General Description

Samsung Secret

Description

LSJ550HW01 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. The resolution of a 60“ is 1920 x 1080 and this model can

display up to 1.07 billion colors with wide viewing angle of 89° or higher in all directions.

This panel is intended to support applications to provide a excellent performance for Flat

Panel Display such as Home-alone Multimedia TFT-LCD TV and High Definition TV.

Features

 High contrast & aperture ratio with wide color gamut
 SVA (Super Vertical Align) mode
 Wide viewing angle (±178°)
 High speed response
 FHD resolution (16:9)
 LVDS (Low Voltage Differential Signaling) interface (2pixel/clock)
 2D / 3D function compatible

- The measurement shall be executed 60 minutes after lighting at rating.

- Test Equipment Setup
The measurement should be executed in a stable, windless and dark room between

40min and 60min after lighting the back light at 25 ± 2°C for stabilization

of the back light. This should be measured in the center of screen.

6.3 Power ON/OFF Sequence

To prevent a latch-up or DC operation of the LCD Module, the power on/off

sequence should be as the diagram below.

0.5<T1≤10ms

1<T2≤50ms

0<T3≤50ms

1000ms≤T4

1000ms≤T5

100ms≤T6

T1 : VDDrising time from 10% to 90%
T2 : The time from VDDto valid data at power ON.
T3 : The time from valid data off to VDDoff at power Off.
T4 : VDDoff time for Windows restart
T5 : The time from valid data to B/L enable at power ON.
T6 : The time from valid data off to B/L disable at power Off.

 The supply voltage of the external system for the Module input should be the same

as the definition of VDD.

 Apply the lamp voltage 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.

 In case of VDD= off level,

please keep the level of input signals low or keep a high impedance.

 T4 should be measured after the Module has been fully discharged between power off

and on period.

 Interface signal should not be kept at high impedance when the power is on.

10. General Precautions

Samsung Secret

10.1 Handling

(a) When the Module is assembled, it should be attached to the system firmly

using all mounting holes. Be careful not to twist and bend the Module.

(b) Because the inverter use high voltage, it should be disconnected from power

before it is assembled or disassembled.

(c) Refrain from strong mechanical shock and / or any force to the Module.

In addition to damage, this may cause improper operation or damage to the Module

and CCFL back light.

(d) Note that polarizers are very fragile and could be damage easily.

Do not press or scratch the surface harder than a HB pencil lead.

(e) Wipe off water droplets or oil immediately. If you leave the droplets for a long

time, staining or discoloration may occur.
(f) If the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth.
(g) Desirable cleaners are water, IPA(Isopropyl Alcohol) or Hexane.

Do not use Ketone type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid

or Methyl chloride. It might permanent damage to the polarizer due to chemical

reaction.
(h) If the liquid crystal material leaks from the panel, it should be kept away

from the eyes or mouth . In case of contact with hands, legs or clothes, it must

be washed away with soap thoroughly.
(i) Protect the module from Electrostatic discharge. Otherwise the ASIC IC or

Semiconductor would be damaged.

(j) Use finger-stalls with soft gloves in order to keep display clean during the

incoming inspection and assembly process.

(k) Do not disassemble the Module.
(l) Do not disassemble shield case of inverter & LVDS board.
(m) Do not connect N.C pins. (Samsung internal use only)
(n) Protection film for polarizer on the Module should be slowly peeled off just before use

so that the electrostatic charge can be minimized. Must put on antistatic glove while

handle a module
(o) Pins of I/F connector should not be touched directly with bare hands.

Storage Life 12 Months

- The storage room should provide good ventilation and temperature

control.

- Products should not be placed on the floor, but on the Pallet away

from

a wall.

- Prevent products from direct sunlight, moisture nor water; Be

cautious of

Storage

Condition

a build up of condensation.

- Avoid other hazardous environment while storing goods.

- If products delivered or kept in conditions of over the storage period

of 3

months, the recommended temperature or humidity range,
we recommend you leave them at a temperature of 20℃ and a

humidity

of 50% for 24 hours.

10.3 Operation

(a) Do not connect or disconnect the Module in the "Power On" condition.

(b) Power supply should always be turned on/off by the "Power on/off sequence"

(c) Module has high frequency circuits. Sufficient suppression to the electromagnetic

interference should be done by system manufacturers. Grounding and shielding methods
may be important to minimize the interference.

(d) The cable between the back light connector and its converter power supply should

be connected directly with a minimized length. A longer cable between the back light
and the converter may cause lower luminance of LED and may require higher startup
voltage(Vs).

10.4 Operation Condition Guide

Samsung Secret

(a) The LCD product should be operated under normal conditions.

Normal condition is defined as below;

- Temperature : 20±15℃

- Humidity : 55±20%

- Display pattern : continually changing pattern (Not stationary)

(b) If the product will be used in extreme conditions such as high temperature,

humidity, display patterns or operation time etc.., It is strongly recommended
to contact SEC for Application engineering advice. Otherwise, its reliability and
function may not be guaranteed. Extreme conditions are commonly found at

Airports, Transit Stations, Banks, Stock market, and Controlling systems.

10.5 Others

(a) Ultra-violet ray filter is necessary for outdoor operation.

(b) Avoid condensation of water. It may result in improper operation or disconnection

of electrode.

(c) Do not exceed the absolute maximum rating value. ( supply voltage variation,

input voltage variation, variation in part contents and environmental temperature,
and so on)
Otherwise the Module may be damaged.

(d) If the Module keeps displaying the same pattern for a long period of time,

the image may be "sticked" to the screen.

To avoid image sticking, it is recommended to use a screen saver.

(e) This Module has its circuitry PCB's on the rear side and should be handled

carefully in order not to be stressed.

(f) Please contact SEC in advance when you display the same pattern for a long time.
