Notes on Handling
(1) Static charge prevention
Be sure to take the following protective measures. TFT-LCD panels and LED backlights are easily damaged
by static charges.
a) Use non-chargeable gloves, or simply use bare hands.
b) Use an earth-band when handling.
c) Do not touch any electrodes of a panel.
d) Wear non-chargeable clothes and conductive shoes.
e) Install grounded conductive mats on the working floor and working table.
f) Keep panels away from any charged materials.
g) Use ionized air to discharge the panels.
(2) Protection from dust and dirt
a) Operate in a clean environment.
b) When delivered, the panel surface (Polarizer) is covered by a protective sheet. Peel off the protective
sheet carefully so as not to damage the panel.
c) Do not touch the polarizer surface. The surface is easily scratched. When cleaning, use a clean-room
wiper with isopropyl alcohol. Be careful not to leave stains on the surface.
d) Use ionized air to blow dust off the panel.
(3) Module fixing method
a) The following items should be taken into account for the positioning guide design.
• The design reference edges are the upper and left edges of the panel as viewed from the front.
Design the guides using the panel frame as the reference and not the backlight.
• Set the guides on the same side of the set as the monitor window frame.
• To prevent LCD image unevenness, the guides should be the maximum package tolerance or more
so that a clasping load is not applied to the panel from the x and y directions.
• Make sure the guides do not block the panel FPC outlet and backlight lead wire outlet.
b) The guaranteed area of the polarizer is the outer circumference of 0.7mm of the effective display area
(Fig. 1). Design the monitor window frame of the set so that it is within this range including variance.
c) Set the holders on the rear of the backlight around the circumference as far from the center of the
backlight as possible. Local pressure applied to the center of the rear of the backlight for an extended
period may result in uneven luminance, so the holder pressure on the center of the backlight should be
500g/cm² or less.
d) Connect the panel or backlight frame to GND.
e) Use a design that does not repeatedly bend or place stress on the backlight lead wires (maximum load
in the lead wire pull-out direction: 500g) as this may cause lead wire disconnection at the solder
junction on the backlight unit side. (Forced bending of 90° or more is permitted up to 2 times, and
repeated bending of 45° up to 8 times.)
