[Note 9-4] A measurement device is Minolta CM-2002.
[Note 9-5] Definition of reflection ratio
Reflection ratio =
[Note 9-6] A measurement device is ELDIM EZContrast
[Note 9-7] This is the reference value. The White-LED life time is defind as a time when brightness not to become
under 50% of the original value(at Ta=25ㄏ)
(10) Display quality
The display quality of the color TFT-LCD module shall be in compliance with
the Incoming Inspection Standards for TFT-LCD.
(11)Mechanical characteristics
11-1) External appearance
See Fig. 1
11-2) FPC (for LCD panel) characteristics
(1)Specific connector
FH12-50S-0.5SH(55) (HIROSE)
(2) Bending endurance of the bending slits portion
No line of the FPC is broken for the bending test (Bending radius=0.6mm and
angle=90°) in 30 cycles.
(12)Handling Precautions
a) Be sure to turn off the power supply when inserting or disconnecting the FPC.
b) Please insert FPC in the connector carefully so that the tension should not hang.
c) The FPC for LCD panel shall be bent only slit portion. The bending slit shall be bent uniformly on the whole
slit portion with bending radius larger than 0.6mm ,and only inner side (back side of the module). Don’t bend
it outer side (display surface side). Do not give the FPCs too large force, for example, hanging the module with
holding FPC.
d) Be sure to design the cabinet so that the module can be installed without any extra stress such as warp or
twist.
e) Since the front polarizer is easily damaged, pay attention not to scratch it. Blow away dust on the polarizer
with antistatic ╁2 blow. It is undesirable to wipe off because a polarizer is sensitive. It is recommended to
peel off softly using the adhesive tape when soil or finger oil is stuck to the polarizer. When unavoidable, wipe
off carefully with a cloth for wiping lenses.
f) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.
g) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
h) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with
care.
i) Liquid crystal contained in the panel may leak if the LCD is broken. Rinse it as soon as possible if it gets
inside your eye or mouth by mistake.
j) Since CMOS LSI is used in this module, take care of static electricity and injure the human earth when
handling. Observe all other precautionary requirements in handling components.
k) In case of attaching protective board over the LCD, be careful about the optical interface fringe etc. which
degrades display quality.
