In the global flat-panel TV business, Samsung and LG both occupy their respective dominant positions. In the past five years, flat-panel TVs have gradually replaced older TV sets based on CRT structures in most countries around the world. Industry insiders expect that the total global TV shipments this year will be about 200 million units, and ultra-thin flat-panel TVs will only account for about 1%. Although the market share of ultra-thin flat-panel TVs is not high, it represents the direction of industrial development and can bring higher profits to manufacturers.
LG said its latest 55-inch ultra-thin TV will be available in South Korea and Europe in the next few weeks, priced at about $5,000. At present, Samsung's similar products are priced at about 4,000 US dollars. In contrast, a 55-inch flat-panel TV with a thickness of 3 to 5 inches is usually priced between $2,000 and $3,000. YoonHyuk-jin, an analyst at Shinyoung Securities, a South Korean investment institution, believes that due to increased market competition, the price of ultra-thin flat-panel TVs is expected to fall by the end of this year.
Due to the reduced cost of light-emitting diodes (LEDs), an important component of flat-panel TVs, a large number of new technologies can also be applied to ultra-thin TVs. Compared with the fluorescent tubes used in the old flat-panel TVs, the thickness of the LED tubes is guaranteed three years ago, and manufacturers have used LED tubes in LCD TVs, and named the LCD TV "LED TV". .
Samsung previously placed the LED tube on the side of the LCD panel and removed the circuit at the rear of the LCD panel, which made the thickness of the flat panel TV more secure. LG's latest ultra-thin TV still placed the LED tube behind the LCD panel. Department, but by other means to reduce the total thickness of the product.
Samsung said earlier this week that its side LED tube LCD TV shipments have reached 500,000 units. Samsung executives also predicted on Thursday that the company's new flat-panel TV sales this year is expected to reach 400,000 units.
The problem
Throughput is an important indicator of Ethernet testing. Many engineers believe that the Ethernet switching throughput should be its line rate, that is, no packet loss can occur at 100% traffic, and that it is illegal for the Ethernet frame interval IFG to be less than 96 bits. However, in the Ethernet switching throughput and packet loss rate test, a small amount of packet loss occurs in the long-term error test under the line speed condition. The reason is the cross-clock domain architecture of the Ethernet.
With the rapid development and application of industrial Ethernet technology, a large number of network problems have appeared along with it. According to statistics provided by Siemens, the network communication failure rate accounts for more than 70%, and the network equipment failure rate is less than 30%. After a network failure causes the system to shut down, the time required for fault diagnosis and location accounts for more than 80% of the total system downtime, while maintenance measures take up less than 20%. Therefore, real-time monitoring and analysis of network traffic is a major problem in the development and application of industrial Ethernet. Real-time monitoring and analysis of industrial Ethernet network traffic and timely detection and location of network problems play a vital role in improving the stable operation of the entire system. .
