Technology | Precautions for choosing hotel banquet room LED display

625 views admin 2020-03-31

Generally in an 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 display are small pixels, 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 patchwork. At present, the smallest patchwork 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 disadvantages are coarse pixel particles and low definition. The currently commercialized indoor full-color LED screen is the more economical model P5P6, and other models are P3P4P72P8 and so on. The led mirror screen is suitable for indoor places with a long viewing distance.


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

  • 1. Die. As with outdoor full-color LED screens, it is generally recommended to use LEDs for indoor full-color displays, and high-end products are recommended to use Japan's Nichia and the United States.
  • 2. Package form. The advantages of surface mount package are large viewing angle, good light consistency, easy automatic welding and processing, and it is the mainstream product of full color screen.
  • 3. Density. Due to the large amount of heat generated by indoor full-color LED chips and the high density of control circuits, the dot density of commercial full-color screens cannot be made very high.
  • 4. Driving method. The driving methods of indoor full-color LED screens are constant current driving, and dynamic scanning methods are used (mainly 1/4, 1/81/16 and other scanning methods).
  • 5. Refresh frequency. Increase the refresh rate without flickering or smearing when shooting with the camera.

Other considerations include the size and brand of the LED display manufacturer, price, use, installation location environment, etc. The above are some suggestions on the selection of LED display screens in hotel banquet halls.
