The development of display equipment technology has always been the main driving force for the development of the audio-visual market. This has something to do with people's continuous pursuit of clearer, larger vision and more realistic images. Looking back at the major consumer electronics and audio-visual technology exhibitions around the world this year, breakthroughs have been made in many display technologies, including naked-eye 3D technology, which has broken through the limitations of size and viewpoint and brought many very practical products; laser light sources have also begun In the application of display devices, hybrid laser light sources with LEDs have broad application prospects; active and polarized 3D glasses technology has fully covered mainstream flat-screen TVs and home theater projectors; 4K2K flat-panel TVs and home theater projectors are also gradually moving towards Home market and so on. However, if only the display equipment has achieved technological breakthroughs and the signal sources cannot keep up in time, it may be just empty talk, especially the current 4K2K and 3D program sources are far from meeting the needs of the market. As a result, the two corresponding video processing technologies came into being-4K2K upscaling and 2D to 3D processing. 4K2K upscaling technology can upscale the current mainstream 1920×1080 physical resolution signal source to 4K2K ultra-high-definition accuracy, while 2D to 3D technology can convert any 2D planar image into a 3D stereoscopic image. In fact, these two technologies have been widely used in the commercial field, and the technology is quite mature. Therefore, these two processing functions are built-in in many of the most eye-catching new machines launched recently, which solves the problem of compatibility in signal sources. The following will be the author's incomplete interpretation of these two brand-new technologies and products for everyone, so that everyone can enter the upcoming field of the latest display technology first. I believe that audio-visual enthusiasts will know that 1920×1080 is the physical resolution of current mainstream full-HD display devices, and the physical resolution of 4K2K flat-panel TVs recently displayed at major exhibitions is twice that, reaching 3840×2160. But there is an exception here, the VPL-VW1000ES home theater projector brought by Sony is 4096×2160. In fact, both belong to the category of 4K2K. The difference is that the former is a household standard, and the latter is a DCI digital cinema standard. When playing the current mainstream 2.35:1 movie blockbuster, there is no obvious difference between the two. It is worth noting that the 4K2K upscaling technology mentioned here actually refers to converting a 1920×1080 level full HD signal source into a 3840×2160 level image through advanced pre-interpolation technology. Many users who have experienced upscaling from 480p to 1080p may wonder whether this non-native 4K2K picture can reach the usable range. After all, the picture from SD to full HD is far from the original full HD picture. In fact, the birth of 4K2K upscaling technology does not allow the picture output by the full HD signal source to be as clear and delicate as the native 4K2K signal source on the 4K2K display device, but to enhance the display effect of the full HD signal source on the 4K2K device. Go beyond the effect on 1080p devices.
