The world's first all-aluminum mobile phone screen back panel
Recently, the CTO of JSDL Precision Aluminum Technology Corporation showed the Hay Think team "the world's first all-aluminum mobile phone screen backplane" and explained its characteristics:
First of all, the thickness of the mobile phone screen backplane is required to be 0.1 mm, but the current limit rolling thickness of hard aluminum alloy foils worldwide is 0.15 mm, and only JSDL can achieve 0.1 mm or even 0.05 mm;
Secondly, the backplane of the mobile phone screen needs to be pulled out with a 0.68 mm high front camera hole at a thickness of 0.1 mm, and the material itself is not deformed or cracked. JSDL has overcome this problem. "
Before this all-aluminum mobile phone screen back panel was born, the material of the mobile phone screen back panel was mostly stainless steel. "Compared with steel, aluminum is not only light in weight, good in heat dissipation, but also non-magnetic . The only drawback is that it is not strong enough. Therefore, in the past, the backplane of mobile phone screens could only be made of stainless steel.
The global aluminum industry giant UACJ developed hard aluminum alloy foil as early as more than a decade ago, which not only improved the hardness of the aluminum itself, but also improved the toughness, which also made the aluminum used as the screen backplane "become possible ". However, due to the limitation of the rolling thickness and material strength limit, the aluminum screen backplane was only used in notebook computers, pads, etc., and the mobile phone screen backplane can only be made of stainless steel.
Since JSDL successfully produced the "world's first" all-aluminum mobile phone screen back panel, it has become the largest supplier of the global semiconductor display product leader "BOE", and many well-known brands such as Acer, Asus, Huawei, Xiaomi … They are also its customers.
About JSDL
JSDL is committed to R&D and production of large aluminum and aluminum alloy plate, high-precision aluminum alloy plate, belt, foil and brazing aluminum alloy composite material.
JSDL is currently the only company in China that can localize display backplane materials. Since UACJ developed hard aluminum alloy foils and applied them to laptop and tablet screen backplanes, UACJ's supply channels have been firmly in the hands of UACJ.
In order to break this "UACJ monopoly" situation, JSDL has not only developed materials with the characteristics of Japanese hard aluminum alloy foils, but also upgraded and optimized them to reduce thickness and increase strength. At the beginning of 2018, JSDL high-performance special aluminum alloy began mass production, and in the same year it entered the list of suppliers of BOE, a leading global semiconductor display product company. At present, JSDL is BOE's largest supplier.
JSDL makes “there is no piece of laptop keyboard aluminum alloy bracket made by a Chinese company” as “the past tense”. In March 2019, JSDL’s laptop keyboard aluminum alloy bracket formed a batch order; JSDL developed an anodized notebook computer The high-strength aluminum alloy casing has passed the verification of many brand manufacturers… At present, the company supplies BOE, AUO, Acer, Asus, Huawei, Xiaomi, OPPO, Dell, Lenovo, TCL, Coolpad and many other well-known brands are also Its customers.
