• Manufacturer Part Number: LM190E05-SL02
• Description: LCD Module
• Manufacturer: LG

Notes :
Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.
LAMP for each CCFL:
Operating Current
The design of the inverter must have specifications for the lamp in LCD Assembly.
The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced
by the characteristics of the DC-AC inverter. So all the parameters of an inverter should be carefully
designed so as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of
the lamp and the inverter (no lighting, flicker, etc) never occurs. When you confirm it, the LCD–Assembly
should be operated in the same condition as installed in you instrument.
TFT-LCD Module has a low luminance and the inverter has abnormal action.
Because leakage current is occurred between lamp wire and conducting tape.
1. Specified values are for a single lamp.
2. Operating voltage is measured at 25 ± 2 C. The variance of the voltage is ± 10%.
3. The voltage above V
Ver 0.0
4. Lamp frequency may produce interface with horizontal synchronous frequency and as a result
5. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
6. The lamp power consumption shown above does not include loss of external inverter.
7. The life is determined as the time at which brightness of the lamp is 50% compared to that

Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to a conducting tape,

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.
T
The used lamp current is the lamp typical current. (P
(Inverter open voltage must be more than lamp starting voltage.)
S
is the time required for the brightness of the center of the lamp to be not less than 95%.
