Description

LTA320AP11 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 and High Definition TV

Features

 High contrast ratio & aperture ratio with wide color gamut
 APVA (Advanced Patterned Vertical Align) mode
 Wide viewing angle (±178°)
 High speed response
 HD resolution (16:9)
 Low Power consumption
 U-Type 4 CCFLs (Cold Cathode Fluorescent Lamp)
 DE (Data Enable) mode
 1ch LVDS (Low Voltage Differential Signaling) interface (1pixel/clock)

Note) Power Consumption is measured when 500[cd/m2] of luminance which is the typical luminance.

Lamp Current is measured at the point before Lamp.
(1) Max Value of the Power Consumption is measured during initial turn-on time* of the backlight.
(2) Max Value of the Power Consumption is measured after 120 min warm-up.
(3) Inverter pin NO.12 is for backlight On/Off.
(4) Inverter pin NO.13 is for dimming control.

* Initial turn-on time : From 0sec to 60min after turn-on

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 V

DD

.

 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

DD

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 )

9. General Precautions

Samsung Secret

9.1 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 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
handling a module

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

9.2 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.

9.3 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).

9.4 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. Other wise, its reliability and
function may not be guaranteed. Extreme conditions are commonly found at
Airports, Transit Stations, Banks, Stock market, and Controlling systems.

9.5 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.
