(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.

Optoelectronics Technology Co., Ltd.
MT4761B01-1 Product Specification
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:
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.

(3) Apply the lightbar voltage within the LCD operation range. When the backlight turns on before the LCD operation or the
LCD turns off before the backlight turns off, the display may momentarily become abnormal screen.
(4) 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.
(5) T4 should be measured after the module has been fully discharged between power off and on period.

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 module, it is suggested to set up the standard measurement system as Fig. 7.1. The measuring area S
should contain at least 500 pixels of the LCD module as illustrated in Fig. 7.2 (A means the area allocated to one pixel). In this
model, for example, the minimum measuring distance Z is 370 mm when θ 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

Precautions
9.1 Assembly and Handling Precautions
(1) Do not apply rough force such as bending or twisting to the LCD module during assembly.
(2) It is recommended to assemble or install a LCD module 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 LCD module to prevent the damage to LCD panel and backlight.
(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 module is in operation.
(6) Do not disassemble the LCD module.
(7) Use soft dry cloth without chemicals for cleaning because the surface of polarizer is very soft and easily be scratched.
(8) Moisture can easily penetrate into the LCD module and may cause the damage during operation.
(9) High temperature or humidity may deteriorate the performance of the LCD module. Please store LCD modules in the
specified storage conditions.
MT4761B01-1 Product Specification
(10)When ambient temperature is lower than 10ºC, the display quality might be deteriorated. For example, the response
time will become slow, and the starting voltage of LED light bar will be higher than that in room temperature.
