At present, more and more full-color LED screens come into the room, especially large hotels are favored by advertisers. So what are the requirements for the choice of indoor full-color LED display? Let's take a look
Generally, if the area is larger than 5m2, indoor LED display will be used. Its advantages are high brightness and no stitching. The disadvantage is that the pixel particles are thicker and the resolution is lower. At present, the highest mainstream density of full-color LED displays in commercial rooms is P3, with a dot pitch of 3mm. At present, Lianchengfa Group can achieve 1.8mm.
When choosing indoor full-color LED display, mainly consider from the following aspects.
â‘ Real pixels and virtual pixels. Like outdoor full-color; LED display, the number of pixels of indoor full-color screen is also divided into real pixels and virtual pixels.
â‘¡ Die. As with the outdoor full-color display, it is generally recommended to use the Silan core for the blue and green tubes for the indoor full-color screen, and the Guanglei or Guangjia for the red tube. For high-end products, it is recommended to use Japanese Nichia and American CREE die.
â‘¢ 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 packaging are large viewing angle, good luminous consistency, and easy automatic welding process. It is the mainstream product of full-color LED screens, but the price is relatively high now; the viewing angle of single lamp 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.
â‘£ Density. Because indoor full-color LED chips generate more heat and the control circuit density is higher, the dot density of commercial full-color screens cannot be made very high now, mainly including P4, P5, P6, P7.62, P8, P10 Several.
⑤ 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.
The above are the matters needing attention regarding the selection of LED display screens in hotels. Other factors affecting the purchase: LED display price, which is related to the area of ​​the screen, and is also related to the display model, etc .; the manufacturer's reputation and brand strength are also important reference factors.
