not under any stress such as bending or twisting. Elastomer contacts are very delicate and missing pixels could result from slight dislocation of any of the elements. f) Avoid pressing on the metal bezel, otherwise the elastomer connector could be deformed and lose contact, resulting in missing pixels. 9. Static Electricity a) Operator Ware the electrostatics shielded clothes because human body may be statically charged if not ware shielded clothes. Never touch any of the conductive parts such as the LSI pads; the copper leads on the PCB and the interface terminals with any parts of the human body. b) Equipment There is a possibility that the static electricity is charged to the equipment, which has a function of peeling or friction action (ex: conveyer, soldering iron, working table). Earth the equipment through proper resistance (electrostatic earth: 1x108 ohm). Only properly grounded soldering irons should be used. If an electric screwdriver is used, it should be well grounded and shielded from commutator sparks. The normal static prevention measures should be observed for work clothes and working benches; for the latter conductive (rubber) mat is recommended. c) Floor Floor is the important part to drain static electricity, which is generated by operators or equipment. There is a possibility that charged static electricity is not properly drained in case of insulating floor. Set the electrostatic earth (electrostatic earth: 1x108 ohm). d) Humidity Proper humidity helps in reducing the chance of generating electrostatic charges. Humidity should be kept betweens 45%RH ~60%RH. e) Transportation/storage The storage materials also need to be anti-static treated because there is a possibility that the human body or storage materials such as containers may be statically charged by friction or peeling. The modules should be kept in antistatic bags or other containers resistant to static for storage. f) Soldering Solder only to the I/O terminals. Use only soldering irons with proper grounding and no leakage. Soldering temperature : 280°C ± 10°C Soldering time: 3 to 4 sec. AZ DISPLAYS 12 ATM3224D SERIES TFT GRAPHIC MODULE VER1.0 Use eutectic solder with resin flux fill. If flux is used, the LCD surface should be covered to avoid flux spatters. Flux residue should be removed afterwards. g) Others 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 during operation (such as pressing on the viewing area) may cause the segments 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. Avoid the exposure of the module to the direct sunlight or strong ultraviolet light for a long time. 16.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 brightness.
