Airport check-in LED screen
The airport check-in LED screen adopts the XYG-LCD module, featuring high stability, high recognition, wide viewing angle, high contrast ratio, fast response, ease of large-scale combination and maintenance, and has passed multiple functional tests to ensure reliability.
Product Advantages and Features
Compared with ordinary LED displays: Ordinary LEDs tend to have bright spots when displayed for a long time, and the lamp tubes need to be replaced entirely when they fail; XYG-LCD uses LCD as the light switch and uses multiple LED lamp tubes as the backlights. The failure of individual lamp tubes does not affect the overall recognition, and the average time between failures (MTBF) is increased by 3 times. For example, a 24×24 pixel LED display requires 576 groups of RGB LED drivers, while XYG-LCD only needs 128 groups, with a ratio of 4.5:1, significantly reducing the failure rate.
Compared with traditional LCD: Traditional LCD uses white backlight and color filters, resulting in low contrast and a small viewing angle range; XYG-LCD adopts a colorless filtering method, using RGB lamp tubes to control color display, and the display opening rate is not dependent on color, achieving high contrast and wide viewing angle.
Chip-in-built backlight technology: Integrating the three colors (Red, Green, and Blue) onto a single chip, increasing the number of chips and reducing the spacing, enhancing brightness and alleviating the phenomenon of bright spots.
Improvement of pigmentation: RGB emits light through color mixing within the chip, eliminating the pigmentation issues caused by color mixing of separate chips in the traditional method.
Core performance advantages
High recognition: Through the field sequential scanning color display technology, multi-color display is achieved with the same opening rate for each color, thereby enhancing recognizability.
Wide viewing angle: Develop FTN type liquid crystal based on wide-angle film to reduce color differences when viewed from different angles.
High contrast: By combining FTN type liquid crystal with high-efficiency LED backlighting, high contrast display is achieved.
Quick Response: Utilize appropriate liquid crystal panel materials to support rapid response and scrolling display.
Large display applicability: Through unique liquid crystal manufacturing technology, color differences between modules are reduced, and it supports the combined use of multiple rows and multiple segments of devices.
Easy to maintain: The backlight structure is specially designed, making it convenient for replacement and repair. It also has a remote dimming function, allowing the color and brightness to be adjusted according to external signals.
Functional testing and debugging
Seismic resistance performance: The seismic specification during debugging is 1.2G, and the seismic resistance level is 7. This ensures that the equipment can operate stably in a vibrating environment.
Self-diagnosis function: The self-diagnosis function for components such as memory, backlight, and fan, which can monitor the status of the device in real time.
Fault substitution display: When the diagnostic module malfunctions, it automatically switches to the substitution display function to ensure that the information is not interrupted.
Intelligent temperature control: Adjust the intelligent temperature control function to prevent the equipment from overheating and affecting its performance.
Other tests: include functions such as preventing CPU from freezing, preventing lightning strikes, preventing static electricity, preventing sudden power outages, eliminating noise from the AC power supply, and the maintainability test for modular replacement.
Usage Notes
The input voltage for the power supply is 220V. Ensure that the power supply is stable.
The environmental brightness should not exceed 20,000 lux. Avoid direct exposure to strong light as it may affect the display effect.
The visible distance is 35 meters. The installation height and angle should be adjusted according to the actual situation.
The humidity range is 20% to 90% RH (not condensation). Measures to prevent moisture should be taken in humid environments.
The atmospheric conditions require that the surface of the enclosure be treated with anti-pollution, anti-corrosion and anti-salt fog coatings, which can withstand direct sunlight and the display surface should have anti-glare function.
