Nowadays, when decorating multimedia lecture halls in many government, school, hotel, enterprise and other units, the application of large display screens is generally considered. There are many display devices suitable for multimedia lecture halls, such as projectors, conference all-in-one machines, LCD splicing screens, LDP large screens, LED display screens, etc. Among them, LED display screens and LCD splicing screens are the two most commonly used products, so which one is better?
Generally speaking, LED display screens and LCD splicing screens have their own advantages and disadvantages, and their display effects are also different, such as picture integrity, color, brightness, flexibility, etc., and the product performance or price are different, so when we choose, we need to consider many factors, and we can refer to the following points:
1. Clarity
If other factors are not considered, the resolution of LCD splicing screen is higher, such as 46-inch, 49-inch, 55-inch resolution reaches 19201080, and 65-inch and above resolution is as high as 38402160. Through splicing, the resolution can be superimposed, so that the resolution of the whole screen can reach 4K, 6K, 8K or even higher resolution, making the picture display clearer.
The clarity of LED display screen is determined by the size of the dot pitch, mainly including P0.9, P1.25, P1.53, P1.86, P2, P2.5, P3, P4 and other specifications. The smaller the dot pitch, the higher the screen resolution and the clearer the picture display. However, there is still a certain gap between the small-pitch LED series and the LCD splicing screen.
2. Contrast
The contrast of the LCD splicing screen is about 4000~5000:1, and the color richness is good, but it is still a little worse than the LED display. LED displays usually have higher contrast and brighter colors, which makes them more vivid and realistic when displaying images and videos. This richness of color is very important for meetings that need to display high-quality visual content.
3. Brightness
The brightness of LCD splicing screens is usually fixed, generally 500~800cd/m2, which may not be a problem in ordinary indoor environments, but may affect the display effect in environments with strong light. The brightness of LED displays can be adjusted according to the ambient light, which allows them to maintain good display effects under different lighting conditions. This flexibility is especially important for meetings that need to be presented under natural light.
4. Splicing effect
Due to its inherent frame, such as 3.5mm, 2.6mm, 1.7mm, 0.88mm and other specifications, LCD splicing screen will form a visual cut after splicing, which may affect the audience’s viewing experience to a certain extent.
LED display screen can form a seamless whole after splicing, which enables it to provide a smoother and more coherent visual effect when displaying content. This seamless display effect is particularly suitable for multimedia lecture halls that need to display complex charts or large amounts of data.
5. Flexibility of size and shape
The customization ability of LCD splicing screen in size and shape is relatively weak, because its single screen size is large, the screen body is flat, and some arcs or other shapes cannot be made, and it is also more complicated to install and transport.
LED display screens can be customized in different sizes and shapes as needed. The module size is very small, and the soft module can also be bent in a large arc, which can cover the entire wall and provide an immersive viewing experience. This flexibility enables it to adapt to multimedia lecture halls of various sizes and shapes.
In general, LED display screens have obvious advantages in seamless splicing, color performance, brightness adjustment, and flexibility of size and shape, and are particularly suitable for multimedia lecture halls that require high-quality display effects and flexibility.
However, LCD also has its unique advantages in certain specific scenarios, such as when high-definition display effects are required or when the budget is limited. Therefore, the choice of large display screen for multimedia lecture halls should be determined based on the specific multimedia lecture hall display needs and budget.
