At present, more and more led display into the indoor, especially large hotels and supermarkets more advertisers' favor. So what are the requirements for large hotels to choose indoor full color screens?

In the indoor environment, the area of more than 5 square meters of large full-color electronic display mainly has the ordinary rear projection, DLP(digital LCD rear projection) and LED display 3 choices.  

The advantages of rear-projection display are small pixels and high resolution, but the disadvantages are low brightness, small Angle of view and short life of lens lamp (only a few thousand hours). The advantage of plasma splicing is small pixel points, high clarity, the disadvantage is that there is a joint, the minimum joint can reach 1mm.  

Rear-projection and plasma screens are good for closer viewing.  

led display has the advantage of high brightness and no joint, but the disadvantage is coarse pixel particles and low clarity. At present, the density z of commercial indoor full-color led display screen is P4, namely 62500 pixels/m 2. led display is suitable for viewing distance of indoor places.

 

When choosing LED indoor display screen, mainly consider from the following aspects.  

① Real pixel and virtual pixel. Like outdoor full-color screens, indoor full-color screens have two types of pixels: real pixels and virtual pixels.  

② Tube core. Good tube core can ensure the quality of LED  

③ encapsulation form. Indoor LED display LED surface forms have a single lamp, sub-table paste, three combination one table paste and three in one table paste, the appearance is not the same. Table sticker packaging has the advantages of large Angle of view, good luminous consistency, easy automatic welding processing, is the mainstream of full color LED screen products, but now the price is relatively high; Single light Angle is relatively small, slightly brighter, lower price. Subtable paste is actually a single lamp. Single lamp and sub - surface patch are cheaper, is a transitional product.  

 ④Density. Due to the indoor full color LED chip heat, control circuit density is higher, so now the commercial full color screen point density can not be done very high.  

⑤ Driving mode. Indoor full color LED display is driven by constant current, using dynamic scanning mode (mainly 1/4, 1/8 scanning mode). With the same core, the 1/4 scan uses more circuits and is brighter.
