How to choose the indoor LED display? These considerations must be considered

Currently, more and more led display entered the room, especially the big hotels and large supermarket more get the favour of advertisers. So large hotel choose what are the requirements of the indoor full color? In indoor environment, the area of more than 5 ㎡ large full-color electronic display mainly ordinary display, DLP Digital liquid crystal display) And LED display three choices. Display type display pixel is small, the advantages of high resolution, defect is low brightness, small Angle, lens lamp life short ( Only a few thousand hours) 。 Plasma splicing and pixel is small, the advantages of high resolution, the disadvantage is that there are flat-fell seam, the smallest flat-fell seam can be up to 1 mm. Display and plasma display panel is suitable for a closer look. Led display has the advantage of high brightness, no flat-fell seam, the disadvantage is that pixels coarser particles, low resolution. The density of the commercialization of indoor full color led display z do P4, which is 62500 pixels/m 2. Led display for viewing distance far indoor Spaces. Powerful giant color you choose attention when choosing indoor LED display screen, LED display is mainly from the following several aspects to consider. (1) solid pixels and virtual pixels. Like outdoor full color, indoor full color pixels are divided into two pixels and virtual pixels. (2) pipe core. Good can guarantee the quality of the LED tube core (3) packaging format. Indoor LED display LED surface form a single light three spell a table, the table is stuck, post and so on several and triad table, appearance is not the same. Table stick encapsulation is Angle is large, the advantages of light-emitting uniformity is good, easy to automatic welding process, is the mainstream of full-color LED product, but now the price is relatively high; Single light Angle is relatively smaller, slightly high brightness, low prices. The table stick is also one of the single lamp. Single lamp and the table are relatively cheap, is a kind of transitional product. (4) density. Due to large indoor full color LED chip calorific value, control circuit density is higher, so now the commercialization of full color dot density also can't be very high. 5. Drive way. Indoor full color LED display drive mode are constant current drive, a dynamic scanning way ( Mainly has 1/4, 1/8, scanning mode etc. ) 。 In the same tube core, 1/4 scan circuit more, brightness is high.
