چکیده

We report on the fabrication of a carbon nanotube field emission backlight unit (CNT-BLU) and its application for liquid crystal displays (LCD). The CNT-BLU was operated with locally controllable luminance and impulse-type scanning. The local luminance control, which is based on a very small block size of 1 cm(2), consisted of local dimming and local brightening. This resulted in the contrast ratio of the LCD-TV to be as high as 300 000:1. A fast response time of ∼5.7 ms was also achieved from the LCD-TV lit by CNT-BLU, originating from the impulse-type scanning. In addition, the CNT-BLU showed long-term emission stability and high luminance uniformity.

Prospects of quantum dots-based liquid crystal displays

We report a systematic photometric study of LCD based on quantum dot (QD) backlight, and find the optimal emission spectrum combination in terms of system efficiency and wide color gamut. A QD-based LCD has potential to achieve 120% AdobeRGB color gamut in CIE 1931 and 140% in CIE 1976 color space, while keeping the same energy efficiency as conventional backlights. Moreover, we present a trans...

A fast-response A-film-enhanced fringe field switching liquid crystal display

We propose a new A-film-enhanced fringe field switching (A-FFS) liquid crystal display whose required dΔn value is only λ/4, which is one-half of a conventional FFS. Fast response time can be achieved by either decreasing the cell gap (d) or choosing a low birefringence (Δn) and low-viscosity liquid crystal. The effect of dΔn mismatch between A-film and FFS cell on contrast ratio is analysed. B...

Fast-response liquid crystals for high image quality wearable displays

We demonstrate two ultra-low viscosity liquid crystal mixtures to enable field-sequential-color wearable displays for low temperature operation, while keeping a wide color gamut. Our mixtures offer ~4X faster response time than a commercial material at 20°C and ~8X faster at −20°C. Other major attractive features include: (1) submillisecond response time at room temperature and vivid color even...
