Achieving a foldable and durable OLED display with BT.2020 color space using innovative color filter structure

Abstract

A foldable active‐matrix organic light‐emitting diode display capable of enduring very severe folding and environmental impact was obtained using symmetric panel stacking with an innovative design of color filter structure. The display was subjected to in situ folding cycle under an ambient test condition of 60°C/90% relative humidity, and no performance degradation was found for the display and the touch function during and after the test. In addition, 95% coverage of BT.2020 color space was obtained without additional power consumption compared with that of the panel with National Television System Committee (NTSC) color space.

24‐4: Foldable AMOLED Display Utilizing Novel COE Structure

“…Lee, M. T. et, al. [15][16][17][18] reported symmetric panel stacking (color filter film attached to a AMOLED film) can significantly improve panel performance, flexibility and reliability compared to a C-Pol AMOLED panel.…”

Foldable display technology and wearable device integration design

“…These surface modifications paved the way for a more uniform and higher-density growth of ZnO nanorods on paper, a phenomenon substantiated by scanning electron microscopy images. To delve deeper into the structural and optical attributes of the synthesized nanostructures, a battery of analytical techniques was employed, including X-ray diffraction, X-ray photoelectron spectroscopy, and cathodoluminescence characterization [9].…”

Exploring color space: an investigation of heteroaryl-substituted benzobis[1,2-d:4,5-d′]oxazoles and their application in organic light-emitting diodes

“…19 Because these processing techniques form amorphous films, OLED devices can be made on flexible substrates for the production of bendable displays and lighting. 20 While all of these qualities are ideal for commercialization, OLEDs still suffer from lower lifetimes in contrast to their inorganic kin. Thus, research efforts towards realizing an electrochemically stable palette of emissive materials (dopants) for OLED display and solid-state lighting applications are currently being pursued.…”
