11. Using LCD modules
11.1 LIQUID CRYSTAL DISPLAY MODULES
LCD is composed of glass and polarizer. Pay attention to the following items when handling.
(1) Please keep the temperature within specified range for use and storage. Polarization degradation,
bubble generation or polarizer peel-off may occur with high temperature and high humidity.
(2) Do not touch, push or rub the exposed polarizers with anything harder than a HB pencil lead (glass,
tweezers, etc).
(3) N-hexane is recommended for cleaning the adhesives used to attach front/rear polarizers and
reflectors made of organic substances, which will be damaged by chemicals such as acetone,
toluene, toluene, ethanol and isopropyl alcohol.
(4) When the display surface becomes dusty, wipe gently with absorbent cotton or other soft material
like chamois soaked in petroleum ether. Do not scrub hard to avoid damaging the display surface.
(5) Wipe off saliva or water drops immediately, contact with water over a long period of time may
cause deformation or color fading.
(6) Avoid contacting oil and fats.
(7) Condensation on the surface and contact with terminals due to cold will damage, stain or
polarizers. After products are tested at low temperature they must be warmed up in a container
before coming is contacting with room temperature air.
(8) Do not put or attach anything on the display area to avoid leaving marks on.
(9) Do not touch the display with bare hands. This will stain the display area and degrade insulation
between terminals (some cosmetics are determinate to the polarizers).
(10)As glass is fragile, it tends to become or chipped during handling especially on the edges. Please
avoid dropping or jarring.
11.2 INSTALLING LCD MODULE
Attend to the following items when installing the LCM.
(1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
(2) When assembling the LCM into other equipment, the spacer to the bit between the LCM and the
fitting plate should have enough height to avoid causing stress to the module surface, refer to the
individual specifications for measurements. The measurement tolerance should be ±0.1mm.
11.3 ELECTRO-STATIC DISCHARGE CONTROL
Since this module uses a CMOS LSI, the same careful attention should be paid for electrostatic
discharge as for an ordinary CMOS IC.
