LED industry 2nd season season effect continuous no matter is upstream chip plant and downstream package plant all appear capacity short supply of phenomenon. According to the growth of orders, the May revenue performance of many Taiwanese companies is expected to rise, including the performance of Yiguang, Hongqi and redefick are expected to hit a record high in a single month. In April, the price of LED bulbs fell slightly. The survey on the retail price of new LED bulbs showed that the average retail price of LED bulbs replacing 40W in April 2014 was 1. 5 fell slightly to 14. 7 US dollars, of which the price in China fell significantly. Replace the average price of 60WLED bulbs by 2. 5, reaching 20. $2. Season effect continuous LED enterprise May revenue is expected to record LED industry 2nd season season effect continuous no matter is upstream chip plant and downstream package plant all appear capacity short supply of phenomenon, the May revenue performance of many companies in Taiwan is expected to rise, including the performance of Yiguang, Hongqi and redecke are expected to hit a new record high in a single month. TSMC 28 nm 3DIC is ready to go. In order to lay out the 3DIC technology field, TSMC actively cultivates upstream and downstream integrated services. On the technical side, it was announced two years ago with SK Hynix (SKHynix) Cooperate with 3DIC test chip, and cooperate with DRAM for the first time. TSMC's strategy in this field is also open. It does not rule out alliances with any memory partners. Therefore, it has joined hands with the second memory Micron to build 3DIC chips. IWatch may support wireless charging. It is reported from Apple supplier that iWatch, Apple's first wearable device, will be equipped with wireless charging function. At present, the supplier has submitted the wireless charging coil for review, waiting for relevant authentication results. The report also revealed the release plan of iWatch, saying that iWatch will be unveiled in the second half of this year, depending on the production situation. Industry view: we suggest to pay attention to Apple Industry Chain companies such as Gol acoustics and Desai battery ( IPhone6 stocking is expected to pull up a round of orders in the second quarter); We believe that 2014 will be a real lighting year for LED. The upper, middle and lower reaches of the industrial chain will be driven by downstream demand. Industrial integration and new model evolution will become the theme of the industry, we suggest paying attention to Aoyang Shunchang ( LED chips began to be released, and traditional enterprises began to successfully enter the LED industry, which is expected to rise suddenly)Sanan Optoelectronics ( The supply and demand pattern of LED chips is tight, and the price of chips is firm, which is conducive to the improvement of the company's profitability), Jufei Optoelectronics ( It will further benefit from the increase in backlight share of low-cost tablet computers and flat-panel televisions, and the recent decline will make the company's long-term investment value appear)Zhou Ming technology ( The proportion of small spacing shows an increase, and e-commerce channels will begin to make efforts in lighting in 2014. The company will directly benefit from the innovation of channel mode)Liad ( The company's small-pitch TV has a leading edge, technology and customer layout are other manufacturers, and it is expected that the second quarter will be the beginning of high growth in shipments). The integrated circuit industry support policy is expected to fall in the near future. We believe that the new round of state support policies will be superior to the past, and the market-oriented mechanism will be rationalized in the form of industrial funds, which will set off a new round of integration and growth of integrated circuits. We suggest paying attention to Huatian Technology, Changdian technology and Jingfang technology in the short and medium term.
