The advantages of ordinary rear-projection display screens are small pixels and high definition, but the disadvantages are low brightness, small viewing angle, and short lifespan of the lens lamp (only a few thousand hours). The advantage of DLP is that the pixels are relatively small and the definition is high. The disadvantage is that there are seams. At present, the smallest seam can reach 1mm. Rear-projection and plasma displays are suitable for closer viewing. For indoor LED displays, the advantages are high brightness and no seams. The disadvantage is that the pixel particles are coarser and the definition is low.

　　 More and more hotels will give priority to LED display, not only because of the clear effect, better visual experience. And with the development of the LED industry, the price of indoor LED displays is cheaper and acceptable than before. At present, the more economical model of LED screens in banquet halls is P5 P6, and other models include P3, P4, P7.62, P8, etc. And the larger the model, the more suitable for long-distance viewing, and the area will generally be larger. The following are the common sizes listed

　　 Product model (pixel) density (dot/㎡) module size (mm)

　　 LCF-P3 indoor unit board 111111 points/㎡192*192 LCF-P3 indoor unit board 111111 points/㎡192*192　　　　LCF-P5 indoor unit board 40,000 points/㎡320*160

　　LCF-P4 indoor unit board 62500 points/㎡256*256 LCF-P4 indoor unit board 62500 points/㎡256*128 LCF-P6 indoor unit board 27777 points/㎡192*384

　　 When choosing the LED display in the banquet hall, the following aspects can be considered.

　　 1. Manufacturer. Needless to say, regular LED display manufacturers look at historical years, industry case accumulation, etc., and general products and after-sales are more secure.

　　 2. Model and viewing distance. Generally, if the viewing distance is 6 meters away, it is recommended to consider P5, if it is required to be 8 meters away, it is recommended to consider using P8.

　　3 die. As with outdoor full-color LED screens, it is generally recommended that the LEDs of indoor full-color display screens use light-emitting diodes packaged by Meiyadi, and high-end products are recommended to use Japanese Nichia and American CREE dies.

　　4 package form. The surface mount package 3528 2121 1010 has the advantages of large viewing angle, good luminous consistency, and easy automatic welding process. It is the mainstream product of full color screen.

　　 5 density. Because indoor full-color LED chips generate a lot of heat and the control circuit density is high, the dot density of commercial full-color screens cannot be made very high. Lianchengfa indoor full-color LED screen models include P1.6, P2, and P2.5. P3 P4 P5, P6, P7.62, P8, etc.

　　6 drive mode. The indoor full-color LED display is driven by constant current, and it uses dynamic scanning (mainly 1/4, 1/8, 1/16, etc.).

　　7 refresh rate. Increase the refresh rate, without flickering and tailing under camera shooting.

The above are suggestions on the size and selection of LED display screens in banquet halls, other considerations, price budget, usage, installation location and environment of LED display screens in banquet halls, etc. For more information about the latest products and prices, please contact the LED display manufacturers online Sincerely.
