Table 2_2. ELECTRICAL CHARACTERISTICS

Note : 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.

?

Do not attach a conducting tape to lamp connecting wire.

If the lamp wire attach to a conducting tape, 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

(Inverter open voltage must be more than lamp starting voltage.)

Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.

4. 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.

5. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.

T

6. The lamp power consumption shown above does not include loss of external inverter.

The used lamp current is the lamp typical current. (P

7. The life is determined as the time at which brightness of the lamp is 50% compared to that of initial

value at the typical lamp current on condition of continuous operating at 25

± 2°C.
