Important Safety Notice
1.

Safety precautions
This monitor is manufactured and tested on a ground principle that a user’s safety comes first.
However, improper used or installation may cause damage to the monitor as well as to the user.
Warning:
This monitor should be operated only at the correct power sources indicated on the label on the
rear of the monitor. If you’re unsure of the power supply in you residence, consult your local dealer
or Power Company.
Do not try to repair the monitor by yourself, as it contains no user-serviceable parts. This monitor
should only be repaired by a qualified technician.
Do not remove the monitor cabinet. There are high-voltage parts inside that may cause electric
shock to human bodies.
Stop using the monitor if the cabinet is damaged. Have it checked by a service technician.
Put your monitor only in a lean, cool, dry environment. If it gets wet, unplug the power cable
immediately and consult your closed dealer.
Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth. Apply
non-ammonia based cleaner onto the cloth, not directly onto the class screen.
Do not place heavy objects on the monitor or power cord.

Product safety notice
Many electrical and mechanical parts in this chassis have special safety visual inspections and the
protection afforded by them cannot necessarily be obtained by using replacement components rated
for higher voltage, wattage, etc. Before replacing any of these components read the parts list in this
manual carefully. The use of substitute replacement parts, which do not have the same safety
characteristics as specified in the parts list, may create shock, fire, or other hazards.

3.

Service notes
z

When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.

z

Keep wires away from high voltage, high temperature components and sharp edges.

z

Keep wires in their original position so as to reduce interference.

z

Adjustment of this product please refers to the user’ manual.

6. SOP of firmware upgrade

6.1 Operational

condition:

Equipment: PC, ISP card, signal cable and power cable.
ESD requirements:

antistatic wrists, antistatic gloves

(fingers), and connecting cable

Name of ISP program: RTDTool_4.6.exe
Manufacture of FW IC:RTD 2525L

6.2

Operational steps:
1. Connection: connect PC to PCBA with signal cable, and then keep AC and DC in open state.

One port of ISP
program card
is connected to
PC print port.
2. Adjust ISP programming
Firstly, double click ISP_Tool_v3.7.5EXEI and open ISP program, then select “Device”, next select
manufacturer model of FW IC, which should be correspondent with that of PCBA FW IC. Double click
Figure One.

Note 6

The waveform of the voltage output of inverter must be area-symmetric and the design of the
inverter must have specifications for the modularized lamp. The performance of the Backlight,
such as lifetime or brightness, is greatly influenced by the characteristics of the DC-AC inverter
for the lamp. All the parameters of an inverter should be carefully designed to avoid producing too
much current leakage from high voltage output of the inverter. When designing or ordering the
inverter please make sure that a poor lighting caused by the mismatch of the Backlight and the
inverter (miss-lighting, flicker, etc.) never occurs. If the above situation is confirmed, the module
should be operated in the same manners when it is installed in your instrument.

Note 1 :
The degree of unbalance: less than 10%
The ratio of wave height: less than 2 ± 10%

Ip

Ip: high side peak

I-p

I-p: low side peak

The degree of unbalance = |Ip-I-p| /Irms*100(%)
The ratio of wave height = Ip(or I-p)/Irms
Lamp should be completely turned on.

Note 2: Test equipment: AS-114B

Note 3: The voltage shown above should be applied to the lamp for more than 1 second after startup.
Otherwise, the lamp may not be turned on normally.

Note 4: Inverter should provide more than min. value, and then lamp could be completely turned on.
Note 5:Lamp frequency may produce interference with horizontal synchronous frequency and this
may cause line flow on the display. Therefore lamp frequency shall be detached from the
horizontal synchronous frequency and its harmonics as far as possible in order to avoid
interference.

Note 6:Lamp life definition: The brightness of lamp becomes 50% of the initial brightness or not
normal lighting.

1: Ambient temperature = 25°C.
2: To be measured in dark room after backlight warm up 30 minutes.
3: To be measured with a viewing cone of 2°by Topcon luminance meter BM-5A.
4: 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 the 10% and 90% of amplitudes.

E. Safety
1. Sharp Edge Requirements
There will be no sharp edges or corners on the display assembly that could cause injury.

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-V1
in the module will complete the flammability rating exception approval process. The printed circuit
board will be made from material rated 94-V1 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.

F. Display quality

The display quality of the color TFT-LCD module should be in compliance with the
Innolux’s Incoming inspection standard.

G. Handling precaution

The Handling of the TFT-LCD should be in compliance with the Innolux’s handling principle
standard.
