1. General DescriptionG

Overview G

LTM240CL02 is a color active matrix liquid crystal display (LCD) that uses amorphous
silicon TFT (Thin Film Transistor) as switching components. This model is composed of a
TFT LCD panel, a driver circuit and a back light unit. The resolution of a 24.0” is 1920 x
1200 (WUXGA) and this model can display up to 16.7 million colors.

Features

- Workstation & Desktop monitors

- Display terminals for AV Products

6.0 compliance

www.panelook.com

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

- LED bar : 2 ea ( 2 side Edge )

- The LED bar consists of Magenta 36 LED packages (3 parallel X 12 serial) &
Green 36 LED packages (3 parallel X 12 serial)

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

(2) The LED Forward current for single LED channel is Typ.58mA ( Magenta )

& Typ.75mA ( Green )

- 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 174mA ( Magenta ) &

225mA ( Green ) with 100% duty ratio

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

- Typical power consumption

Note (1) The supply voltage of the external system for the Module input should be

the same as the definition of VDD.

(2) Apply the BLU power within the LCD operation range. When the back light

turns on before the LCD operation or the LCD turns off before the back light
turns off, the display may momentarily show abnormal screen.

(3) In case of V

please keep the level of input signals low or keep a high impedance.
(4) T4 should be measured after the Module has been fully discharged between
power off and on period.

(5) Interface signal should not be kept at high impedance when the power is on.

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 .

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

( See ‘6. Outline Dimension ’ for the exact location of driver ICs )

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. D. 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.

H. It is recommended that metal case (or board) shall be affixed to the rear case at the spot

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.

The thickness of EMI gasket should be less than 1.1 times (110%) of the gap between
System metal case and LCD module.

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

panel glass is allowable.
