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 display screens 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 advantages of DLP are small pixels and high definition, but the disadvantage is that there are joints. At present, the smallest joint can reach 1mm. Rear projection and plasma displays are suitable for viewing at a closer distance. As for the indoor LED display, the advantage is high brightness and no seams, but the disadvantage is that the pixel particles are thicker and the definition is lower. At present, the commercialized indoor full-color LED screen is more economical model P5P6, and other models include P3P4P72P8 and so on.
The led mirror screen is suitable for indoor places with a long viewing distance. When choosing LED displays for banquet halls, the following aspects can be considered: 1. Tube core. Like outdoor full-color LED screens, it is generally recommended to use light-emitting diodes for indoor full-color LED screens, and for high-end products, it is recommended to use Japanese Nichia and American dies.
2 Package form. The advantages of surface mount packaging are large viewing angle, good luminous consistency, and easy automatic welding and processing. It is the mainstream product of full-color screens. 3 density.
Due to the high heat generation of 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 drive mode. The drive mode of indoor full-color LED screen is constant current drive, adopting dynamic scanning mode (mainly 1/4, 1/81/16 and other scanning modes).
5 Refresh frequency. Improve the refresh rate, no flickering and tailing under the camera shooting. Other considerations include the scale and brand of the LED display manufacturer, price, purpose, installation location and environment, etc. The above are some suggestions for the selection of LED screens in hotel banquet halls.
