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

Backlight(Recommended)
Attention:
(1) The supply voltage of the external system for the open cell input should follow the definition of VCC.
(2) When the customer’s backlight turns on before the LCD operation or the LCD turns off before the backlight turns off, the
display may momentarily become abnormal screen.
(3) In case that VCC is in off level, please keep the level of input signals on the low or high impedance. If T2 < 0, that may
cause electrical overstress.
(4) T4 should be measured after the module has been fully discharged between power off and on period.
(5) Interface signal shall not be kept at high impedance when the power is on.

6.1 Measurement Conditions
The table below is the test condition of optical measurement.
To avoid abrupt temperature change during optical measurement, it’s suggested to warm up the LCD module more than 45
minutes after lighting the backlight and in the windless environment.
To measure the LCD cell, it is suggested to set up the standard measurement system as Fig. 6.1. The measuring area S
ST2751A01-4 Product Specification
should contain at least 500 pixels of the LCD cell as illustrated in Fig.6.2 (A means the area allocated to one pixel). In this
model, for example, the minimum measuring distance Z is 370 mm when is 2 degree. Hence, 500 mm is the typical
measuring distance. This measuring condition is referred to 301-2H of VESA FPDM 2.0 about viewing distance, angle, and
angular field of view definition.

6.2 Optical Specifications
The table below of optical characteristics is measured by MINOLTA CS2000, MINOLTA CA310, ELDIM OPTI
Scope-SA and ELDIM EZ Contrast in dark room.（The optical data in the form is measured by matching the Backlight of
MT2751A01-1.）
Note:
(1) Definition of static contrast ratio (CR):
It’s necessary to switch off all the dynamic and dimming function when measuring the static contrast ratio.
Static Contrast Ratio (CR) =
CR-W is the luminance measured by LMD (light-measuring device) at the center point of the LCD module with
full-screen displaying white. The standard setup of measurement is illustrated in Fig. 6.3 ; CR-D is the luminance measured
by LMD at the center point of the LCD module with full-screen displaying black. The LMD in this item is CS2000.
(2) The LMD in the item could be a spectroradiometer such as (KONICA MINOLTA) CS2000, CS1000(TOPCON), SR-UL2
or the same level spectroradiometer. Other display color analyzer (KONICA MINOLTA) CA210, CA310 or (TOPCON)
BM-7 could be involved after being calibrated with a spectroradiometer on each stage of a product.

9. Precautions
9.1 Assembly and Handling Precautions
(1) Do not apply rough force such as bending or twisting to the open cell during assembly.
(2) It is recommended to assemble or install a open cell into the user’s system in clean working areas. The dust and
oil may cause electrical short or damage the polarizer.
(3) Do not apply pressure or impulse to the open cell to prevent the damage to the open cell.
(4) Always follow the correct power-on sequence. This can prevent the damage and latch-up to the LSI chips.
(5) Do not plug in or pull out the interface connector while the open cell is in operation.
(6) Use soft dry cloth without chemicals for cleaning because the surface of polarizer is very soft and easily be
scratched.
(7) Moisture can easily penetrate into the open cell and may cause the damage during operation.
(8) High temperature or humidity may deteriorate the performance of the open cell. Please store open cell in the
specified storage conditions.
(9) When ambient temperature is lower than 10 ºC, the display quality might be deteriorated. For example, the
response time will become slow.
9.2 Safety Precautions
(1) 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, skin or clothes, it has to be washed away thoroughly with soap.
(2) After the open cell end of life, it is not harmful in case of normal operation and storage.
