Note 1) Refer to TIMING CHART at page4 and LVDS specification (DS90CF384) by National Semiconductor Corporation.
Note 2) When ENAB is fixed to “H” level or “L” level after NCLK input, the panel is displayed as black. However, it may be
occurred a flicker on the display.
Note 3) When NCLK is fixed to “H” level or “L” level, the panel becomes white stage after several seconds.
Note 4) Do not change t1 and t3 values in the operation. When t1 or t3 is changed, the panel is displayed as black.
Note 5) 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).

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 lifesupport systems.
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.
7)
DISPOSAL
When dispose LCD module, obey to the applicable environmental regulations.
