It is recommended to consider some timing difference between LVDS input and Backlight input as
shown above.
If the Backlight lights on before LCD starting, or if the Backlight is kept on after LCD stopping, the
screen may look white for a moment or abnormal image may be displayed. This is caused by variation in
output signal from timing generator at LVDS input on or off. It does not cause the damage to the LCD
module.

Note3 Lamp frequency may produce interference with horizontal synchronous frequency, and this may cause beat on
the display. Therefore lamp frequency shall be detached as much as possible from the horizontal synchronous frequency
and from the harmonics of horizontal synchronous to avoid interference.
rise up in the user set, please decide the open output voltage by checking not to occur lighting failure
under operating state. The open output voltage should be applied to the lamp for more than 1 second to startup.
Otherwise the lamp may not be turned on.

Note
The performance of the backlight, for example lifetime or brightness, is much influenced by the characteristics of the
DC-AC inverter for the lamp. When you design or order 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. When you confirm it, the module should
be operated in the same condition as it is installed in your instrument.
Use the lamp inverter power source incorporating such safeguard as overvoltage / overcurrent protective circuit or lamp
voltage waveform detection circuit, which should have individual control of each lamp. In case one circuit without such
individual control is connected to more than two lamps, excessive current may flow into one lamp when the other one is not in
operation.
Under the environment of 101x or less,miss-lighting or lighting delay may occur..

Note5 Definition of white uniformity:
White uniformity is defined as the following with five measurements (A E).
10. Handling Precautions
a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) Be sure to design the cabinet so that the module can be installed without any extra stress such as warp or
twist.
c) Since the front polarize is easily damaged, pay attention not to scratch it.
d) Since long contact with water may cause discoloration or spots, wipe off water drop immediately.
e) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
f) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle
with care..
g) Since CMOS LSI is used in this module, take care of static electricity and take the human earth into
consideration when handling.
h) Make sure the four mounting holes of the module are grounded sufficiently. Take electro-magnetic
interference (EMI) into consideration.
i) The module has some printed circuit boards (PCBs) on the back side. Take care to keep them form any
stress or pressure when handling or installing the module; otherwise some of electronic parts on the
PCBs may be damaged.
j) Observe all other precautionary requirements in handling components.
k) Since it is necessary to remove the screw on the back of a module before performing lamp exchange,
please take a cabinet design into consideration.
l) When some pressure is added onto the module from rear side constantly, it causes display non-uniformity
issue, functional defect, etc. So, please avoid such design.
m) When handling LCD modules and assembling them into cabinets, please be noted that long-term
storage in the environment of oxidization or deoxidization gas and the use of such materials as reagent,
solvent, adhesive, resin, etc. which generate these gasses, may cause corrosion and discoloration of the
LCD modules.
