023inch Integrated Microoled Displays Advance Compact Wearable Tech

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.

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.

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.

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.
