At present, more and more LED display screens have entered the room, especially in large hotels, large supermarkets, exhibition centers, etc., which are more favored by advertisers. So what are the requirements for using indoor full-color LED displays in these indoor places? Next, LCF sent a editor to take everyone to take a look!


In the indoor environment, large-scale full-color electronic displays with an area greater than 5 square meters mainly have three options: ordinary rear projection, DLP (digital liquid crystal rear projection) and LED display.


The advantages of rear projection display 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 advantage of plasma splicing is that the pixels are small and the definition is high. The disadvantage is that there is a seam. At present, the smallest seam can reach 1mm.


Rear-projection and plasma displays are suitable for closer viewing.

The advantage of the LED display is high brightness and no seams, but the disadvantage is that the pixel particles are thicker and the definition is lower. At present, the density of the commercialized indoor full-color LED display can reach P4, that is, 62500 pixels/m2. The led display is suitable for indoor places where the viewing distance is long.


LCF sends a small editor to teach you how to choose the indoor full-color LED display. When choosing an indoor LED display, the main considerations are from the following aspects.


①Real pixels and virtual pixels. Like outdoor full-color screens, the number of pixels of indoor full-color screens is also divided into two types: real pixels and virtual pixels.


② die. A good tube core can guarantee the quality of the LED.


③ Package form. The LED surface forms of indoor LED display screens include single lamp, sub-surface sticker, three-in-one surface sticker, and three-in-one surface sticker, etc., and the appearance is also different. 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 indoor full-color LED screens, but the price is relatively high now; the viewing angle of a single lamp is relatively small, the brightness is slightly higher, and the price is lower. . The sub-surface sticker is actually a kind of single lamp. Single lamps and sub-surface stickers are relatively cheap and are a transitional product.


④ 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.


⑤Drive mode. The driving mode of indoor full-color LED display is constant current driving, and adopts dynamic scanning mode (mainly 1/4, 1/8 and other scanning modes). In the case of the same die, more circuits are used for 1/4 scanning, and the brightness is also higher.


The special part of the indoor full-color LED electronic display is that other core components of the LED display, such as power supply, control system, wire, structure, etc., can be replaced, except for the LED lamp beads, circuit boards, and driver chips. together are irreplaceable. Therefore, refer to these data in time when purchasing indoor full-color LED electronic displays.
