Packaging and Transportation of LCD Displays

Due to the delicate nature of LCD displays as precision electronic products, their transportation requires special attention to environmental factors such as electromagnetic fields, electrostatic discharge, road conditions, transportation vehicles, and weather. These factors can potentially cause damage to the LCD screen during transit, rendering them unusable and increasing transportation costs. Therefore, protective packaging during transportation is of paramount importance. Here are several technical requirements for cushioning packaging during the transportation of LCD :

The external packaging should bear the manufacturer's name, product model, and transportation markings such as "Handle with Care," "Moisture Sensitive," and "This Side Up," complying with the regulations of GB191. Other product labels should also comply with relevant national regulations.
The markings or labels on the packaging must not fade, discolor, or peel off due to transportation or environmental conditions.

Packaging Box Requirements:
The packaging boxes should meet the requirements for moisture resistance, dust proofing, and shock absorption. Inside the packaging box, there should be a packing list, inspection certificate, relevant accessories, and related documentation.
The packaged products should be capable of being transported via any mode of transportation to any location. During long-distance transportation, they must not be loaded in open cars or cabins. During intermediate transfers, they must not be stored in open-air warehouses. It is prohibited to transport products with flammable, explosive, or corrosive materials, and the products should be protected from rain, snow, or exposure to liquid substances and mechanical damage during transportation.

The products should be stored in their packaging boxes, and the warehouse environment should have a temperature range of 0°C to 40°C and relative humidity of 30% to 85%. The warehouse must not contain any harmful gases, flammable, explosive products, or corrosive chemicals. The warehouse should also be free from strong mechanical vibrations or impacts. The packaging boxes should be kept at least 100mm above the ground and at least 500mm away from walls, heat sources, cold sources, windows, or air inlets. Unless otherwise specified, the storage period should generally be six months. If the products are stored at the manufacturing plant for more than six months, a reinspection should be conducted before delivery.

◆For long-term storage (several years) due to certain reasons, we recommend the following approach:

◆Place the product in a polyethylene bag (preferably with an antistatic coating) and seal the bag.
◆Store the product in a dark place to avoid exposure to strong light.
◆Do not place any objects on the surface of the product.
◆Strictly avoid storing the product in environments that exceed the limits of temperature and humidity.

The transportation environment refers to all the stages from the factory to the hands of the customers, including loading and unloading on vehicles, stacking in warehouses, etc. Each stage subjects the product to different forces, leading to various responses, vibrations, or impacts. In cushioning and shock absorption design, the emphasis varies depending on different transportation stages. For example, for products with frequent loading and unloading, the design focuses on impact resistance. On the other hand, for long-distance transportation with fewer loading and unloading cycles, the design considers the resonance problem during stacking. Studies have shown that there are significant periodic excitation forces present during train transportation, and improper design may cause resonance and significant damage to the products. The same applies to products transported on trucks, especially those placed at the rear of the vehicle, as they may experience resonance during transportation, leading to product damage.

It is essential to consider three major damage factors - impact, resonance, and fatigue - in transportation environment design. However, the emphasis may vary for different transportation stages. If conditions permit, the transportation environment should also be taken into account since packaging materials, mainly composed of cardboard boxes or plastic films, may undergo changes in performance due to temperature, wind, rain, etc.
