General Description
Description
LTA320W2-L14 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 32.0“ is
1366 x 768 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 High Definition TV (HDTV).
Features
ƒ RoHS compliance (Pb-free)
ƒ High contrast ratio, high aperture ratio, fast response time
ƒ APVA(Advanced Patterned Vertical Align) mode
ƒ Wide viewing angle ( 178 )
ƒ High speed response
ƒ WXGA (1366 x 768 pixels) resolution (16:9)
ƒ Low Power consumption
ƒ Direct Type 16 CCFTs(Cold Cathode Fluorescent Tube)
ƒ DE(Data Enable) mode
ƒ LVDS (Low Voltage Differential Signaling) interface (1pixel/clock)

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<T1 10msec
0<T2 50msec
0<T3 50msec
1000msec T4
1000msec T5
(Recommend Value)
100msec T6
(Recommend Value)
www.DataSheet4U.com
T1 : VDD rising time from 10% to 90%
T2 : The time from VDD to valid data at power ON.
T3 : The time from valid data off to VDD off at power Off.
T4 : VDD off 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.
ƒ The supply voltage of the external system for the Module input should be the same
as the definition of VDD.
ƒ 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.
ƒ In case of VDD = off level,
please keep the level of input signals low or keep a high impedance.
ƒ T4 should be measured after the Module has been fully discharged between power off
and on period.
ƒ Interface signal should not be kept at high impedance when the power is on.

10. Inspection Criteria
When products are shipped, incoming inspection should be carried out with a
sampling inspection based on MIL-STD-105E level II by AQL 1.0%.
CHANGE CONTROL
Design of the product may be changed regarding the specifications, appearance, parts
used, circuits, etc. for product improvement. If a design change is judged to affect the
specifications of this product, supplier should inform customer of the change in advance.
QUALITY CONTROL
In the event of a product failure under normal operating conditions, a product trouble
or a functional disorder that can be deemed to be the responsibility of supplier, supplier
should repair the fault or replace the product free of charge within one year from
the product delivery date. However, supplier does not take responsibility for the product
quality in the case of modifications not specified by supplier.
MAINTENANCE
The specifications of the functions of maintenance parts may be partially changed
within the range which provides equivalent or better quality.
In principle, maintenance parts should be product units.
When stopping manufacturing this product, supplier should notify customer in advance.
HANDLING OF DOUBTFUL POINTS
www.DataSheet4U.com
Any doubt not stipulated in this specification is to be resolved by mutual agreement
between customer and supplier, and supplier should make efforts for improvement
in good faith.

11. General Precautions
11.1 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.
www.DataSheet4U.com
(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.

11.2 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-LCD 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.
11.3 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).
11.4 Operation Condition Guide
www.DataSheet4U.com
(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.

11.5 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.
