Test Conditions:

1. I_VLED= 60mA, VLED=9.0V, and the ambient temperature is 25. ℃
2. The test systems refer to Note 1 and Note 2.

Note 1:

The data are measured after LEDs are turned on for 5 minutes. LCM displays full white. The brightness is the average value of 9 measured spots. Measurement equipment SR-3A (1°)

Measuring condition:

• Measuring surroundings: Darkroom
• Measuring temperature: Ta=25℃.
• Adjust the operating voltage to get optimum contrast at the center of the display

Note 2:

The definition of viewing angle:
Refer to the graph below marked by θ and Ф

Note 3:

The definition of contrast ratio (Test LCM using SR-3A (1°)):

Note 4:

Definition of Response time. (Test LCD using BM-7A(2°)):

The output signals of photo detector are measured when the input signals are changed from “black” to “white”(falling time) and from “white” to “black”(rising time), respectively. The response time is defined as the time interval between the 10% and 90% of amplitudes.Refer to figure as below .

Note 5:

Definition of Color of CIE1931 Coordinate and NTSC Ratio

Note 6:

The luminance uniformity is calculated by using following formula.

Note 7:

Measured the luminance of white state at center point

Warranty

LCD Module Design and Handling Precaution

• Please ensure V0, VCOM is adjustable, to enable LCD module get the best contrast ratio under different temperatures, view angles and positions.

• Normally display quality should be judged under the best contrast ratio within viewable area. Unexpected display pattern may com out under abnormal contrast ratio.
  Never operate the LCD module exceed the absolute maximum ratings.

• Never apply signal to the LCD module without power supply. （No Hot-plugging）

• WARNING! Be aware of (if any) frame grounding of the LCD Module connection with the system which may cause safety issue(e.g. electric shock,etc).

• Keep signal line as short as possible to reduce external noise interference.

• IC chip (e.g. TAB or COG) is sensitive to light. Strong light might cause malfunction. Light sealing structure casing is recommended.

• Make sure there is enough space (with cushion) between case and LCD panel, to prevent external force passed on to the panel; otherwise that may cause damage to the LCD and degrade its display result.

• Avoid showing a display pattern on screen for a long time (continuous ON segment).

• LCD module reliability may be reduced by temperature shock.

• When storing and operating LCD module, avoids exposure to direct sunlight, high humidity, high or low temperature. They may damage or degrade the LCD module.

• Never leave LCD module in extreme condition (max./min storage/operate temperature) for more than 48hr.

• Recommend LCD module storage conditions is 0℃~40℃ <80%RH.

• LCD module should be stored in the room without acid, alkali and harmful gas.

• Avoid dropping & violent shocking during transportation, and no excessive pressure press, moisture and sunlight.

• LCD module can be easily damaged by static electricity. Please maintain an optimum anti-static working environment to protect the LCD module. (eg. ground the soldering irons properly)

• Be sure to ground the body when handling LCD module.

• Only hold LCD module by its sides. Never hold LCD module by applying force on the heat seal or TAB.

• When soldering, control the temperature and duration avoid damaging the backlight guide or diffuser which might degrade the display result such as uneven display.

• Never let LCD module contact with corrosive liquids, which might cause damage to the backlight guide or the electric circuit of LCD module.

• Only clean LCD with a soft dry cloth, Isopropyl Alcohol or Ethyl Alcohol. Other solvents (e.g. water) may damage the LCD.

• Never add force to components of LCD module. It may cause invisible damage or degrade the module’s reliability.

• When mounting LCD module, please make sure it is free from twisting, warping and bending.

• Do not add excessive force on surface of LCD, which may cause the display color change abnormally.

• LCD panel is made with glass. Any mechanical shock (e.g. dropping from high place) will damage the LCD module.

• Protective film is attached on LCD screen. Be careful when peeling off this protective film, since static electricity may be generated.

• The polarizer on LCD gets scratched easily. If possible, do not remove LCD protective film until the last step of installation.

• When peeling off protective film from LCD, static charge may cause abnormal display patterns. The symptom is normal, and it will turn back to normal in a short while.

• LCD panel has sharp edges, please handle with care.

• Never attempt to disassemble or rework LCD module.

• If display panel is damaged and liquid crystal substance leaks out, be sure not to get any in your mouth, if the substance comes into contact with your skin or clothes promptly wash it off using soap and water.
