4.1
Resetting the LCD module
The LCD module should be initialized by using /RST terminal.
While turning on the VDD and VSS power supply, maintain /RST terminal at LOW level. After the
power supply stabilized, release the reset terminal (/RST=HIGH)

Design and Handling Precaution
1.
The LCD panel is made by glass. Any mechanical shock (eg. dropping form high place)
will damage the LCD module.
2.
Do not add excessive force on the surface of the display, which may cause the Display
color change abnormally.
3.
The polarizer on the LCD is easily get scratched. If possible, do not remove the LCD
protective film until the last step of installation.
4.
Never attempt to disassemble or rework the LCD module.
5.
Only Clean the LCD with Isopropyl Alcohol or Ethyl Alcohol. Other solvents (eg. water)
may damage the LCD.
6.
When mounting the LCD module, make sure that it is free form twisting, warping and
distortion.
7.
Ensure to provide enough space (with cushion) between case and LCD panel to prevent
external force adding on it, or it may cause damage to the LCD or degrade the display
result.
8.
Only hold the LCD module by its side. Never hold LCD module by add force on the heat
seal or TAB.
9.
Never add force to component of the LCD module. It may cause invisible damage or
degrade of the reliability.
10.
LCD module could be easily damaged by static electricity. Be careful to maintain an
optimum anti-static work environment to protect the LCD module.
11.
When peeling off the protective film from LCD, static charge may cause abnormal
display pattern. It is normal and will resume to normal in a short while.
12.
Take care and prevent get hurt by the LCD panel sharp edge.
13.
Never operate the LCD module exceed the absolute maximum ratings.
14.
Keep the signal line as short as possible to prevent noisy signal applying to LCD module.
15.
Never apply signal to the LCD module without power supply.
16.
IC chip (eg. TAB or COG) is sensitive to the light. Strong lighting environment could
possibly cause malfunction. Light sealing structure casing is recommend.
17.
LCD module reliability may be reduced by temperature shock.
18.
When storing the LCD module, avoid exposure to the direct sunlight, high humidity, high
temperature or low temperature. They may damage or degrade the LCD module
