And all these live visual impact should be attributed to LED display, all kinds of bright light and video from Screens are about LED screen, thus, we must be cuirous why there existed LED display? what is it originarily from? well, it is a long story about it, Many scientists in the last and different periods discover and improve it, from red, yellow, and blue, for the development of the LED display, people have done this for a long time, so todayâ??s LED display technology is able to see further, it was only because it stood on the shoulders of giants.


1, what is the led display LED Display (light-emitting diode display)is a screen display technology that uses a panel of LEDs as the light source, and can emit different color light by special arrangement. LEDs are small electronic devices which produce a very efficient light source. A typical LED display is composed of many LED panels, which are used as a form of illumination or for display.

The LED display is basically are designed by pixels, modules, panels and displays.
LED Pixel is the smallest unit that forms LED screens. LED Pixel is created with 3 different RGB colors as Red (R), Green (G) and Blue (B). The combination of these LEDs in different colors forms an LED pixel.
LED Module refers to the group of pixels that make up the LED screens. This is the group of LED panels that forms the cabinets.
LED Cabinet A certain number of LED modules are mounted on special constructions,The combination of cabinets creates full-screen images.

More specifically, LED display screen is made up of a series of LED chips to range, it is also named as LED dot matrixes. The distance between LED chips is named pixel pitch, for example, the P3 LED display screen with 3mm pixel pitch consists of several 3mm pixel pitch modules.

The smaller the pixel pitch is, the bigger the pixel density is, the higher the module resolution is, the clearer the screen is. but that does mean the LED display with the smallest pixel pitch is the most proper LED display, because that depends on your requirements like used in indoor or outdoor? your budget? Does power provide? and the viewing distance? those are the necessary elements we need to take into consideration when we choose LED display.

2, What is the advantage of LED display compared to the traditional lighting device?
Aside from being power efficient, LEDs produce more brilliance and greater light intensity which show a better visual impact, which indispensable in various entertainment activities. maybe that the name of Bright Lights, Big City come from! As I shared above, LED display gained great popularity for their strong advantage, what are they?

What is Flexible PCB?
Flexible printed circuit boards, also called Flexible PCBs or Flex PCBs, derive their name for their ability to enable the circuitry to be designed to fit the electronic device or product, as opposed to building the device to conform to the circuit board. Immersion Tin PCB are characterized by a distinctly patterned printed circuitry and component arrangement highlighted by a malleable base material.
What are Advantages of Flexible Printed Circuit Boards?
Flexible printed circuit boards offer a number of potential benefits including:
Saving Space. Flex PCB design requires only about 10 percent of the space and weight of an ordinary circuit board assembly, offering greater installation and packaging freedom. The inherent flexibility also permits tighter bend capabilities.
Maximum Reliability. A flexible printed circuit board requires fewer interconnects, which in turn requires fewer contact crimps, connectors and solder joints. Simply put, a flexible PCB board does not contain as many potential sources for failure, which enhances their reliability.
Enhanced Capabilities. The flexible printed circuits boards are compatible with virtually any type of connector or component and works well with options such as ZIP connectors. They also perform extremely well in extreme temperatures and offer superior resistance to radiation and chemicals.
Cost Savings. Cost-saving advantages of Flexible PCBs include reduced material and packaging demands, lower parts replacement costs and assembly errors that could result in the need for repairs.
Thsse benefits make flex PCBs ideally fit for a wide range of applications in industries such as Military, Transportation, Medical, Consumer Electronics, Automotive, Aerospace, Communications and Industrial.

What is HDI PCB
High density interconnect (HDI) PCB, represent one of the fastest growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design is able to incorporate smaller vias and capture pads, and higher connection pad densities. HDI Boards contain blind and buried vias and often contain micro vias of 0.006 or less in diameter.
By using HDI technology, designers now have the ability to place more components on both sides of the raw PCB if desired. Now as the development of via in pad and blind via technology, it allow designers to place smaller components closer together. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
HDI PCB is regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras, 4G network communications, also prominently featured in medical devices.
Advantages of HDI PCB
The most common reason for using HDI technology is a significant increase in packaging density. The space that obtained by finer track structures is available for components. In addition, overall space requirements are reduced will result in smaller board sizes and fewer layers.
Usually FPGA or BGA are available with 1mm or less spacing. HDI technology makes routing and connection easy, especially when routing between pins.

The LED lighting PCB comes into being with the rapid development of printed circuit PCB industry. Some LEDs were soldered on PCB to created lighting electronic products.
As we all know that LED will generate more heat compared with other electronic parts, which required the PCB to have better ability for dissipating heat. For this special requirements, metal core PCB are frequently used on LED PCB, especially aluminium core PCB. This is because the aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional rigid PCB.
The application of LED PCB
Telecommunications:LED indicators and displays are always used for telecommunications equipment because of the surrounding machinery, the excellent heat transfer ability. So aluminum-based LED PCBs is extremely useful in this application.
Automotive: Aluminum PCB LEDs also used in cars on indicators, in headlights and brake lights, and other applications. The durability and competitive price makes these Aluminum Fr4 PCB Manufacturer ideal within the automotive industry.
Computer: LED displays and indicators are becoming more and more common within computer applications, and the heat sensitivity of computer machinery makes aluminum PCB LEDs the ideal solution. In addition to LED applications, computer parts like power devices and CPU boards are commonly use aluminum PCBs because of their ability to dissipate and transfer heat.
Medical: Lighting tools used in surgeries and medical examinations commonly use high-powered LED lights, and these LED lights often use aluminum PCBs. This is primarily due to the durability and heat transfer capabilities of aluminum PCB LEDs â?? this ensures medical equipment is functioning properly regardless of the number of patients cycling through a medical office. In addition to lighting tools, medical scanning technology often uses aluminum PCBs as well.

Thick-Copper PCB
With the highly development of telecommunications and electronics industry, thick copper board is widely required by PCB customer. Thick copper PCB is mainly used for central power system and power electronic devices, which is because it enables the board to conduct higher current and decrease the product size.
China thick copper board mean the finished copper thickness of the board is more than 4OZ(140um), this is the most important factor for us to compare the thick copper PCB from those standard PCB with 1OZ or 2OZ copper.

High-TG PCB High Temperature PCB fr4 Material
The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from a hard, glassy material to a soft, rubbery material.
Circuit board material must flame-resistant, it canâ??t be burned at a certain temperature and only be soften. The temperature point is called the glass transition temperature (Tg).
The higher Tg point means higher temperature requirement during lamination. And the Aluminum clad Circuit Boards will be hard and crisp, which will affect hole and the electrical properties.
Ordinary PCB materials at high temperatures, not only will be soften, deformation, melting and other phenomena, but also the mechanical and electrical properties decline sharply.
General fr4 Tg is 130-140 centigrade, moderate Tg is greater than 150-160 centigrade, High-Tg is greater than 170 degrees.
The higher of Tg, the better performance of PCB heat resistance, moisture resistance, chemical resistance, stability and other characteristics.
FR4 is a code name for grade of Epoxy Glass material.
Tg means Glass Transition Temperature.
When the working temperature reaches to the melting point, that means the temperature exceeds the Tg value, the status of pcb material will be changed from glassy to liquid, which will affect the function of pcb. And this value is related to the stability of the pcb dimension.
As usual, made with Tg â?¥ 170â?? pcb material, which is called high Tg printed circuit board. With the rapid development of the electronics industry, high Tg material is widely used in computer, communication equipment, precise apparatus and instrument and etc.
