At present, there are more than 1.6 billion smartphone users in the world, and this 1.6 billion is the main body and core of the society. Mobile Internet has become an indispensable part of people's life and work, subverting the entire social life, including the business model, almost everything. Be transparent, before the popularity of mobile Internet, if customers have a bad customer experience, they may only be unlucky, and now, but now a customer's Weibo can make the world in 2, 3 seconds. Everyone knows that a company, a product, or a service promise has not been honored. Customers get the functionality of a certain product, and the price is easy to use anytime, anywhere. What kind of challenges will the LED industry face in the mobile Internet era? What kind of trend will LED products show? <1> Transparency (non-price war) In the past ten years, LED display companies have grown and sold in a closed environment because of their non-standard LED display and engineering properties. A series of problems caused by chaotic product models, chaotic quality, and chaotic prices. A market of less than 30 billion accommodates more than 2,000 companies and has a relatively large profit margin. The order is mainly based on the salesperson's ability to communicate and operate. However, the advent of the mobile Internet era has completely changed the closed mode of the LED display industry. Now when customers need LED display, they can find the company, product, price, etc. in a matter of seconds, everything is transparent. 1) The transparency of the company's comprehensive strength, the asymmetry of previous information, has ensured a LED display industry of less than 30 billion, and more than 2,000 companies are profitable. The information obtained by the customer to obtain the LED display supplier is not smooth. The main influence on customer decision-making is the salesperson who communicates with it. The contract is made in the promotion of the cup. In the era of mobile internet, the comprehensive strength of display company scale, case, sales, quality brand and so on is completely transparent, and customers have enough information to verify and verify the real situation. At this time, the largest companies in the LED display industry will first become the target of the customer. 2) Transparency of price: price transparency (non-price war) into the biggest impact of the mobile Internet era on the LED display industry. In a model of the chaotic LED display market, there are only a few mainstream models. Mainly P16 and P10. The main indoor is P6, P4. Before the LED display price is not transparent, mainly because the production company has no public price, so it is difficult to find the quotation on the website, but now with the scale of some enterprises in the industry Expansion, the beginning of standardized mass production, the price is open and transparent. Once the price of the LED display is transparent, the sales model of the entire industry will be completely subverted. 3) Corporate word-of-mouth transparency: Guo Meimei, Smile Director, Fang Jie Gong Ai, Lei Zhengfu and other series of events let us experience the tremendous social influence of information transparency in the mobile Internet era. The LED display of Haiyi Junyi Hotel in Hong Kong is on fire, the stage screen of Yangzhou Gymnasium collapses, and the Beijing rental customer group returns, etc., immediately after the incident spread throughout the LED display industry, the mobile Internet era will undoubtedly show the nakedness of the company. Large companies are even thinner, fearing that the name of a world is destroyed in a single (den). According to the understanding, in the era of all transparent interconnection, the LED display industry is a few happy ones. Engineering and trade are undoubtedly the catastrophe, and small and medium-sized companies are also precarious. Even large enterprises in the industry have to face the unfavorable situation of serious decline in profits after price transparency. Therefore, a boycott of price transparency will become a rare tacit understanding in the industry in a short period of time. However, the trend of price transparency is unstoppable. Under a brand-new business model, companies can only die if they make changes. The change must not only have capital but also pay the price. There are more than 2,000 LED display industries, and there are many people with strong capabilities and well-funded enterprises. But really face all the transparent business environment, perhaps no company can face it. The representative production scale, cost control, product quality, engineering services, etc. of several listed companies all have problems, and they dare not think about the consequences of all transparency. No company in the entire LED display industry likes to be transparent, but all transparency is inevitable. It is the evolution direction of the industry. I think every company wants to overtake in a corner. This is indeed the biggest change in the history of the LED display industry. The comprehensive strength and the transparency of the word-of-mouth are coming to an end. Only the transparency of the price has just begun. The strength of a corner overtaking is the key. After the integration of Dehao, the Ruituo show has become part of Dehao's whole game, not an independent unit, and Dehao was strategically placed a few years ago in Wuhu, Dalian, Yangzhou.èšŒåŸ There is a large investment, from LED epitaxial wafers, LED chips, LED packaging, to LED display standard mass production, using the huge capacity and price advantage formed by strong capital to release to the market, Dehao Group today just borrowed price transparency as a marketing tool I hope to complete the major changes in the sales model of the entire LED display industry. Therefore, the company will plan to promote the price transparency of each model in 2013. <3> In the process of influencing price transparency and gradual realization, the original LED display industry sales model will be completely subverted: 1) Solving the problem of information asymmetry, customers are more convenient and objective to find and trade with suitable LED display companies. . 2) Reduce the transaction cost, customers do not have to spend a lot of time to go to several factories to conduct on-the-spot investigations and then round and round negotiations and price reduction. 3) The product configuration is unified. The supplier must design a product with guaranteed quality for price transparency, and the product quality is more guaranteed. 4) It is conducive to the concentrated development of the LED display industry. After the standard is transparent, the market share of some enterprises will expand rapidly. Finally, a large international enterprise with international competitiveness will be formed, and the LED display industry will soon be more than 2,000. The number of homes has been reduced to a few. All the transparency process is accompanied by pain, price advantage and capacity advantage, strong capital management and perfect comprehensive enterprises with strong comprehensive strength will accelerate expansion, gradually encroach on the market of small and medium-sized enterprises, 1) returning profits after all transparency, many poor management The company lost its competitive ability and gradually withdrew from the market. 2) The transparent price will once again impact the previous release of the price when the price is high, especially the rental market, all of which are private debts, and the display is a non-standard product. It is easy for customers to find reasons not to pay. The change of society is like the alternation of the sun, the moon and the stars. Whether it is an individual or a company, it seems to be small and powerful, and can only sigh.
LED Packages
LED (semiconductor light-emitting diode) packaging refers to the packaging of light-emitting chips, which is quite different from integrated circuit packaging. The packaging of the LED is not only required to be able to protect the wick, but also to be able to transmit light. Therefore, LED packaging has special requirements for packaging materials.
- outline
Generally speaking, the function of the package is to provide sufficient protection for the chip to prevent long-term exposure or mechanical damage to the chip in the air to improve the stability of the chip; for the LED package, it also needs to have good light extraction efficiency and good heat dissipation. , A good package can make the LED have better luminous efficiency and heat dissipation environment, and then improve the life of the LED.
- Technology Introduction
1. Expand the crystal, open the densely arranged chips a little bit to facilitate the crystal bonding.
2. Die-bonding, point conductive/non-conductive glue on the bottom of the holder (conductivity depends on whether the chip is a top-bottom PN junction or a left-right PN junction) and then put the chip into the holder.
3. Short bake, so that the chip does not move when the glue cures the bonding wire.
4. Wire bonding, use gold wire to connect the chip and the support.
5. Pre-test, preliminary test whether it can be bright.
6. Fill the glue and wrap the chip and the bracket with glue.
7. Bake for a long time to allow the glue to solidify.
8. Post-test, test whether it can be bright or not and whether the electrical parameters meet the standard.
9. Light and color separation to separate products with roughly the same color and voltage.
10. Packaging.
