Product Introduction

Product Description

The 0.39-inch OLED microdisplay integrated kit is a compact, high-performance visualization module designed primarily for electronic viewfinders (EVF).

The integrated microdisplay kit described here is centered on a 0.39 inch OLED microdisplay designed for compact visual systems such as electronic viewfinders (EVF) and near-eye AR/VR devices. The module delivers a high-density resolution of 1024×768 within an active area of 7.92 × 6.00 mm, achieving a pixel density of 3255 PPI. With a typical luminance of 500 cd/m², contrast ratio exceeding 10000:1, and support for multiple digital video formats, the kit combines precise imaging capability with a CVBS-integrated driving solution, offering a practical pathway for rapid system deployment.

General Specification

Microdisplay Architecture and Optical Performance

The microdisplay adopts OLED-on-silicon technology, enabling high pixel density within a minimal footprint. The RGB vertical stripe arrangement ensures accurate color reproduction, while the fine dot pitch of 7.5 μm supports detailed image rendering essential for near-eye visualization.

Image Quality and Luminance Characteristics

With a luminance level of 500 cd/m², the display maintains adequate brightness for enclosed optical systems such as EVF modules and AR optics. The contrast ratio greater than 10000:1 contributes to deep black levels and high dynamic range, which is particularly beneficial in immersive applications.

The progressive scanning method at a refresh rate of 60 Hz ensures stable image presentation with minimal motion artifacts, supporting a comfortable viewing experience in dynamic scenes.

Electrical Integration and Signal Compatibility

The module is designed with flexible signal compatibility, allowing it to interface with various video sources through both digital and analog pathways.

Video Input and Processing

The display supports:

· 24-bit parallel RGB input

· 24-bit YCbCr digital input

· 16-bit YCbCr (4:2:2 format)

In addition, the integrated CVBS board simplifies system design by enabling direct connection to composite video sources, which is advantageous in legacy systems or rapid prototyping environments.

Signal Enhancement and Control

An internal signal processing unit provides:

· Contrast adjustment functionality

· 8-bit input scaling with 10-bit grayscale output via D/A conversion

· Horizontal and vertical image mirroring

A 2-wire serial interface is implemented for configuration and control, allowing efficient communication with host processors.

Mechanical Design and Integration Flexibility

The compact structural design reflects the requirements of wearable and embedded optical systems. The display panel measures 11.72 × 8.41 mm, while the full module with flexible printed circuit (FPCA) extends to 50.4 × 15.6 × 2.0 mm.

Environmental Reliability

Engineered for demanding conditions, the module operates reliably across a temperature range of -40℃ to +65℃, with storage tolerance extending from -55℃ to +80℃. This robustness supports applications in both consumer electronics and specialized industrial or outdoor devices.

Functional Features for AR/VR Integration

Digital Video Processing Capabilities

The module incorporates a digital visual interface supporting multiple input formats, allowing seamless integration with contemporary processing platforms. The inclusion of grayscale enhancement and contrast tuning ensures adaptability to varying optical system requirements.

Orientation and Image Adjustment

Built-in horizontal and vertical mirroring functions simplify optical path design, especially in AR/VR systems where image inversion is often required due to lens configurations.
