Electronic enthusiasts eight o'clock: According to foreign media reports, Apple seems to have quietly built a research institute in Switzerland, which may be related to the company's self-driving car project. According to the Swiss local website Inside-IT this week, at least 10 doctoral students and postdocs have left the Zurich Institute of Technology (ETH Zurich) to enter Apple's research institute. It is said that Apple especially needs talents with rich experience in computer vision and robotics. Most of the talents it recruits focus on the field of visual navigation. It is said that Apple refused to comment on the matter. Roland Siegwart, a professor of automation systems at the Zurich Institute of Technology, told Inside-IT that his five experts have moved to multinational companies, but he is not sure whether the Apple Swiss Institute really exists. Apple usually publishes news when it opens a new international research institute, but sometimes it may remain silent in order to avoid being concerned about the outside world, especially when it comes to new products. For example, last year it was reported that Apple opened a secret car lab in Berlin; in fact, Apple's car project has long been exposed, because AppleInsider found a subordinate in Sunnyvale, not far from Apple's Cubertino headquarters. Laboratory for Apple and related to automotive projects. Apple called its car project "the Titan Plan" and it is not clear how the project is going. Although the outside world was convinced that Apple intended to develop a complete car product, it was said that it later changed its plan and focused only on the automatic driving system. Apple may decide to design a car or cooperate with other car manufacturers later this year. Recently, Didi traveled to open a self-driving car lab in Mountain View, California. Apple invested $1 billion in the company last year.

VGA, or Video Graphics Array, is a standard for Video transmission using analog signals. Early CRT displays could only receive analog signal input due to design and manufacturing reasons, so the video card inside the computer was responsible for digital-to-analog conversion, and the VGA interface was the interface for the output of analog signals on the video card. Today, LCD monitors can receive digital signals directly, but in order to be compatible with VGA interfaces on video CARDS, VGA standards are mostly supported.
In VGA video transmission standard, the video image is decomposed into red, green and blue primary color signals. After digital-to-analog conversion, the video image is transmitted in three independent channels under the synchronization of HSYNC and VSYNC signals. The synchronization timing of VGA in the transmission process is divided into line timing and field timing. VGA timing consists of three elements: pixel clock, row field synchronization signal, and image data.
Early VGA specifically refers to the resolution of 640X480 display mode, later, according to the resolution, VGA is divided into VGA (640X480), SVGA (800x600), XGA (1024x768), SXGA (1280x1024), etc. VGA display timing at different resolutions is similar
