First, the difference between smart TV and ordinary TV
A smart TV is an open system (such as Android) added to an ordinary TV. It can install and download third-party applications. Its entertainment performance is higher and it can meet the individual needs of users.
Smart TV features
Compared to ordinary TVs, smart TVs are very versatile. Common functions include multi-screen interaction, that is, by using terminals such as mobile phones and tablets, other multimedia files such as music, pictures, videos, etc. can be pushed to other devices for sharing.
Voice operation, smart TV with voice remote control, users can adjust the TV through the password, complete such as channel change, browse the web, text input, download, shutdown and other operations.
Gesture operation, the user can identify the specific gesture commands through the camera of the smart TV, and then control the TV. The user needs to flick a few palms in front of the screen. After a few seconds, the mouse cursor will appear on the screen, and a prompt box will pop up below to tell you how to operate - the palm movement is to bring the cursor, and the fist is "click". command.
Smart application software allows users to download software from the smart TV application market, or install third-party software through U-disks. Since smart TVs are generally equipped with an Android system, so many APP software can be installed, for example, on-demand software, live software, game software (2D, 3D, somatosensory, Android games), educational software (children's early childhood education, adult education, elite schools Open class), chat tools, etc.
Second, how to choose smart TV?
1, first of all depends on the product's brand, quality, price, and after-sales service. The domestic market is relatively good such as: Samsung, Xiaomi, Hisense, LG, Konka and so on.
2, then we must look at the screen: size, according to their own choice of size; resolution, market, many are 720p, 1080p, better is 2k or 4k.
3, then we must look at the smart TV's internal hardware configuration: CPU, GPU, memory, storage, etc.: CPU (central processing unit) is the core of a smart device, the device is good or bad depends on the quality of the CPU: GPU (Graphics processor): The picture is good or bad depends on it; Memory: If you compare the CPU to the masher, the memory is the feed port; Storage: save the photos, audio, video recordings.
4, the last depends on the after-sales service, if the after-sales service is not good, the TV is broken and there is no place to repair, consumer rights and interests are not protected.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
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.
