In today's conference rooms, large screens are generally used for daily meetings and video conferences. In the past, the main types of large screens on the market were projectors, DLP screens, LCD splicing screens, and full-color LED screens. Among them, LCD splicing screens and full-color LED screens are widely used, and many customers here do not know which one is better. Today, we analyzed the advantages and disadvantages of these two types of large screens, hoping to provide effective assistance to everyone.
Firstly, the reason why most customers choose between LCD splicing screens and full-color LED displays is undoubtedly due to considerations such as resolution, usage scenarios, and budget. As is well known, due to the low brightness and insufficient resolution of projectors, they cannot meet people's needs in many applications. Therefore, it is inevitable that projectors will gradually be phased out in recent years. Although the LDP large screen compensates for the shortcomings of projectors, many customers are unwilling to use it due to its high price. Therefore, in terms of conference display, LCD splicing screens and full-color LED displays are more suitable.
1、 LCD splicing screen
At present, the LCD splicing screens used in conferences are 46 inches, 49 inches, and 55 inches in size. The splicing technology is mostly 0.88mm, 1.7mm, 1.8mm, 3.5mm, or 0mm seamless splicing. Although the single screen resolution of LCD splicing screens is 1920x1080, 4K high-definition display can be achieved through image splicing processors, which is also a choice for many customers; Some customers also want to display big data at higher resolutions, so they must adopt point-to-point big data display solutions to achieve higher resolutions. Currently, 16K ultra clear display technology can be achieved, making the large screen more diverse and colorful
Advantages: Ultra clear display, soft colors
Disadvantage: There are subtle seams
2、 Full color LED display screen
In the past, LED display screens were mainly used for outdoor occasions. For example, we use outdoor light-emitting diode displays in large billboards, which are common in urban warning areas or highways. Because the viewing distance is generally far and the resolution is not high. But with the launch of the small pitch LED series, the resolution has greatly improved and is getting closer to the level of LCD technology. At present, the ultra small spacing technology of P 0.9mm (pixel size of 0.63mm on a 55 inch LCD splicing screen) has been achieved, with very high resolution in conference display.
For the selection of full-color LED display screens, the overall display area and viewing distance of the conference room should be considered first, so as to better design the configuration scheme. In conference rooms, users generally choose models based on viewing distance, and generally use small pitch LED series below P2, such as P0.9/P1.25/P1.53/P1.876, which are full-color LED displays. It is worth noting that the production conditions for ultra small pitch LED P 0.9 and P1.25 are harsh, the process is exquisite, and the cost is relatively high.
Advantages: Seamless splicing
Disadvantages: The resolution is not as good as LCD splicing screens, and the price is also relatively high
In our actual selection, when the price allows, we usually choose based on the size of the conference room space and viewing distance. Small and medium-sized conference rooms (with dozens of attendees) generally use LCD splicing screens; In large conference halls (with more than 100 attendees), it is more appropriate to use full-color LED displays. Overall, both types of large screens have their own advantages, and if you choose, you can decide based on your actual situation.
