Detailed explanation of outdoor vertical advertising machine resolution
The resolution of outdoor vertical advertising machines is a key parameter that determines its display effect, which directly affects the clarity, fineness and information carrying capacity of the picture. At present, mainstream models mainly support 1920×1080 (Full HD) resolution, and can be customized and upgraded to 3840×2160 (4K UHD) ultra-high resolution, and have 4K×2K@60fps ultra-clear video decoding capabilities to meet the visual display needs in different scenarios.
Basic resolution configuration
The standard configuration of 1920×1080 full HD resolution (1080p) is the most common display specification for outdoor vertical advertising machines. This resolution can provide good clarity on a 32-55 inch screen, with a moderate pixel density (PPI), suitable for medium-distance viewing (2-5 meters). The 1080p resolution has lower hardware requirements, more stable system operation, and relatively economical content production costs. It is suitable for playing regular picture carousels, basic video advertisements, and other application scenarios that do not require extremely high definition. In direct sunlight, a 1080p screen with a high-brightness panel (above 700cd/m²) can still maintain good visibility.
4K UHD Upgrade Option
High-end models can be customized with a 3840×2160 (4K UHD) resolution, which has four times the number of pixels of 1080p. This ultra-high-definition resolution has obvious advantages on large-size screens of 55 inches and above, and can present extremely delicate picture details. It is particularly suitable for displaying product close-ups, high-definition image materials, or interactive content that needs to be viewed at close range. 4K resolution greatly improves the sharpness of text display, and when playing information bulletins, data charts and other content containing small text, it can ensure that it can still be clearly identified from a distance. It is worth noting that the true 4K display effect requires a source of corresponding resolution to be perfectly presented, which puts higher requirements on content production.
Video decoding capability
Modern outdoor vertical advertising machines generally support 4K×2K@60fps ultra-clear video decoding, which means that the device can smoothly play 3840×2160 resolution, 60 frames/second high frame rate video content. High frame rate decoding ensures the smoothness of dynamic images, and there will be no stuttering or smearing when playing fast-moving scenes (such as sports highlights, car advertisements, etc.). This performance relies on powerful video processing chips (such as Rockchip RK3588 or Amlogic S905X4), and needs to be equipped with sufficient running memory (usually more than 4GB) and an efficient cooling system to maintain stable operation.
Resolution selection suggestions
For conventional outdoor applications (such as bus stops, shopping mall corridors, etc.), 1920×1080 resolution can meet basic needs and is more cost-effective. In places such as high-end commercial spaces and brand experience stores that pursue extreme visual effects, 4K resolution can significantly enhance brand image and advertising value. Special applications such as digital art displays and virtual fitting mirrors must use 4K resolution to achieve ideal results. It is worth noting that the increase in resolution will increase system load and energy consumption accordingly. Large-size 4K advertising machines usually require stronger cooling design and higher-specification power supply support.
Technology development trend
With the maturity of 8K technology, outdoor advertising machines will develop towards higher resolutions in the future. At present, some manufacturers have launched experimental products with a resolution of 7680×4320 for special display scenarios. At the same time, the combination of display technologies such as HDR high dynamic range and wide color gamut is bringing the image quality of advertising machines to a new level. In terms of decoding capabilities, a new generation of processors that support 8K/30fps or 4K/120fps have begun to be commercialized, which will further expand the application possibilities of outdoor digital signage.
