HDMI Micro Driver Board – Type-C Powered OLED/AMOLED Display Evaluation & Demo Board

DMRXHRB HDMI Micro Driver Board – Type-C Powered Display Evaluation & Demo Board

The DMRXHRB is a compact HDMI micro driver board designed for fast display light-up, lab evaluation, customer demonstrations, and early-stage prototyping. It combines Micro-HDMI video input, USB Type-C 5V power input, an FPC screen connector, an onboard control button, and a red rocker power switch on one board.

It is built for engineers who need to verify whether a compatible display module can be powered, connected, and shown with HDMI content before investing time in a custom controller board or full system design.

Micro-HDMI Video Input

Accepts HDMI signal from a PC, single-board computer, or video source through a Micro-HDMI cable.

FPC Screen Connector

Connects the display module through the board-side FPC interface. Correct FPC orientation is required for reliable contact.

USB Type-C Power

Requires a stable 5V supply with at least 1A current capacity before switching the board on.

Control Button & Rocker Switch

The onboard button and red rocker switch support simple manual control during lab testing and demos.

Wiring Procedure

1. Connect the display FPC to the screen interface on the PCB.

2. Confirm the FPC copper side is aligned correctly before locking or seating the connector.

3. Connect USB Type-C power. The power supply must provide 5V and at least 1A.

4. Connect the Micro-HDMI cable from the PC, SBC, or HDMI video source.

5. Turn on the red rocker switch. When HDMI output is active and the panel is compatible, the display shows the projected image normally.

Handling Requirements

Display Evaluation & QC

Light up compatible panels for incoming inspection, optical verification, uniformity checks, and basic visual performance review.

R&D Prototyping

Validate a display concept with HDMI input before designing a custom carrier board or final product controller.

Customer Demonstrations

Prepare a portable HDMI demo setup for sales samples, project reviews, and early customer approval.

Field Debugging

Use the board as a reference HDMI driver during signal checking, power verification, and interface troubleshooting.

Power

Confirm USB Type-C 5V input with at least 1A supply capacity.

Video Source

Use a Micro-HDMI cable from a PC, SBC, or HDMI video output source.

Display FPC

Check FPC orientation and connector alignment before powering on.

Panel Match

Request the compatible panel list before using the board with a new display module.

Custom Driver Design

Support for HDMI, MIPI, RGB, LVDS conversion boards and adapter designs based on a target display module.

Prototype Acceleration

PCBA sampling support for proof-of-concept display projects before mass-production planning.

Bring-Up Guidance

Engineering assistance for HDMI timing checks, power sequence review, FPC handling, and custom evaluation fixtures.
