e. Backlight unit
The backlight system is an edge-lighting type with a CCFT(Cold Cathode Fluorescent Tube).
The characteristics of a single lamp are shown in the following tables.

Note 2: Inverter should be designed with the characteristic of lamp. When you are designing
the inverter, the output voltage of the inverter should comply with the following
conditions.
(1). The area under the positive and negative cycles of the waveform of the lamp
current and lamp voltage should be area symmetric(the symmetric ratio should be
larger than 90%).
(2). There should not have any spikes in the waveform.
(3). The waveform should be sine wave as possible.
(4). Lamp current should not exceed the maximum value within the operating
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.
Note 3: The inverter open voltage should be designed larger than the lamp starting voltage at
T=0oC, otherwise backlight may be blinking for a moment after turning on or not be
able to turn on. The open voltage should be measured after ballast capacitor. If an
inverter has shutdown function it should keep its open voltage for longer than 1
second even if lamp connector is open.
Note 4: Lamp frequency may produce interference with horizontal synchronous frequency and
this may cause line flow on the display. Therefore lamp frequency shall be detached
from the horizontal synchronous frequency and its harmonics as far as possible in
order to avoid interference. In case using the inverter by PWM control, PWM
frequency may interference with frame frequency. We suggest that PWM frequency
is same as frame frequency.
Note 5: Brightness to be decrease to the 50% of the initial value under IL = 6mA.
Note 6: CN2 connector (backlight): BHSR-02VS-1(JST).
Mating connector: SM02B-BHSS-1-TB (JST).
