In the evening of August 4, Beijing time, IDC released a report today that the global AR (Augmented Reality) and VR (Virtual Reality) market spending will reach 11.4 billion U.S. dollars this year, and in 2021 it will increase to 215 billion U.S. dollars.
According to the report, global AR/VR product and service spending will increase from 11.4 billion U.S. dollars this year to 215 billion U.S. dollars in 2021, with a compound annual growth rate (CAGR) of 113.2%.
Among them, the United States has the highest AR/VR spending and will reach US$3.2 billion this year. The Asia-Pacific region (excluding Japan) will follow closely, spending will reach 3 billion U.S. dollars. In Western Europe, spending will reach 2 billion U.S. dollars. In the next two years, the AR/VR spending in the Asia-Pacific region will surpass that of the United States, but in 2020, the United States will return to the top.
This year, the consumer sector will become the largest source of AR/VR revenue. In the United States and Western Europe, the second largest source is discrete manufacturing and process manufacturing. In the Asia-Pacific region, the second largest source is the retail and education industry.
The report also stated that this year and next year, the spending of VR systems including heads-up, software, consulting services, and system integration services will be greater than AR-related expenses. After 2018, AR spending will increase significantly. (Li Ming)
Semiconductor Fuse And Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
