microdisplay Integrated kit 0.39 inch OLED Microdisplay 640x400 resolution 1000cd/m2 for AR VR headsets

DESCRIPTION

This micro oled display Integrated kit is composed with 0.39 inch micro oled display,15X magnifiering optical priam, and CVBS display driver board, all components well assembled and can be directly used into devices;

The 0.39-inch OLED microdisplay integrated kit described here is a compact, high-luminance imaging solution tailored for AR/VR headsets and near-eye display systems. It combines a micro-OLED panel with an HDMI-compatible driver architecture, enabling efficient signal integration while delivering a nominal resolution of 640×400 (system-level output) derived from a high-density 1024×768 pixel array. With peak luminance up to 1000 cd/m², high contrast, and fast response characteristics, the module is engineered to balance optical performance, power efficiency, and mechanical compactness.

Technical Architecture

Microdisplay Core

At the core of the system lies a 0.39-inch silicon-based OLED microdisplay featuring an RGB vertical stripe configuration. The panel integrates 2.38 million subpixels within an active area of approximately 8.75 mm × 4.97 mm, resulting in a pixel density exceeding 3000 PPI. This high pixel density is particularly advantageous for near-eye applications, where minimizing the screen-door effect is critical.

The OLED emissive structure provides intrinsic advantages such as self-emission, eliminating the need for a backlight and enabling superior contrast ratios (>10,000:1). Additionally, the display maintains luminance uniformity above 90%, ensuring consistent image quality across the active area.

Signal and Interface Integration

The integrated kit supports multiple input formats, including 24-bit parallel RGB and 16-bit YCbCr, while the HDMI interface layer simplifies compatibility with common video sources. Internally, signal scaling and timing control enable adaptation from native XGA resolution (1024×768) to application-specific outputs such as 640×400, which is often preferred for power-constrained or latency-sensitive systems.

The 60 Hz refresh rate ensures stable image delivery while maintaining low power consumption and thermal load—an important consideration in head-mounted devices.
