P-194L:Late-News Poster: Color Performance Prediction Method of Active-Matrix Liquid Crystal Display Adopting Field Sequential Driving

This paper proposes a method to predict color performance of active-matrix liquid crystal displays driven by field sequential (FS) method. Using behavioral LC model, we could simulate LC's transmittance characteristics over time. By defining turn-on timing of RGB-LEDs in FS display, we could simulate the color performances of pixels depending on their locations across the panel.

Effects of three-dimensional polymer networks in vertical alignment liquid crystal display controlled by in-plane field.

Polymer network in vertical alignment liquid crystal cell driven by in-plane field (VA-IPS) is formed in three dimensions to achieve fast response time and to keep the liquid crystal alignment even when an external pressure is applied to the cell. The network formed by UV irradiation to vertically aligned liquid crystal cell with reactive mesogen does not disturb a dark state while exhibiting very fast decaying response time less than 2ms in all grey scales and almost zero pooling mura. The proposed device has a strong potential to be applicable to field sequential display owing to super-fast response time and flexible display owing to polymer network in bulk which supports a gap between two substrates.

18.2: An EOG‐Assisted Contingent Display for Suppressing Saccadic Color Breakup

AbstractA contingent field sequential display reduces chroma to inhibit saccadic color breakup on‐the‐fly when saccadic eye movement is detected by an electro‐oculogram (EOG) sensing circuit.

Field Sequential LCD using Organic EI Backlighting

We have proposed a new field sequential full-color display composed of an optical compensated birefringent (OCB) mode, p-Si TFT LCD panel and a multicolored organic electro luminescent device (OEL). In this display system, each merits of the LC device with high-resolution capability and the OEL device with high-speed response are combined. In addition, by using synchronously scan method, we could realize the field sequential display with a conventional TFT panel. We fabricated a trial display and confirmed its promising characteristics as a field sequential full-color display in the next generation.

Single camera three-dimensional endoscope system using a ferroelectric liquid crystal device

Imaging and display systems that allow the user to obtain distance information and evaluate changes in the relative positions of objects are finding increasing numbers of applications, one area that is of increasing importance is that of stereoscopic endoscopy. Perception of depth through stereoscopic imaging has been shown to give significant improvements in the efficiency with which surgeons carry out operations. Current stereoendoscope systems utilise a two camera system combined with either dual lenses or a single lens plus image splitter system for image capture. A camera and display system is described that allows stereoscopic pairs of images to be obtained through a standard single lens endoscope using a novel electro-optic shutter combined with a standard CCD camera. The use of this ferroelectric liquid crystal shutter allows the optical path to be switched at video frame rates and offers the advantages of being lightweight, simple to drive and having no moving parts. The present system uses field sequential display of the two images combined with FELC shutter glasses to present the left and right images to the user's eyes, although ‘glasses free’ systems could be implemented directly in combination with this camera arrangement.
