Assembly Precautions; Operating Precautions - Himedia HM-LC43R15J Manual

9.2.2 Assembly Precautions

(a) Remove the stains with finger-stalls wearing soft gloves in order to keep the display clean in the
process of the incoming inspection and the assembly process. When the surface becomes dusty, please
wipe gently with absorbent cotton or other soft materials like chamois soaks with petroleum benzene.
Normal-hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. Do not
use acetone, toluene and alcohol because they cause chemical damage to the polarizer.
(b) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB
pencil lead. And please do not rub with dust clothes with chemical treatment. Do not touch the surface of
polarizer with bare hands or greasy clothes. (Some cosmetics are detrimental to the polarizer.)
(c) Use the tray to transport open cell can prevent open cell broken and electrical components damage.
(d) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to
the cell. And the frame on which a cell is mounted should have sufficient strength so that external force is
not transmitted directly to the cell.
(e) Be careful not to give any extra mechanical stress to the panel when designing the set, and BLU kit.
(f) Do not use cover case which made of acetic acid type and chlorine type materials because acetic acid
type materials generates corrosive gas which will damage the polarizer at high temperature and chlorine
type materials causes circuit break by electro-chemical reaction.
(g) When the panel kit and BLU kit are assembled, the panel kit and BLU kit should be attached to the set
system firmly by combining each mounted holes. Be careful not to give the mechanical stress.
Electrostatic discharge may easily damage the electronic circuits on the open cell unit. Make certain that
treatment persons are grounded, (ex : anti-static wristband or etc. ) and don't touch interface pin directly.
9.2.3 FFC & PCB Precautions
(a) Refrain from applying any forces to the source PCB and the drive IC in the process of the handling or
installing to the set. If any forces are applied to the product, it may cause damage or a malfunction in the
panel kit.
(b) Do not pull, fold or bend the source COF and the gate COF in any processes.
(c) This panel has its circuitry of PCB's on the rear side, so it should be handled carefully in order for a
force not to be applied.
(d) Do not touch the pins of the interface connector directly with bare hands.
(e) The connector is a precision device to connect PCB and transmit electrical signals. Operators should
plug/un-plug the connector in parallel way during module assembly.
(f) The cables between TV SET connector and Control PCB interface should be connected directly to have
a minimized length. A longer cable between TV SET connector and Control PCB interface maybe operate
abnormal display.
9.2.4 Flicker adjust
In order to prevent potential problems, flicker should be adjusted by optimizing the Vcom value in customer
LCM Line through the 12C Interface. Detail settings please refer to appendix section.
9.3 Aging
Be sure to age for over 1 hour at least, which the product is driving initially to stabilize TFT
Characteristic.

9.4 Operating Precautions

(a) Be cautious not to give any strong mechanical shock or any forces to the panel kit. Applying any forces
to the panel may cause the abnormal operation or the damage to the panel kit and the back light unit
kit.
