Products Description
To ensure stable performance, the LUM series outdoor LED digital sign incorporates dual-port mode for easy handling of different right-angle projects. Additionally, it is equipped with aluminum alloy heat sinks to effectively dissipate heat in a timely manner. This innovative design helps to maintain the screen's reliability while delivering optimal performance.

Standby power port
This module comes with two power ports - one serves as the primary port while the other acts as the backup port. This design ensures that the product has a longer lifespan compared to others on the market.

Multiple structured modules
The backplane design of the aluminum alloy is highly efficient in dissipating heat, while its insulation adhesive ensures top-quality sealing. This makes it an ideal choice for applications where heat dissipation matters. Its advanced sealing capabilities also mean it can withstand challenging environmental conditions, providing maximum protection for the equipment it encases.

Convenient maintenance mode
The design is such that both front and rear maintenance are supported, and the central control box can be disassembled.

More secure connections
The installation process is quick and streamlined, with a direct connection to the interface. To produce a similar content by reorganizing the original text information, it is guaranteed that the newly generated content will be markedly different from ChapGPT's response.

LED display repair
LED display is a complex electronic device that may malfunction if used for a long time or improperly operated during use. Here are some common LED display failures and their repair methods:
1. The display does not light up: check whether the power supply is normal, check whether the connection between the display and the power supply is loose, and check whether the power supply and cable are damaged.
2. The display content is not clear: It may be caused by pixel failure, and the damaged pixel needs to be replaced.
3. Display flickering or jitter: It may be caused by unstable power supply voltage or poor cable connection, and it is necessary to check and solve the problem.
4. Color abnormality on the display: It may be due to a problem with the color calibration of the display and the color calibration needs to be redone.
5. Burnt display display: It may be caused by long-term use or high power supply voltage, and damaged parts need to be replaced.
When repairing LED displays, you need to have certain professional knowledge and skills, it is recommended to seek professional technical support and maintenance services. If you need to repair by yourself, it is recommended to understand the structure and maintenance method of the LED display in advance, and use professional maintenance tools and equipment to avoid secondary damage or personal safety accidents.In short, when repairing the LED display, it is necessary to carefully check and judge the cause of the failure, and take appropriate maintenance methods to deal with it to restore the normal working state of the display
LED display moiré phenomenon
The moiré phenomenon of LED displays refers to the visual effect of stripes or grids that appear on the display, which may interfere with the clarity and readability of the displayed content.This phenomenon is caused by the difference in distance and brightness between the pixels of the LED display. As the viewer's perspective moves, different pixels will produce differences in brightness in different locations, creating a fringed or grid-like effect. This phenomenon is usually more pronounced at low gray levels, where the difference in brightness of pixels is more pronounced.In order to reduce the moiré phenomenon of LED display, the following measures can be taken:
1. Optimize the pixel layout and brightness control technology of the display to minimize the distance and brightness difference between pixels.
2. Increase the number of pixels to improve pixel density and resolution, thereby reducing the appearance of streaks and grids.
3. Avoid using low gray levels in the display as much as possible to reduce brightness differences and streak effects.
4. Use visual optimization techniques such as adjusting parameters such as brightness, contrast, and color balance to reduce the effects of moiré phenomenon.
In short, the moiré phenomenon is a common LED display problem, but its impact can be reduced by optimizing the display technology and taking a series of measures.
