(1)Background of the use of the large-screen display in the conference room
What kind of display screen is the best for the conference room large screen? This is a question that many conference display users want to know when building a modern smart conference room. Because there are many large screen products that can be used in conferences, in addition to the traditional ones In addition to projection, it also includes some products based on LCD splicing screens and LED displays, such as LCD splicing screens and LED displays. However, due to different display technologies, each conference room large screen has its own characteristics, both advantages and disadvantages, so the display effects are different, which also affects the large screen products selected in different conference rooms. There are also differences.
At present, there are about four kinds of display screens mainly used in conference room display, namely projection, LED large screen, LCD splicing screen, intelligent conference panel and so on. Which one to use needs to start from the display requirements, such as what the display content is, the viewing distance, including the size of the conference room and the number of viewers. Therefore, we first need to know the technical characteristics of the above four conference room large-screen products, and which conference rooms are suitable for.
(2)Introduction of four kinds of conference room large-screen products
- The advantages and disadvantages of projection and what meeting room is suitable for it
Advantages: Inexpensive; easy to install without too much technicality
Disadvantages: general display effect, easy to reflect light, low definition; limited display size
Projection is the choice of most conference room display screens at present. It is very popular, and its advantages and disadvantages are also very obvious. Its price is relatively cheap among these four large conference room screens, and it does not need to be too professional. Technical knowledge, users can install it themselves. However, the effect of death when displaying images is very general. For example, its low resolution makes the picture not very clear. In addition, the brightness and contrast are low. If there is light or sunlight, you need to draw the curtains to display the effect. , otherwise there will be serious reflections. Furthermore, the function is relatively simple, the projection only supports one computer screen projection, and it cannot realize multi-computer control. So if we have a low budget and don’t pay much attention to the display effect, we can use projection, which is used in many conference rooms of enterprises.
- The advantages and disadvantages of LED large screen and what kind of conference room is suitable for it
Advantages: no splicing gaps: high brightness
Disadvantages: easy to dead lights; poor close-up clarity and easy to glare
LED large screen is currently a widely used large screen product, especially outdoor advertising screens. With the development of small-pitch technology, it has also begun to be widely used as a conference room large screen. The advantage is that it can be spliced into any size, and there is no trace of splicing, the whole screen display effect is very good, and its brightness is relatively high, even if there is light and sunlight, it will not affect the normal display. . However, when it is used in a conference room, the disadvantage is also very obvious, especially its lamp beads often fall off, resulting in individual pixels not lighting up, which will affect the overall picture sense over time. In addition, its resolution is relatively general, even small-pitch products will have mosaics when viewed at close range, and the clarity is average.
According to the characteristics of LED, if we are a large conference room, it can be used in conferences such as lecture halls, because it can take advantage of its good display effect on the whole screen, and at the same time can reduce the influence of its disadvantages.
3.LCD splicing screen and what kind of conference room is suitable for it
Advantages: high-definition display: the picture is soft and textured; stable and reliable, less after-sales
Disadvantage: There are seams
The LCD splicing screen is also gradually applied to the conference room display by professional monitoring display devices, and it is also a high-definition conference room large screen, which can reach 4 displays. At the same time, due to its moderate brightness, it will not be dazzling for long-term viewing. At the same time, it can meet the requirements of indoor display occasions, and it has rich colors and strong contrast, so the overall picture texture feels good. In addition, industrial-grade LCD panels are more durable, and the post-sale rate is very low. However, it will have a seam on the screen when splicing, which will affect the integrity to a certain extent.
If we are a medium-sized conference room, the number of participants is about 30, and the viewing distance is relatively close, it is more suitable to use the LCD splicing screen as the large screen of the conference room, especially in our conference room There are many computers that need to be connected to the conference room. When the screen is displayed, it can switch and distribute the signal very well.
4.What kind of conference room is the smart conference tablet suitable for?
Advantages: 4K HD: Touchable: Removable; Dual System
Cons: Limited screen size, up to 110 inches
The smart conference board is a large-screen product specially developed for conference rooms. It is also based on LCD technology. It has a higher distribution rate and can directly play 4K signals. At the same time, it can also be touched, just like a tablet. Like a computer, we can use our fingers to operate live broadcasts, and the whole is more intelligent. It can cast images on the computer, and can realize wireless screen projection. In addition, the death itself is also a computer, which can directly access the Internet and store it. Furthermore, it can move the position, and does not need to be fixed in one place. It is a large-screen product for conference rooms that is more flexible at present. However, its screen size can only be up to 110 inches at present, and it cannot be spliced, so it is only suitable for use in small conference rooms, and the number of viewers is preferably less than 10 people.
(3)Summary
The above four are several conference room large-screen products with high usage rate. There is no unified standard answer as to which one is better to use, because each large-screen has its advantages and certain limitations. Which one to use depends on our purpose, the size of the conference room, and our budget. For example, when we have a low budget, we can use projection as a large-screen display in the conference room. If we pursue clarity, we can focus on LCD technology. If it is a large-scale conference report, we can consider LED large screen.
