windows 10 display stretched after update

LCD mainly includes TFT, UFB, TFD, STN and other types of LCD. The structure of LCD is to place liquid crystal in two parallel glasses. There are many vertical and horizontal small wires between the two glasses. The direction of rod crystal molecules is controlled by power on, and the light is refracted to produce a picture.   High brightness, The higher the brightness value of the array LCD, the brighter the picture will be without blurring. Advanced display can display clearer and higher brightness product features. We rely on polarization filters and light itself. With the practice of natural light in all corners of the world, a series of liquid crystal filters must be parallel.   The higher the contrast, the more colorful and saturated the color will be, and the higher the plane will be. On the contrary, the color change is low, the color display is poor, the image will be flattened, and the color change value is different, even higher. Compared with CRT imager, LCD dot matrix LCD display has the advantages of zero radiation, low power consumption, small heat dissipation, small volume, accurate image recovery and high character visualization.   The view of “big view” simply means that the view in front of the screen can be seen the larger the sight distance, the easier it will be; As long as the viewer changes the viewing position slightly, the picture may become blurred.

The ultra-narrow LCD splicing screen is based on pure hardware and adopts parallel high-speed graphics processing technology to realize the unified processing of multiple high-speed video signals, fundamentally replace the plug-in splicing controller, and solve the problem of limited VGA signal input. Clarity, brightness, and color saturation are three important performance indicators of liquid crystals. The ultra-narrow-edge LCD splicing unit has the characteristics of high definition, high brightness, and high color gamut. Because the LCD uses backlight tubes as the light source, the edges are generally wide. The 40-inch ordinary LCD screen has a margin width of more than 11mm. If used for splicing, the splicing gap should be at least 22mm, which will affect the visual effect. The LCD splicing wall adopts a liquid crystal screen with a narrow-edge structure design, and the edge is reduced by more than double, which does not affect the visual effect when used for splicing. The LCD splicing screen has ultra-narrow edges, the number of splicing can be selected arbitrarily (row (m) X column (n)), and the size of the screen also has a variety of options to meet the needs of different use occasions. The ultra-narrow edge of the LCD splicing screen can be customized according to the requirements of different users, and you can choose functions such as single-screen display, full-screen display, and arbitrary combination display. In view of the inconsistency of parameters between the LCD screen and the driving circuit of the LCD splicing screen, the Tianjin LCD splicing screen

With the vigorous advancement of the country’s new infrastructure during the “14th Five-Year Plan” period and the development of the contactless economy in the post-epidemic era, enterprises, governments, transportation, education, medical and other fields will accelerate intelligent and digital transformation, and smart display terminals have become an industry An indispensable basic carrier in digitization. As the application scenarios of smart commercial display become more and more extensive, its industrial value is constantly improving, and it has become an important strategically significant field in the electronic information industry. As an important part of the LED display, it is natural to not miss this blue ocean market with unlimited prospects. Two commercial display products, digital signage and LED advertising machine, have occupied most of the outdoor commercial display market share in recent years. In today’s market, digital signage is dominated by outdoor commercial display, mainly LCD, and the current LED outdoor advertising machine is also a commercial display product that has only gradually emerged in recent years. Why did digital signage come into being? LCD or LED? Along with the development trend of digital information technology, commercial offices such as merchants, enterprises, and units have already begun to switch to digital propaganda. Traditional posters, leaflets, banners, etc. have all begun to show a substantial reduction, as there are many digital devices that can replace them, and the effect is even better. In today’s day when digital information becomes normal, digital signage has come into life, and the work of publicity and display
