Please
carefully follow the appropriate product specification and other documents
for proper usage, safety handling, and operation standards for maximum
performance.
TFT panels are made of glass and contain liquid crystal materials
• Please avoid breaking the TFT panel to prevent injury from sharp glass
particles.
• It is recommended to allow sufficient open space surrounding the TFT panel
to avoid possible damage.
• Please design the mounting of the TFT module to have within 0.3 mm warping
tolerance to avoid any forces that may damage the display due to PCB
distortion causing a breakdown of the electrical circuit leading to TFT
module failure.
Conducting voltage
• Avoid touching conductive electrical parts with other conductive materials
because the TFT-module may be damaged.
• Even when electric power is turned off, it may take more than one minute
for the electrical current to discharge.
Cable connection
• Do not unplug the power and/or data cables of TFT modules during operation
because unrecoverable damage may result.
• Sending input signals to the TFT module during a power off condition
sometimes causes I/O port damage.
• It is recommended to use a 30 cm or shorter signal cable to prevent
functional failures subject to port application.
Electrostatic charge
• TFT modules require electrostatic free packaging and protection from
electrostatic charges during handling and usage.
Structure
• During operation, TFT panels and TFT modules generate heat. Please
consider sufficient heat radiation dissipation.
• We prefer to use UL grade materials or components in conjunction with TFT
modules.
• Wrap and twist motion causes stress and may break TFTs and TFT modules.
Please adhere to allowances within 0.3mm at the point of attachment.
Power
• Apply regulated power to the TFT module within the specified voltages to
protect from failures.
• A TFT module may consume an in rush current equal to twice the typical
current at power-on due to capacitor charging.
We recommend using a power supply capable of quick starting.
• TFT-module needs a specified voltage at the point of connection. Please
use an adequate power cable to avoid a decrease in voltage. We recommend the
provision of a fuse since the onboard TFT module fuse is SMT soldered.
Operating consideration
• The LED backlight will decrease in brightness during extended operation.
If a fixed pattern illuminates on a TFT panel for an extended period, this
will result in a retained ghost image. Please consider a screen safer to
reduce this effect.
• We recommend using a signal cable 30cm or less to avoid noise with a
ferrite fitted to reduce emission.
Storage and operating environment
• Please use TFT-modules under the recommended specified environmental
conditions. Salty, sulfur and dusty
environments may damage the TFT module even during storage.
Disposal
• When discarding TFTs or TFT modules, please adhere to governmental related
laws or regulations.
Others
• Although the TFT modules are designed to be protected from electrical
noise, please plan your circuitry to exclude as much noise as possible.
• Do not reconstruct or repair the TFT module without our authorization. We
cannot assure the quality or reliability of
unauthorized repaired TFT modules.
