The development of display device technology has always been the main driving force for the development of the audio-visual market. This is not unrelated to people's constant pursuit of clearer, larger vision and more realistic images.
Looking back at the world's major consumer electronics and audio-visual technology exhibitions this year, many display technologies have made breakthroughs, including naked-eye 3D technology has broken through the limitations of size and viewpoint, bringing a lot of practical products; laser light source also started Entering display device applications, hybrid laser light source with LED has broad application prospects; active and polarized 3D glasses technology has fully covered mainstream flat-panel TVs and home theater projectors; 4K2K flat-panel TVs and home theater projectors are gradually moving toward Home market and so on.
However, if only the display device gains a technological breakthrough and the signal source fails to keep up with it, I am afraid it is just empty talk. In particular, the current 4K2K and 3D program sources are far from meeting the market demand. Therefore, the corresponding video processing technology came into being - 4K2K up-conversion and 2D-to-3D processing.
4K2K up-conversion technology can up-convert 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 3D stereo image. In fact, these two technologies have been widely used in the commercial field, and the technology is quite mature. Therefore, in the latest launch of many new cameras, these two processing functions are built in, which solves the compatibility problem in the signal source. The following will be the author's incomplete interpretation of these two new technologies and products, so that everyone can step into the latest display technology field.
I believe that audio-visual enthusiasts will know that 1920×1080 is the physical resolution of the current mainstream HD display devices, and the physical resolution of the 4K2K flat-panel TVs recently shown at major exhibitions is twice that of 3840×2160. However, there is an exception here. The VPL-VW1000ES home theater projector from Sony is 4096×2160. In fact, both belong to the category of 4K2K, the difference is that the former is the household standard, and the latter is the DCI digital cinema standard. When playing the current mainstream 2.35:1 specs, there is no significant difference between the two.
It is worth noting that the 4K2K up-conversion processing technology mentioned here actually refers to converting the 1920×1080 level full HD signal source into 3840×2160 level image through advanced pre-interpolation technology. Many users who have experienced 480p up to 1080p may doubt whether this non-native 4K2K picture can reach the available range. After all, the picture from standard definition line to full HD is far from the original full HD picture. In fact, the birth of 4K2K up-conversion technology is not to make the full HD signal source output image as clear and delicate as the original 4K2K signal source on the 4K2K display device, but to enhance the display effect of the full HD signal source on the 4K2K device. Beyond the effects on 1080p devices.
Recently, many new home theater projectors have been launched on the market, such as the world's first civilian-grade 4K2K projector VPL-VW1000ES brought by Sony. In fact, Sony developed the 1.55-inch 4K2K SXRD chip in 2004, and then applied it to commercial-grade projectors. This year, through technical design changes, Sony developed a new 0.74 inch 4K2K class SXRD chip, the precision between the pixels reached an astonishing 4μm, so that the overall size of the projector can be reduced to the level of ordinary home theater projector, thus promoting The birth of the VPL-VW1000ES projector.
The typical Electrical Wire harnesses that ETOP supplies include dozens of wires and sometimes hundreds of different components and terminations. Our engineering staff is well versed in the design and construction of wire harnesses and is available to assist in the development of the most efficient wiring harness to meet your demands. A basic Wire Harness may include as few as three discreet components, while the more classic harnesses include many more wires and other passive, and potentially active, components.
