MiniLED Local Dimming Platform

FPGA-based image analysis and backlight control for high-zone-count MiniLED displays—from interface adaptation and pixel-to-zone processing to driver integration, panel tuning and motion-clarity optimization.

Platform variants scale from hundreds to more than 10,000 local-dimming zones, with video interfaces and backlight links configured around the target display system.

A Configurable Local Dimming Platform

The platform is for MiniLED programs that put video timing, image analysis, backlight control and panel behavior on one schedule.

Panel timing, luminance statistics, zone mapping, driver communication and power limits share that path. Hardware and FPGA settings follow the interface, resolution, zone topology, driver IC and optical stack.

Platform Architecture

A modular processing path allows the video interface, FPGA resources, zone topology and backlight communication to be configured around the target display.

MiniLED Local Dimming Platform reference architecture — Reference architecture. Interfaces, timing resources and backlight links are configured around the target display system.

Interface and Platform Variants

Configurable platform variants support eDP, V-by-One, LVDS and MIPI-DSI video paths. Interface configuration and validation are completed according to the target panel and system architecture.

Interface Typical Role Engineering Scope

eDP Embedded display input Link configuration, timing adaptation and panel integration

V-by-One High-bandwidth display path Lane configuration, timing alignment and TCON coordination

LVDS Industrial and established panel platforms Mapping, timing adaptation and compatibility validation

MIPI-DSI Compact embedded display systems Lane configuration, command/video mode integration and panel bring-up

Available combinations depend on the selected FPGA, panel timing, bandwidth, connector definition and system architecture.

Local Dimming Processing

The FPGA processing path converts incoming image content into synchronized zone-level backlight control. Luminance analysis, zone mapping, spatial and temporal filtering, and power-aware output control are tuned together for the target panel and optical system.

Luminance Analysis
Frame and regional statistics for backlight demand estimation.
Pixel-to-Zone Mapping
Conversion of image content to the physical MiniLED zone topology.
Spatial & Temporal Control
Halo management, transition response and frame-to-frame stability.
Power-Aware Control
Backlight output coordinated with current, thermal and panel constraints.
