General Description
Description
LTI400HA01 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 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, Display terminals for AV application products, and Digital Information Display (DID).
Features
RoHS compliance (Pb-free)
High contrast ratio, High aperture ratio
SPVA(Super Patterned Vertical Align) mode

2. Application information for DID (Digital Information Display)
A long-term display like DID application may cause uneven display including image retention.
To optimize module's lifetime and function, several operating usages are required.
1. Normal operating condition
- Temperature: 20 ± 15℃
- Humidity: 65 ± 20 %
- Display pattern: moving picture or regular switchover display
Note) Long-term static information image may cause uneven display.
2. Operating usages under abnormal operating condition. Note (1)
a. Ambient condition
- Well-ventilated place is recommended to set up DID system.
b. Power off and screen saver
- Periodical power-off or screen saver is needed after long-term static display. Note (2)
3. Operating usages to protect uneven display due to long-term static information display
a. Suitable operating time for B-DID : under 12 hours a day.
b. Periodical display contents change from static image to moving picture.
- Liquid crystal refresh time is required.
c. Periodical background color and character (image) color change
- Use different colors for background and character (image), respectively.
- Change colors periodically.
d. Avoid combination of background and character with large different luminance.
Note (1) Abnormal condition means every operating condition except normal operating condition.
Note (2) Moving picture or black pattern is strongly recommended for screen saver.
4. Lifetime in this spec is guaranteed only when DID is used under right operating usages.

Note (1) Test Equipment Setup
The measurement should be executed in a stable, windless and dark room between
40min and 60min after lighting the backlight at the given temperature for stabilization
of the backlight. This should be measured in the center of screen.

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 V

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
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 CCFT 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 static, or the CMOS Gate Array IC 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 pull or fold the lamp wire.
(m) Do not adjust the variable resistor located on the Module.
(n) Protection film for polarizer on the Module should be slowly peeled off just before use
so that the electrostatic charge can be minimized.
(o) Pins of I/F connector should not be touched directly with bare hands.

10.2 Storage
(a) Do not leave the Module in high temperature, and high humidity for a long time.
It is highly recommended to store the Module with temperature from 0 to 35℃
and relative humidity of less than 70%.
(b) Do not store the TFT- L CD Module in direct sunlight.
(c) The Module should be stored in a dark place. It is prohibited to apply sunlight or
fluorescent light in storing.
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 inverter power supply should
be connected directly with a minimized length. A longer cable between
the back light and the inverter may cause lower luminance of lamp(CCFT) 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. O therwise, 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) Module should be turned clockwise (regular front view perspective) when used in
portrait mode
(c) Avoid condensation of water. It may result in improper operation or disconnection
of electrode.
(d) 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.
(e) 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.
(f) This Module has its circuitry PCB's on the rear side and should be handled
carefully in order not to be stressed.
(g) Please contact SEC in advance when you display the same pattern for a long time.
