This paper introduces and demonstrates a display that incorporates an organic image sensor formed in the same pixel as organic light-emitting diodes through side-by-side patterning. The potential applications of this display include touch sensing, scanning, and fingerprint identification at any location on the entire display screen, without the necessity of an external module.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.

We realized a blue-phase liquid crystal display with low driving voltage and high contrast by using a liquid crystal material which is easily twisted and a protrusion electrode structure. Further, we made a prototype of a 3.4-inch panel by a novel manufacturing process suitable for a large-sized panel.

Abstract— Through the realization of a blue‐phase‐mode (hereinafter, the operational mode of liquid crystal having a blue phase is referred to as a blue‐phase mode), a display using an improved field‐sequential method was confirmed to be capable of display at a frame rate of 180 fps (field frequency of 540 Hz) or higher. Under this condition, an image without annoyance caused by color breakup was obtained. Moreover, a novel field‐sequential AMLCD integrated with a scan driver by combining the liquid‐crystal‐display (LCD) technology using blue phase and oxide‐semiconductor technology has been developed.

We fabricated a 6.05-inch reflective liquid crystal display (LCD) using a CAAC-OS for a driving transistor. We achieved low frequency driving at 1/60 fps or lower and flicker reduction. With our LCD, eye strain can be reduced more than with an electrophoretic display.

We have developed a transmissive organic light‐emitting diode (OLED) and a reflective liquid crystal (LC) hybrid display (TR‐Hybrid display). The TR‐Hybrid display serves as a reflective liquid crystal display (LCD) under external light and as an OLED display in dark environments. It exhibited superior visibility and low power consumption.
