Generally, in an indoor environment, the LED display area of the banquet hall will be relatively large. Therefore, in this case, there are three options: ordinary rear projection, DLP (digital liquid crystal rear projection) and LED display.

The advantages of ordinary rear-projection displays are small pixels and high definition, but the disadvantages are low brightness, small viewing angle, and short life of the lens lamp (only a few thousand hours). The advantage of DLP is that the pixels are small and the resolution is high. The disadvantage is that there are seams. At present, the minimum 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, but the disadvantages are that the pixel particles are thicker and the definition is lower. At present, the more economical models of indoor full-color LED screens are P2.5, P3, and other models are P2, P1.66, etc. The led display is suitable for indoor places with a long viewing distance.

Generally, in an indoor environment, the LED display area of the banquet hall will be relatively large. Therefore, in this case, there are three options: ordinary rear projection, DLP (digital liquid crystal rear projection) and LED display.

When choosing a banquet hall LED display, you can consider the following aspects:

1. Tube core. As with the outdoor full-color LED screen, it is generally recommended that the LED of the indoor full-color display use light-emitting diodes, and high-end products are recommended to use Japan's Nichia and the United States' die.

2. Package form. The advantages of surface mount package are large viewing angle, good luminous consistency, easy automatic welding and processing, and it is the mainstream product of full color screen.

3. Density. Because the indoor full-color LED chip generates a large amount of heat and the control circuit density is high, the point density of the commercial full-color screen cannot be made very high.

4. Drive mode. The driving methods of indoor full-color LED screens are constant current driving, using dynamic scanning methods (mainly 1/4, 1/81/16 and other scanning methods).

5. Refresh frequency. Improve the refresh rate, no flicker or trailing in camera shooting.

Other considerations, including the scale and brand of LED display manufacturers, price, use, installation location environment, etc., the above are some suggestions from LCF on the selection of LED display screens for hotel banquet halls.
