How to select the display screen for meeting display
How to select LCD splicing screen, LED display screen, projector and conference display screen. We need to know from the viewing distance, price, display effect and so on.
LCD splicing screen: LCD splicing screen is suitable for close viewing, with high definition, wide viewing angle and high resolution; Projectors are usually viewed at close range, but at a long distance: for example, in the projection of a large conference room, the audience behind may not be able to see clearly. If LEDs are used indoors, small spacing LEDs are required. If large spacing LEDs such as P10 are used, there will be long-distance blur and need to display high definition and high resolution, so it is necessary to select small spacing LEDs for indoor use.
Secondly, LED screen, the resolution of LED is determined by the distance between points. Generally, the LEDs used for indoor display are concentrated below P3. Although the resolution can not reach HD display, it is better than projector.
In the case of small and medium-sized meeting rooms, the price of the projector is low (the price is transparent, the connection and use are simple, but the service life of some parts is not high, and the comprehensive use cost is not low); The second is LCD splicing screen. If 55 inch 3.5mm splicing is selected, each flat can reach less than 10000;. Then there is the LED display screen (if you choose products with small spacing, such as products below p2.0, the price will be 10000-30000 / square meter).
The definition of indoor LED display screen is determined by the resolution of the screen, which is also directly related to the display technology. In this regard, liquid crystal technology has natural advantages. For example, if the resolution of one screen like LCD splicing screen reaches 1920 * 1080, four pieces of splicing can realize 4K display, so LCD splicing screen has high definition and good texture.
Difference is defined as projection. I believe that most users who have contacted know that the image presented by the projector will have a sense of snowflakes and the picture will be white.
Brightness determines the contrast between the screen and natural light and light. The higher the brightness of the screen, it will not reflect light compared with light. At this point, the brightness of LED screen is very high, which is one of the main reasons why most outdoor large screens use LED. Therefore, when used in indoor environment, the brightness of LED screen is also high, but when displayed in indoor environment, high brightness is not necessarily an advantage, because the indoor light is usually not so strong. If the screen brightness is too high, it will cause glare and is not suitable for close viewing.
Relatively speaking, the brightness of LCD splicing screen is more moderate, lower than LED screen and higher than projection screen. Moreover, the brightness of industrial LCD splicing screen is higher than that of TV. The purpose is to solve the problem of reflection, which is more suitable for indoor use.
However, the brightness of the projector is very low, so we usually need to close the curtains and turn off the lights when using it, otherwise we can't see the content on the screen because of reflection.
The effect of displaying the same image on projector, LCD splicing screen and LED screen is completely different. In addition to clarity and brightness, the direct difference is the difference between color saturation and contrast.
In terms of color display, LCD splicing screen has rich colors, followed by LED and projection, so the effect of LCD display is very good whether playing video or pictures.
Later product upgrade and expansion: the projector can only transmit signals on one computer, while LCD splicing screen and LED are more expensive, but it supports synchronous input of multiple computer signal sources, and can switch the display at will, making it more intelligent and networked.
In general, if you do not consider the complex display requirements in the later stage, you can consider the projector, which is easier to install. If you want to have a good display effect, you should consider LCD splicing screen (high-definition image quality, meeting various complex display requirements such as low gray level and low brightness). If viewing from a distance in a large conference room, it is recommended to use LED display.
