Note (2) The voltage that must be larger than Vs should be applied to the lamp for more than 1 second

NF circuit.

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

far as possible.

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.

better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its

leakage current.

Note.

(1) The supply voltage of the external system for the module input should be the same as the definition of Vcc.

(2) Apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD

operation of the LCD turns off before the backlight 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 off 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.

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.

24 / 27

Version 2.0

One step solution for LCD / PDP / OLED panel application: Datasheet, inventory and accessory!

www.panelook.com

Global LCD Panel Exchange Center

(3) After the module’s end of life, it is not harmful in case of normal operation and storage.

www.panelook.com

11.3 SAFETY STANDARDS

The LCD module should be certified with safety regulations as follows:

(1) UL60950-1 or updated standard.

(2) IEC60950-1 or updated standard.

11.4. Storage

(1) Do not leave the module in high temperature, and high humidity for a long time.

Issued Date: 29. Apr., 2010

Model No.: V270H1-L01

Approval

It is highly recommended to store the module with temperature from 0

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

к

to 35к

11.5. Operation condition guide

(1) The LCD product should be operated under normal condition.

Normal condition is defined as below :

к

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.
