Outdoor LED Digital Displays are used in outdoor environments, using light-emitting diodes to emit autonomous light to display information on the screen. At present, it has been widely used in sports venues, advertising media, leasing, stage performances, energy, conference centers, radio and television, transportation, real estate, etc.
What is the driving method of Outdoor LED Digital Display?
How to choose the manufacturer of Outdoor LED Digital Display?
How should the follow-up inspection and maintenance of Outdoor LED Digital Display be carried out?
The driving method of Outdoor LED Digital Display should be comprehensively determined according to the expected display effect and budget. Outdoor LED Digital Display is generally driven by constant current, and the driving methods are divided into static scanning and dynamic scanning. In simple terms, static scanning means that one pin of the driver chip controls an LED, and dynamic scanning means that one pin of the driver chip uses refresh. way to control several LEDs to light up. The static scanning display effect is relatively good, the light loss is small, but the cost is relatively high; the dynamic scanning display effect is relatively poor, the light loss is large, but the cost can be reduced. Common dynamic scans include 1/2 scan, 1/4 scan, 1/8 scan and 1/16 scan.
Examples of judgment methods are as follows:
Module resolution: 16×16
Pixel composition: 1R 1G 1B driver IC: MBI5024 (16 bits)
In the case of driving a mode:
Number of LEDs: 16×16×3=768
Static scan if 48 driver ICs are used
1/2 scan if 24 driver ICs are used
If 12 driver ICs are used, 1/4 scan
The production process, management specifications and technical processes of Outdoor LED Digital Display manufacturers not only seriously affect product quality, but also are closely related to post-maintenance, so the choice of manufacturers is very important.
1. Multi-party consultation, multi-reference solutions, and comparison of selected lamp bead brands, control chips, LED packaging process and other key parameters related to product quality.
2. Check the successful cases of the manufacturer, and evaluate the strength of the manufacturer through the past successful cases.
3. Go to the production workshop for on-site inspection, understand the manufacturer's production process, welding process, assembly process, and choose a manufacturer with guaranteed technology.
The follow-up inspection of Outdoor LED Digital Display includes many areas, such as LED display waterproof, heat dissipation layer, LED display waterproof coating, rain shielding area on the display screen, heat dissipation space on both sides, power supply line, etc. These basic components and products It constitutes the entire Outdoor LED Digital Display with good stability of graphics and text. In the later stage of technical maintenance, unified management and maintenance of these parts is required. When the product is rusted, unstable or damaged, it needs to be replaced in time to ensure that the entire display safe use.
