B[The international standard for raster scanning laser displays led by China is officially released] On November 10, we learned from the National Standards Committee that the International Electrotechnical Commission (IEC) recently officially released the international standard "Laser Display Part 5-8: Scanning Characteristics Test Method for Raster Scanning Laser Displays". The standard is jointly developed by Chinese experts as project leaders and experts from Belgium, the United States, Japan and other countries. Raster scanning is one of the main technical routes for laser display. Common products include micro laser projectors, AR/VR displays (augmented reality displays and virtual reality displays), etc. Raster scanning is like using a very thin "laser paintbrush" to draw on the screen: through a small mirror that swings quickly, the laser beam is controlled to move up, down, left, and right to scan out the complete picture.
This standard stipulates the test conditions and test methods for the main characteristics of raster scanning laser display devices such as scanning linearity, scanning repeatability and waviness, as well as the reporting form of test results. It provides reliable technical support for product development, manufacturing and quality evaluation, and is conducive to improving the comparability of test results between different products and different testing institutions. Raster scanning laser display is a key pixel engine that supports the expansion of human-computer interaction applications such as AR/VR and vehicle-mounted light fields. China has taken the lead in condensing the results of independent technological practices into international standards, which has a positive effect on the future development of the laser display industry and is an important step in the development of China's core laser display technology field. A[Overview of U.S. stock market pre-market news: NVIDIA increases stock repurchase authorization by US$150 billion; NVIDIA launches a two-layer AI security system to prevent robots from losing control; TSMC’s 2nm chip monthly production capacity may reach an unexpected 120,000 pieces by the end of the year] September 28th, investors need to focus on the following financial news from the U.S. stock market:
1. Futures on the three major U.S. stock indexes fell collectively. Dow Jones futures fell 0.50%, S&P 500 futures fell 0.39%, and Nasdaq 100 futures fell 0.67%.
2. International oil prices rose collectively. WTI crude oil futures prices rose 3.02% to US$95.202/barrel; Brent crude oil futures prices rose 2.48% to US$99.857/barrel.
3. International gold and silver spot prices both plummeted. Spot gold prices fell 3.13% to US$4,151.09 per ounce; spot silver prices fell by 4.59% to US$61.35 per ounce.
4. The three major European stock indexes rose moderately. Britain's FTSE 100 index rose 0.46%, France's CAC40 index rose 0.49%, and Germany's DAX30 index rose 0.18%.
5. Nvidia’s board of directors approved an increase in the stock repurchase plan by US$150 billion, bringing the total to US$235 billion. The repurchase plan is expected to be implemented before fiscal year 2028.
6. NVIDIA provides double-layer security protection for AI agents through two open source software tools, OpenShell and Nvidia Sentry. OpenShell can run on the NVIDIA Vera CPU to limit the access rights of AI agents in real time; Nvidia Sentry can monitor the behavior of the agents and isolate them when abnormalities are found, which can be completed within a few milliseconds at the fastest.
7. Nvidia CEO Huang Jen-Hsun will meet again with Samsung Electronics Chairman Lee Jae-yong and SK Group Chairman Choi Tae-won in New York on the 28th local time. HBM is the topic of greatest concern to the industry at this meeting.
8. Qualcomm is developing semiconductor chips for wearable devices, including smart glasses, augmented reality/extended reality (AR/XR) devices, smart watches, etc. Key products include Snapdragon AR and XR.
9. Samsung Electro-Mechanics announced an investment of 4.27 trillion won to expand packaging substrate production facilities to expand packaging substrate production capacity. The project is located in Sejong Factory, South Korea.
10. As major customers such as Apple, Nvidia, and AMD have increased orders by 10% to 20%, TSMC is accelerating the expansion of its 2nm production capacity. It is reported that monthly production may reach 120,000 pieces by the end of the year, higher than the previous market estimate of 90,000 to 100,000 pieces.
11. OpenAI is reported to be stepping up preparations and will soon launch a resident AI assistant named "o" to compete head-on with Meta Muse.
