THE ENVIRONMENTAL CONDITION OF INSPECTION
The environmental condition and visual inspection shall be conducted as below.
(1) Ambient temperature : 25+/-5C(2) Humidity : 25-75 % RH
(3) Panel visual inspection on the operation condition for cosmetic shall be conducted at the distance
30~40cm or more between the LCD module and eyes of inspector.
Ambient Illumination : 800~1200 Lux for external appearance inspection
Ambient Illumination : 200~500 Lux for light on inspection(4) The viewing angel:a) +/-15 degree to the front surface of display panel in vertical direction.
b) +/-15 degree to the front surface of display panel in horizontal direction.

INSPECTION CRITERIA(1) Definition of dot defect induced from the panel insidea) Bright dot: Dots appear bright and unchanged in size in which LCD panel is displaying
under black pattern.
b) Dark dot: Dots appear dark and unchanged in size in which LCD panel is displaying underpure red, green, blue picture.
c) 2 dot adjacent = 1 pair = 2dots

HANDLING PRECAUTIONS(1) CAUTION OF LCD HANDLING- The LCD panel is plate glass. Do not subject the panel to mechanical shock or to excessive force on
its surface.
- The polarizer attached to the display is easily damaged. Please handle it carefully to avoid scratch
or other damages.
- To avoid contamination on the display surface, do not touch the module surface with bare hands.
- Keep a space so that the LCD panels do not touch other components.
- Put cover board such as acrylic board on the surface of LCD panel to protect panel from damages.
- Transparent electrodes may be disconnected if you use the LCD panel under environmental
conditions where the condensation of dew occurs.
- Do not leave module in direct sunlight to avoid malfunction of the ICs.
(2) CAUTION OF LCD CLEANING- Do not wipe the polarizer with dry cloth. It might cause scratch.
- Only use a soft cloth with IPA to wipe the polarizer, other chemicals might permanent damage tothe polarizer.
(3) CAUTION OF STORAGE- Store the module in a dark room where must keep at 25+/-10C and 65%RH or less.
- Do not store the module in surroundings containing organic solvent or corrosive gas.
- Store the module in an anti-electrostatic container or bag.
(4) STATIC ELECTRICITY- Be sure to ground module before turning on power or operating module.
- Do not apply voltage which exceeds the absolute maximum rating value.
(5) TRANSPORTATION PRECAUTIONSThe LCD modules should be no falling and violent shocking during transportation, and also should
avoid excessive press, water, damp and sunshine.
(6) SAFETY- For crash damage or unnecessary LCD’s, it is recommended to wash off liquid crystal by either ofsolvents such as acetone and ethanol and should be burned up later.
- When any liquid leaked out of a damage glass cell comes in contact with your hands, wash it off
with soap and water.
