How to Incorporate Shock Absorption Into Your Existing Assembly

How to Incorporate Shock Absorption Into Your Existing Assembly

Oct 15th 2021


Displays surround us everywhere in our day-to-day lives, showing up throughout our day in innovative new ways all of the time. With the growing world of devices using LCD screens, it is important to protect them. Portable and handheld devices are the most susceptible to accidental dropping and breaking. This, in turn, means they will need to be replaced more often.

LCD screens can be protected from damage by adding shock absorption into the casing or assembly of the LCD screen. Also, shock-absorbing screen protectors can be added to the screen itself for added protection and place the whole screen into a case.

What is Shock Absorption and Why Do I Need It?

Shock absorption can be explained as an adjunct material - like rubber or silicone - intended to provide extra cushioning for mechanical shocks, such as those caused by dropping something on your screen with nothing protecting it. When you experience this type of impact force, your LCD will quickly stop moving while continuing its function simultaneously, which could cause scratches on the surface and cracks that go all across from one side to another.

Mechanical shock absorbers reduce vibration and motion by converting energy into heat or sound waves that dissipate quickly, lowering the chance of damage. This is beneficial when devices are moved around often, such as small monitors, tablets, and handhelds. 

How Shock Absorption Can Help LCDs

LCD screens are fragile, and that must be taken into consideration when handling them. Shock absorption will help prevent LCD screens from being damaged by sudden changes in movement or vibration. There are a few different ways to incorporate shock absorption into your assembly processes, such as using foam strips between the LCD screen and case, using a shock absorbent material the product enclosure, reducing weight of the device and adding a screen protector or protective layer over the face of the display.

Shock Absorbing Screen Protectors

Shock absorbers can also be added to the screen itself.

  • Shock absorbing screen protectors are a thin plastic cover that goes over the screen and absorbs impact, which reduces damage to both LCD screens.
  • These are usually clear or come in different colors, but they do not obstruct the visibility of LCD screens or affect touch sensitivity.
  • For these protectors, you can use either adhesive film with release paper backing (these often leave residue) or reusable static cling films, which work best for curved surfaces such as corners.

Shock Absorbing Cases

While shock absorption can be built-in into the assembly itself, you can also incorporate shock absorption into the case of LCD screens.

  • Cases are usually made from hard plastics, silicone, or rubber, and each material has different properties that help reduce impact.
  • Examples include a flexible polyurethane layer for padding against impacts in corner areas, with an air pocket to absorb pressure on sensitive parts like LCD screens. 

Shock Absorption Techniques: How Not to Break LCDs

If you want maximum protection for LCD screens while reducing damage caused by drops, shocks, and vibration, there are several techniques you can use to incorporate shock absorption.

  • Consider your LCD screens’ environment and choose the right materials for that type of use, such as rubber or silicone.
  • Another technique involves choosing a case with an air pocket in corners where it absorbs impact pressure on LCD screens from jarring movements. 

Conclusion

LCD screens are fragile and need protection from the elements and physical damage. Thankfully, integrating shock-resistant measures into your manufacturing process is far simpler than you may have thought.

Adding shock absorption in the LCDs assembly or adding shock-preventing cases and screen protectors is a great way to ensure your screen works well for years to come.
