SPECIFICATION
Liquid Crystal Display LC104S1-A1
5. 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.
6. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
T
S
is the time required for the brightness of the center of the lamp to be not less than 95%.
7. The lamp power consumption shown above does not include loss of external inverter.
The used lamp current is the lamp typical current.
8. 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.
9. 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.
