The old generation smartphone display screen was highly criticized about its durability and flexibility when pressured is applied. In reaction to the related issue, screen protectors were customized into mobile size devices and was patronized as an accessory which can help lessen the impact of damage or wear and tear of your display screen when smartphone and tablet market grew and appeared to be a replacement for conventional laptops.

The history of screen protectors came from laptop device generations in which almost all computer shops were selling different brands to supply the growing market demand of laptop screen protectors as people were fanatical about taking good care of their valuable laptops.

In 2010, many manufacturers like Sony had started to introduce scratch resistant glass on their first generation smartphones which attracted many customers to buy one. In this instance, Sony was trying to resolve the issue of display screen problems such as unnoticed scratches on highly usage of touch screen devices. Then the following months or so, Samsung decided feature Gorilla Glass display technology. In this sense, primary materials properties were modified through a higher scratch resistance and improvement on durability display by increasing protective coating with a rating of 622-701.

Around October 2012, Gorilla Glass 2 was finally introduced as the second generation from its Gorilla Glass family which featured a 20% thinner glass display from the first generation through corning process. It was known as Corning Gorilla Glass. Samsung was also the first one to use this type of technology in their Smartphone series like Galaxy S3, S4 and other high end models.

By the start of 2013, third generation of Gorilla Glass display, featured in a Computer Electronic Show, known as Willow Glass incorporates Native Damage Resistance with 40% scratch resistance protection. This type of display screen technology has 3 times higher scratch resistance from the previous and more flexible one to avoid hard breaking.

Scientifically, Gorilla Glass is hardened through an ion exchange process. The material is said to be drowned in a certain chemical known as potassium salt which is molten at high temperature of 400 °C to give a higher level of compression stress. Thereby, enhancing the scratch resistant rates for even higher pressure.
