General Description

Samsung Secret

Description

LTA320XXXX 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 1920 x

1080 and this model can display up to 1.07G 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

 RoHS compliance (Pb-free)
 High contrast ratio, high aperture ratio, fast response time
 SPVA (Super Patterned Vertical Align) mode
 Wide viewing angle (±89°)
 Full HD (1920 x 1080 pixels) resolution (16:9)
 Low Power consumption
 WLED (White Light Emitting Diode) Backlight
 LVDS (Low Voltage Differential Signaling) interface

[Valid Data Condition]

1. Input LVDS signals must satisfy

“Interface Timing” Specification on p23.

2. LVDS Clock must keep the same frequency.

3. “Temp SEL” signal should be changed

within Tcon Reset and Tcon Ready.

4. Data signal should not input during

“Fail Safe Mode”.

 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.

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 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 LED FFC.
(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.

9.2 Storage

We highly recommend to comply with the criteria in the table below.

Item Unit Min. Max.

Storage

Temperature

Storage Humidity (%rH) 35 75

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 40

9.3 Operation

(a) No Connection 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 inverter may cause lower luminance of LED 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. Otherwise, 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.

Samsung Secret

(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.
