Generally in the indoor environment, the LED display area of the banquet hall will exceed 3 square meters. Therefore, in this case, there are three options for 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 lens lamp life (only a few thousand hours). The advantages of DLP are small pixels and high definition. The disadvantage is that there are seams. At present, the smallest seams 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. The current commercial indoor full-color LED screen is more economical model is P5P6, other models include P3P4P8 and so on. The led display is suitable for indoor places where the viewing distance is far away.
When choosing the LED display screen in the banquet hall, the following aspects can be considered:
1 die. As with outdoor full-color LED screens, it is generally recommended to use light-emitting diodes for indoor full-color display LEDs, and high-end products are recommended to use Japanese Nichia and American dies.
2 package form. The advantages of surface mount packaging are large viewing angles, good luminous consistency, and easy automatic welding processing. It is the mainstream product of full-color screens.
3 density. Since indoor full-color LED chips generate a large amount of heat and the control circuit density is relatively high, the dot density of current commercial full-color screens cannot be made very high.
4 drive mode. The driving method of the indoor full-color LED screen is constant current driving, using a dynamic scanning method (mainly 1/4, 1/81/16, etc. scanning methods).
5 Refresh frequency. Increase the refresh rate, no flicker or tailing under camera shooting.
Other considerations, including the size and brand of LED display manufacturers, price, usage, installation location environment, etc. The above are some suggestions for the selection of LED screens in hotel banquet halls.
