In modern conference room design, it is usually equipped with a large display screen. There are four common products: LCD splicing screen, small spacing LED display screen, intelligent conference panel and projector. Due to the different display technologies of these products, the display effects are completely different, and there are also great differences in price, signal, function and so on. Here, some customers may not be very clear when choosing the large screen in the conference room, so which large screen to display is better. Let’s analyze the characteristics of these products and hope to provide you with some help.
1、 LCD splicing screen.
In recent years, since the introduction of ultra narrow edge technology of LCD splicing screen, the seam has become narrower and narrower. At present, 0.88mm ultra narrow edge frame can be realized. At the same time, 0mm seamless splicing technology is introduced, which has a good picture integrated display effect and is widely used in the conference room.
advantage:
1. Design the screen display size according to the indoor space;
2. Multi signal source input, allowing multiple computers to access the conference screen at the same time and display images on the screen;
3. High brightness and contrast, rich colors;
4. Through 4K splicing processor or point-to-point big data display solution, it can achieve high resolution, single screen 1920 * 1080, clear picture and high resolution.
Disadvantages:
The conventional LCD splicing screen has a certain splicing gap, which is affected by the black edge. If you watch closely, you will have some visual impairment. Although there is no splicing in theory, the fusion degree of 0mm seamless splicing screen is generally only about 90%, which is always affected by certain splicing.
Second, small spacing LED display.
Small spacing LED displays can be seen everywhere in our life, such as billboards, publicity screens, large stage screens, etc. All adopt LED display screen; In the application of conference occasions, the LED series with small spacing is generally used, but it is basically used in large-area occasions, such as lecture hall, conference hall, auditorium, etc.
advantage:
1. There is no seam, and there is no display obstacle on the whole screen;
2. The screen size can be spliced arbitrarily, and the display area is larger;
3. High resolution, ultra-small spacing up to 0.9mm, close to LCD technology.
Disadvantages:
1. The resolution is slightly lower than that of liquid crystal technology, and mosaic will appear when you look closely;
2. With a certain after-sales rate, dead lights often appear;
3. High brightness, not suitable for close viewing. It will dazzle you after watching it for a long time.
Third, intelligent conference tablet.
Intelligent conference tablet is a new type of conference display product. If a large tablet computer has both Android and windows systems, it can be used as both a computer and a tablet. Conventional sizes are 65 inches, 75 inches, 86 inches, 100 inches and 110 inches, which are generally suitable for small and medium-sized conference rooms.
advantage:
1. It can be touched. The whole screen is designed as a capacitive screen, which can write with your fingers at will, effectively improving the efficiency of the meeting;
2.4k resolution, better definition;
3. It can be moved, does not need to be fixed in a certain position, and can be pushed to any position at will;
4. Wireless screen transmission and display can be realized by directly using the projector without HD cable connection.
Disadvantages:
1. The screen size is valid and cannot be spliced;
2. There can only be one signal source input.
4、 Projector
I believe everyone has the knowledge of projector, or has used projector and displayed it through projection.
advantage:
1. Current low-cost and economical conference screen display products;
2. The installation is simple, the projector is directly hoisted, and the goods can be delivered after hanging the curtain;
3. The curtain is retractable and does not occupy space.
