Electrical Specification
The backlight system is an edge-lighting type with a CCFL (Cold Cathode Fluorescent Lamp).
The characteristics of a single lamp are shown in the following tables.
Note 1: T= 25℃
Note 2: Inverter should be designed with the characteristic of lamp. When you are designing the
Note 3: The inverter open voltage should be designed larger than the lamp starting voltage at
Note 4: Lamp frequency may produce interference with horizontal synchronous frequency and

has shutdown function it should keep its open voltage for longer than 1 second even if

this may cause line flow on the display.

(3). The waveform should be sine wave as possible.
(4). Lamp current should not exceed the maximum value within the operating

larger than 90%).
temperature (It is prohibited to over the maximum lamp current even if operated in
the non-guaranteed temperature). When lamp current over the maximum value for
a long time, it may cause fire. Therefore, it is recommend that the inverter should
have the current limited circuit.
