The hot memory of the May 1st color circle seems to have not faded. In the interview with the chain store, the reporter learned that from the product layout of each brand, LED will undoubtedly become eleven. The absolute protagonist of the Golden Week, the high-profile LED behind it means that the LCD is about to be laid off
In front of the stage: Brands are holding LEDs
At the end of August, although there is still more than a month away from the 11th color TV gold war, the brands have begun to enter the strategic deployment stage. The reporter learned in an interview with Nanjing Gome that the sales volume of the eleven LEDs this year is a breakthrough. At least 40% of the products should be ignored. From the current layout of various brands, LED products have accounted for more than 60% of all sample products. The old name Changhong is the first to launch a large-scale LED popularization storm to stimulate LED sales with real preferential prices.
In addition, for the price issue that the people are most concerned about, the salespersons at the store said that under normal circumstances, the difference between the LED and the LCD of the same size segment is between 1000 yuan and 1,500 yuan, but at present, very colorful electric brands have begun to launch low-end LEDs to impact. LCD market, by reducing the spread to popularize LED.
In the random interview with consumers in the store, the reporter learned that in the face of the price difference, most consumers will still choose LED, and give up LCD. After all, LED is obviously superior in terms of image quality and energy saving. On the LCD.
Behind the scenes: layout LED industry chain
The person in charge of Hisense, who first played with LEDs, said that compared with the traditional LCD, it has the characteristics of high image stability, close-up viewing without hurting the eyes, slimmer shape, and energy saving. Therefore, if the price is not much different, choose LED. Consumers will be more and more. At the beginning of the year, Skyworth has clearly stated that in 2010, the new strategy “new products only lock LEDâ€, Qingku LCD has become a unified action of the brand tacit, and currently domestic color TV companies have joined the ranks of cleaning LCD inventory, the Internet TV pioneer TCL also uses LED P11 as the most powerful competing product.
The layout of the LED industry chain has played a fundamental role in promoting the popularity of LED. After the upstream production line of Konka, the first phase of the Tsinghua Tongfang Nantong LED Semiconductor Industrial Base has been officially laid. This is the development of a high-brightness LED application industry base in Nantong after the establishment of LED chip and LCD TV LED backlight industry bases in Beijing and Shenyang. At present, Tsinghua Tongfang has mastered the LED epitaxial chip and chip packaging technology applicable to LCD TV LED backlight products and indoor functional lighting; completed the technical development of LCD TV LED backlight module products and high-power functional lighting devices, among which LED backlight module The products have been successfully put on the market; LED high-power functional lighting products are also about to enter mass production. The construction of Nantong LED industrial base, Tsinghua Tongfang's LED industry layout has been basically completed, and fully entered the "LED industry era." At the same time, in China to achieve high-brightness, high-power LED epitaxial wafer, chip scale production, will help change High-end products are monopolized by foreign countries, reducing production costs and improving the international competitiveness of China's LED industry.
Thinking: How far is the LCD from being laid off?
The price reduction and behind-the-scenes layout have directly promoted the popularity of LED. As the price gap narrows, more consumers have chosen LED-backlit LCD TVs in their upgrades from CRT to flat-panel TVs. Will the 11th Golden Week this year become an inflection point in the LED and LCD layout? Will the LCD be laid off?
People in the industry have pointed out that LCD delisting and CRT delisting in the same year is still very different. After all, the difference between LED and LCD products is much smaller than CRT and LCD. Although the LED momentum is fierce, it seems that LCD is going to be laid off. It is still too early, and some insiders pointed out that at least for two years, LCD will not withdraw from the market.
Domestic communication, 4 g module in addition to support two kinds of LTE FDD LTE/TD - LTE standard, also compatible with 2 g / 3 g down, support td-scdma/WCDMA/EDGE/GP/GSM/CDMA1X/EVDO mode. The data service downstream rate can reach up to 100Mbps, the uplink rate can reach up to 50Mbps, providing customers with high-speed Internet access and wireless data connection and other functions. In addition to providing high-speed data access, it also provides voice, SMS, communication book and other functions, which can be widely used in notebook, tablet, touch screen communication devices, smart phones, video surveillance, multimedia mobile phones and vehicle equipment and other terminal products and vertical applications. Today, I will introduce you to what is 4G module and how to use 4G module.
What is 4G module
4G module said TD-LTE and FDD-LTE and other LTE network standards are collectively referred to. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. 4G module refers to a product whose hardware is loaded to the specified frequency band, software supports the standard LTE protocol, and software and hardware are highly integrated and modular. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Second, how to use 4G module
The 4G module is usually inserted into the circuit board or the patch module is welded to the circuit board, and the corresponding SIM card is inserted, and the network is connected through the 4G cellular network. In the common transparent transmission mode, data can be directly sent to the target server through the 4G module, and the 4G module can receive data from the server at the same time, and send the data to the serial port, which is received by the serial port device connected to the 4G module. Users do not need to pay special attention to the data conversion process between serial port data and network data packets, only need to insert the module to the target position, simple connection and parameter setting, you can achieve transparent transmission between the serial port and the network end.
What is the 4G module How does the 4G module work
4G module, also known as 4G transmission module, 4G communication module, 4G LTE module. It is a kind of hardware loaded to the specified frequency band, the software supports the standard LTE protocol, and the software and hardware are highly integrated modular products, with good compatibility, fast communication speed, large amount of communication data, wide network spectrum, communication flexibility and other characteristics, widely used in electric power, environmental protection, finance, industrial automation and other fields.
The working principle of 4G module
It has the characteristics of fast communication speed, wide network spectrum and flexible communication. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions.
