“…However, the dichroic ratios of the polarizers previously achieved by photoalignment are no more than 20, which is unsatisfactory for practical applications [7,8]. Recently, we have demonstrated high-performance polarizers with a dichroic ratio more than 50 [9,10]. To fabricate the polarizer, 1% AD-1 molecules ( Figure 2) are dissolved in chlorobenzene and form uniform thin films a thickness around 100 nm by spin coating.…”

Smart windows are attractive because of their numerous advantages such as elegance in construction design and energy conservation. Smart windows with variable transmission are especially desirable for obvious reasons. The simplest way to make a variable transmission smart window is to use two patterned polarizers, and control the transmission by changing the relative position of the two polarizers. We have demonstrated a high-dichroic-ratio polarizer by photoalignment and proposed a simple one-step photo-copy method to realize a continuous axis varying polarizer. The patterned polarizer shows high optical performance, and its thickness is as thin as 100 nm, which is favorable in practical window applications.

“…Because of the coating preparation method, it can achieve ultra-wide, ultra-thin polarizer and makes up for the poor thermal and moisture stability of the traditional polarizer. The coatable polarizer is mainly divided into three types such as lyotropic chromonic liquid crystal(LCLC) [2], photoalignment dichroic dye type [3] and guest-host type [4]. However, the coatable polarizer based on LCLC has the problems of full color limitations and low polarization performance.…”

In this paper, we fabricated the coatable polarizer based on guest‐host effect between the host polymerizable liquid crystal and the guest dichroic dye. However, its thermal stability is poor. We had attempts to optimize the structure of its materials and we obtained the optimized polarizer. It had a very small color difference of 2.91, and its DOP was only reduced from 99.0% to 96.2% with a samll loss of 2.7% after being heated at 90°C for 120 hours. It shows that the thermal stability is greatly enhanced. It will benefit the coatable polarizer's development of applications in ultra‐thin, ultra‐wide size and flexible display fields.

“…The most widely used poly vinyl alcohol (PVA)‐based polarizing film has served as an important component for a long time, although other components of the display system have undergone many changes, because of its excellent polarization efficiency of >95% . However, polarizing films are required to keep up with the display industry trends that demand new platforms, owing to their low light‐transmission characteristics that account for the loss of a significant portion of the display light.…”

Development of new types of optical components applicable to flexible and stretched substrates is essential for designing innovative display platforms for wearable and outdoor applications. Here, a novel polarizer based on highly aligned macroscopic carbon nanotube (CNT) sheets with flexibility, thermal stability, high polarization efficiency, and high transmittance is introduced. Since the conductive multiwalled CNTs are essentially held together by van der Waals forces, wire‐grid‐type polarizers of well‐aligned conductive CNTs in one direction can be developed without complex and difficult manufacturing processes. The CNT sheet exhibits uniform polarization efficiency in the visible light region and maintains its polarization characteristics without physical deformation even at temperatures greater than 100 °C. Moreover, the transmission according to the angle formed by two CNT sheets follows the Malus law, similar to a typical polarizer. Finally, the applicability of the CNT sheet polarizer on a commercial liquid crystal displays monitor is demonstrated.
