(Note31 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.
[Noted] Lamp life time(Ll.) is defined as the time when either 0 or Q) occurs in the
continuous operation under the condition of Ta=25’Cand 11.=5.SmArms.
Q Brightness becomes 50% of the original value.
@I Kick-off voltage at Ta=O’C exceeds maximumvalue. 1000 Vrms.
Note) The performance of the backlight. for example life time or brightness, is much
influenced by the characteristics
of the DC-ACinverter for the lamp. lhen 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
occur. Whenyou confirm it, the module should be operated in the same condition as
it is installed in your instrument.

Yhen ENAB is fixed “‘Low”. the display starts from the data of ClO4(clock) as shown
in Fig. 2-Q-Q.
Be careful that the module do noJ work when ENABis fixed “High’.
7-3. Vertical display position
The vertical display position is automatically centered in the active area at each
mode of VGA. 480-, 400- and 350-line mode. Each mode is selected depending on the
polarity of the synchronous signals described in 4-l (Notel).
In each mode, the data of TVn is displayed at the top line of the active area. And
the display position will be centered on the screen like the following figure when the
period of vertical synchronous signal. TV. is typical value.
In 400- and 350-line mode. the data in the vertical data invalid period is also
displayed. So, inputting all data “0” is recommendedduring vertical data invalid

ENAB signal has no relation to the vertical display position.

11. Handling Precautions
a) Laminated film is attached to the module surface to prevent it from being scratched.
Peel the film off slowly. just before the use. with strict attention to electrostatic
changes. Ionized air shall be blowed over during the action. Blow off ‘dust’ on the
polarizer by using an ionized nitrogen gun. etc.
b) Be sure to turn off the power supply and signal when inserting or disconnecting the
cable.
c) Since LCD panel is made of glass. it may break or crack if it’s dropped or bumped.
Handle with care.
d) The thin liquid crystal layer is packed in the LCD panel. This layer may be disturbed
by the external force when the panel surface is pushed strongly and this disturbance
may cause the transient display non-uniformity. So do not push the panel surface so
strongly.
e) Be sure to design the cabinet so that the module can be instalied without any extra
stress such as warp or twist.
f) Since the front polarizer is easily damaged. pay attention not to scratch it.
Long contact with water may cause discoloration
g) lipe off water drop immediately.
or spots.
h) Rhen the panel surface is soiled. wipe it with absorbent cotton or other soft cloth.
i) Since CMOSLSIs are used in this module. take care of static electricity
and ensure the
humanearth when handling.
j,) Observe all other precautionary requirements in handling co?ponents.
12. Packing form
a) Piling number of cartons : MAX. 7

b) Package quantity in one carton : MX. 10
c) Carton size : 374(1)xZ54(HJx314!D)mm
