At present, more and more LED screens are coming into the interior, especially large hotels and supermarkets are more favored by advertisers.What are the requirements for large hotels to choose indoor full color screens?

In the indoor environment, the large full-color electronic display with an area of more than 5m2 mainly has three choices: ordinary display, DLP(digital LCD display) and LED display.

The advantages of the display are small pixels, high definition, low brightness, small viewing Angle, and short lens lamp life (just a few thousand hours).The advantages of plasma splicing are small pixel points and high definition, while the disadvantages are stitching. At present, the minimum stitching can reach 1mm.The back-projection type and plasma display screen are suitable for closer viewing.The advantages of LED display are high brightness, no stitching, and the disadvantages are coarse pixel particles and low clarity.Currently, the commercial indoor full-color LED display has the highest density of P4, namely 62,500 pixels/meter 2.The LED display is suitable for viewing the remote indoor places.

The problem that should consider when choosing LED indoor display screen

When choosing LED indoor display screen, the following aspects are mainly considered.

Virtual pixels and virtual pixels.Like the outdoor full color screen, the pixels of the interior full color screen are divided into real pixels and virtual pixels.

(2) pipe core.As with the outdoor full color screen, it is generally recommended that the indoor full color blue tube and green tube adopt the tube core of the shiming core and the red tube adopt the tube core of light lei or guanggu.High - end products are recommended to use Japanese Japan and CREE.

Type of encapsulation.The indoor full-color LED display screen has several LED surface forms, such as single lamp, sub-watch sticker, three parts and one table sticker, and three parts and one table sticker. The appearance is also different.The advantages of table sticker packaging are large perspective, good luminescence consistency, and easy to be automatically welded. It is a mainstream product of full-color LED screen, but the price is relatively high now.Single - lamp perspective is relatively small, brightness slightly high, low price.Subwatch stick is also a kind of single lamp actually.Single lamp and sub - TAB are relatively cheap, is a transitional product.

(4) density.As the indoor full-color LED chip has a higher calorific value and higher density of control circuit, the point density of commercial full-color screen cannot be very high at present, mainly including P5, P6, P7.62, P8 and P10.

Drive mode.The indoor full-color LED display is driven by constant current and adopts dynamic scanning mode (mainly 1/4, 1/8, etc.).With the same core, a quarter of the circuits used for scanning are more and brighter.
