Analysis of the four major conference room display devices, how should we choose?
With the advent of the intelligent information age, not only has it changed people's living habits, but it has also ushered in changes in enterprises. With the abundance of display devices, the choice of display systems has become diversified, and with it, multimedia conference display With the advent of the intelligent information age, not only has it changed people's living habits, but it has also ushered in changes in enterprises. With the abundance of display devices, the choice of display systems has become diversified, and with it, multimedia conference display systems have also ushered in many technical innovations. In modern conference room equipment, usually equipped with a set of conference display control system for conference display, video conference, staff training, business reception, etc., bearing an important corner of the company's daily activities. Large screen displays are also becoming more and more popular in indoor conference displays, with HD, UHD, large size, and networking being what users are looking for. Here, some users may not quite understand when choosing a large screen in the conference room, which display is better to use, let me analyze the characteristics of these products, I hope to provide some help to you.
In the past, LED displays were commonly used for outdoor large screen displays. In recent years, with the introduction of small-pitch LED series, it has also started to be used in conference room occasions. Its other applications are: outdoor commercial display, publicity display, stage large screen, etc., all using LED display, and in the application of conference occasions, generally using small-pitch LED display, but basically in the area of a larger space, such as the lecture hall, conference hall, auditorium and other occasions. It has significant advantages, no stitching, the entire screen without display barriers; screen size arbitrary splicing, so the display area is larger; higher resolution, ultra-small screen pitch can be achieved 0.9mm, already close to the LCD display technology, so there is a better visual experience when displaying video or images in full screen. However, LED display also has some disadvantages, such as slightly lower resolution, close viewing mosaic, there is a certain impact on the display effect; easy to damage, over time there will be part of the area is not bright, which will greatly improve the after-sales maintenance rate.
Intelligent conference all-in-one can be understood as an upgraded version of large LCD TV, a new type of conference display products, ranging in size from 55 to 110 inches. It also has Android or windows system, which can be used as a computer or as a tablet. Large LCD TV its characteristics are single screen size, full HD display 4K, no splicing, intelligent conference all-in-one machine in addition to the previous advantages also has a touch function, can be directly handwritten, to achieve the function of display writing all one, simple and fast operation, intelligent conference all-in-one machine / large LCD TV more suitable for small and medium-sized conference rooms; because they are more flexible and convenient to use, mobile bracket support at any time to move, can Touch whiteboard writing, can video conferencing, etc. The disadvantage is that the screen size is limited, can not be spliced, and can only access an input signal source.
I believe we all know about the projector, or have used it, by projecting the display.
Its advantages are: low price, currently affordable a conference screen display products; easy to install, directly hang the projector, hanging curtain to put; curtain can be put away, does not take up space. Disadvantages: curtain restrictions, size fixed, can not be spliced, can only be used in small conference rooms, in a slightly larger occasion back row of people can not see the content on the screen; screen brightness is low, you need to turn off other light sources to ensure darkness in the space, turn off the lights to display the effect is good; low contrast, resulting in color is not rich enough; low resolution, the screen will not feel clear; signal source single, only one input signal.
In recent years, with the continuous improvement of the seam technology, the seam is getting narrower and narrower, from the past large seam to 3.5mm, 1.8mm, 0.88mm. LCD splicing screen physical black edge is very small, the screen display is basically not affected by the seam. The advantages of the splicing screen are: according to the size of the indoor space to design the screen display size; multi-signal source input, multiple computers can access the conference screen, while on the screen display image; high brightness and contrast, rich color; high resolution, clear picture. It has been widely used in many indoor areas, of which the conference occasion is a big application area. Its disadvantages are: conventional LCD splicing screen has a certain splicing gap, that is, the black edge impact, if viewed at close range on the whole visual effect will have some impact.
To achieve the perfect splicing screen effect will need a video wall splicing processor.
BIT-VWC-409R is an industrial-grade high-performance high-definition video wall controller LCD video wall processor based on FPGA processing technology, which can realize various splicing modes within 9 screens, support multiple devices parallel use, 4*HDMI/1*DP inputs, 9*HDMI outputs, PIP mode. Single output resolution supports 1080P60Hz. Full hardware real-time processing architecture, pixel-to-pixel, no deformation, no stretching, no software control required, plug and play, or according to customer needs to customize display mode. Use in the conference system can be adjusted according to the number of input sources at any time the splicing mode of the screen, more convenient to improve efficiency.
At present, the display screens applied in conference rooms are basically the above four types, and we need to choose the corresponding products according to our actual usage requirements.
