Note (3) The lamp frequency may produce interference with horizontal synchronization frequency from the
display, which might cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronization frequency and its harmonics as

Note (5) The lifetime of lamp can be defined as the time in which it continues to operate under the condition
Ta = 25 2 oC and IL = 7.0 mArms until one of the following events occurs:
(a) When the brightness becomes 50% of its original value.
(b) When the effective ignition length becomes 80% of its original value.
(The effective ignition length is a scope that luminance is over 80% of that at the center point.)
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.
The output of the inverter must have symmetrical (negative and positive) voltage waveform and
symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter

which has unsymmetrical voltage and unsymmetrical current and spike wave. Lamp frequency may
produce interface with horizontal synchronous frequency and as a result this may cause beat on the
display. Therefore lamp frequency shall be as away possible from the horizontal synchronous

frequency and from its harmonics in order to prevent interference.
Requirements for a system inverter design, which is intended to have a better display performance, a
better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its
leakage current.
a. The asymmetry rate of the inverter waveform should be 10% below;
b. The distortion rate of the waveform should be within 2 ± 10%;
c. The ideal sine wave form shall be symmetric in positive and negative polarities

Note.
(1) The supply voltage of the external system for the module input should be the same as the definition of Vcc.
(2) When the backlight turns on before the LCD operation of the LCD turns off, the display may momentarily
become abnormal screen.
(3) In case of Vcc = off level, please keep the level of input signals on the low or keep a high impedance.
(4) t4 should be measured after the module has been fully discharged between power of and on period.
(5) Interface signal shall not be kept at high impedance when the power is on.
(6) CMO won’t take any responsibility for the products which are damaged by the customers not following the
Power Sequence.
(7) There might be slight electronic noise when LCD is turned off (even backlight unit is also off). To avoid this
symptom, we suggest "Vcc falling timing" to follow "t7 spec".

11. PRECAUTIONS
11.1 ASSEMBLY AND HANDLING PRECAUTIONS
(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. This can
prevent damage to the CMOS LSI chips during latch-up.
(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.
(10) When ambient temperature is lower than 10ºC may reduce the display quality. For example, the
response time will become slowly, and the starting voltage of CCFL will be higher than room
temperature.

www.jxlcd.com
11.2 SAFETY PRECAUTIONS
(1) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while
assembling with inverter. Do not disassemble the module or insert anything into the Backlight unit.
(2) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In
case of contact with hands, skin or clothes, it has to be washed away thoroughly with soap.
(3) After the module’s end of life, it is not harmful in case of normal operation and storage.
11.3 SAFETY STANDARDS
The LCD module should be certified with safety regulations as follows:
(1) UL60950-1 or updated standard.
11.4. Storage
(2) IEC60950-1 or updated standard.
(1) Do not leave the module in high temperature, and high humidity for a long time.
It is highly recommended to store the module with temperature from 0 to 35
And relative humidity of less than 70%
(2) Do not store the TFT – LCD module in direct sunlight
(3) The module should be stored in dark place. It is prohibited to apply sunlight or fluorescent light in storing

11.5. Operation condition guide
(1) The LCD product should be operated under normal condition.
Normal condition is defined as below :
Temperature : 20±15
Humidity: 65±20%
Display pattern : continually changing pattern(Not stationary)
(2) If the product will be used in extreme conditions such as high temperature , high humidity , high altitude ,
display pattern or operation time etc…It is strongly recommended to contact CMO for application
engineering advice . Otherwise , Its reliability and function may not be guaranteed.
11.6 OTHER
When fixed patterns are displayed for a long time, remnant image is likely to occur.
