(I) Advertising Promotion
As an efficient advertising medium, elevator screens are suitable for various commercial advertising placements. In office buildings, they can target white - collar workers by promoting advertisements for financial management, high - end electronic products, business training, etc. In residential communities, they can focus on residents' living needs and promote home improvement services, fresh food delivery, educational courses, and other content. In shopping malls, they can highlight promotions of retail brands, catering discounts, entertainment events, and other information. By precisely targeting the audience and fully utilizing the enclosed and high - frequency contact characteristics of the elevator space, the advertising exposure rate and conversion rate are significantly increased, helping advertisers maximize their commercial value.
(II) Information Display
- Basic Information:It can display real - time information such as the elevator's running status (floor, up/down direction), time, and weather, providing convenient references for passengers.
- Public Service Information:In hospitals, it can display the distribution of departments, expert consultation schedules, and medical treatment procedures; in schools, it can push class schedules, campus activities, and announcements; in commercial complexes, it can present store navigation, event arrangements, parking guidance, etc., effectively improving the service efficiency of the place and the user experience.
- Emergency Notifications:In case of emergencies such as fires or power outages, the screen can quickly switch to the emergency notification interface and promptly convey key information such as evacuation routes and emergency measures to ensure the safety of personnel.
(III) Interactive Services
Elevator screens equipped with touchscreens support passengers in performing interactive operations such as floor selection, information query, and service reservation. For example, in office buildings, users can reserve meeting rooms and order meals through the touchscreen; in hotels, they can inquire about nearby scenic spots and book travel services; in shopping malls, they can participate in interactive lucky draws and obtain personalized shopping recommendations, enhancing user engagement and fun.
II. Specification Parameters
(I) Screen Specifications
- Size:Common sizes include 10.1 inches, 15.6 inches, 18.5 inches, 21.5 inches, etc., which can be flexibly selected according to the size of the elevator car space. For small residential elevators, 10.1 - 15.6 - inch screens are suitable to ensure that they do not occupy too much space; for large commercial elevators or office building elevators, 18.5 - 21.5 - inch screens can be selected to ensure clear display of information.
- Aspect Ratio:The common aspect ratio is 16:9, which conforms to human visual habits and is suitable for playing diverse content such as videos and pictures.
- Thickness:With an ultra - thin design, generally controlled at 15 - 30mm, it is easy to install and does not affect the internal aesthetics and space layout of the elevator.
(II) Display Performance
- Resolution:It supports a minimum resolution of 1920×1080 (Full HD), and high - end products can reach 3840×2160 (4K), ensuring delicate and clear images, text, and rich colors.
- Brightness:The brightness ranges from 400 - 800cd/m² and can be automatically adjusted according to the usage environment. For residential elevators with dim indoor lighting, the brightness is maintained at 400 - 500cd/m²; in commercial places with sufficient light, the brightness can be increased to 600 - 800cd/m², ensuring that the screen content is clearly visible under various lighting conditions.
- Contrast Ratio:The static contrast ratio is ≥1000:1, and the dynamic contrast ratio is ≥5000:1, enhancing the layering of the picture, making black purer and white brighter, and improving the visual effect.
- Response Time:≤8ms, effectively avoiding motion blur and afterimage phenomena in dynamic images, ensuring smooth video playback.
(III) Hardware Configuration
- Processor:It adopts high - performance ARM or X86 architecture processors with a main frequency of ≥1.5GHz, ensuring smooth system operation and strong multi - task processing capabilities, and enabling quick responses to commands such as advertisement switching and information updates.
- Memory:It has 2GB or more of RAM and 8GB or more of ROM, supporting the storage of large - capacity advertising materials and system software while ensuring operation speed.
- Interfaces:It is equipped with various interfaces such as HDMI, USB, Ethernet, and WiFi, facilitating content transfer by connecting to external devices (such as USB drives and computers), and supporting wired and wireless network connections for remote control and content updates.
- Touchscreen (Optional):It uses capacitive or infrared touchscreens, supporting 10 - point touch, with precise positioning, sensitive response, long service life, and the number of touch operations can reach more than 1 million times.
(IV) Network Functions
- WiFi:It supports both 2.4GHz and 5GHz frequency bands, conforms to the 802.11ac protocol, has fast transmission rates and stable signals, enabling remote content updates, device monitoring, and management.
- 4G/5G (Optional):It has a built - in 4G/5G module, suitable for places where network cabling is difficult, ensuring real - time online connectivity and meeting the need for instant push of emergency information.
III. Quality Standards
(I) Safety Standards
- Electrical Safety:It complies with GB 4943.1 Information technology equipment - Safety - Part 1: General requirements, and is equipped with perfect grounding protection, overvoltage protection, and short - circuit protection functions to prevent electrical leakage, electric shock, and other safety accidents.
- Mechanical Safety:The casing is made of high - strength, flame - retardant ABS or aluminum alloy materials, and the fire protection grade reaches the UL94 V - 0 standard, with impact resistance and wear resistance. The screen is firmly installed and has passed vibration tests and drop tests to ensure that it will not loosen or fall off during the operation of the elevator.
(II) Reliability Standards
- Operating Temperature: - 10ºC - 50ºC, adapting to the ambient temperature changes in different regions and seasons to ensure stable operation of the equipment.
- Operating Humidity:10% - 90% (non - condensing), without affecting performance and service life in humid environments.
- Mean Time Between Failures (MTBF):≥50000 hours, with high reliability, reducing maintenance frequency and costs.
(III) Environmental Standards
- Environmentally Friendly Materials:It uses environmentally friendly materials free of lead, mercury, and other harmful substances, in line with the requirements of the RoHS Directive, avoiding environmental pollution.
- Energy Consumption Standards:The energy efficiency level reaches Grade 2 or above, with standby power consumption ≤5W, and normal operating power consumption controlled at 15 - 50W depending on the screen size, being energy - saving and environmentally friendly.
