ADB-100: Unified Interface for 7″ and 10.1″ TFT Displays
New ADB-100 adapter board standardizes LVDS interfaces for 7″ and 10.1″ TFT displays from different manufacturers – first series models with 1024×600 and 1280×800 resolution now available.
ADB-100 startet mit 7″- und 10.1″-LVDS-Displays: Die Schnittstelle für 1024×600 und 1280×800 jetzt verfügbar
The ADB-100 is a compact, single-sided adapter board that makes 7″ and 10.1″ LCD TFT displays with LVDS interface controllable via a standardized board-to-wire interface. It generates all necessary LCD bias voltages (VGL, VGH, VCOM) from a single 3.3 V supply, integrates a powerful LED driver with up to 480 mA and 40 V output voltage as well as a standardized I²C touch controller interface. The circuit board is mounted directly on the back of the display, significantly reducing the integration effort. The first series products are now available: a 7″ display with 1024 × 600 pixels and a 10.1″ model with 1280 × 800 pixels.
Technical features of the ADB-100 at a glance:
- LCD bias generation: Triple regulated outputs (positive/negative/VCOM) with adjustable switch-on sequence (tₕ₁, tₕ₂) – factory-adjusted to the respective panel.
- LED backlight driver: Up to 480 mA, up to 40 V, dimming ratio 10,000:1 at 100 Hz PWM; operation with either +5 V or +12 V input voltage.
- Standardized connectors for:
- LVDS data and display supply
- Backlight power supply and control (PWM/EN)
- I²C touch controller (SDA, SCL, INT, Reset)
- LVDS loop-through: Color depth and data mapping identical to the target panel.
- Mechanics: Single-sided mounting, low profile, direct display rear mounting.
The ADB-100 is designed for industrial use and supports operating temperatures according to the display specification. The factory configuration of bias voltages and sequence timings ensures immediate plug-and-play operation without additional software or hardware adjustments. Further display sizes and resolutions are in preparation.
