The lowest as long as 799 yuan commercial 5.2 inches small screen phone recommended

In recent years, the trend of the mobile phone screen has been continuously increasing, but to a certain extent, the negative impact brought by the large screen is obvious. The most direct impression of a large screen is the improvement of visual impact. Some large-screen mobile phones can already be comparable to small-sized tablets in screen size. The screen is getting larger and smaller, and the possibility of misoperation when tapping is getting smaller and smaller, but it also brings some problems, such as: the decline of portability, one-handed operation inconvenience. Therefore, relatively small screen phones are still deeply loved by some consumers.

Once upon a time, five-inch screens were big screens in mobile phones, but they are now the critical line between small-screen phones and large-screen phones. Even 5.2 inch screen phones are a bit small for some people. Big and small have always been relative, nowadays not only 4 inches or so of mobile phones can be called small screen mobile phones, that is, about 5 inches of mobile phones also belong to the category of small screen mobile phones, the standard of large screen mobile phones has been raised to 5.5 inches or more.

The comfort of large-screen phones in one-handed operation is not as good as that of small-screen phones. Even if one-handed mode is provided, the feeling of easy control on small-screen phones cannot be realized on large-screen phones. For consumers who value the one-handed operation experience, it is best to select a mobile phone with a screen size of 5.2 inches or less. Such a mobile phone is relatively small in size, but it is relatively easy to control with one hand. If you can't accept the inconvenience caused by large-screen phones with 5.5 inches or more, you should choose a phone with a relatively small screen.

Conductive Slip Ring

Conductive slip rings are one of the most popular types of electrical connectors. They consist of an insulating sleeve enclosing two metal contacts, with a small gap between them. When current is applied to the ring, it creates resistance between the contacts, which can be used to form a continuous circuit. They can be used in a wide range of applications, such as medical equipment, robotics, aerospace systems, and more. The construction of a conductive slip ring typically consists of two rotors (or rings), with each one containing a number of stationary contacts. When the rings rotate, the contacts move past each other and create an electrical connection.


In today's increasingly electronic world, the need for efficient and reliable power transmission is more important than ever. That's why more and more businesses are turning to slip rings as a means of transmitting power in a variety of applications. Slip rings are electrical connectors that allow current to flow continuously through a rotating assembly, making them ideal for use in devices that require uninterrupted power transmission, such as motors, generators, and wind turbines.

Conductive Slip Ring
