SUMMARYWe present an electrostatic tactile display for stimulus localization. The 240-Hz electrostatic force was generated by the beat phenomenon in a region where excited X electrodes cross excited Y electrodes, which presents localized tactile sensation out of the entire surface. A 10.4-in. visual-tactile integrated display was successfully demonstrated. key words: tactile display, electrostatic force, beat phenomenon, multi touch, user experience
We propose an electrostatic tactile display, which presents regional stimulation. The 240-Hz electrostatic force is generated by the beat phenomenon in a region where excited X electrodes cross excited Y electrodes, which presents tactile sensation to users. This display can accommodate multi-touch tactile interaction with visual information.Author Keywords tactile display; electrostatic; beat phenomenon; multi touch; user experience; human-computer interaction; human-display interaction.
We have successfully achieved a very high contrast ratio of over 700:1 without attaching optical compensation films. This good contrast ratio is much higher than that for commercially available projection displays whose typical contrast ratios are about 400:1. A novel light-shielding structure has been employed in order to realize the excellent performance that has been brought by suppressing low photo leakage current in the TFTs for the LCLVs.
A 0.9” XGA liquid crystal light valve with low temperature Poly‐Si TFT has been developed by using a stacked capacitor structure. The stacked capacitor structure could reduce storage capacitor area because most of the capacitor area is located above the pixel components, such as bus‐lines and TFTs. Therefore, this structure could obtain the required storage capacitance without decreasing aperture ratio. A high aperture ratio of 65% and a high contrast ratio of over 500:1 have been achieved with the fabricated light valve.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
