Mainland China Mobile Phone Factory Spreadtrum officially announced the launch of the first 4G data chip SC9620 on the 18th. Spreadtrum pointed out that this solution has been adopted by land mobile phone brands such as Lenovo, Coolpad and other three-mode 4G smart phones, and has begun to be sold on the mainland market. .
Spreadtrum's new 4G data chip, and the MediaTek's first 4G data chip MT6290 official production output time only a difference of about a quarter, plus similar number, follow-up will affect the MediaTek 4G chip sales? Great attention.
Li Liyou, chairman and chief executive of Spreadtrum, pointed out yesterday that the introduction of this chip represents the company's product line has been expanded to 4G smart phones and tablet computers, and will also promote the continuous growth of Spreadtrum mobile phone chip shipments.
Spreadtrum said that the SC9620 data chip announced this time is to support Category 3 of the 3GPP R9 protocol, with a maximum downlink speed of up to 150 Mbps for 4G smart phones, tablet computers or other data terminals. At the same time, Spreadtrum also released a three-mode public board solution for the Chinese mainland market, and is expected to launch a five-mode solution by the end of this year.
According to IC Insights statistics, Spreadtrum’s annual production value in 2013 was US$1.070 billion, ranking 14th in the world. Although it ranks behind Qualcomm, MediaTek and even Morningstar, its annual growth rate is as high as 48%, making it the top 25 IC design in the world. The fastest growing company in the company.
Since Spreadtrum was acquired by the mainland's Tsinghua Unisplendour Group for US$1.78 billion in July last year, Shengchuan will be re-listed after the merger with RDA (RDA), another IC design company in mainland China in the second half of the year, thereby accelerating the long-term development of Spreadtrum. The strength of R&D will undoubtedly affect Qualcomm and MediaTek, the world’s two largest manufacturers, once the case is formed.
It is understood that Spreadtrum currently has about 2,400 R&D personnel in the mainland and almost 200 overseas, and it is planning to rely heavily on overseas recruiting because it is unable to recruit key talents in the mainland.
Li Liyou told mainland media in July this year that it expects the entire company to hire nearly 10,000 people in the next two to three years. According to Spreadtrum’s annual revenue, about 20% to 25% of revenue will be spent on R&D and R&D. The expenses of personnel, the related capital demand is very large.
Introduction to LED peripheral products: all Led Display screens are composed of peripheral products. The surrounding products are mainly divided into these categories.
I. video processor, which is often used in engineering and leasing. Image zooming.
The display mode of Led Display Screen is point-to-point, which determines that the LED display screen can only display pictures with the same physical resolution size as itself. LED video processor can zoom the image, output the picture in any size, and map the whole desktop to the Led Screen.
2. Signal conversion and switching
Video processing equipment can complete the format conversion among many signals. Another important function of the video processor is to manage all kinds of signals when there are multiple access signals, and to switch between them flexibly.
3. Image quality improvement
Because the pixel spacing of LED display is much larger than that of other flat-panel display media, there are strict requirements for image processing technology, especially image enhancement technology. High quality LED video processor can use advanced algorithms to modify the signal with poor image quality, perform a series of processing, such as de interlacing, edge sharpening, motion compensation, etc., to enhance the details of the image and improve the image quality.
4. Large screen splicing
At present, the point spacing of LED screen is becoming smaller and smaller, and the overall dimension is becoming larger and larger, which makes the physical resolution of LED screen become very large. LED video processor with splicing function can drive large-resolution screen, which is a very cost-effective driving mode.
5. Multi screen processing
In many special scenes, a display screen needs to display multiple images with the same or different signals. The video processor with multi image processing function can flexibly meet such display requirements.
Due to the influence of regional weather and other factors, the outdoor display screen requires the video processor to have more excellent image quality improvement ability and advanced image scaling algorithm to ensure the sharpness and gray level of the image to the greatest extent after the video image is scaled. In addition, the video processor is also required to have a wealth of image adjustment options and effects to process the image brightness, contrast and gray level, so as to ensure the soft and clear screen output.
II. Air plug connector. Power and data are transmitted between boxes through air plug connector. The air plug is mainly divided into male head and female head. It is divided into indoor and outdoor according to the use scenario. His use makes the connection fast and safe.
3. Wire, the wire is mainly divided into 1 and 5V power lines, the wire connecting the power supply to the card, 2 and 220V power lines, the network cable connecting the power supply and the power supply, 3, the signal network cable, the network cable connecting the receiving card and the receiving card, 4, the cable arrangement, the cable arrangement between the module and the module and between the receiving card and the module. 4. Card wire, wire connecting receiving card and power supply
IV. receiving card is mainly used to receive data processing data and set screen parameters according to screen.
V. main card: the main card is divided into synchronous sending card and asynchronous card. The synchronous sending card is the synchronous display of the computer or other signal sources. The asynchronous sending card is to preset the content, send and store. Then the signal is off the external link.
Vi. power supply, which is mainly used to provide transformer power for screen body, also called transformer.
7. Box structure, mainly including die-casting aluminum box and iron box according to material classification, simple box and waterproof box according to use.
Peripheral products are selected according to customers' requirements, with various brands.
