With the efforts of major manufacturers and enterprises to make small-pitch LED display screens, it has become possible for LED display screens to enter the room. In the past, the projectors and rear projection screens that were often used by major business hotels were slowly replaced by small-pitch LED displays. Hotel LED display is a new thing. Many people still don't know what kind of requirements this indoor LED display needs to meet. What issues should be considered? Here, the editor teaches you how to "Amoy" a good hotel LED display.
1. Comparison of several display designs
The indoor LED display has the characteristics of long life, high brightness, no splicing, etc., which greatly meets the needs of large-scale hotel business meetings and business performances. Compared with a projector, the indoor LED display has higher brightness and better clarity, and it can be almost any size; compared with the rear projection display, the LED display can have no brightness in addition to brightness. Seam.
Second, the issues that should be considered when purchasing hotel led display
1. Die. As with the outdoor full-color screen, it is generally recommended that the blue and green tubes of the indoor full-color screen use the Silan core core, and the red tube use the Guanglei or Guangjia core. For high-end products, it is recommended to use the die of Japan Nichia and American Cree.
2. Packaging form. There are several kinds of LED surface forms for indoor full-color LED display, such as single lamp, sub-surface sticker, three-in-one surface sticker and three-in-one surface sticker. The advantages of surface mount packages are large viewing angles, good luminous consistency, and easy automatic soldering processing. It is the mainstream product of full-color LED screens, but the price is relatively high now; the single lamp viewing angle is relatively small, the brightness is slightly higher, and the price is lower. Subsurface stickers are actually a type of single lamp. Single lamps and sub-surface stickers are relatively cheap and are a transitional product.
3. Density. Because it is a stage performance and conference in an indoor environment, the distance is not very far, and it is sufficient to select an LED display with a density of 5 mm or less than P5.
4. Drive mode. The driving method of indoor full-color LED display is constant current driving, using dynamic scanning method (mainly 1/4, 1/8 and other scanning methods). In the case of the same die, there are more circuits for 1/4 scan, and the brightness is higher.
