Mobile information
Now many mobile phones have started to use the Type-Ch interface. Because it is more convenient to use, you don’t need to divide the front and back sides, and you can plug it in any way. However, some major manufacturers still use Mirco-USB and don’t use Type-C. Why is this?
Type-C VS Mirco-USB
Recently, OV released two new phones, OPPO R15 and vivo X21. In addition to the low-end and high-price as always, it is shocking that the traditional Mirco-USB interface is still used on the USB interface.
In recent years, Type-C has begun to be favored by the majority of manufacturers. Almost all flagships at high prices have adopted the Type-C interface. Compared with the traditional Mirco-USB, Type-Ch has obvious advantages.
Type-C has multiple versions of
Type-C, either version is OK, 2.0, 3.0, and 3.1 are all possible. Many mobile phones now have Type-C interfaces, but in fact it is just USB2.0, which is that trick. Specifically, the traditional USB3.0 name has been completely replaced. The current USB3.0 is called USB3.1, but USB3.1 itself is divided into two versions, gen1 and gen2. gen1 is 5Gbps (bps refers to the bit rate and the common unit of data transmission rate) 's bandwidth is completely equal to USB3.0, while gen2 is 0Gbps, which is the latest USB0Gbps.
TypeC can also carry video signals and thunder 3 (Intel. The long-promoted Light Peak technology, and named "Thunderbolt" (Thunderbolt) interface. Thunderbolt tml2 connection technology integrates PCIExpressdata transfer technology and DisplayPort display technology, which can be simultaneously The data and video signals are transmitted, and each channel provides bidirectional 0Gbps bandwidth. ). The previous lightning interface looks like Mini-DP (Mini-DP refers to a small interface of the DisplayPort interface, mostly used in superbooks) . It has become like this since Type-C came.
, but be sure to note that this is an optional option. does not mean that all Type-Ch can output video signals and support lightning.
What are the benefits of Type-C interface
supports front and back
insertion like Apple's Lightning (Apple released a brand new Lightning Dock interface, which can be translated as "lightning" interface in Chinese) interface, can be inserted with your eyes closed, truly realizing 100% " blind insertion " , and also improves the life of the interface.
transmission speed is fast
supports USB3.1 transmission protocol, and the theoretical maximum transmission rate can reach 10Gbps per second. Apple says the new MacBook's USB-Ch port maximum transmission rate is 5Gbps. The maximum output voltage of is 0 volt, which can speed up the charging time. , and USB-A, so far, have an extreme transmission rate of 5Gbps and an output voltage of 5V.
lighter and thinner
A thinner body requires a thinner port, and the size of the Type-C socket end is about 8.3mm×2.5mm; the old USB port is 1.4 cm long and 0.65 cm wide, it seems outdated. This also means that the end of the USB-C data cable will be one-third of the size of the standard USB-A data cable plug, which is one of the reasons why Type-C came into being.
has strong expansion functionality
Due to the many pins, Type-C has relatively strong expansion functionality, and can do audio and video signal transmission, high-power power supply, etc. Type-C is positioned as an all-round high-performance interface with charging, data transmission and audio-visual transmission functions.Therefore, the power interface, USB interface, signal interface ( DP interface, HDMI interface, VGA interface, etc.), can be carried by a Type-Ch interface, and a wire can replace a bunch of lines such as charging cables, signal transmission lines, etc., and will never become " Spider-Man " .
If you have a Type-C expansion dock, then can also expand N interfaces with one wire and one interface, such as HDMI, multiple USB, and even RJ45. This is something that the traditional USB interface cannot do.
Why is OV unwilling to replace Type-Ch
Since the Type-C interface has so many advantages, why is OV sticking to the previous set of standards?
because Type-C is expensive, so I am unwilling to replace it?
Some netizens think that the cost of Type-C is higher than that of traditional Mirco-USB. In order to save costs, save as much as possible, and the OV selection will not be changed. Some netizens think that compared with OVs that tend to make the body light and thin, adopting the Type-C interface will increase the thickness of the body. In addition, since OPPO uses VOOC flash charging technology, there are also obstacles in the implementation of technology. In the editor's opinion, these statements are untenable. In terms of cost saving, large blue and green manufacturers are already big manufacturers, and it is difficult for people to convince them that they will give up Type-C for a little bit of cost. The same is true for technical remarks. Will flash charging and Type-C be more difficult to implement than under-screen fingerprints? Besides, OnePlus 3 also uses VOOC flash charging technology, and has long used Type-C.
Type-Ch
application is not that widespreadIn the editor's opinion, OV insists on not using Type-C is determined by the consumer market. For OV, which focuses on online and offline promotion routes, consumers in third- and fourth-tier cities account for a relatively large proportion, and it is also difficult to find Type-C lines in offline mobile phone stores. It is said that is a common phenomenon. Now many people think that only Apple and Android data cables are two types. Many novice users do not know what Type-Ch is.
, and OV users account for a large proportion. For the convenience of users, the Type-C of these two companies will come relatively late. Well, only this explanation can be explained. More and more manufacturers' flagship phones have chosen Type-C interfaces, because the cost is higher than that of traditional Mirco-USB. Now, the promotion of thousand-yuan phones is still stagnant, but the first thousand-yuan phone using Type-C has also been released in the past few days. It is only a matter of time before
Type-C completely replaces mirco-USB. For this OV, it is still unscrupulous to not use Type-C, and netizens have also been teased by them, "When OV goes together, whoever uses Type-C is the dog."
. Who would you guess in the end will use Type-C first? Also, even Mijia’s razor has been put on Type-C. What reasons do future manufacturers have to make it?
