How to buy an indoor full-color LED display? _led indoor display | indoor full color display | indoor led advertising screen

Many customers will ask me how to choose an indoor full-color LED display? Let me give you a unified answer from here today. In the indoor environment, the large-scale full-color electronic display screen is larger than 5m2. There are usually three choices: ordinary rear projection, DLP (digital liquid crystal rear projection) and led display. There are usually three options for large-scale full-color electronic display screens with a volume greater than 5m2 in the indoor environment: ordinary rear projection, DLP (digital liquid crystal rear projection) and led display. So how to choose the right display? Please look at the following analysis: the advantages of rear-projection displays are small pixels and high definition, but the disadvantages are low brightness, small viewing angle, and short lens lamp life (only a few thousand hours). The advantage of plasma splicing is that the pixels are small and the definition is high, but the disadvantage is that there are seams. At present, the smallest seam can reach 1mm. Rear projection and plasma displays are suitable for closer viewing. The advantages of the led display are high brightness and no seams, but the disadvantage is that the pixel particles are coarser and the definition is low. At present, the density of the commercial indoor full-color LED display is up to P4, which is 62500 pixels/m2. The LED display is suitable for indoor places where the viewing distance is relatively long. When choosing led indoor display screen, mainly consider the following aspects. 1. Driving method: The driving method of indoor full-color LED display is constant current driving, using dynamic scanning mode (mainly 1/4, 1/8, etc. scanning methods). In the case of the same die, more circuits are used for 1/4 scanning, and the brightness is also higher. 2. Real pixels and virtual pixels. Like outdoor full-color screens, the number of pixels of indoor full-color screens is also divided into real pixels and virtual pixels. 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, mainly P5, P6, P7.62, P8, P10 and other several. 4. Die core. As with outdoor full-color screens, it is generally recommended that the blue tube and green tube of the indoor full-color display adopt Silan Mingxin tube cores, and the red tube adopts Opto Lei or Guangjia tube cores. High-end products are recommended to use Nihon Asia and American Cree die. 5. Package form. The LED surface forms of indoor full-color LED displays include single lamp, sub-surface mount, three-in-one surface mount, and three-in-one surface mount. The appearance is also different. 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; single-lamp viewing angle is relatively small, brightness is slightly higher, and the price is lower. The sub-surface mount is actually a kind of single lamp. Both single lamp and sub-surface mount are cheaper and are a transitional product. After reading the above analysis, I hope it will help you to choose indoor full-color led display.
