HDMI to MIPI DSI Display Adapter Suit for Double Screen

HDMI to MIPI DSI Display Adapter for Dual Screen Applications

This adapter converts HDMI input to dual-channel 4-lane MIPI DSI output for dual-screen display projects. It is built around the Toshiba TC358870XGB video bridge IC and an STM32F103 control MCU.

The stated maximum display configuration is up to 3840×2160 at 30Hz. Actual output behavior depends on the HDMI source, operating system, display timing, MIPI panel compatibility, and software configuration.

Primary integration use cases include embedded display development, industrial control interfaces, Raspberry Pi display projects, retail display terminals, and OEM/ODM display system prototyping.

HDMI Input

HDMI Type A input interface supporting HDMI 2.0/1.4 source connection according to the original product specification.

Video Bridge and MCU Control

Toshiba TC358870XGB handles video bridge conversion. STM32F103 supports control functions including screen switching and backlight-related control.

Dual MIPI DSI Output

Dual-channel 4-lane MIPI output through a 60-pin MIPI DSI connector for compatible MIPI display modules.

Extended Desktop Mode

Designed for dual-screen applications where the host system needs separate display areas. Final behavior depends on graphics driver, operating system, and display configuration.

Mirror Display Mode

Suitable for duplicated visual output in kiosks, promotional terminals, device status screens, and compact operator interfaces.

Backlight and Screen Control

Supports screen switching and backlight-related control functions for embedded display projects requiring controlled display output behavior.

Referenced Compatible Displays

3.4-inch round TFT display, 800×800 resolution, 350nits brightness, MIPI interface.

2.89-inch Sharp high-resolution VR display, 1440×1440 resolution, MIPI interface.

Third-Party Display Verification

Third-party MIPI panels should be checked against connector pinout, lane mapping, panel initialization sequence, resolution, timing, voltage rails, and backlight requirements.

For unsupported panels, contact technical support with the panel datasheet before ordering for integration confirmation.

Power Input

Use a stable 4.5–5.5V Micro USB power source. Reserve current margin above the stated 500mA typical value when backlight load or connected display conditions vary.

MCU Control

STM32F103 control functions are used for screen switching and backlight-related operation. Confirm firmware requirements for customized display panels.

Resolution Planning

The stated maximum is 3840×2160 at 30Hz. Confirm panel timing, source output capability, and dual-display behavior before final enclosure design.

Thermal Use

For wide-temperature applications, confirm real operating temperature, enclosure airflow, display backlight load, and stability under the target use condition.

Industrial Control Systems

Applicable to dual-screen monitoring, machine interface panels, process display terminals, and embedded control prototypes requiring HDMI source input and MIPI display output.

Portable Medical Device Display Evaluation

Can be evaluated for diagnostic equipment display subsystems. Final medical compliance, electrical safety, EMC, reliability validation, and product-level certification remain the responsibility of the device manufacturer.

Retail Digital Signage

Suitable for mirrored content display, compact promotional kiosks, information terminals, and small-format signage systems using HDMI input sources.

Interface Customization

LVDS, eDP, HDMI, USB-C, DVI, and VGA output-related customization can be discussed for industrial and commercial display projects.

Function Expansion

Signal conversion, voltage regulation, backlight control, touch integration, and panel-specific configuration support are available depending on project scope.

Enclosure Options

IP-rated waterproof and dustproof housing options, shock-resistant design requirements, custom colors, logos, and housing materials can be specified for OEM programs.

Bulk Order Programs

Volume pricing, sample availability, lead time, inspection standards, and long-term supply requirements should be confirmed with the engineering and sales team before production planning.

Official Datasheet

Use the official PDF to verify mechanical drawings, absolute maximum ratings, recommended operating conditions, interface timing, power rail requirements, register settings, and reliability limits.

Raspberry Pi Setup Scripts

Configuration code is available for Raspberry Pi setup. Confirm display model, operating system version, and panel configuration before using the scripts in a production project.

Installation Video Guide

Use the installation video as a visual reference for adapter setup. Electrical validation should still be completed against the datasheet and target display specification.
