With the continuous development of my country's urbanization process, urban landscape lighting design has received widespread attention. It combines local history, culture, natural landscape and other composition elements and designs to show people a higher standard of spiritual culture and is also the image of the city. symbol of. In recent years, all parts of the country have been actively promoting the construction of smart cities, and local governments have paid more and more attention to urban planning and construction and landscape lighting projects. The transparent LED display screen has the characteristics of transparency, lightness and thinness.

Common driving methods include static scanning and dynamic scanning. Static scanning is divided into static real pixel and static virtual. Dynamic scanning is also divided into dynamic real image and dynamic virtual.

1. Transparent LED display scanning method classification:

Scanning method: In a certain display area, the ratio of the number of lines lit at the same time to the number of lines in the entire area.

1. Dynamic scanning: Dynamic scanning implements "point-to-column" control from the output of the driver IC to the pixels. Dynamic scanning requires a control circuit, and the cost is lower than static scanning, but the display will be worse and the brightness loss will be greater. .

2. Static scanning: Static scanning implements "point-to-point" control from the output of the driver IC to the pixels. Static scanning does not require a control circuit, and the cost is higher than dynamic scanning, but the display effect is good, the stability is good, and the brightness is lost. Smaller advantages.

2. Distinguishing by environment:

Indoor single and double colors are generally scanned at 1/16.

Indoor full color is generally 1/8 scan,

Outdoor single and double colors are generally scanned at 1/4.

Outdoor full color is generally a static scan.

3. Transparent LED display 1/8 and 1/16 scanning modes:

1/8 scan: Under other conditions being the same, the 1/8 scan display is only half as bright as the 1/4 scan display, and is suitable for semi-outdoor and indoor use. The control method is to increase from 1/4 of four LEDs to 8 LEDs. The current is swept between 8 LEDs.

1/16 scan: This is a lower brightness driving method and is generally only used indoors. The same is true for how they are controlled.

4. Distinguishing by model:

1. Scanning method of indoor LED transparent screen: constant current 1/16, constant current 1/8, constant current 1/6

2. The scanning method of outdoor transparent LED display: constant current 1/2, static.
