The application of foam material in LCD liquid crystal display

LCD is the abbreviation of Liquid Crystal Display, the structure of LCD is a liquid crystal placed in the middle of two pieces of parallel glass, and there are many tiny vertical and horizontal wires in the middle of the two pieces of glass, which control the direction of the rod-like crystal molecules by energizing or not, and refract the light to produce the picture. It is much better than CRT, but more expensive. Now LCD has replaced CRT as the mainstream, the price has also dropped a lot, and has become fully popular.

As an electronic product, LCD liquid crystal display in daily use is easy to contact with sweat, accidentally will also encounter tea. These situations are increasingly stringent requirements for the waterproof sealing of electronic devices.

Rogers waterproof sealing foam is made by adding water-repellent raw materials to polyurethane to produce a polyurethane foam that meets the requirements of compressibility and good thickness retention while providing excellent waterproof sealing effects. It can help with the waterproofing problem of electronic equipment.

Advantages and application scope of foam materials in LCD

Advantage：

Flexibility to adapt to various environments
Flexibility allows for protective sealing with only a little pressure
High compressibility allows the material to fit into different gap widths, resulting in greater design flexibility
Reduced maintenance costs associated with gasket failure due to compression deformation and softening
Excellent waterproof sealing performance

Features:

A wide range of thicknesses, 0.10 to 4.00mm provides options for a variety of spaces to be filled
Good sealing performance, under the right amount of compression, can provide a good dust-sealing effect for equipment
Long-lasting elasticity, providing long-lasting and stable positioning for the parts to be fixed
Super soft and compressible, with up to 90% compression
Tough surface, easy to match with protective film, not easy to drop
Good shock absorption performance, can effectively protect the components and reduce the impact damage
Excellent resistance to compression deformation, providing long-term protection for the device

Application areas:

Polyurethane foam is widely used for cushioning in cell phones and laptops, electronic devices, as well as in the interiors of aerospace and rail vehicles. Urethane foam has excellent resilience, good vibration and impact absorption, and an excellent waterproof sealing effect. Its wide range of hardness and thickness options and ease of compression makes it suitable for applications requiring high flexibility.

Applications Scope:

Cell phone speakers, power modules, lampshade sealing, automotive, electronic equipment, and computer communication equipment industries

Electronics, cameras, speakers, LCDs, signage, etc. fixed bonding and protection

Battery, plug compression foam

Computer, and electronic equipment, such as foot pads
