Absolute Maximum Ratings

Note:

1. This rating applies to all parts of the module. And should not be exceeded.

2. The operating temperature only guarantees operation of the circuit. The contrast, response speed, and the other specification related to electro-optical display quality is determined at the room temperature, TOP=25°C.

3. Ambient temperature when the backlight is lit (reference value).

4. Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.

5. (a) 95% RH Max. (Ta <= 40 °C).
   (b) Wet-bulb temperature should be 39 °C Max. (Ta > 40 °C).
   (c) No condensation.

6. The temperature of panel surface should be 0 °C min. and 60 °C max.

LCD Module Design and Handling Precautions

• 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 C~40 C <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.
• 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 pattern. 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.

Rear Mounting with Frame

• Application panel opening:The suggested assemble gap(A) should be about 0.3~0.5mm on each side.
• Install the TFT module on strong flat surface for installation and sealing.

Rack Mount Installation

• Support rack mount 75x75mm VESA or 100x100mm VESA.
• BxM4(5mm(d)) back side mounting holes.
• Select rack which can hold >10kg device.
• Please ensure rack fixture before mount on the device.
