1. General Description
The LH350H01 is a Color Active Matrix Liquid
Crystal Display. The matrix employs a-Si Thin
Film Transistor as the active element. It is a
transflective type display operating in the
normally white mode. This model is a diagonal
3.54 inch with the portrait typed hVGA
(320xRGBx480) resolution. Each pixel is divided
into blue, green and red sub-pixels or dots which
are arranged in vertical stripes. The LH350H01 is
intended to support applications where thin
thickness, low power are critical factors and
graphic display are important. In combination
with the vertical arrangement of the sub-pixels,
the LH350H01 characteristics provide a high
quality display for mobile phone application.

the reference value. In order to get the
optimized display quality, the setting-voltage
should be changed as based on customer's
developing condition. (The display quality could
be changed by customer's setting-voltage.)

30 minutes in a dark environment at 25 C. The
values specified are at an approximate distance
50 cm from the TFT-LCD surface at a viewing
angle of 0 .

Notes
1. Contrast Ratio(CR) is defined mathematically
as
Surface Luminance with all white pixels
Contrast Ratio
Surface Luminance with all black
pixels 2. Surface luminance is the center point
across the TFT-LCD surface 500 mm from the
surface with all pixels displaying white.
For more information see FIG 1. 3. Response time
is the time required for the display to
transition from white to black(Rise Time, Tr)
and from black to white(Falling Time, Tf). For
additional information see FIG 3. 4. Viewing
angle is the angle at which the contrast ratio is
greater than 10. The angles are determined
for the horizontal or x axis and the vertical or
y axis with respect to the z axis which is
normal to the TFT-LCD surface. For more
information see FIG 4. 5. Optimum contrast is
obtained by adjusting the TFT-LCD Threshold

8. PRECAUTIONS
Please pay attention to the following when you
use this TFT-LCD panel.
8-1. MOUNTING PRECAUTIONS
1) When the surface becomes dusty, please
wipe gently with absorbent cotton or
other soft materials. 2) Since a TFT-LCD
Panel is composed of electronic circuits, it is
not strong to electrostatic discharge.
Make certain that treatment persons are connected
to ground through wrist band etc .
3) Do not leave at the high temperature and
high humidity in long time. 4) Do not leave
the TFT-LCD panel from direct sunlight. 5)
Do not contact with water to avoid Metal
corrosion. 6) The TFT-LCD Panel shall be
installed flat, without twisting or bending
8-2. OPERATING PRECAUTIONS
1) The spike noise causes the mis-operation of
circuits. It should be lower than following
voltage V200mV(Over and under shoot
voltage) 2) Response time depends on the
temperature.(In lower temperature, it becomes
longer.) 3) Brightness depends on the
temperature. (In lower temperature, it becomes
lower.) And in lower temperature, response
time(required time that brightness is stable
after turned on) becomes longer. 4) Be
careful for condensation at sudden temperature
change. Condensation makes damage to
polarizer or electrical contacted parts. And
after fading condensation, smear or spot will
occur. 5) When fixed patterns are displayed for a
long time, remnant image is likely to occur. 6)
The TFT-LCD shall be operated within the
temperature limits specified. when you operate
the TFT-LCD panel at below(beyond) the limit
specified,It may cause damage or image
degradation. This phenomenon may not recover.
8-3. ELECTROSTATIC DISCHARGE CONTROL
Since a module is composed of electronic
circuits, it is not strong to electrostatic
discharge. Make certain that treatment persons
are connected to ground through wrist band etc.
And dont touch interface pin directly.
18
8-4. PRECAUTIONS FOR STRONG LIGHT EXPOSURE
Strong light exposure causes degradation of color
filter. It may not recover
8-5. STORAGE
When storing TFT-LCD panel as spares for a long
time, the following precautions are necessary. 1)
Store them in a dark place. Do not expose to
sunlight or fluorescent light. Keep the
temperature between 5C and 35C at normal
humidity. 2) The TFT-LCD glass surface should not
come in contact with any other object. It is
recommended that they be stored in the container
in which they were shipped. 3) As TFT-LCD panels
are packed in a vacuum with PE bag and Al bag in
Nitrogen gas environment , Customer is
required to keep the product under a good
condition(25 degree, 50) to prevent any of
unwanted damage from the moisture, and chemicals,
etc. And recommended to use it in a short-time
period, after it's unpacked.
8-6. HANDLING PRECAUTIONS FOR TFT-LCD Glass
Be careful when TFT-LCD panel is broken.(TFT-LCD
is made of glass)
