1. Versatile Thin-Film Polarizers for Flexible Applications

Thin-film polarizers on flexible substrates are showcased using in-situ photoalignment or spin-coating techniques. PET films are selected as flexible substrates. The proposed approach holds promise for flexible display applications, offering low cost, durability, and chemical and thermal stability benefits.

2. Precision Micro-Patterned Polarizers Utilizing Photoalignment Technique

The photo-orientation method of azo-dye materials (AD1) enables micro-patterned polarizers by changing the alignment of the azo-dye upon exposure to polarized light with a different polarization direction. This highlights the unique advantages of the photoalignment method in the applications of micro-patterned polarizers.

We developed a solution-based ultra-thin polarizer for liquid crystal displays, The produced polarizer exhibits excellent optical performance with a dichroic ratio of over 150. The film thickness is less than 200nm. The photoalignment method achieves the alignment of dichroic AD1 film. This technology shows excellent prospects for developing high-performance, coatable polarizers with scalability and lower-cost manufacturing potential. Figure 3 shows a TN-LCD with the in-cell polarizers.

4. Wide-Spectrum Thin-Film Polarizer and In-Cell Polarizer for LCDs

Through post-chemical treatment to photo-aligned AD1 thin-film polarizer, the absorbance band is broadened to cover the full spectral band of the display, ranging from 400 nm to 650 nm. The AD1-H polarizer is advantageous in its photo-stability as it is not sensitive to blue or UV irradiation. Broadband in-cell polarizers are fabricated, exhibiting long-term stability and regular drive capability without voltage boost through optimization of the layer structure..

5. In-Cell Polarizer Technology for Color Conversion LCDs

With the technology of the in-cell polarizer, we develop a novel color conversion type liquid crystal display. Color conversion materials are patterned to substitute the color filter layer. By eliminating the absorption loss of conventional color filters, the efficiency of LCD can be enhanced. Using advanced narrow-band color converters, the LCD color gamut can be improved.
