023inch Integrated Microoled Displays Advance Compact Wearable Tech

2026-11-02

A 0.23-inch Micro-OLED microdisplay that integrates panel-driving and logic-driving functions has emerged as a compact option for head-mounted display systems, where component size and power consumption are persistent design constraints. The module pairs 640 by 400 resolution with 800 nits of brightness and is aimed at VR and AR glasses, night-vision equipment and electronic sighting systems. Its small package and embedded image-processing features are intended to reduce the space and complexity of peripheral circuitry in near-eye optical devices.

Core technology: an integrated microdisplay approach

The display is built on single-crystal silicon transistor technology, a manufacturing approach that allows driver circuitry to be formed directly on the silicon backplane. By combining panel-driving and logic-driving functions in a single integrated module, the design reduces the board space required for peripheral circuits, a key consideration for lightweight eyewear and portable optical devices.

The resulting package measures 15.6 by 13.6 by 0.2 millimeters, while the active display area is 8.143 by 6.146 millimeters. The module is specified for operation between minus 10 and 70 degrees Celsius, extending its potential use beyond controlled indoor environments.

Specifications at a glance

The 0.23-inch screen delivers nHD+ resolution of 640 by 400 pixels and a luminance rating of 800 candelas per square meter. It accepts parallel RGB 24-bit and YCbCr 24-bit or 16-bit signals. The main technical specifications are summarized below.

Parameter	Specification
Display type	Micro-OLED
Display size	0.23 inch
Resolution	640 × 400 (nHD+)
Brightness	800 cd/m²
Interface	Parallel RGB 24-bit; YCbCr 24-bit/16-bit
Panel dimensions	15.6 × 13.6 × 0.2 mm
Active display area	8.143 × 6.146 mm
Operating temperature	−10°C to 70°C

The combination of a small active area and a relatively high pixel density is intended for near-eye optical systems, where the display image is magnified by lenses and prisms. The module is positioned for applications requiring high contrast, fast response and a wide color gamut.

Applications and development support

The display is intended for consumer devices including VR and AR headsets, digital camera viewfinders and head-mounted televisions. In professional settings, it is suited to night-vision devices, thermal imagers and electronic sighting systems, where fast response and high contrast can aid image clarity and target recognition.

A companion CVBS/AV driver board measuring 30 by 14 millimeters is designed to bring the panel up quickly for evaluation. Together with a provided magnifying prism, the board forms a prototype development kit for engineers integrating the display into optical systems. Built-in image-processing functions, including vertical and horizontal image inversion and Orbit support, are intended to simplify system integration.

Frequently Asked Questions

Can the Micro-OLED display be connected directly to a computer's video output?

The module is designed primarily for embedded systems and supports parallel RGB and YCbCr interfaces. To connect a standard video source, the supplied CVBS/AV driver board must be used for signal conversion, and the input resolution must match the module's 640 by 400 specification.

Is 800 nits sufficient for outdoor use in bright conditions?

800 nits is a medium-to-high brightness level suited to indoor and semi-outdoor environments. In direct, extreme sunlight, a hood or optical compensation method is recommended to maintain legibility.

Does the driver board support custom input resolutions?

The board is customized for the 0.23-inch screen and supports a maximum resolution of 640 by 400. Input signals above that resolution require scaling upstream; otherwise, the image may fail to display properly or may be distorted.
