Micro-LED displays face fundamental challenges in light management and fabrication precision. Current implementations show optical crosstalk between adjacent pixels, with light leakage reducing contrast ratios and color accuracy. Manufacturing processes must position and connect micro-LEDs with submicron precision while maintaining yields above 99.99% for commercial viability in high-resolution displays.
The core engineering challenge involves balancing optical performance, manufacturing complexity, and transparency in displays that must deliver both high brightness and clear see-through capabilities.
This page brings together solutions from recent research—including sidewall reflective coatings that prevent inter-pixel light leakage, hybrid inorganic-organic pixel architectures, integrated functional elements between pixels, and novel transfer techniques for precise micro-LED placement. These and other approaches address the practical demands of mass-producing transparent micro-LED displays while maintaining optimal visual performance.
1. Transparent Display Panel with Subpixels Comprising Micro LEDs and Surrounding Transparent Regions
BOE TECHNOLOGY GROUP CO., LTD., 2022
A transparent display panel with subpixels containing micro LEDs and transparent regions to enable both display content and external scene viewing. The transparent regions surround the opaque micro LEDs to allow light transmission. The display uses micro LEDs driven by integrated circuits for high brightness and efficiency. The transparent regions are made of materials like glass or organic insulating layers with openings matching the subpixel layout. This allows external light to pass through while blocking light emitted by the micro LEDs. The transparent display can be used in applications like augmented reality, vehicle displays, and transparent signage where viewers can see both the display and the surrounding environment.
2. Double-Sided Micro LED Display Panel with Opposed Thin Film Transistor Substrate Configuration
Century Micro Display Technology (Shenzhen) Co., Ltd., 2020
Micro LED display panel with double-sided display capability. The panel has a thin film transistor (TFT) substrate with spaced apart micro LEDs on it. Unlike conventional micro LED displays that only show images from one side, this panel allows display on both sides. This is achieved by having the TFT circuitry on one side and the micro LEDs on the opposite side, enabling separate images to be displayed on each side. The panel can have electrical connections to the TFT and micro LEDs from both sides or through the substrate.
3. Transparent Display Panel with Dual-Sided Emission Featuring Substrate-Integrated Micro LED Shields
PLAYNITRIDE INC., 2020
Transparent display panel with dual-sided display capability that reduces thickness compared to using two separate displays. The panel has a transmissive substrate with top-emitting and bottom-emitting micro LEDs. The bottom LEDs have shields on their top surface to prevent light from being transmitted back into the substrate. A shielding layer between the top LEDs and substrate prevents light transmission in that direction as well. This allows separate images to be displayed on both sides of the panel without requiring two separate displays and reducing thickness compared to stacking displays.
