4032 ppi High‐resolution OLED microdisplay

Abstract

A 0.5-inch Ultra Extended Graphics Array (UXGA) organic light-emitting diodes microdisplay has been developed with 6.3 μm pixel pitch. Not only 4032 ppi high resolution but high frame rate, low power consumption, wide viewing angle, and high luminance have been achieved. This newly developed organic light-emitting diodes microdisplay is suitable for Near-to-Eye display applications, especially electronic viewfinders.

59‐1: Liquid Crystal Technology for Solving Key Optical Challenges in Virtual and Augmented Realities

“…For example, for a headset with 110⁰ FOV to achieve 1 arcmin resolution, a 6K x 6K panel is required. It is quite challenging to have so many pixels within a small-size panel 8 and the electronics to drive all those pixels at the required frame rate would be very complex…”

High‐efficiency OLED microdisplay with microlens array

“…An organic light‐emitting diode microdisplay (M‐OLED) using silicon backplane to drive organic light‐emitting diode (OLED) has increasingly gained much attention due to its capability of generating high quality images that meet many of the above requirement of AR/VR system . However, the maximum luminance of M‐OLED is limited and is lower than one of micro‐/nano‐light‐emitting diode (LED) that has recently developed technology.…”

“…Virtual reality (VR) as a technology has recently become a popular topic of research, especially in the development of more realistic VR worlds requiring the fabrication of displays with higher resolutions . For example, head‐mounted displays (HMD) necessitate the use of more than 5000 pixels per inch (ppi) to prevent users from noticing the pixels at short distances.…”

“…Virtual reality (VR) as a technology has recently become a popular topic of research, 1-3 especially in the development of more realistic VR worlds requiring the fabrication of displays with higher resolutions. [4][5][6] For example, headmounted displays (HMD) necessitate the use of more than 5000 pixels per inch (ppi) to prevent users from noticing the pixels at short distances. Although recently developed small, medium, and large displays utilize field-effect transistors (FET) the size of a few micrometers, the fabrication of high-resolution displays (greater than 5000 ppi) would require the use of FETs smaller than a micrometer within the pixels.…”
