Smart window
Liquid crystal (LC) is a well-known material which has been extensively researched in the field of light shutter. Our team have demonstrated several novel LC materials with multiple functions and multiple stable states for utilizing to advanced transparent display and smart window applications and also successfully integrated the LC into flexible substrates for versatile development.
Multi-function Smart window film
Our team has successfully broken through the bottleneck and integrate the novel liquid crystal material into flexible substrates. The multi-function smart window “film” can be directly laminated onto existing window glass so that the glass becomes electrically switchable between transparent, tinted, privacy protection, and image display states as user needs. Remote control of the smart window is easily done by connecting it to a smartphone or switch through WiFi, Bluetooth, etc. It overcomes the major challenges of current smart windows, including single function and the high cost of glass replacement. A start-up Brilliant Optronics spun-off from LCP lab is also established for commercial development.

Multi-stable LC Light shutter
Cholesteric liquid crystal are a versatile material which can be switched between several states including planar (P), focal-conic (FC), homeotropic (H) and uniform lying helix (ULH) states. Unlike to conventional bi-stable cholesteric liquid crystal (CLC) which can be stable at P and FC states, the developed bi-stable CLC successfully let the H state become stable. Furthermore, the developed tri-stable CLC can be electrically or optically switchable between ULH, P, and FC. The multi-stability can provide various optical properties and has extensive potential applications.

High-contrast GHLC light shutter
Our dynamic brightness tuning technology enhances imaging and goggles-based applications by adapting to various conditions for optimal performance. We specialize in high-contrast light shutters with selectable coloration, enabling precise light control and customization. These innovative solutions are ideal for applications demanding clarity and adaptability, offering reliable performance in diverse environments.
Transparent display
The image quality of the transparent AM-OLED depends strongly on the background, resulting in poor contrast and image distortion. In this work, a transparent display with high image quality that combines AM-OLED and dye-doped cholesteric liquid crystal is demonstrated.
