October 22, 2002, the company Sharp has announced a technology of forming chips on a glass substrate, called CG Silicon Technology (CGST). On this day, demonstrated the prototype of the legendary 8-bit CPU Z80.
Technology CGST (Continuous Grain Silicon, silicon with a continuous crystal structure) allows for the glass substrate of the LCD screen to mount all related piping display. These include voltage regulators, and control circuits, and interfaces. As an example, the viability of the technology have been demonstrated a prototype display with an integrated 8-bit Zilog Z80 CPU, which consists of 13 000 transistors. Next year the chip will be 40 years old.
According to the developers, the technology CGST capable of providing three times faster response time than ordinary structure on the polysilicon of the time. It was planned that the first commercial glass panels will appear first in mobile phones and PDAs, and later on in monitors and televisions. In October of the same year, Sharp began mass production of LCD panels integrated in electronic substrate binding, called System LCD.

On October 22 2009 , Microsoft released operating system Windows 7. Previous OS — Windows Vista was a failure. The theory, according to which the success of Microsoft releases bad, once again confirmed.
The main change in Windows 7 is the new taskbar, which globally has not been modified since the days of Windows 95. Even in Windows Vista it is not much different from the first embodiment. In Windows 7, the company decided to make the task bar more adapted to the modern requirements. In the seventh, it resembles a hybrid of its predecessor Windows Vista, as well as the Dock from Mac OS X.
The release of Windows 7 marked the beginning of DirectX 11 era, the most popular API in use today. Along with the new at the time software interface introduces support for tessellation, multithreaded rendering, and the calculated Shader (Compute Shaders), which allows to simplify work with GPGPU-computing.
In General, after a few years we can safely say that Windows 7 has become a kind of mistakes. Is highly successful. “Seven” for all parameters was better than Windows Vista.
Following the Windows 7 Oct 26, 2012 Microsoft released Windows 8 operating system. A year later, Windows 8.1. In 2015, there appeared Windows 10. As you can see, the release of new revisions of operating systems Microsoft shares on average 2-3 years. “Eight” received a ton of criticism due to the failure of developers from the classical menu “start”. Instead, it appeared the “active corner”, clicking on which opens the start screen and the unfriendly interface called Metro. In Windows 10, which is not surprising, “start menu” back. It allows the user to simultaneously view a list of the most used programs and files, and configure applications, online resources and contacts. View, will be whether “ten” is more popular than Windows 7. If you believe the statistics by Microsoft, then to 19 January 2012, it has sold over 525 million copies of this operating system.

22 Oct 2012 industry organization Consumer Electronics Association (CEA) adopted the name and the minimum features Ultra HD (Ultra HighDefinition). It happened by anonymous voting of the Council working group. Recall that the Ultra HD there is another name — 4K. Plus the Korean company is trying to promote another marketing name — SUHD.
So modern and Ultra HD projectors, monitors and TVs must have at least 8 million active pixels: at least 3840 horizontally and at least 2160 vertically. The aspect ratio should not be less than 16:9. Plus the device needs to have at least one digital input capable of receiving a video signal with a resolution of 3840×2160 pixels. It turns out that the resolution of Ultra HD is four times Full HD.
The aspect ratios of popular standards
