The liquid crystal display device panel used in the liquid crystal display module ismade of glass. Avoid any strong mechanical shock. If the glass should break,handle it with care.2. The polarizer on the surface of the LCD is relatively soft. Care must be taken toprevent scratches.2) Protection of liquid crystal display module against static electricity discharge1. When working with the module, be sure to ground your body and any electricalequipment you may be using. We strongly recommend using anti-static mats, toprotect worktables against the hazards of electrical shock.2. We recommend wearing a ESP grounding strap when handling the module.3. Slowly and carefully remove the protective film from the LCD module, since thiscan generate static electricity.3) When the LCD modules must be stored for long periods of time1. Protect the modules from high temperatures and humidity.2. Keep the modules away from direct sunlight or direct exposure to ultraviolet rays.4) Use the module with a power supply that is equipped with overcurrent protection since themodule does not employ current limiting protection circuitry.5) Do not ingest the LCD fluid if it should leak out of a damaged LCD module. If hands orclothing come in contact with the LCD fluid, wash immediately with soap and water.6) Conductivity is not guaranteed for models that use metal holders where solder connectionsbetween the metal holder and the PCB are not used. Please contact us to discussappropriate ways to assure conductivity.7) For models which use CCFL backlighting:1. CCFL backlights operate at voltage levels greater than 200 volts. Precautions mustbe taken to avoid electrical shock.2. Using CCFL backlighting for extended periods of time at low temperatures willsignificantly shorten their service life.8) For models which used touch panels:1. Do not stack modules because they can be damaged by components on neighboringmodules.2. Do not place heavy objects on top of the product because this can cause the glass tobreak.Ocular T035320240OSBF Module draft Specification Page 12 of 14

In order to maintain reliability, do not touch or hold by the connector area.2. Avoid bending, pulling, or any other excessive forces, which can result in brokenconnectors.Ocular T035320240OSBF Module draft Specification Page 13 of 14
