Note 1) Refer to TIMING CHART and LVDS (DF90CF364MTD) specifications by National Semiconductor.

Note 2) If NCLK is fixed to "H" or "L" level for certain period, the panel may be damaged.

Note 3) Please adjust LCD operating signal timing and FL driving frequency, to optimize the display quality.

There is a possibility that flicker is observed by the interference of LCD operating signal timing and FL driving

Condition (especially driving frequency ), even if the condition satisfies above timing specifications and
recommended operating conditions shown in 3.

Notes 4) Do not hold NCLK on “H” level nor “L” level during VDD(+3.3V) Is supplied. When it holds on, DC voltage supplies

to liquid crystal materials and it may cause damage to liquid crystal materials.

Notes 5) These values are determined by the LCD module.

FOR SAFETY

LCD module is generally designed with precise parts to achieve light weighted thin mechanical dimensions.
In using our Modules, make certain that you fully understand and put into practice the warnings and safety precautions detailed
in Engineering Information No.EE-N001,"CAUTIONS AND INSTRUCTIONS FOR TOSHIBA LCD MODULES".
Refer to individual specifications and TECHNICAL DATA sheets (hereinafter called "TD") for more detailed technical information.

1) SPECIAL PURPOSES

A) Toshiba's Standard LCD Modules have not been customized for operation in extreme environments or for use in applications
where performance failures could be life-threatening or otherwise catastrophic.

B) Since Toshiba's Standard LCD Modules have not been designed for operation in extreme environments, they must never be
used in devices that will be exposed to abnormally high levels of vibration or shock which exceed Toshiba's published
specification limits.

C) In addition, since Toshiba Standard LCD Modules have not been designed for use in applications where performance failures
could be life-threatening or catastrophic, they must never be installed in aircraft navigation control systems (such as, but not
limited to Traffic Collision Avoidance System and Air Traffic Indicator), in military defense or weapons systems, in critical
industrial process-control systems (e.g., those involved in the production of nuclear energy), or in critical medical device or
patient life-support systems.

www.panelook.com

LTM12C324S

2) DISASSEMBLING OR MODIFICATION

DO NOT DISASSEMBLE OR MODIFY the module. It may damage sensitive parts inside LCD module, and may cause
scratches or dust on the display.
Toshiba doses not warrant the module, if customer disassembled or modified it.

3) BREAKAGE OF LCD PANEL

DO NOT INGEST liquid crystal material, DO NOT INHALE this material, and DO NOT CONTACT the material with skin, if LCD
panel is broken and liquid crystal material spills out.
If liquid crystal material comes into mouth or eyes, rinse mouth or eyes out with water immediately.
If this material contact with skin or cloths, wash it off immediately with alcohol and rinse thoroughly with water.

4) GLASS OF LCD PANEL

BE CAREFUL WITH CHIPS OF GLASS that may cause injuring fingers or skin, when the glass is broken.

5) ELECTRIC SHOCK

DISCONNECT POWER SUPPLY before handling LCD module.
DO NOT TOUCH the parts inside LCD module and the fluorescent lamp's connector or cables in order to prevent electric shock,
because high voltage is supplied to these parts from the inverter unit while power supply is turned on.

6) ABSOLUTE MAXIMUM RATINGS AND POWER PROTECTION CIRCUIT

DO NOT EXCEED the absolute maximum rating values under the worst probable conditions caused by the supply voltage
variation, input voltage variation, variation in parts' constants, environmental temperature, etc., otherwise LCD module may be
damaged.
Employ protection circuit for power supply, whenever the specification or TD specifies it.
Suitable protection circuit should be applied for each system design.

DISPOSAL

7)

When dispose LCD module, obey to the applicable environmental regulations.
