Big screen design

For different uses and display occasions, different large-screen solutions are usually required, and the number of large-screen screens and detailed control system solutions need to be designed according to the number of signal sources and the size of the site. However, there are also many mainstream large-screen technologies, including LCD, LED and DLP, which are based on different lighting technologies and extend to different large-screen products. They have different display effects and specific applications. Therefore, when designing a large screen solution, we must first consider these objective factors, such as what environment the large screen is installed in, whether it is indoor or outdoor, whether it is used to display computer signals or video surveillance signals, or big data signals, the whole occasion. The distance of viewing the large screen, whether it needs to be turned on continuously, etc., all affect the choice of the large screen. Therefore, the design steps of the whole large-screen solution can be divided into the following steps: one is to clarify the display needs, the other is to understand the objective factors and the installation environment, the third is to choose which large-screen product, and the fourth is to use which control system

1. Obvious display requirements and uses First of all, we need to know what our big screen is mainly used to display, whether to display video surveillance for command and dispatch, or mainly to display computer signals for data analysis, for the overall display effect What are the requirements, whether the split screen is mainly used or the full screen is mainly used to display a large screen, which will directly affect the choice of a large screen. For example, the large-screen solutions we mainly use to display monitoring signals are mostly LCD splicing large screens. If it is based on full-screen display, compared to tracking the effect of the whole screen, so many LED large screens are used. 

2. Understand the objective environment and size Second, the environment and size of the installation location are different, and the large screen solution selected is also different. Whether it is installed outdoors or indoors, the length and width of the installation size will directly affect the choice of large screen. If it is installed outdoors, then the large screen solution can only use LED large screen, because only it is waterproof and sunscreen. If it is used indoors, then it is necessary to design the splicing number of LED large screen modules and cabinets according to the length and height of the installation location, as well as the splicing number of LCD large screens, etc. This objective condition will directly affect the large screen solution. number and the size of the installed display area.

3. Choose which large screen to use There are three common large screens at present, one is LCD splicing large screen based on LCD display technology, one is LED large screen, and there is a DLP large screen, but now DLP large screen The cost-effectiveness of DLP is not particularly high. With the introduction of large LCD screens with small seams and large LED screens with small spacing, the use of large DLP screens is no longer mainstream, and the cost performance is also slightly average, so we mainly use LCD large screen solutions. And the LED large screen solution is the main choice. The LCD large screen is characterized by high-definition, good stability, and supports 24-hour boot operation. It looks like a TV. It forms a large-size screen by splicing multiple screens. It can display high-definition film sources, so it is especially It is suitable for monitoring and display purposes, but it will have a physical border at the splicing point, so that it will have a slight visual impact when displaying images in full screen.

4, control processing system a full screen design in addition to the screen, but also involves the composition choice and control processing system, because, according to the big screen only responsible for the implementation which display effect and the function or by joining together to achieve the control of the processor, depending on the type of big screen used by the control device is also different, such as in the LCD screen If it is used to display surveillance video signals, then the control system may use a decoder, and if it is used to display computer signals, then it may use a distributor or matrix. And if it is used for LED large screen display system, then the control system uses the image processor, because the LED module and module itself can not be spliced, so it needs the image processor to achieve the picture splicing display. A full screen program consists of four parts, so should not only know how big the screen design, but also know their own according to need, in order to choose the corresponding screen, and the objective environment factors, we know that if the planning in the design of scheme of splicing number and display area, but also depending on the type of signal source with a big screen choose well control equipment, in order to realize the picture Smooth display and achieve the corresponding display function.
