We had the chance to talk with Dan Orr, who’s the product line supervisor and technique director for Corning Gorilla Glass. We requested in regards to the 7i glass that was introduced right now, but in addition total tendencies within the trade.
Earlier this 12 months Samsung launched the Galaxy S24 Extremely – amongst its many spotlight options is Gorilla Glass Armor, generally known as simply “Gorilla Armor”. What makes it particular is the anti-reflective coating, which reduces reflectance by as much as 75%, which boosts readability.
Orr says that sturdiness remains to be necessary, however now the optical properties of the glass are in focus too. Armor reduces reflections, improves gentle transmittance (and with that out of doors readability too), plus coloration rendering.
Trendy OLED shows are technological wonders – we’re seeing panels that may push out 4,000-5,000 nits. That is one option to struggle glare and enhance readability exterior, nevertheless it comes at a value. Lithium battery tech has not saved up with OLED growth and people excessive brightness ranges definitely put a pressure on the battery.
With glass like Armor, the show can run at a decrease brightness, whereas nonetheless reaching the identical readability for the top consumer. And for those who occur to seek out your self at a seashore on the equator at midday, then the cellphone nonetheless has the choice to crank up the brightness. However for many conditions, this shouldn’t be crucial.
Gorilla Armor (and comparable glasses) will grow to be extra well-liked sooner or later, however for now, at the least, the Galaxy S24 Extremely has exclusivity.
Armor pulls from a number of branches of the Gorilla household – Victus, after all, but in addition issues like Gorilla Glass DX and DX+. DX was launched a number of years in the past to be used as glass cowl above smartphone cameras – it lowered the glare cameras undergo when pointed at shiny gentle sources.
Nevertheless, combining the varied issues was not straightforward – the particular coating utilized by Armor can’t simply be utilized to any glass, at the least not with good outcomes. Corning designed the glass and the coating to work collectively – the ultimate end result has the improved sturdiness and scratch resistance that we anticipate with the brand new enhanced optical qualities.
Circling again to Gorilla Glass 7i, it’s meant to fill the hole between Gorilla Glass 5 and the Victus collection. There are already a number of mid-rangers with Victus, Victus+ and even Victus 2, so it’s not unique to flagships. Nevertheless, not all telephones can match it inside their budgets.
GG5, in the meantime, is a glass that launched in 2016, eight years in the past. And it’s nonetheless in energetic use even in 2024, with telephones just like the Nothing Cellphone (2a), Poco F6 Professional and others. Taking a look at final 12 months, there are much more – Poco F5, Xiaomi 13T, Galaxy A34. Some flagship gadgets used it for his or her again covers, e.g. the OnePlus 11 and Oppo Discover X5 Professional.
However these are telephones with 6.7” to six.8” shows (and the again is identical dimension), whereas the common display dimension in 2016 was simply 5.3”. Because of this GG5 was designed for a world the place telephones have been a lot smaller – and far lighter too. Trendy telephones are heavier partly resulting from their bigger dimension and likewise due to their bigger batteries. The inner construction of telephones has modified too, since bigger gadgets are simpler to bend and flex, makers needed to make them stiffer and extra sturdy (and that provides extra weight).
The common cellphone weight in 2016 was 156g. Taking a look at some trendy examples, the Galaxy S24 is 167g, the Zenfone 10 is 172g and the Pixel 8a 188g. And these are what go for “small” telephones lately, the 6.7+ inch fashions are sometimes over 200g. Bigger glass is extra susceptible. Heavier telephones make for stronger impacts. The mathematics doesn’t look good.
Gorilla Glass 7i is a seventh technology glass and it’s extra sturdy than its predecessors. Corning claims that it’s more durable than competing glasses on this section too – able to surviving drops onto asphalt from 1m (3.3ft) top, twice the peak that may crack competing glasses. And 7i is alleged to have double the scratch resistance of these glasses too.
We’d prefer to thank Dan Orr and the crew at Corning for speaking to us about what’s been occurring with smartphone glass and what’s but to come back.
