At present, more and more LED display screens are entering indoors, especially large hotels and large supermarkets, which are more favored by advertisers. So what are the requirements for large hotels to choose indoor full-color LED displays?
In the indoor environment, full-color display screens with an area of u200bu200bmore than 5 square meters mainly have three choices: ordinary rear projection, DLP (digital liquid crystal rear projection) and LED display.
The advantages of rear-projection display screens are small pixels and high definition, but the disadvantages are low brightness, small viewing angle, and short lens lamp life (only a few thousand hours). The advantage of plasma splicing is that the pixels are small and the definition is high, but the disadvantage is that there are seams. The smallest seam can reach 1mm.
Rear projection and plasma display screens are suitable for closer viewing.
The advantage of LED display is high brightness and no seams. The disadvantage is that the pixel particles are coarser and the definition is low. At present, the density z of the commercial indoor full-color LED display is P4, which is 62500 pixels/square meter. The LED display is suitable for indoor places where the viewing distance is relatively long.
When choosing a hotel full-color LED display, the following aspects should be considered.
1. Real pixels and virtual pixels. Like outdoor full-color LED displays, the number of pixels of indoor full-color screens is also divided into real pixels and virtual pixels.
2. Die core. A good die can guarantee the quality of the LED.
3. Package form. The LED surface forms of indoor LED display screens include single lamp, sub-surface mount, three-in-one surface mount, and three-in-one surface mount, with different appearances. The advantages of surface mount packaging are large viewing angle, good luminous consistency, and easy automatic welding. It is the mainstream product of full-color LED screens, but the price is relatively high; single-lamp viewing angle is relatively small, brightness is slightly higher, and the price is lower. Sub-surface mount is actually a kind of single lamp. Both single lamp and sub-surface mount are cheaper and are a transitional product.
4. Density. Because indoor full-color LED chips generate a lot of heat and control circuit density is high, the dot density of commercial full-color screens cannot be made very high.
5. Drive mode. The driving method of indoor full-color LED display is constant current driving, and adopts dynamic scanning method (mainly 1/4, 1/8, etc. scanning methods). In the case of the same die, more circuits are used for 1/4 scanning, and the brightness is also higher.
