Several tips for selecting 7 segment LED display screen products

Several tips for selecting a 7 segment LED display screen product: device orientation and shape at the light outlet, incoming material markings, and the role of contact adhesive.

● Solidification, soldering, sealing, splitting, packaging.

LED, also known as LED, is a solid-state semiconductor device that can directly convert electricity into light. Its heart is a semiconductor chip, one end of which is attached to a bracket, one end is a negative electrode, and the other end is connected to the positive electrode of the power supply, making the entire chip encapsulated in epoxy resin. A semiconductor chip consists of two parts, one is a P-type semiconductor in which holes dominate, and the other is an N-type semiconductor in which electrons dominate. But when these two semiconductors are connected, a "P-N junction" is formed between them. When an electric current passes through a wire and acts on this chip, electrons are pushed towards the P region, where they recombine with holes and emit energy in the form of photons. This is the principle of LED luminescence. The wavelength of light, also known as the color of light, is determined by the material that forms the P-N junction.

LED, also known as semiconductor LED, is a semiconductor material that can convert electrical energy into light energy. It is truly 'green lighting'. So what is the full name of LED, semiconductor LED? This is because LED lights are made of semiconductor materials. Can produce various shapes of LED lights. LED lamp feet.

At a time of vigorous development in the optoelectronic industry, the application of semiconductor packaging in Songyou Electronic Semiconductor LED is still in the stage of signal extraction. As of now, with only human participation, independent research and development can be achieved. The current power and electricity consumption of Songyou Electronics is expected to reach 22 million pieces per nickel cadmium package on the same substrate, which can produce various light efficient and high light efficiency packaging forms such as nickel hydrogen and nickel cadmium. At present, there are several packaging forms of "borderless nanocrystals" that we represent.

Nickel hydrogen SKD80, nickel cadmium Tstte523, GZ TO-252, GZ, Zn150, GZ80.
