Hello!! It's Joseph

Huawei has named the folding phone’s structure “Falcon Wing”(鷹翼式) and its specialists have been taking a shot at this plan for a long time. When you crease the cell phone, there are no holes between the cell phone’s front and the back. Huawei says there are more than 100 parts on the cell phone’s pivot, which it has licensed. For Huawei, each pixel size is roughly 0.05 mm or 50 microns or 414 ppi 采取四层结构设计，最上面一层是高分子材料的屏幕保护层，第二层是可弯曲的柔性屏幕，第三层是软胶支撑片，最下面一层是转轴。 转轴的重要性和难点在于，屏幕和转轴是一个耦合关系，涉及到复杂的运动原理。在屏幕硬件长度不变的情况下，手机弯折和伸展的过程中，HUAWEI Mate X需要通过转轴结构的自动伸缩，实现对0-180度开合状态下的屏幕进行同步、精准、连续的支撑。 在每一个角度下，转轴的部件都要基于运动原理沿着一个导轨运动，并精准伸出对应的长度，来配合屏幕的位移和受力。如果出现运动误差，屏幕就会在挤压和伸展时受到损伤，进而影响手机的使用寿命。 Samsung Galaxy Fold: The  bend radius in Samsung Fold is ~ 1.5mm. Whereas 4.4 mm bend radius in Moto Razr V4. Conclusion: When folded( ie when phone is not in use), Huawei's screen is stretched. Samsung's is not. Samsung's better The stre

If the GDP growth of both regions is somewhat co-related, Q4 18 to Q3 19, China's GDP has been  contracting for 0.6 %(from 6.8 to 6.2 %). In the same time frame, HK's GDP has contracted for 6.3% ( 3.4% to - 2.9%) percentage change normalised to Q4 16 figures “The Hong Kong economy saw an abrupt deterioration in the third quarter of 2019, as the - local social incidents dealt a very severe blow to an economy already weakened by - a synchronised global economic slowdown and - US-Mainland trade tensions,” said Hong Kong Government Economist Andrew Au. Four key industries: The major declines are gross domestic fixed capital formation and exports of goods Gross domestic fixed capital formation covers the gross value of expenditure on building and construction as well as machinery, equipment and intellectual property products(including computer software, databases and research and development); and costs of ownership transfer.
