11. HANDLING PRECAUTIONS FOR TFT-LCD MODULE
Please pay attention to the followings in handling- TFT-LCD products;
11.1 ASSEMBLY PRECAUTION
11.2 OPERATING PRECAUTIONS
11.3 PRECAUTIONS WITH ELECTROSTATICS
CPT Confidential
(1) Please use the mounting hole on the module side in installing and do not beading or wrenching
(2) Please design display housing in accordance with the following guidelines.
(3) Please do not push or scratch LCD panel surface with any-thing hard. And do not soil LCD panel surface
(4) Please do not press any parts on the rear side such as source TCP, gate TCP, control circuit board and
(5) Please wipe out LCD panel surface with absorbent cotton or soft clothe in case of it being soiled.
(6) Please wipe out drops of adhesives like saliva and water on LCD panel surface immediately. They might
(7) Please do not take a LCD module to pieces and reconstruct it. Resolving and reconstructing modules may
(8) Please do not touch metal frames with bare hands and soiled gloves. A color change of the metal frames
(9) Please pay attention to handling lead wire of backlight so that it is not tugged in connecting with inverter.
(1) Please be sure to turn off the power supply before connecting and disconnecting signal input cable.
(2) Please do not change variable resistance settings in LCD module. They are adjusted to the most suitable
(3) Please consider that LCD backlight takes longer time to become stable of radiation characteristics in low
(4) A condensation might happen on the surface and inside of LCD module in case of sudden change of
(5) Please pay attention to displaying the same pattern for very long time. Image might stick on LCD. If then,
(6) Please obey the same caution descriptions as ones that need to pay attention to ordinary electronic parts.
(1) This LCD module use CMOS-IC on circuit board and TFT-LCD panel, and so it is easy to be affected by
