Note (1) The above specification is not for the converter output, but for the LED bar.

- The LED bar consists of 39 LED packages ; 3 parallel X 13 serial

- LED current is defined at 100% duty ratio of LED driver

(2) The LED Forward current for single LED channel is Typ.125mA

- The output current of converter in the system should be transmitted to the LED

bar constantly.

- It is recommended to control the returned signal respectively for even
distribution of current to each channel of LED bar

(3) The power consumption is specified at typical current 375mA with 100% duty ratio

- It does not include power loss of external LED driver circuit block

- Typical power consumption P

(4) Life time(Hr) is defined as the time when brightness of a LED package itself

becomes 50% or less than its original value at the condition of Ta=25 ± 2°C

and IF =375mA.

8. General Precautions

8.1 Handling Precautions

A. When assembling LCD module into its system, using all the mounting holes is

strongly suggested.

B. Keep LCD module from any external shock or force which can cause physical damage

to LCD module. It may cause improper operation or damage to LCD module.

C. Polarizer films are very fragile. It could be damaged easily. Do not press or scratch

the surface harder than a HB pencil lead.

D. Wipe off water droplets or oil immediately. Water drops or oils can cause permanent

stain or discoloration.

E. To clean LCD module, please use IPA (Isopropyl Alcohol) or Hexane.

F. Do not use ketone type material (ex. Acetone), ethyl alcohol, toluene, ethyl acid or

methyl chloride. Using these could cause permanent polarizer damage to the LCD
module.

G. If the liquid crystal leaks from LCD module, keep it away from human eyes or mouth.

In case of contact with human body or clothes, it should be washed with soap thoroughly.

H. Protect LCD module from static discharge.

I. To keep the LCD module clean, make sure to wear fabric gloves and finger coats when
you are inspecting and/or assembling the unit.

J. Do not disassemble LCD module.

K. Protection film on LCD module display area should be slowly peeled off just before

assembly to prevent static discharge.

L. Pins of the Interface connector should not be touched directly with bare hands.

8.3 Operating Precautions

A. If the module is used to other applications besides the recommendation on General

Description, please contact SAMSUNG for application engineering device in advance

B. Do not connect or disconnect the LCD module when it is set to the “Power On”

condition.

C. Input power should always follow ‘5.6 Power on/off sequence’

D. Polarizer films are very fragile. It could be damaged easily. Do not press or scratch the

Polarizer films

E. LCD module contains electrical circuits that operate in high frequencies. To minimize

electromagnetic interference, be sure to sufficiently ground and shield the LCD module and
system.

F. If LCD module containing system is out of SAMSUNG ’s operating condition,

SAMSUNG can not guarantee LCD module operating properly.

G. If the product will be used in extreme conditions such as high temperature, humidity,

display patterns, operation time, etc., it is strongly recommended to contact SAMSUNG for
application engineering device. Otherwise, the reliability and function

of the module may not be guaranteed. Extreme conditions are commonly found at

airports, transit stations, banks, stocks, markets, and controlling systems.

H. Ultra-violet ray filter is necessary for outdoor operation.

I. If the module keeps displaying the same pattern for a long period of time, the image

maybe burned in to the screen. To avoid image retention, it is recommended to use a
screen saver.

J. This module has its PCB’s circuitry on the rear side and should be handled carefully in

order to avoid stress.

K. Please contact SAMSUNG beforehand, if you plan to display the same pattern for a

long period of time.

L. Any foreign materials brought into an LCD module by external forced-airflow are not

guaranteed by SAMSUNG .

9.4 Design Guide for System

8.4 Design Guide for System

A. The LED driver should be designed in compliance with the specifications of LED bar strictly to

make the LED in LCD module perform as expected

B. It is recommended that you locate the rib on the front or rear cover not to be placed on the

spot where D-IC is located on the upper or left of LCD module.

C. It is recommended that assemble the bracket which has two sides with holes for assembly.

D. It is recommended that you design the bracket with the structure which covers the sides

of module when designing the bracket for customer.

E. It is recommended that you design the bracket not to be interfered with the SET at the area

where the PBA of module is located.

F. It is recommended that more than 0.3 mm is allowable as a gap between the metal case

and the rear of module.

G. It is recommended that structure to support the module shall be far away 10mm from the

edge of border.

where is far away 10mm from the edge of border.

I. When applying the measures described below to reduce the level of EMI which occurs

between the metal cover and the rear of module.

J. If you use Finger, less than 0.3mm is allowable for overlap.

K. It is recommended that more than 0.3mm gap between the front case (or cover) and

the panel glass is allowable.
