1. The specified current and power consumption are under the V

°C, f

Typical supply current is measured at the condition of 8 X 6 chess pattern(white & black)

2. This impedance value is for impedance matching between LVDS T

the mating connector of the LCD.

3. The duration of rush current is about 1ms.

4. The variance of the voltage is

± 10%.

5. The voltage above V

Otherwise, the lamps may not be turned on.

6. The output of the inverter must have symmetrical (negat ive 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.

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

T

The used lamp current is the lamp typical current.

8. The lamp power consumption shown above does not includeloss of external inverter.

The used lamp current is the lamp typical current.

9. The life time 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.

Typical life time shall be defined that remained rate maintains over 50% of total amount at the life test.

? Do not attach a conductive 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.
