Now many young people are buying smart TVs for their parents. Although they are filial, it is also a loss for parents not to buy them.
It is irrational to buy smart TVs for elderly parents. The operation of smart TVs is very simple for young people, but it is not as easy for older people to use them as traditional TVs. Smart TVs can be used as smart TVs. Is it normal TV use? The answer is certainly yes.
Smart TV as an ordinary TV method
The smart TV also has the interface of an ordinary TV, so the smart TV has no problem as an ordinary TV.
1. Connect an antenna to an ordinary TV to watch TV programs. Just insert the TV signal cable into the antenna signal input interface of the smart TV.
2. To connect a DVD player, set-top box, etc., simply connect the AV interface to the set-top box and the TV.
3. To watch live TV programs, simply press the source button on the remote control to switch the TV signal source to TV to watch TV programs.
4. When the user wants to use a DVD or set-top box to watch other programs, simply press the source button of the remote control to switch the TV signal source to AV to display the DVD player or set-top box.
Smart TVs are indeed suitable for young people. If parents at home don't adapt themselves to modern devices, their children remember to set smart TVs to be suitable for parents. Open them to see and use them best!
Aluminum circuit boards is a metal-based copper clad plate with good heat dissipation function. Generally, the single layer is composed of three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high tech use is designed as double layers, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with an insulating layer and an aluminum base.
Aluminum PCB characteristics
â— Surface Mount Technology (SMT);
â— Extremely efficient treatment of thermal diffusion in circuit design;
â— Reduce product operating temperature, increase product power density and reliability, and extend product life;
â— Reduce product size and reduce hardware and assembly costs;
â— Replace the fragile ceramic substrate for better mechanical durability.
Aluminum PCB use:
â— Audio equipment
Input, output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc.
â— Power supply equipment
Switching regulator, DC/AC converter, SW regulator, etc.
â— Communication electronic equipment
High frequency amplifier, filtering appliance, reporting circuit, etc.
â— Office automation equipment
