Abstract

This paper reports on a metal mask‐less lithography (MML) process for RGB OLED displays. By integrating MML, tandem OLEDs, and a microlens array (MLA), ultra‐high resolution, high luminance, and robust reliability can be realized. The report also demonstrates an MLA using an S‐stripe MLA pattern. The prototype exhibits excellent properties, with a white light efficiency of 66.7 cd/A at 15,000 cd/m². [ABSTRACT FROM AUTHOR]

Abstract

An OLED display with CAAC‐OS FETs monolithically stacked over SiFETs, capable of 32‐division control of resolution and frame rate, was fabricated. This enables display that conforms with foveal characteristics, thereby reducing the power consumed during operation. The display can be driven at 120 Hz, with reduced data transmission.

Abstract

For high‐definition microdisplays with more than several thousands of pixels per inch (ppi), c‐axis‐aligned crystal indium‐gallium‐zinc oxide (CAAC‐IGZO) field‐effect transistors (FETs) are effective devices. Based on such a viewpoint, we have fabricated a 5291‐ppi organic light‐emitting diode (OLED) display using CAAC‐IGZO FETs with a channel length of 60 nm.

Abstract

C‐axis aligned crystalline oxide semiconductor field‐effect transistor (CAAC‐OS FET) can be scaled down to a width and length of 60 nm. We have fabricated an organic light‐emitting diode (OLED) display with more than 5000 ppi, which is required in virtual reality (VR) displays, by using CAAC‐OS FETs as the backplane.

Abstract

This study aims to focus on a cover film with a considerably low Young's modulus to achieve robust and flexible displays. We fabricated a prototype flexible display with such a film on its surface and achieved a display with robustness and bendability, which can be used in various applications.
