x 1200 and this model can display up to 16.7 millions colors.

Features

 High contrast ratio, high aperture structure, High Color Gamut
 TN (Twisted Nematic) mode
 Wide Viewing Angle
 High speed response
 Wide UXGA (1920 x 1200 pixels) resolution
 Low power consumption
 DE (Data Enable) only mode
 LVDS (Low Voltage Differential Signaling) interface (2pixel/clock)
 Direct B/L Unit Design
 RoHS compliance
 Pb Free compliance

(2) Lamp frequency which may produce interference with horizontal synchronous
frequency may cause line flow on the display. Therefore lamp frequency should be
detached from the horizontal synchronous frequency and its harmonics as far as
possible in order to avoid interference.

50% or less than its original value at the condition of Ta = 25·2¶C and I

(4) Designing a system inverter intended to have better display performance, power
efficiency and lamp reliability.

They would help increase the lamp lifetime and reduce leakage current.

a. The measurement should be done at typical lamp current.
b. The asymmetry rate of the inverter waveform should be less than 10%.
c. The distortion rate of the waveform should be √2 with ±10% tolerance.

- Inverter output waveform had better be more similar to ideal sine wave.

Product Information

8.2 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.

8.3 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 item 6.3

"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).

8.4 Oper

(a) The LCD product should be operated under normal conditions.

ation Condition Guide

Normal condition is defined as below;

- Temperature : 20·15୅

- Humidity : 65·20%

- 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.
