A 400‐dpi reflective storage ferroelectric liquid‐crystal display for highly readable, low‐power mobile display applications

Abstract

Mobile products require longer battery lifetimes and increased information content from the display. A ferroelectric liquid-crystal reflective storage mode was demonstrated. This display only needs updating when the image changes, resulting in ultra-low power consumption. Passive-matrix addressing allows for high-resolution text to be displayed.

At higher concentrations, the spontaneous polarization is greater, resulting in faster switching; however, the τ min occurs at higher voltages.

P‐43: A Novel TFT Pixel Design for Active Matrix FLC with Grayscale Generation

“…Many proposed digital method to generate gray level by timemultiplex FLC pixels as high speed shutters [1] [2], but this approach poses heavy burden in driver circuit and the large loading capacitance inhering from thin cell gap also demands FLC pixel to be charged with high current, these limited the choices of source driver applicable and made it suitable only for LCOS display with driving circuit integrated to silicon panel. Our objective is to overcome this problem by designing a TFT FLC pixel that is capable to generate gray level while preserving the capability for high speed display application such as field sequential display.…”
