Precautions for selecting LED display screen in hotel banquet hall

Generally, in the indoor environment, the area of LED display screen in the banquet hall will exceed 3 m2. 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 display screen are small pixels and high definition. The disadvantages are low brightness, small viewing angle and short service life of lens lamp (only a few thousand hours). DLP has the advantages of small pixels and high definition. The disadvantage is that there are seams. At present, the minimum seam can reach 1mm. Rear projection and plasma display screens are suitable for close viewing. For indoor LED display, the advantages are high brightness and no seam, while the disadvantages are coarse pixel particles and low definition. At present, the economic model of commercialized indoor full-color LED screen is p5p6, and other models include p3p4p8. LED display screen is suitable for indoor places with long viewing distance.

When selecting LED display in banquet hall, the following aspects can be considered:

1 core. Like the outdoor full-color LED screen, it is generally recommended that the LED of the indoor full-color display screen be led, and the tube cores of Japan, Japan, Asia and the United States are recommended for high-end products.



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



3 density. Due to the large heating capacity of indoor full-color LED chip and high density of control circuit, the point density of commercial full-color screen can not be very high.



4. Driving mode. The driving mode of indoor full-color LED screen is constant current driving and adopts dynamic scanning mode (mainly 1 / 4, 1 / 81 / 16 and other scanning modes).



5 refresh rate. Improve the refresh rate, and there is no flicker and trailing under the camera shooting.



Other considerations include the scale and brand, price, purpose, installation location and environment of LED display manufacturers. The above are some suggestions on the selection of LED screens in hotel banquet halls.
