70.2: An 81‐in. 8k x 4k OLED Kawara‐Type Multidisplay that Provides a Seamless, Continuous Image

Abstract

A kawara-type multidisplay providing a seamless, continuous image was fabricated by precisely arranging 13.5-inch organic light-emitting diode (OLED) flexible panels with transparent edges on two adjacent sides. By using 36 panels, an 81-inch 8k4k OLED kawara-type multidisplay, the world's largest display, was fabricated.

45-3: A Novel Seamless Kawara-type Multidisplay with Flexible OLED Panels Using an Optically Isotropic Film

“…Note that the results do not include reflection on both of the base surfaces. Although the film thickness of the passivation layers was adjusted to reduce the reflectance as much as possible [1], the reflectance in the conventional structure could not be sufficiently reduced. In contrast, the structure with a smaller difference in refractive index exhibited an extremely small reflectance in the simulation.…”

“…However, the unit panels of multidisplays typically have opaque edges, hindering the creation of a seamless image. To solve this problem, we developed and reported an 81-inch 8K Kawara-type multidisplay using 36 (6 × 6) active matrix flexible organic light-emitting diode (OLED) panels [1]. In the Kawara-type multidisplay, a unit panel has transparent edges on two adjacent sides and the transparent region overlaps the display region of an adjacent panel, allowing a seamless image to be displayed.…”

77‐4: A 2.78‐in 1058‐ppi Ultra‐High‐Resolution OLED Hybrid Display using Oxide Semiconductor/Oxide Conductor (OS/OC) Pixel (Transparent Pixel) achieving High Aperture Ratio

“…In particular, in SID2016, we reported a 1058-ppi 2.78-in flexible OLED display and proposed it as a display achieving high resolution, light weight, and a high-speed response that may be necessary for HMD displays [17]. By applying the transfer technology, we developed and reported a multidisplay fabricated by arranging plural displays [18,19] and a hybrid display in which an OLED display and a reflective liquid crystal (LC) display are formed over the same substrate [20][21][22].…”

74-1: Application of Transfer Technology to Manufacturing of Transmissive OLED and Reflective LC Hybrid (TR-Hybrid) Display

“…This study applies a transfer technology [1][2][3][4][5][6][7][8] to establish a through electrode technique in which a conductive material serving as an electrode is exposed after separation. The through electrode technique is used to expose a pixel electrode, an extraction terminal, and a common contact of a device fabricated over a separation layer on a substrate after separation.…”
