Orientation Prediction for VR and AR Devices Using Inertial Sensors Based on Kalman-Like Error Compensation

Autor: Le Thi Hue Dao, Truong Thanh Nhat Mai, Wook Hong, Sanghyun Park, Hokwon Kim, Joon Goo Lee, Min-Seok Kim, Chul Lee

Publikováno v: IEEE Access, Vol 10, Pp 114306-114317 (2022)

We propose an orientation prediction algorithm based on Kalman-like error compensation for virtual reality (VR) and augmented reality (AR) devices using measurements of an inertial measurement unit (IMU), which includes a tri-axial gyroscope and a tr

High aspect ratio microdisplay and thin optical component for glass-like AR devices

Publikováno v: Journal of Information Display, Vol 22, Iss 3, Pp 163-171 (2021)

Organic light-emitting diode (OLED) microdisplays have attracted much attention as displays for small form factor augmented reality (AR) devices. To realize glass-like thin and wide field of view (FoV) AR devices, we designed a display module with a

White organic light-emitting diode (OLED) microdisplay with a tandem structure

Autor: Hyunsu Cho, Chun-Won Byun, Chan-Mo Kang, Jin-Wook Shin, Byoung-Hwa Kwon, Sukyung Choi, Nam Sung Cho, Jeong-Ik Lee, Hokwon Kim, Jeong Hwan Lee, Minseok Kim, Hyunkoo Lee

Publikováno v: Journal of Information Display, Vol 20, Iss 4, Pp 249-255 (2019)

Microdisplay is a key technology for realizing augmented reality (AR) and mixed reality (MR) devices, which have attracted much attention of late. Even though the operating voltage in the tandem structure is higher than that in the single structure,

Device Characteristics of Top-Emitting Organic Light-Emitting Diodes Depending on Anode Materials for CMOS-Based OLED Microdisplays

Autor: Hyunkoo Lee, Hyunsu Cho, Chun-Won Byun, Chan-Mo Kang, Jun-Han Han, Jeong-Ik Lee, Hokwon Kim, Jeong Hwan Lee, Minseok Kim, Nam Sung Cho

Publikováno v: IEEE Photonics Journal, Vol 10, Iss 6, Pp 1-9 (2018)

We investigated the optical reflectance, surface roughness, and sheet resistance of aluminum (Al)/titanium nitride (TiN), titanium (Ti), and tungsten (W) layers on Si substrates, which are available in the CMOS foundry, for organic light-emitting dio

Modeling of the self-limited growth in catalytic chemical vapor deposition of graphene

Autor: HoKwon Kim, Eduardo Saiz, Manish Chhowalla, Cecilia Mattevi

Publikováno v: New Journal of Physics, Vol 15, Iss 5, p 053012 (2013)

The development of wafer-scale continuous single-crystal graphene layers is key in view of its prospective applications. To this end, in this paper, we pave the way towards a graphene growth model in the framework of the Langmuir adsorption theory an
