General Description

Samsung Secret

Description

LSC400HM03 is a color active matrix liquid crystal display (LCD) that uses amorphous

silicon TFT (Thin Film Transistor) as switching components. The resolution of a 40.0“ is

1920 x 1080 and this model can display up to 16.7 Million 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

 RoHS compliance (Pb-free)
 High contrast ratio & aperture ratio with wide color gamut

 SPVA(Super Patterned Vertical Align) mode

 Wide viewing angle (±178°)
 High speed response

 FHD resolution (16:9)

 Low Power consumption
 DE (Data Enable) mode
 2ch LVDS (Low Voltage Differential Signaling) interface (2pixel/clock)

5.4 Power ON/OFF Sequence

Samsung Secret

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

sequence should be as the diagram below.

2 msec<T1≤10msec

0<T2≤50msec
0<T3≤50msec
1000msec≤T4

1000msec≤T5

(Recommend Value)

100msec≤T6

(Recommend Value)

0.5 Vcc

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.

 In Case T5 is less than 1000msec and T6 is less than 100msec,

Garbage Display can be seen. (It is not related to electrical function issue, Just for
recommendation to prevent Garbage Display )

10. General Precautions

Samsung Secret

10.1 Handling

(a) When the module is assembled, It should be attached to the system firmly using

every mounting holes. Be careful not to twist and bend the modules.

(b) 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 back-light.

(c) Note that polarizers are very fragile and could be easily damaged. Do not press or

scratch the surface harder than a HB pencil lead.

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

staining and discoloration may occur.

(e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft

cloth.

(f) The 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.

(g) 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 thoroughly with soap.
(h) Protect the module from static , it may cause damage to the CMOS Gate Array IC.
(i) Use finger-stalls with soft gloves in order to keep display clean during the incoming

inspection and assembly process.

(j) Protection film for polarizer on the module shall be slowly peeled off just before use

so that the electrostatic charge can be minimized.
(j) Pins of I/F connector shall not be touched directly with bare hands.

(1) The storage room should provide good ventilation and temperature control.
(2) Products should not be placed on the floor, but on the Pallet away from a wall.
(3) Prevent products from direct sunlight, moisture nor water; Be cautious of a

build up of condensation.

(4) Avoid other hazardous environment while storing goods.
(5) If products delivered or kept in conditions of the recommended temperature

or humidity, we recommend you leave them at a circumstances which is
shown in the following table.

10.3 Operation
(a) Do not connect,disconnect the module in the "Power On" condition.
(b) Power supply should always be turned on/off by the item 6.3 "Power on/off sequence"
(c) Module has high frequency circuits. Sufficient suppression to the electromagnetic

interference shall 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 inverter power supply shall be a

minimized length and be connected directly. The longer cable between the back-light and
the inverter/converter may cause lower luminance of CCFL/LED and may require higher
startup voltage(Vs).

10.4 Operation Condition Guide

(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. ( the 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 displays the same pattern continuously for a long period of time, it can be

the situation when the image "Sticks" to the screen.

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

order not to be stressed.
