Adding DisplayPort to Type-C will make smartphones and VR / AR more fun

Release time: 2018-02-27 Clicks: 2212

Today's smart phones are increasingly using USB Type-C, but careful people may find that many of this Type-C cable can only transmit data and charge, and it does not yet support video transmission. Next, more and more smart phone, VR, AR equipment manufacturers will use Type-C as their standard interface, and integrate DisplayPort Alt Mode in it to achieve more powerful video output (Sources) and input (Sinks) functions.
According to Jim Choate, "USB-C supports USB 3.1 Gen 2 (10Gbps), power transmission up to 100W, and will also support DisplayPort Alternate Mode. In the next 20 years, USB Type-C will be an interface on electronic products, which is suitable for both Mobile products are also suitable for large electronics. "
Strategy Analytics analysis report pointed out that with the release of DisplayPort 1.4, DSC, FEC and MST functions have been added, and chips supporting HBR3 have been officially shipped. USB Type-C including DisplayPort Alt Mode will be welcomed by 2021. Peak shipment growth in the coming year, with a compound annual growth rate of 52%.
The shipment growth of smartphones is now gradually flattening. According to Strategy Analytics estimates, the compound annual growth from 2016 to 2021 is only 2%. In 2016, the proportion of USB Type-C mobile phones was only 6%, which is still large. Some Type-C interfaces can only implement charging and data transmission. But by 2021, shipments of Type-C smartphones will reach 156 million, with a growth rate of 57%.
In May last year, VESA organized a special interest group to focus on pro-VR / AR. This special interest group was established on the proposal of VESA member Silicon Valley Digital Analog Semiconductor, which is open to both VESA members and non-members. This interest group will work with other VESA task forces and related standards organizations to promote a strong ecosystem that benefits end users.
Jim Choate believes that USB Type-C with DisplayPort Alt Mode can simultaneously transmit two 4K ultra-high-definition images, which can well meet the requirement of displaying two channels of high-definition video on AV / VR devices at the same time, and currently has the support of many VR manufacturers. There are more than 260 AR / VR exhibitors at CES this year. One of the key issues that needs to be solved is how are these products compatible? It is also looking forward to all standards organizations working on AR / VR product functionality and interoperability issues. Now the VESA organization has set up a special interest group and decided to open it to non-members, which will help AR / VR products to be improved.
As the Qualcomm Snapdragon 835 platform supports DisplayPort Alt Mode, more mobile phones, VR / AR and other products on the market will support the popularity of 4K60 video. Type-C smartphones on the market no longer support fast charge and high-speed data transmission, but can realize the conversion between Type-C and HDMI 2.0B to support mobile phone output of 4K60Hz high dynamic range video, or use A single DisplayPort output drives two 4K60Hz displays.
In terms of the latest 8K display technology, Jim Choate said that the latest version of Display 1.4 can use VESA's Display Stream Compression (DSC) standard through a single cable to achieve 8K60Hz HDR dark applications.
The latest version of DSC (v1.2) developed by VESA can support consumer 8K display technology. VESA will showcase this version in 4K, displaying compressed and uncompressed video side by side to achieve better transmission flexibility.
VESA's Compliance Test Specification (CTS) was announced in December 2016. VESA members can conduct compliance tests on products through VESA's authorized testing centers around the world, or they can self-test and publish certified product information through the VESA database. Jim Choate believes that the CTS of the completed DisplayPort Alt Mode can achieve product reliability and predictability. For OEMs, DisplayPort Alt Mode can be integrated into the final design product, and consumers can rest assured that they have purchased a fully certified product without worrying about interoperability and compatibility issues.
Jim showed various Type-C to other interface adapters at the scene. It seems that in the future, although there is only one USB Type-C on a computer, TV or mobile phone, considering the different interfaces of various past products, the conversion connector between these various interfaces will also have a long-term market. .

Now Weizan has developed a variety of USB Type-C interfaces, a variety of pin positions, a variety of sizes, sincerely invite new and old customers to come to buy! !!
