5. Safety
5-1. Sharp edge requirements
There will be no sharp edges or corners on the display assembly that could cause injury.
5-2. Materials
a. Toxicity
There will be no carcinogenic materials used anywhere in the display module. If toxic materials
are used, they will be reviewed and approved by the responsible InnoLux Toxicologist.
b. Flammability
All components including electrical components that do not meet the flammability grade UL94-V0
in the module will complete the flammability rating exception approval process. The printed circuit
board will be made from material rated 94-V0 or better. The actual UL flammability rating will be
printed on the printed circuit board.
c. Capacitors
If any polarized capacitors are used in the display assembly, provisions will be made to keep
them from being inserted backwards.
6. Display quality
The display quality of the color TFT-LCD module should be in compliance with the InnoLux
incoming inspection standard.
www.jxlcd.com
www.jxlcd.com
7. Handling precaution
(1) Do not apply rough force such as bending or twisting to the module during assembly.
(2) To assemble or install module into user’s system can be only in clean working areas. The
dust and oil may cause electrical short or worsen the polarizer.
(3) It’s not permitted to have pressure or impulse on the module because the LCD panel and
backlight will be damaged.
(4) Always follow the correct power sequence when LCD module is connecting and
operating.
(5) Do not pull the I/F connector in or out while the module is operating.
(6) Do not disassemble the module.
(7) Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is
very soft and easily scratched.
(8) It is dangerous that moisture come into or contacted the LCD module, because moisture
may damage LCD module when it is operating.
(9) High temperature or humidity may reduce the performance of module. Please store LCD
module within the specified storage conditions.
