Note 3: Definition of response time:
The output signals of BM-7 are measured when the input signals are changed from “Black” to
“White” (falling time) and from “White” to “Black” (rising time), respectively. The response time
interval is between 10% and 90% of amplitudes. Refer to figure as below.

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.
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.
