How to choose the LED display.outdoor electronic advertising led display screen manufacturer

　　In the indoor environment, large full -color electronic displays with an area of more than 5m2 mainly include three options: ordinary back investment, DLP (digital liquid crystal back investment) and LED display.

　　The advantage of the back doting display is that the pixels are small, the sharpness is high, and the disadvantage is that the brightness is low, the viewing angle is small, and the life of the lens light is short (only a thousand hours). The advantages of plasma stitching are also small pixels, high sharpness, and disadvantages are that there are seams. At present, the smallest seam can reach 1mm.

　　Back doting and plasma display are suitable for viewing closer.

　　The advantages of the LED display are high degree of brightness, no seams, and the disadvantage is that the pixels are thicker and the sharpness is low. At present, the density Z of the commercial indoor full -color LED display is P4, that is, 62500 pixels/m 2. The LED display is suitable for watching the indoor places far away.

　　When selecting the LED indoor display screen, the issues that should be considered should be

　　When using the LED indoor display, it is mainly considered from the following aspects.

　　① Pixel and virtual pixels. Like outdoor full -color screens, the pixels of the indoor full color screen are also divided into real pixels and virtual pixels.

　　② Tube core. Good pipe cores can ensure the quality of LED

　　③ encapsulation form. The LED surface form of the Jinhe Optoelectronics indoor LED display includes single lights, sub -table stickers, three -in -one table stickers, and three -in -one table stickers. The appearance is also different. The advantages of table stickers are large perspectives, good luminous consistency, easy to automatically weld and processed. It is the mainstream product of full -color LED screen, but now the price is relatively high; the perspective of the single light is relatively small, the brightness is slightly higher, and the price is low. The sub -table sticker is actually a single light. Single lamps and Asian table stickers are cheaper, and they are a transitional product.

　　④ Density. Because the indoor full -color LED chip has a large heat and a high control circuit density, the point density of the full color screen of the commodity is not yet high.

　　⑤ Driving method. The driver of the indoor full -color LED display is constant -current driver, using dynamic scanning methods (mainly scanning methods such as 1/4, 1/8). In the same case, the circuit for 1/4 scan is more and the brightness is higher.
