How to adjust the proportion of small-pitch LED large screen?
Many times, when we are designing small-pitch LED large-screen solutions, due to the limitations of the installation environment, the display ratio of the large screen cannot be designed according to the conventional ratio of 16:9, such as monitoring centers, exhibition halls, conference halls and other occasions. The height is limited, and the width is generally longer. If the user wants to make a large screen, the conventional splicing ratio is often unable to meet people's needs.
Here, many customers want to choose unconventional splicing methods such as 3x5, 3x6, 4x6, 4x8, etc., which causes the large-screen display to not meet the 16:9 ratio. If used to display information such as pictures, documents, videos, etc., it will be deformed and stretched. In response to this situation, our company has launched a point-to-point, non-deformation display solution, which can achieve non-deformation display on the small-pitch LED large screen with unconventional proportions, and achieve a better visual experience. Because our output computer monitor is basically 16:9, when the entire screen is placed on a large screen, the entire image will be stretched. Therefore, our company has developed a built-in multi-screen splicing processor that can connect a computer and a large screen, and evenly distribute the resolution to each screen. Each processor supports a maximum resolution of 3840*2160. The greater the number of screens, the greater the number of processors, and the number of processors can be increased. Each large screen is connected with an HDMI cable, so that each screen has a resolution.
LED vertical screens are mostly used in some exhibition halls, such as corporate exhibition halls, 4S shops, science and technology museums, etc. Because they are all viewed at close range, the line of sight is basically head-up, and the width is relatively long, so many users will think of using a row of vertical screens Installation, at this time, it is difficult to maintain the proportion of the large screen after splicing. If we project the content of a computer onto the entire screen, it will be severely deformed. At this time, a non-deformation solution can be used.
Special-shaped screens are mainly used for some special occasions, such as creating themed display areas or areas corresponding to the decoration style, such as the Expo Hall and the Party History Exhibition Hall. At this time, the arrangement of the large LED screen is irregular, as shown in the figure below. At this time, we cannot use a computer to control the screen, but can only use a solution that does not deform.
At this time, many users think that the resolution of a single screen is 1920*1080. If multiple screens are used for stitching, will the resolutions overlap? The answer is impossible, because the maximum output resolution of our traditional HDMI high-definition cable is only 4K, and images exceeding this resolution will be blurred. Although it can remain undistorted, the display effect is relatively poor. At this time, only point-to-point non-deformable big data display solutions can be used to meet the demand.
