Updated:
Transparent micro-LED displays are becoming pivotal in industries like augmented reality and smart glass technology. These displays offer the unique ability to project vivid images while remaining see-through, a feature increasingly demanded in modern applications. However, achieving this transparency without compromising display quality presents significant challenges, especially in balancing light efficiency and display clarity.
Engineers and researchers face hurdles such as managing optical crosstalk, enhancing light extraction, and integrating complex circuitry without obstructing visibility. The delicate task of maintaining color accuracy and brightness while ensuring structural integrity is also a formidable challenge. These issues become more pronounced as display designs strive for thinner and more flexible forms.
This page explores a range of technical solutions, such as reflective sidewall coatings and hybrid pixel structures, designed to address these challenges. You'll find insights on improving light extraction, reducing optical interference, and integrating advanced circuitry for enhanced transparency. These strategies collectively aim to improve display performance, ensuring reliable and efficient operation in diverse applications.
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.
