How to choose hotel LED display?
At present more and more LED display into the indoor, especially large hotels and large supermarkets more favored by advertisers. So what are the requirements for large hotels to choose indoor led display?
In the indoor environment, the area greater than 5 square meters of full-color display screen is mainly ordinary rear projection, DLP (digital liquid crystal rear projection) and LED display 3 kinds of choices.
Rear projection type display has the advantage of small pixel points, high clarity, the disadvantage of lower brightness, small viewing angle, lens lamp life is short (only a few thousand hours). The advantages of plasma splicing is also small pixels, high definition, the disadvantage is that there is a splicing seam, the current minimum splicing seam can reach 1mm.
Rear projection class and plasma display is suitable for closer viewing.
LED display has the advantage of high brightness, no splicing seam, the disadvantage is that the pixel particles are coarse, low clarity. Currently commercial indoor full-color LED display density can do P4, that is, 62500 pixels / m2. LED display is suitable for indoor places with a long viewing distance.
When choosing hotel full color LED display, mainly from the following aspects to consider.
1, real pixels and virtual pixels. Like outdoor full color LED display, the number of pixels of indoor full color screen is also divided into real pixels and virtual pixels.
2, Tube core. Good tube core can ensure the quality of LED.
3, package form. Indoor LED display LED surface form has a single light, sub-surface sticker, three spell a surface sticker and three-in-one surface sticker and so on, the appearance is also different. The advantages of the table sticker package is a large viewing angle, light consistency is good, easy to automatic welding processing, is the mainstream of full-color LED screen, but now the price is relatively high; single lamp viewing angle is relatively small, brightness is slightly higher, the price is lower. Sub-surface sticker is actually a kind of single lamp. Single light and sub-surface sticker are cheaper, is a transitional product.
4, density. Due to indoor full color LED chip heat, control circuit density is higher, so now commercialized full color screen point density can not be done very high.
5, drive mode. Indoor full color LED display drive mode are constant current drive, using dynamic scanning mode (mainly 1/4, 1/8 and other scanning methods). In the case of the same core, 1/4 scanning with more circuitry, brightness is also higher.
