Ameya360:LCD Monitor Shipments Forecast to Return to Pre-Pandemic Level for 2023

　　LCD monitor shipments are estimated to reach around 135 million units for 2022, showing a year-on-year (YoY) drop of 7%, according to TrendForce. Even though shipments on the whole were relatively stable during the first half of 2022 (1H 2022), the demand from the commercial segment of the LCD monitor market slowed down significantly in 2H 2022 as enterprises were scaling back their budgets.　　Furthermore, the effects of the ongoing inflation and rising interest rates became more prominent over time, and the demand for consumer electronics fell considerably as a result. This development thus impacted the consumer segment of the LCD monitor market during 2H 2022. Regarding 2023, the pandemic-related demand has subsided, and there are still a lot of uncertainties with respect to the course of the global economy and politics. Given this situation, TrendForce projects that LCD monitor shipments will return to the pre-pandemic level, coming to around 127 million units and registering a YoY decline of about 5.8%.　　TrendForce states that LCD monitor shipments on the whole were relatively stable during 1H 2022. In 2Q 2022, the demand for LCD monitors did experience a freeze because of the Russia-Ukraine military conflict. The ongoing global inflation was exacerbated by this geopolitical event, thereby compelling consumers to allocate a greater share of their budgets to daily necessities and reduce their spending on consumer electronics.　　However, commercial customers in Europe and North America still had some leftover portions of earlier orders that were originally scheduled to be fulfilled in 2021. The release of this deferred demand not only helped prop up LCD monitor shipments for the entire 2022 but also enabled HP to climb back to second place in the global ranking of LCD monitor brands by annual shipments.　　The annual total shipments of the global top 10 LCD monitor brands are forecasted rise by about 1% YoY for 2023. This projection is based on the top 10 brands’ respective shipment targets for the year. Now, with the arrival of 2023, orders from commercial customers are showing a substantial shrinkage. Therefore, Dell and HP have lowered their annual shipment targets.　　The target that Dell has set for 2023 is 11.4% lower than its shipment result for 2022. As for HP, the target it has set for 2023 is 3.1% lower than its shipment result for 2022. Turning to Chinese commercial monitor brand Lenovo, its target for 2023 is almost on par with its shipment result for 2022.　　Conversely, consumer monitor brands have significantly raised their annual shipment targets for 2023 because most of them posted a weak shipment result for 2022. Nevertheless, the scale of the entire LCD monitor market is expected to keep shrinking during 2023, so raising shipments is going to be a fairly challenging endeavor.　　TrendForce believes that maintaining profitability by upgrading specifications may be more important for monitor brands than simply increasing unit shipments. For instance, monitor brands could introduce more high-end OLED monitors, or they could follow the two major brands Dell and Acer in replacing the existing 60Hz or 75Hz products with 100Hz ones. These are some of the specification upgrades that could help retain a healthy profit margin.

What is the difference between MOSFET and IGB

　　MOS transistor is MOSFET, Chinese full name metal oxide semiconductor field effect transistor, known as gold oxygen half effect transistor is a kind of field effect transistor can be widely used in analog circuits and digital circuits. Because the gate of the FET is isolated by an insulating layer, it is also called an insulating gate FET. Mosfets can be divided into N channel depletion type and enhanced type. There are four major types of P-channel depletion and enhanced. Next, Ameya360 electronic components purchase network will introduce to you!　　IGBT is an insulated gate bipolar transistor. It is a compound fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate FETs). It combines the advantages of high input impedance of MOSFET and low on-voltage drop of GTR. The saturation voltage of GTR decreases, the current carrying density is high, but the driving current is high. MOSFET has low driving power and fast switching speed, but large conduction voltage drop and low current carrying density. Igbts combine the advantages of both devices, with lower driving power and reduced saturation voltage. It is very suitable for converter system with DC voltage of 600V and above, such as AC motor, frequency converter, switching power supply, lighting circuit, traction drive and other fields.　　There are many types of MOSFeTs, but the most comparable to IGBTs are power MosFeTs. It is designed to handle significant power levels. They are only used in the "on" or "off" state, making them the most widely used low-voltage switch. Compared to IGBTs, power mosFeTs have faster reversing speed and higher efficiency when operating at low voltages.　　What's more, it can maintain high blocking voltage and high current. This is because most power MOSFET structures are vertical (not planar). Its rated voltage is a direct function of the doping and thickness of the N-epitaxial layer, and its rated current is related to the channel width (the wider the channel, the higher the current). Because of their efficiency, power MosFeTs are used in power supplies, DC/DC converters, and low voltage motor controllers.　　MOSFET and IGBT insulated gate double maximum power tubes and other devices have an insulated silicon structure between the source and gate, and DC current cannot pass through, so the low-frequency behavior drive power is close to zero. However, the grid capacitor Cgs are formed between the grid and the source, so some dynamic drive power is required when the high frequencies are alternately switched on and need to be switched off.　　Due to the large gate capacitance Cgs, low power mosFETs typically have Cgs between 10-100pF for high power insulated gate power devices. Usually between 1-100nF, large dynamic drive power is required. In addition, grid drive power is generally not negligible due to the drain-to-grid Miller capacitor Cdg. Due to the current trailing effect of IGBTs, better immunity is required during downtime and negative voltage drive is required. Mosfets are fast and can be turned off without negative voltage, but when interference is severe, negative voltage off is very good for improving reliability.　　MOSFET is used in switching power supply, ballast, high frequency induction heating, high frequency inverter welding machine, communication power supply and other high frequency power supply, IGBT focuses on welding, inverter, inverter, electroplating power supply, super audio induction heating and other fields.

Ameya360:Has Adoption of ‘Connected Devices’ Outpaced Security?

　　We’ve all seen the rush to deploy the new wave of connected devices but the speed at which these devices have been embraced may threaten fundamental security protocols.　　We love the convenience that ubiquitous connectivity brings us; our cars can reroute us based on traffic jams, we can adjust our lights or AC without leaving the couch, we can get up-to-the-minute blood glucose readings, and we can precisely monitor energy flow across a smart grid and optimize manufacturing with smart factory floors.　　Aided by technologies such as Bluetooth Low Energy, WiFi, and 5G, the pace of Internet of Things (IoT) deployment continues to accelerate. However, in a recent Forrester report, 69% of surveyed respondents estimate that at least half of all devices on their enterprise network or internet-of-things (IoT) are unmanaged, and 26% estimate that unmanaged devices outnumber managed devices on their network by three to one.　　Well, as with any new technology, there are going to be drawbacks. Among the most significant: our ability to build and deploy intelligent, connected devices has outpaced our understanding and practices of how to secure them.　　We’ve seen large botnets take over farms of IoT devices and shut down large chunks of the Internet, a recent escalation in healthcare organizations hit by ransomware attacks impacting connected medical devices, and privacy breaches impacting everything from baby monitors to smart watches.　　Lessons for ‘connected device’ security—Think like an attacker　　IoT devices really are special. For traditional IT devices, like Linux servers and Windows laptops, we have established best practices for security. It isn’t perfect, but in reality, if we keep the operating system and any endpoint security software up to date, we’ll eliminate the majority of system vulnerabilities. In fact, an analysis earlier in 2022 showed that flaws from 2017 and 2018 were still among the most commonly exploited today; a simple and free OS update would have blocked them.　　IoT devices, however, are more often black boxes – we don’t know which version of what operating system they’re running, or which versions of what libraries, and even if we have that information, we can’t force an update; we typically have to wait for a patch from the manufacturer.　　There are no standards or real consistency for tracking security flaws across connected devices; the only way we can understand where the problems are is to test them ourselves. Then, armed with a better understanding of how IoT devices are impacting our attack surface, we can deploy targeted mitigation strategies to address the vulnerabilities we’ve discovered.　　This is, of course, good information to have and a good strategy to pursue. But how do we know that our defensive tools, the stack of network, cloud, email, and endpoint security tools that we array to keep both our traditional and nontraditional IT devices safe, are working? How do we know if an emerging threat is able to slip through our firewall, or run undetected on an endpoint, or make it through our email gateway to target an unsuspecting phishing victim?　　The same principle applies; we really need to test our defensive stacks, on a continuous basis, to make sure they’re optimized and tuned to catch the latest attacks that threat actors are deploying against us. This lets us, finally, go on the offensive and think like an attacker – we can test and probe our networks and devices ourselves, discovering vulnerabilities and attack paths ourselves, rather than waiting for a bad guy to do it.　　We can get ahead of hackers by discovering and closing gaps in detection and visibility before they can be used against us.

Ameya360:ASUKA Taps Exosite and Infineon for CO2 Monitoring Cloud System

　　ASUKA Autotronics & Smart Sensing Inc. has cooperated with Infineon Technologies and Exosite to launch its Indoor CO2 Monitoring Cloud System, which is targeted at smart buildings, industrial workplace monitoring, smart agriculture, and other related use cases. The solution helps enterprises to swiftly establish an indoor air quality monitoring system that meets the Environmental Protection Administration (EPA) regulations, and add value to the system integrators’ IoT service.　　Carbon dioxide (CO2) is a colorless and odorless gas emitted by human activities. It is the most critical indicator of indoor air quality. The CO2 level of outdoor fresh air is around 400 ppm, while the CO2 level of a well-ventilated office is about 600-800 ppm. If people are exposed to high CO2 levels (more than 1000 ppm) for a period of time, the CO2 itself can cause headache, dizziness, nausea and other symptoms.　　Governments around the world are developing ventilation guidelines and regulations that should maintain a comfortable environment (such as schools, hospitals, shopping malls, working facilities, etc.) for most occupants. Taiwan EPA framed the “Indoor Air Quality Management Act ” that regulates certain premises owners to measure, announce, and keep records of CO2 concentration for inspection every two years.　　ASUKA leverages Infineon and Exosite　　ASUKA KP-201 is a high-sensitive, system-level CO2 sensing module by utilizing Infineon’s PAS technology CO2 sensing IC, microcontrollers, and Wi-Fi. It is capable of measuring the indoor air quality every minute and uploading the sensor data via Wi-Fi to Exosite’s ExoSense, a condition monitoring cloud application that provides visualizations and operational insights. The IoT data is securely stored in Exosite’s IoT software platform and can also be accessed by ASUKA mobile APP.　　“We have made the two important things, CO2 sensing and cloud data processing, easier,” said Dr. Ron Hu, President of ASUKA Autotronics. “Because ASUKA’s system-level CO2 sensing module KP-201W has been successfully integrated with Exosite ExoSense and other well-known public cloud platforms, its sensing data can be easily and quickly sent to the cloud without editing any code, achieving a painless plug-n-play IoT system.”　　The next step　　Hu said that the next product will be a system-level module integrating Infineon’s CO2 sensing IC and 60GHz mmWave radar sensor. The mmWave radar can capture subtle movement of people and vehicles. It can be used in smart homes, smart buildings, security monitoring etc. Thanks to its low power consumption, mmWave radar can be used to control electronic appliances to achieve the goal of energy saving and environmental sustainability. The new product will be also compatible with Exosite ExoSense condition monitoring cloud application.

Ameya360:Global Smartphone Shipments Down 12% in 2022

　　The global smartphone market remained under pressure in the fourth quarter (4Q 2022) with shipments declining by 18% year-on-year (YoY) to the lowest level for a holiday quarter since 2013, even as they grew by 1% quarter-on-quarter (QoQ) to 303.9 million units, according to the latest research from Counterpoint Technology Market Research’s Market Monitor service. Shipments for the full year 2022 also declined to 1.2 billion units, the lowest since 2013.　　“The war in Ukraine, inflationary pressures, economic uncertainty and macroeconomic headwinds kept the consumer sentiment weak in 2022 while smartphone users reduced the frequency of their purchases. The smartphone market remained under pressure in the fourth quarter of 2022 as the cost-of-living crisis, shortage in the labor market and a decline in consumers’ purchasing power resulted in double-digit declines in the shipments of each of the top five smartphone players,” said Senior Analyst Harmeet Singh Walia.　　Consequently, global smartphone revenue and operating profit also saw a decline, although to a lesser degree than in shipments. An increased mix of premium phone offerings by major OEMs drove up the overall average selling price (ASP) by 5% YoY in 2022. The 9% decline in revenue, while lower than in shipments, resulted in annual smartphone revenues amounting to $409 billion, the lowest since 2017. A larger decline was prevented by a 1% growth in Apple, the only top five smartphone OEM to do so.　　“Having proficiently managed its production problems, Apple was able to weather a year already marred by economic and geopolitical turmoil better than other major smartphone players. Its iPhone Pro series continued performing well and its share of iPhone shipments could have been even higher if not for the production issues caused by the COVID-19 breakout at the Zhengzhou factory, which produces the vast majority of Pro series volumes. As a result, some Pro series volumes got pushed to January,” said Research Director Jeff Fieldhack.　　Consequently, its shipment, revenue and operating profit declined YoY in Q4 2022. However, it outperformed a struggling smartphone market in terms of shipment, revenue and operating profit growth, in turn achieving its highest-ever shares of 18%, 48% and 85% in these metrics respectively, in 2022.　　Apple also benefited from the premium segment, its primary constituency, being less severely affected by the economic and geopolitical uncertainties that marred the year. Moreover, mature smartphone users are now choosing premium devices that last longer.　　Elaborating on the ‘premiumization’ trend, Research Director Tarun Pathak said, “premiumization can also be seen within the Android ecosystem and is being led by Samsung with its foldable smartphones. As a result, Samsung was the only top five OEM besides Apple to see a 1% growth in revenue, even though its shipments declined by 5% in 2022 and operating profit declined by 1%. The performance of its flagship smartphones was stronger than market projections. Nevertheless, with a smaller profit decline than the overall smartphone market, its operating profit share increased slightly to 12% in 2022.”　　Chinese smartphone players suffered from domestic lockdowns for much of the year in addition to facing global economic and geopolitical difficulties. As a result, the shipments of Xiaomi, OPPO* and vivo fell by more than 20% each. Despite offering premium phones at aggressive margins, Chinese brands are yet to make headway in the premium market and have not been able to capitalize completely on Huawei’s decline. Unsurprisingly, then, their revenue as well as operating profit saw double-digit declines.　　Counterpoint Research expects the market to remain under pressure until the end of the first half of 2023 and to start recovering thereafter.
