In today's digital wave, LED display has been from large shopping malls, stadiums, ‘exclusive’, into the street shops, community activity centres, to become a powerful assistant to convey information and create an atmosphere.

Pre-planning and installation: stable foundation

Site survey is the first step, different scenes on the LED display requirements vary. If the outdoor advertising space, to consider the wind, rain erosion, direct sunlight and other factors, to ensure that the installation structure is solid and waterproof and sunscreen; like a large screen on the roof of a busy commercial street, it must be based on the building load-bearing professional engineers, local meteorological data to design the steel structure frame, wind resistance level of the same time to reserve access to maintenance channels. Indoor venues such as conference rooms, exhibition halls, focusing on the viewing distance and viewing angle to determine the appropriate screen size and pixel spacing, small training room to choose P2.5 - P3 spacing of the small size screen, to ensure that the close-up picture fine, the audience to see the details of the chart.

Installation, strictly in accordance with the instructions and installation drawings. Wall-mounted installation for indoor walls, first find the load-bearing wall, with expansion bolts to fix the pendant, and then splicing screen, adjust the flatness error control in millimetres, to avoid the picture ‘wave’ distortion; column outdoor installation, deep excavation of the foundation, pouring a concrete foundation, erecting columns, installation of the screen after calibration of the verticality of the process of laying cables, power cables, signal cables, slots, and other cables. , power line, signal line sub-slot or add shielding, anti-signal interference, electrical hazards.

Equipment connection and commissioning: activate the potential

Connecting equipment like ‘building bridges’, so that the display and the signal source ‘dialogue’. HDMI cable, DVI cable to connect the computer graphics card and display receiver card, transmission of high-definition video images; multi-screen splicing or long-distance transmission scenarios, with the help of fibre-optic transceiver, the optical fiber ‘relay’, stable signal delivery, to solve the problem of signal attenuation. For occasions that require external audio, the audio cable from the computer audio port to the screen supporting audio, ‘sound’ for the screen.

Initial debugging fine, turn on the power, first check the module, whether the lamp beads are normally lit, there are no bad spots, dark areas, there are problems in a timely manner to mark the replacement. Into the control software (such as Nova Nebula, Ling Xingyu, etc.), according to the screen pixel, the size of the precise set of parameters, correct the colour, brightness, contrast, outdoor screen according to the ambient light sensor feedback, set the intelligent dimming, daytime bright display, the night brightness reduction energy saving and light pollution; splicing demand for the large screen, fine-tuning the splicing seam colour, brightness consistency, the picture across the screen transition naturally and seamlessly.

Daily operation and content management: always changing and always new

Convenient daily operation is the most important, control software interface familiar with the operation, can easily import graphic and video materials. For daily promotions, merchants can import designed posters and short promotional videos into the software, set the playback duration, sequence and special effects (fade-in/fade-out, shutter switching, etc.), and then push them to the screen for real-time updating with a single click; and for announcements and notifications in the community, the text information is inputted into the software, and simple fonts and suitable colours are selected to convey the content in a clear and eye-catching way.

The content is updated strategically, at regular intervals according to the audience's work and rest schedule and scene requirements. The shopping mall screen focuses on new product promotions and event previews during the day, and plays relaxing music videos at night to attract nighttime consumers; the campus information screen broadcasts club activities and lost and found during class time, and displays course schedules and campus slogans during class time to match the rhythm of teachers and students on campus, and cleans up outdated and redundant materials on a regular basis to ‘lighten the load’ of storage and optimise playback performance. 

Maintenance: prolonging life

Cleaning and maintenance is the maintenance of the ‘mandatory course’, regular power outages with a soft, lint-free cloth, special cleaning agents to wipe the screen surface dust, stains, outdoor screen must also clean up the heat sink hole debris, anti-clogging caused by overheating faults; check the electrical wiring with or without breakage, aging, interface loosening in a timely manner to tighten; key components such as power supply, receiving card with redundant parts, failure can be quickly replaced. Key components such as power supply and receiver card are equipped with redundant parts, so that they can be quickly replaced in case of failure, and the display can be guaranteed to be ‘running continuously’. Regular professional testing of brightness, colour indicators, calibration parameters, to ensure that the picture quality as in the beginning, so that the LED display screen in the careful care, lasting shine in the scene, and efficiently deliver value information.
