Research

Display Circuit & System

: We develop display circuits for low-power driving.

Gate Driver Circuit

 We are developing Oxide TFT-based SCAN driver and EM driver for generating gate signals. By applying a novel structure, we aim to expand the operating range of driving circuits and minimize power consumption and layout area. 

Pixel Circuit based on LTPS/Oxide TFT

 We are developing pixel circuits for LCD and OLED display. Our work involves designing memory-integrated LCD pixel circuits that can self-refresh without additional programming. Recently, we have also concentrated on pixel circuits for OLED display.


Applied Vision for Displays

: We enhance user experience through psychophysical study.

Driving technique based on human visual system

 We proposed the peripheral dimming technique for low-power AR/VR displays. Based on the human visual system (HVS), we demonstrated that it is possible to significantly reduce power consumption while maintaining high image quality through psychophysical study. Recently, we have been researching various foveation-based techniques utilizing HVS.

Enhancing user experience

 We are developing various techniques to enhance user experience with displays. Our efforts include improving perceived image quality with psychophysical study. Our works include automatic measurement of interpupillary distance in AR/VR devices, determining the optimal brightness range for various display and lighting environments, improving touch error and cross-talk in 3D displays by leveraging dominant eye characteristics.

Micro-LED Display System

: We have proposed a novel fingerprint recognition system using micro-LED technology.

Fingerprint recognition system

 We have proposed a technique that utilizes micro-LED as optical fingerprint sensor. Based on this, fingerprint recognition can be achieved with micro-LED, without the need for separate sensors. We are continually developing this research, which is expected to significantly enhance the potential applications of micro-LEDs in the future.

Micro-LED display circuits based on TFT

 We are developing micro-LED display circuits using TFT technology. Our goal is to design TFT-based pixel circuits for micro-LED display. We are committed to advancing this technology and contributing significantly to the evolution of micro-LED displays.
