SPECIAL NOTICE TO CUSTOMER USING THE PRODUCTS
AND TECHNICAL INFORMATION SHOWN IN THIS BROCHURE
13-1.Handling
(1) Since the LCD panel is made of glass, avoid applying excessive shocks to the module by dropping, bending or twisting.
(2) Do not touch, press or rub the display panel with a hard tool or object such as tweezers because the polarizers in the panel are easily scratched.
(3) Do not use organic solvents to clean the display panel off as these solvent may be adverse to polarizers.
To clean the surface off, dried cloth, dampened absorbent cotton with petroleum benzine or adhesive tape are preferable.
(4) Wipe off water drops immediately ; contact with water over a long period of time may cause deformation or color fading.
(5) Avoid using or storing the module under the conditions where high temperatures and high humidity may exist.
When stored, this module should be packaged in a conductive polyethylene bag and placed under relatively low temperatures(5~30
C). Direct sunlight or light from fluorescent
lamp should be avoided during the storage.
(6) The liquid crystal inside of the panel is harmful ; if any liquid leads out and comes in contact with skin or clothes, wash off immediately with soap and water. Never put that in the
mouth.
(7) The LCD module has a TCP (Tape Carrier Package) structure. Please do not bend or modify during the mounting process.
(8) This module is designed for the equipment to be used in an air-conditioned room without any vibration and mechanical shock. Avoid using it under other conditions.
13-2.Operation
(1) Never connect or disconnect the module from the main system while power is being supplied.
(2) Please be advised that the LCD module may not function correctly if the storage temperature exceeds the range of the specification.
(3) Optical characteristics (viewing angle and contrast ratio) vary according to the driving voltage(VEE) of liquid crystal.
Adjust(VEE) so that the LCD has the optimum cotrast.
(4) Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit.
Therefore, it must be used under the relative condition of 40
C 85%RH.
Care should be taken for rapid temperature change because it may cause the condensation.
(5) Do not touch any connector terminal, mounted component or PCB during operation.
If touched, injury to the operator may occur due to applied high voltage. Damage to the display is also possible.
(6) This module is designed to operate under 1/240 duty. Using other duty ratios may cause certain problems.
(7) Power supply sequence
Please be aware that the LSI that is used inside the LCD module may be damaged due to the "Floating phenomenon" or "Latch-up phenomenon" when the LCD supply voltage
(VEE) and / or other signals are input before the power supply for logic (VDD) gets stable.
13-3.Installation
(1) Do not disassemble or modify the module. In case of disassembling or modification, if the module dose not work due to the result of such action, Stanley will not be responsible
for the failure.
(2) Care should be taken regarding ESD, as the circuit of the module contains CMOS LSI(s).
The assemblers body should be grounded with an earthband . Material which prevents static electricity should be selected for a clothing.
(3) The module is mounted by using the holes on the 4 corners of it. In order to secure it on a flat surface, care should be taken not to apply excessive stress to cause "warp" or
"distortion".
If applied on the LCD panel, that may cause color change or damage.
(4) Cover with display a transparent acrylic panel to protect the polarizer and the LCD panel.
Make a space between the protective panel and the module to prevent stress.
(5) Dusting the module may affect the display adversely; Care should be taken when used in a dusty environment.
(6) The metal case is not included in the inspection criteria. Due to this reason, it is recommended to generate a design that the metal frame is invisible.
(7) It will be hot around CFL. Please give an attention to the heat radiation and LCD panel should be used within environmental condition specified in 2-1.
