1.2 Overview

ST2751A01-4 is a diagonal 27.5” color active matrix LCD open cell with 1ch-LVDS interface. This open cell 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. There is no backlight built-in.

This open cell dedicates for LCD TV products and provides excellent performance which includes high transmittance,

ultra wide viewing angle and high color depth. CSOT open cell comply with ROHS for identification.

2. Absolute Maximum Ratings

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 (Based on CSOT Module MT2751A01-1)

(1) Temperature and relative humidity range are shown as below.

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 rating of environment is based on LCD module. Leave LCD cell alone, this environment condition can’t be guaranteed.

Except LCD cell, the customer has to consider the ability of other parts of LCD module and LCD module process.

2.3 Absolute ratings of Environment (Open Cell)

When storing open cell 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 20 ºC to 30 ºC in normal humidity (50 ± 10%RH) with shipping package.

(2) The open cell should be keep within one month shelf life
