Note (2) The voltage that must be larger than Vs should be applied to the lamp for more than 1 second
after startup. Otherwise, the lamp may not be turned on normally. It is the value output voltage of
NF circuit.
Note (3) The lamp frequency may produce interference with horizontal synchronization frequency from the
display, which might cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronization frequency and its harmonics as
far as possible.

(b) When the effective ignition length becomes ≦ 80% of its original value.
(The effective ignition length is a scope that luminance is over 80% of that at the
center point.)
Note (6) The waveform of the voltage output of inverter must be area-symmetric and the design of the
inverter must have specifications for the modularized lamp. The performance of the Backlight,

such as lifetime or brightness, is greatly influenced by the characteristics of the DC-AC inverter for
the lamp. All the parameters of an inverter should be carefully designed to avoid producing too
much current leakage from high voltage output of the inverter. When designing or ordering the
inverter please make sure that a poor lighting caused by the mismatch of the Backlight and the
inverter (miss-lighting, flicker, etc.) never occurs. If the above situation is confirmed, the module
should be operated in the same manners when it is installed in your instrument.
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.
Requirements for a system inverter design, which is intended to have a better display performance, a
better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its
leakage current.
a. The asymmetry rate of the inverter waveform should be 10% below;
b. The distortion rate of the waveform should be within √2 ± 10%;
c. The ideal sine wave form shall be symmetric in positive and negative polarities

5.4 COLOR DATA INPUT ASSIGNMENT
The brightness of each primary color (red, green and blue) is based on the 8-bit gray scale data input for
the color. The higher the binary input, the brighter the color. The table below provides the assignment of
