47‐2: Invited Paper: Highly Transparent AMOLED for Augmented Reality Applications

A new transparent display system with human-computer interaction (HCI) will become the key technology of next generation display. We have developed an interactive transparent display system with 17" transparent AMOLED. The transmittance of the transparent AMOLED can achieve 70.6% and the brightness is higher than 483 cd/m 2 . Furthermore, the interactive transparent AMOLED system has successfully verified in intelligent aquarium and ecological box with realtime interactive operation.

et al. 2019

“…The traditional transparent display is re-designed from traditional LCD, OLED display, or projection type display, etc. [1][2][3][4] It is hard to escape from limitations of the technology, so the transparency or other performance is not good enough. In recent years, to meet the market requirement for transparent display, some new transparent displays emerged out, such as Micro/Mini LED display, scattering type PSLC display, etc.…”

et al. 2021

In recent years, the transparent waveguide liquid crystal display (WLCD) technology attracted a lot of attention for the high transmittance. To further improve the display performance, the contrast ratio was systematically optimized in this work. A coarse‐grained model based on Mie scattering was established to perform the limiting theoretical analysis of the contrast ratio of polymer‐stabilized liquid crystal devices. To improve the contrast ratio, we tried different material formulations and optimized the UV polymerization process, and also applied light shielding layer to suppress metal lines reflection. Finally, the contrast ratio can reach to 18:1. With these improvements and the advantage on transmittance, it is believed that the WLCD technology will be applied in various intelligent IoT systems in the near future.

“…With its display and transparent controllability, transparent LCD technology has received more and more attention in recent years. [1][2][3] The ideal transparent display panel can not only see the displayed image, but also the real object behind it. To make sure the panel have optical properties close to transparent glass in the non-display area, PNLC (Polymer Network Liquid Crystal) combined with field-sequential display technology based on time mixing is a perfect method, it is a full-color display module without color filters, paddles and polarizers, so as to achieve a panel transmittance greater than 80%.…”

P‐52: Realization of Transparent LCD with Field Sequence

et al. 2021

A 2.6‐inch Transparent LCD prototype has been developed by using network polymer liquid crystal PNLC (Polymer Network Liquid Crystal) combined with field‐sequential color display technology. Moreover, the display principle of transparent LCD with field sequence was expounded and a contrast ratio enhancement algorithm has been developed to improve the image CR in this paper. As there is an intrinsic problem for the transparent LCD with field sequence that uniformity of brightness is not excellent enough caused by the panel polymer and the side‐in backlight, a novel light‐guiding structure has been developed to provide the uniform surface light source, the picture shows better effect than the traditional processing method which achieved high efficiency light emission (83%) and uniformity (64%). The simulation and experimental results verify the effectiveness of the contrast ratio enhancement algorithm and the novel light‐guiding structure.
