1.2 Overview
MT2751A01-1 Product Specification
MT2751A01-1 is a diagonal 27 .5” color active matrix LCD module with edge LED backlight and 1ch-LVDS interface.
This module is a transmissive type display operating in the normally black mode. It supports 1366 x 768 HD resolution and
can display up to 16.7M colors (8-bit). Each pixel is divided into Red, Green and Blue sub-pixels which are arranged in
horizontal stripe. The converter of backlight is built-in.
This module dedicates for LCD TV products and provides excellent performance which includes high contrast ratio, ultra
wide viewing angle, low power consumption and high color depth.

2.1 Absolute Maximum Ratings (TA = 25 ± 2 °C)
The followings are maximum values which, if exceeded, may cause damage to the unit.
2.2 Environment Requirement
(1) Temperature and relative humidity range are shown as below.
MT2751A01-1 Product Specification
Fig. 2.1 Operating and storage environment
(a) 90%RH maximum (TA < 39 ºC).
(b) Wet-bulb temperature should be 39 ºC maximum (TA > 39 ºC).
(c) No condensation.
(2) The storage temperature is between - 20 ºC to 60 ºC , and the operating ambient temperature is between 0 ºC to 50 ºC .
The maximum operating temperature is based on the test condition that the surface temperature of display area is less than
or equal to 65 ºC with LCD module in a temperature controlled chamber alone. Thermal management should be considered
in final product design to prevent the surface temperature of display area from being over 65 ºC. The range of operating
temperature may degrade in case of improper thermal management in the end product design.
(3) The TFT module including glass should be avoided any shock or vibration.
While testing shock and vibration, the fixture holding the module should be assured to be hard and rigid enough to prevent
the module twisted or bent by the fixture. The test conditions should be less than:

MT2751A01-1 Product Specification
Shock (Non-operating): 35 G, 11 ms, half sine wave, 1 time for ± X, ± Y, ± Z.
Vibration (Non-operating): Random 1.0 Grms, 10 ~ 200 Hz, 10 min, 1 time for each X, Y, Z.
2.3 Package Storage
When storing modules as spares for a long time, please follow the precaution instructions:
(1) Do not store the module in high temperature and high humidity for a long time. It is highly recommended to store the
module with temperature from 0 ºC to 35 ºC in normal humidity.
(2) The module shall be stored in a dark area and avoided to be exposed in direct sunlight or fluorescent light.
