In order to achieve satisfactory TV results, how to select and use DLP splicing screens?

   1. The stitching gap should be as small as possible

      The effect of the background display we want on TV is seamless. This requires that the gap of stitching is small enough so that the gap cannot be seen from the lens. At present, the use of titanium needle stitching technology can reduce the stitching gap to less than 0.2 mm. At the same time, the connection plate design can ensure that the screen does not deform during thermal expansion and contraction.

    2. Color temperature needs to be adjustable

        Like the LED display, the color temperature of the DLP splicing screen needs to be consistent with the color temperature of the light in the studio to ensure the true reproduction of the image color.

    3. Studio lighting needs to be well controlled

       Compared with other display screens, DLP splicing screens have relatively low brightness. This requires controlling studio lighting to avoid direct light on the screen. After researching, we used cold light source lamps with a 20 ° grille to effectively control the illuminance of the light hitting the screen within 100 lux, and also ensured that the illuminance of the host's face light can reach 800-1000 lux, which was satisfactory Effect.

    4. Higher uniformity

       DLP splicing screens are formed by splicing multiple displays, which also results in individual differences between each screen. We want them to look like a large display with matching colors and brightness. This requires technical means to improve Uniformity. At present, this technology is relatively mature. Advanced technology manufacturers have been able to run in the background in silent mode without operator involvement. It integrates a proprietary brightness and color sensor to continuously measure the color and brightness of the screen wall and transfer it between projection modules. Communication, automatically matching all white, all black and all gray levels of brightness and color of all display modules, and keeping the gray level of the entire display the same, thus achieving long-term consistency of images under multi-screen stitching

    5. The light source needs to have high security

       The live broadcast of TV is becoming more and more interactive, and the security requirements of the background are also getting higher and higher. The single screen size of the DLP splicing screen is larger. If there is a problem with the light source, it will cause a black screen. The impact will be great. Therefore, a dual-lamp hot backup or a redundant LED module is required as the light source.

    6. Ensure good heat dissipation and control noise

       UHP bulbs and LED light sources generate a lot of heat during work. Its heat dissipation is an important link to ensure the life of the light source and normal work. Advanced liquid cooling technology can make cooling efficiency higher, noise is lower, and you must pay attention to maintaining good The ambient temperature cannot be cut off immediately when the power is turned off. The cooling system should continue to run for a period of time to allow the light source to fully cool before turning off the power. This protects the light source and allows it to work optimally which performed.

       DLP splicing screen is a major change in the background of the studio, but because of its higher requirements for lighting, it is not suitable for use in large-scale variety shows, suitable for news, interviews, live connections, weather forecasts, etc. in small and medium-sized studios Type of show.

       With the development of technology, there will be more new technologies and new ways applied to the studio background. We must understand their characteristics in depth, and choose technical products as backgrounds based on different studio conditions, program formats, and requirements, so that these new technologies can maximize their advantages, better serve the programs, and serve the audience.
