描述
HD-B6L is a full‑color LED display control card developed for LED poster screens, mirror screens and splicing walls. It integrates video processing and sending‑card functions on one board and adds cloud‑based remote cluster management, so network deployment and content updates can be handled from anywhere.
Key Features
- Strong loading capacity: a single card drives up to 1.3 million pixels, supports a maximum width of 16384 pixels or height of 8192 pixels; cascaded cards reach up to 2.6 million pixels.
- Multi‑window playback: up to 2 × 4K, 6 × 1080P, 10 × 720P or 20 × 360P video windows on one screen.
- Sync, async and mixed modes: plays stored programs offline, mirrors a live HDMI signal, or mixes both — with auto‑scaling and picture‑in‑picture.
- HDMI splicing: 1 × HDMI 1.4b input and 1 × HDMI 1.4b output for cascade splicing of up to 10 levels, building one seamless screen from several displays.
- Wireless control: built‑in 2.4 GHz Wi‑Fi (AP and STA modes) with mobile‑app control.
- Remote cluster management: optional 4G module (nano SIM) connects the card to the cloud platform for remote monitoring and publishing; onboard relay allows remote power switching (AC 250V~3A / DC 30V~3A max).
- Environment sensing: two dedicated sensor ports support temperature, humidity, brightness, wind speed, wind direction, noise, PM2.5, PM10 and CO₂ sensors, plus a GPS port for positioning and time sync.
- Generous on‑board storage: Android 11 system, 2 GB RAM + 16 GB storage, plus USB 3.0 for program updates and capacity expansion.
- Rich media support: JPEG/BMP/GIF/PNG/WEBP images and MPEG‑1/2, MPEG‑4, H.264, H.265/HEVC, VP8, VP9, H.263, VC‑1, MJPEG video.
