Specialized Video Modules for Greeting Cards and Media Boxes: Sizing, Memory, and Applications
来源: | 作者:Haiyan Guangren Trade Co., Ltd. | 发布时间 :106 days ago | 110 次浏览: | Share:
This article focuses on specialized video modules designed for greeting cards and media boxes, detailing their technical specs (2.4-inch to 10.1-inch screens, 128MB to 16GB memory), application adaptations, selection criteria, and future innovations.
In terms of core hardware, screen sizes are tailored to use cases: 2.4-inch for mini greeting cards; 4.3/5-inch for mid-sized cards/desktop media boxes; 7/10.1-inch for premium media boxes/large cards. Memory configurations match functionality: 128MB–512MB SDRAM for basic 2.4-inch modules (5-minutes); 1GB–4GB 4 for 4.3–7-inch modules (20–30 minutes); 8GB–16GB for 10.1-inch modules (1+ hours).
A selection framework links screen size, memory, encoding, use cases, and advantages . Future innovations include GPMI Type-C connectors (144Gbps bandwidth) and Ada Lovelace-derived decoding (30% lower power).
The conclusion emphasizes that these modules balance content richness and form factor, with optimal deployment relying on aligning specs with user needs (personal messages or product showcases).

Video modules tailored for greeting cards and media boxes represent a fusion of compact hardware design and user-centric functionality. These integrated systems—combining displays, memory, and decoding capabilities—must balance form factor constraints with playback performance. This article examines the technical specifications, application-specific adaptations, and selection criteria for modules featuring 2.4-inch to 10.1-inch screens and 128MB to 16GB memory configurations.

1. Core Hardware Specifications by Screen Dimension

1.1 Display Sizing and Performance Metrics

Each screen size addresses distinct use cases, with resolution and power consumption scaled to application needs:

  • 2.4-inch Modules: Optimized for miniaturized video greeting cards, these feature 320×240 QVGA resolution (typical for small-format visuals) and TFT LCD panels with 300:1 contrast ratios. Their compact footprint (≈61×46mm) fits standard folded card dimensions, while low-power LED backlighting enables 8–12 hours of continuous playback on button-cell batteries .

  • 4.3-inch & 5-inch Modules: Bridging portability and clarity, 4.3-inch (480×272) and 5-inch (800×480) modules suit mid-sized greeting cards and desktop media boxes. IPS panels in these sizes deliver 178° viewing angles—critical for shared content like wedding invitations or product demos—and support 24-bit color depth for lifelike imagery .

1.2 Memory Configuration and Playback Capabilities

Memory options (128MB–16GB) dictate content capacity and playback smoothness, aligned with encoding efficiency:

  • 128MB–512MB SDRAM: Powers basic 2.4-inch greeting card modules, supporting H.264-encoded videos up to 5 minutes at 320×240 resolution. This range leverages compact frame buffers to minimize power draw .
